Why Frequent Travelers Are Switching to eSIM for Travel
Tired of hunting for local SIM cards the moment you land or facing sky-high roaming fees? An eSIM for travel lets you buy and activate a digital data plan online before you even board the plane. You simply scan a QR code to install it, then switch between local carriers instantly without swapping a physical card. This makes eSIM the most convenient way to stay connected abroad.
Why Digital SIMs Are Changing How We Roam
Landing in Tokyo, you no longer hunt for a plastic SIM vendor. A digital SIM, or eSIM for travel, activates the moment you step off the plane, giving you instant local data without removing your physical home card. This changes roaming because you can compare and buy a plan while still in the air, not after paying high day-pass fees at the airport kiosk. You keep two lines active on one phone, which means your home number stays on for SMS banking while the eSIM handles maps and messaging abroad. The practical shift is this: roaming now means switching providers mid-trip if one network is slow, all from a settings menu, not a store counter.
The old plastic SIM vs. the embedded alternative
The old plastic SIM requires physical insertion, removal, and careful storage when switching networks abroad. It is also tied to one carrier per card. The embedded alternative, an eSIM, is a soldered chip that stores profiles remotely. For travel, this eliminates hunting for a SIM eject tool or risking loss of the tiny card. The practical sequence: you purchase a travel eSIM plan online, receive a QR code, scan it via phone settings, and the profile installs instantly. This avoids visiting local shops or swapping cards back when you return home. The key advantage is instant carrier switching without hardware changes.
- Obtain an eSIM plan via app or website before departure.
- Scan the provided QR code with your device’s camera.
- Activate the profile in your settings, overriding the plastic SIM if desired.
- Monitor data usage in the phone’s cellular menu, with no card to remove.
How connectivity works without swapping cards
With an eSIM, connectivity is established by downloading a digital profile directly onto your phone’s embedded chip. When you travel, you activate a local or global data plan via a QR code or app, which configures the network settings remotely. Your device then communicates with local towers using that profile, exactly as a physical SIM would, but without requiring insertion or removal. The handset’s radio hardware must be carrier-unlocked to recognize these remote profiles, ensuring seamless authentication across networks. Because the profile is stored internally, you can manage multiple plans in the device’s settings and switch between them instantly—keeping your primary number active for calls while using the eSIM solely for data roaming. Remote provisioning of profile credentials thus replaces the physical act of swapping cards.
- Download a digital data profile via an app or QR code before departure.
- The device authenticates with local towers using the eSIM’s stored credentials.
- Switch between multiple eSIM profiles in the settings menu without touching hardware.
- Keep your physical SIM for voice calls while the eSIM handles roaming data.
Selecting the Best Virtual SIM Plan for Your Trip
When selecting the best virtual SIM plan for your trip, prioritize data allowances over call minutes unless you need local voice access. Check coverage maps for your exact destinations, as some eSIMs only support major cities. For short trips, a predefined regional plan often offers better value than pay-as-you-go. A common concern is whether to buy a plan before departure: Q: Should I activate my eSIM before or after landing? A: Activate before departure if your flight offers Wi-Fi, but ensure the plan’s activation window aligns with your arrival to avoid wasted days. Compare per-GB costs between global and local providers, avoiding plans with daily speed caps that degrade after a set limit.
Regional plans versus global data packages
When selecting an eSIM for travel, the core decision is between regional plans and global data packages. Regional plans target a specific continent (e.g., Europe), pooling local carrier networks for cost-effective coverage across multiple countries. They often provide higher data caps at lower prices by avoiding roaming fees across distant continents. Global packages, in contrast, offer a single plan valid on nearly every continent, prioritizing convenience over cost. They are ideal for intercontinental trips but typically charge a premium for that broad access and may throttle speeds in certain regions where local agreements are weak. Analyze your itinerary’s geographical concentration versus the number of distinct continents visited to choose the practical option.
| Aspect | Regional Plan | Global Package |
|---|---|---|
| Cost per GB | Lower (targeted network deals) | Higher (broad network access) |
| Geographic Scope | Single continent (e.g., Asia) | Multiple continents (worldwide) |
| Best Use Case | Multi-country trip within one region | Cross-continental journey |
Data caps, speed limits, and fair use policies
When selecting an eSIM for travel, scrutinize the plan’s data caps, speed limits, and fair use policies. Data caps impose a hard limit on total high-speed data; exceeding it often results in throttled speeds or outright cut-offs. Speed limits, common on “unlimited” plans, cap throughput after a threshold, making video streaming or video calls unusable. Fair use policies govern how providers treat heavy usage, such as tethering or VoIP, and may restrict prolonged high-bandwidth activity. These terms differ drastically between providers, so check the fine print for your destination.
Does an eSIM’s fair use policy affect video streaming while traveling? Yes. Many eSIMs’ fair use policies throttle speeds after a data cap is hit, reducing video to standard definition or buffering. Always verify the exact post-cap speed limit and which activities—like streaming or tethering—trigger the policy.
Top providers offering flexible short-term coverage
For travelers needing adjustable plans, top providers like Airalo, Holafly, and Ubigi excel at flexible short-term coverage. Airalo offers regional and country-specific eSIMs with validity from 1 to 30 days, allowing you to top up data on demand. Holafly specializes in unlimited data plans for fixed periods, ideal for heavy users. Ubigi provides scalable options, including a 7-day pass that can be extended. Q: Which provider offers the best refund policy for unused days? Airalo does not typically refund unused days, while Holafly offers a 30-day refund on unused plans if activated.
Setting Up a Digital Profile Before Departure
Before you leave, loading your eSIM is like packing your digital passport. Activate and test your eSIM at home while on Wi-Fi, so you aren’t fumbling with QR codes in an airport terminal. Set your phone’s data and roaming toggles immediately, then pre-label the line with your destination’s name—like “Japan Data”—to avoid confusion later. *I once watched a traveler land in Seoul with no service because she hadn’t switched her default line to the eSIM before takeoff.* A quick five-minute setup now saves that frantic post-arrival scroll through settings.
Installing the profile on an unlocked handset
Installing the profile on an unlocked handset begins by scanning the QR code from your eSIM provider directly on the device. After scanning, follow the on-screen prompts to add the cellular plan, which typically takes under two minutes. Rapid profile activation ensures you get connected immediately, bypassing physical SIM swaps. Verify that your handset’s carrier lock is fully removed before proceeding, as any residual lock can block the installation.
- Go to Settings > Cellular or Mobile Data, then select “Add eSIM.”
- When prompted, choose the provider and confirm the plan details.
- Label the new line (e.g., “Travel eSIM”) for easy management later.
- Disable the primary line if you want to avoid roaming charges on your home number.
Activating and managing multiple data profiles
Activating multiple data profiles on your eSIM lets you juggle a local plan for high-speed data alongside your home number for calls. To manage them, simply label each profile clearly—like “Spain Data” or “Home Backup”—in your device settings. Set your travel profile as the default for mobile data, but keep the other active for iMessage or two-factor authentication. Toggle between them instantly without swapping physical cards. For smooth transitions, prioritize your local data profile for internet, and disable automatic network selection to avoid roaming charges.
| Action | Travel Profile | Home Profile |
|---|---|---|
| Data Usage | Set as default | Turn off roaming |
| Calls/Texts | Optional VoIP only | Keep for 2FA/backup |
| Switching | Enable on arrival | Disable when not needed |
Troubleshooting common activation hiccups
When an eSIM fails to activate, first verify your device is connected to Wi-Fi and has no active physical SIM conflicting with the new profile. A quick restart often resolves initial provisioning issues. Ensure you scan the correct QR code or enter the activation code exactly as provided—typos are a frequent barrier. If the network remains absent, manually select the eSIM’s carrier under your mobile network settings. For stubborn cases, force a manual carrier reset by toggling airplane mode for 30 seconds.
- Restart the device after installing the eSIM profile.
- Manually choose the eSIM carrier from network settings.
- Toggle airplane mode for 30 seconds to refresh connectivity.
- Delete and reinstall the eSIM profile as a last resort.
Comparing Costs with Traditional Roaming and Local SIMs
Comparing costs, an eSIM for travel often beats traditional roaming, which can slap daily fees or per-MB charges onto your bill, quickly exceeding what you’d pay for a local plan. While a physical local SIM might offer rock-bottom prices, you face upfront time and transport costs to find a shop. An eSIM sidesteps these hidden expenses, letting you buy a data pack instantly from your couch. For short trips or multi-country itineraries, the premium on an eSIM often undercuts roaming’s unpredictable overage fees. The real value emerges when you value convenience—the cost of your time and hassle is seldom factored into the SIM card’s price sticker.
Hidden fees in carrier international plans
Carrier international plans often advertise flat daily rates, but hidden fees in carrier international plans typically emerge from fine-print surcharges. These include per-minute connection fees for calls, even if answered by voicemail, China eSIM and data throttling after a soft cap, effectively charging overage rates. Text message surcharges per picture or group SMS are common. To avoid these, always verify the fee structure by following this sequence:
- Check the plan’s deductible or “connection fee” for each call initiated.
- Confirm the exact data threshold before speed reduction and the per-MB overage cost.
- Review MMS, video messaging, and premium SMS surcharges separately.
Local SIMs or eSIM data plans eliminate these unpredictable charges by offering fixed, upfront pricing.
Breaking even: when a digital SIM saves money
The real value of an eSIM emerges at the tipping point where its cost matches a physical SIM. This eSIM breakeven point typically appears around two weeks of travel. For a 10-day trip, a $15 regional eSIM plan often beats buying a $5 local SIM plus a $30 roaming add-on. The saving kicks in because eSIMs eliminate hidden airport markups and daily activation fees. You pay one flat rate, no surprises. How quickly does an eSIM actually pay for itself? Usually by day four, when you’d otherwise pay for two separate local SIMs if hopping borders. That’s when the digital SIM transforms from convenience item to clear budget win.
Per-day pricing versus pay-as-you-go alternatives
When comparing eSIM costs, per-day plans offer predictable daily fees for a fixed data allowance, suitable for consistent usage across multiple days. In contrast, pay-as-you-go alternatives deduct from a top-up balance per megabyte or gigabyte used, ideal for minimal or sporadic data bursts. Per-day packages often become cheaper than pay-as-you-go if you exceed half your daily cap, as overage from pay-as-you-go can accumulate faster for heavier travelers. Pay-as-you-go eSIM flexibility benefits those with varied daily data needs but risks higher costs per gigabyte than a tailored per-day plan.
Q: Should I choose per-day or pay-as-you-go for a 10-day trip with heavy video calls?
A: Choose a per-day plan because its fixed cost caps daily spend regardless of high usage, while pay-as-you-go would charge per megabyte, quickly surpassing the per-day rate.
Network Performance and Coverage Abroad
When traveling, your eSIM’s network performance abroad hinges on partner carrier selection, not the eSIM brand itself. Prioritize providers that offer local network access rather than roaming on a single international backbone, as this ensures lower latency and faster data speeds. For optimal coverage, select an eSIM that automatically connects to the strongest local tower, especially in remote areas. A critical detail is to check if your eSIM supports carrier aggregation, which dramatically improves throughput in congested urban zones. Always test your connection upon arrival, and have a backup eSIM profile for regions where primary coverage is thin.
Which local carriers partner with your profile
When evaluating an eSIM for travel, the specific local carriers partnering with your profile determine actual network access in your destination. For example, an eSIM profile may partner with regional carrier networks like MTN in South Africa, Telcel in Mexico, or AIS in Thailand, not the global roaming arm of your home provider. This partnership dictates whether you connect to their 4G/5G infrastructure or fall back to slower, shared networks. Q: Which local carriers partner with my eSIM profile? Check your provider’s coverage map or user dashboard; profiles often list partnered carriers (e.g., Vodafone in Spain, Telstra in Australia) directly, ensuring you select a plan matched to the dominant local operator at your arrival airport.
4G, 5G, and stability in remote destinations
In remote destinations, 4G often provides a more reliable baseline than 5G due to its wider, more established tower coverage. While 5G promises higher speeds, its signal struggles with physical obstacles and long distances, leading to frequent dropouts in rural or mountainous regions. Network stability in remote destinations depends on the local carrier’s investment in backhaul infrastructure, not just the generation of technology. An eSIM with automatic fallback from 5G to 4G can prevent complete disconnection when signals weaken. Travelers should prioritize eSIMs that default to robust 4G networks over chasing 5G icons in areas with sparse tower density.
For remote travel stability, 4G’s wider coverage and consistent signal outpace 5G’s faster but more fragile connectivity, making reliable 4G fallback a critical eSIM feature.
Measuring real-world speeds in popular travel hubs
Measuring real-world speeds in popular travel hubs, such as airports and train stations, involves running multiple speed tests on an eSIM connection during peak congestion hours. You should compare latency for video calls and sustained download rates for streaming, as advertised speeds often collapse under hub network load. Testing at different terminal gates reveals significant variance, with concrete structures degrading signal. Use a dedicated app to log results across hubs like Heathrow or Changi, focusing on verified throughput during peak transit rather than provider claims.
Real-world hub speeds are determined by congestion and structural interference, not advertised metrics; only direct testing at peak times provides actionable performance data.
Staying Connected Across Multiple Countries
An eSIM transforms cross-border travel by letting you activate a single data plan that works seamlessly across multiple countries, eliminating the hassle of swapping physical SIMs at each border. You stay instantly connected from the moment your plane lands, without hunting for local SIM cards or overpriced roaming packages. While coverage can vary by provider, the core benefit is a consistent, local-like connection that follows your itinerary. Just be sure to check the specific country list of your plan, as some regions treat inter-country switching differently than others. This digital profile keeps your messaging apps, maps, and bookings live, turning a patchwork of destinations into a single, manageable network experience.
Seamless handoffs between borders
For travelers, auto-network switching is the core of a seamless border handoff. Instead of manually searching for a new provider, your eSIM profile instantly connects to a local tower the moment you cross a border. This eliminates dreaded “No Service” gaps and ensures navigation, messaging, and maps stay live. The transition should be silent—you only notice when your phone pings with a new carrier name. Zero-configuration connectivity is the ideal. Q: Will my data drop during the handoff? A: With a robust eSIM, the switch takes seconds and your current session—like streaming music—should resume without interruption.
Managing data usage on multi-stop itineraries
When managing data usage on multi-stop itineraries with an eSIM, prioritize regional or global plans to avoid re-purchasing a new profile at each border. Activate a single plan covering all destinations to prevent manual swaps. Before departure, download offline maps for each city and disable automatic app updates. On travel days, switch your phone to airplane mode during transit between countries to stop background data from scanning for new networks. Upon arrival, manually re-enable the eSIM within the plan’s coverage zone. For precise control, follow this sequence:
- Purchase one regional eSIM covering your entire route.
- Deactivate auto-roaming and limit app background data to essentials.
- After crossing a border, reboot your phone to force reconnection to the local network.
Avoiding surprise throttling during long journeys
To avoid surprise throttling during long journeys, choose an eSIM plan that explicitly advertises fair usage policies with high-speed data caps, not just unlimited data that slows after a few GB. Monitor your consumption via the provider’s app to pace streaming and map navigation, as crossing a threshold mid-trip can cripple connectivity. Prioritize consistent long-haul eSIM performance by selecting a regional data pack rather than switching local carriers, which often resets your allowance unfairly. Always check for “no throttling until X GB” guarantees in the fine print before departure.
Device Compatibility and Limitations
Before purchasing an eSIM for travel, you must first confirm your smartphone is carrier-unlocked and supports eSIM profiles, which is standard on recent iPhone, Google Pixel, and Samsung Galaxy models. However, many mid-range or older Android devices omit this hardware, and most U.S. carrier-locked phones (especially from Verizon or AT&T) will fail to connect to foreign networks via eSIM. A nuanced reality is that even compatible phones act as single-SIM devices when the eSIM is active, disabling your physical SIM unless your model supports Dual SIM Dual Standby. Features like Wi-Fi Calling may also vanish once you switch to the travel eSIM, forcing you to rely on VoIP apps instead.
Checking your phone for eSIM support
Before purchasing an eSIM for travel, you must verify your device supports it. Check your phone for eSIM support by navigating to Settings, then “Cellular” or “Mobile Data”, and looking for an “Add eSIM” option. Alternatively, dial *#06#; a missing EID (Electronic ID) number typically indicates no eSIM capability. Newer flagship models from Apple, Google, and Samsung generally include it, while many budget or region-specific phones do not.
- Open your phone’s settings and search for “eSIM” or “add mobile plan”.
- Look for an EID number in your phone’s “About” section or after dialing *#06#.
- Visit your manufacturer’s official website to confirm eSIM compatibility for your specific model number.
- Contact your carrier to verify if your device is unlocked and eSIM-ready for travel use.
Older devices and workaround options
Travelers with older smartphones often lack native eSIM support. A common workaround for legacy hardware involves using a physical SIM adapter or a dedicated eSIM-to-SIM converter card that writes the eSIM profile onto a programmable chip. Alternatively, some global eSIM providers sell a physical SIM that replicates the software functionality. The success rate of these adapters varies significantly by device model and firmware version. To activate a workaround, follow this sequence:
- Select an eSIM provider that offers a companion physical SIM or adapter.
- Insert the adapter into the phone’s SIM tray, ensuring contact alignment.
- Scan the provider’s QR code or enter the activation code manually.
- Select the new data plan in your device’s cellular settings.
What to do if your handset lacks the feature
If your handset lacks eSIM, your travel connectivity isn’t blocked. You can use a physical travel SIM card from the same eSIM provider—many now ship a nano-SIM to your home or offer a pickup at your destination. Alternatively, purchase a local prepaid SIM upon arrival at the airport or a mobile shop. Some providers also let you manage a physical SIM via the same app you’d use for eSIM, keeping your plan and pricing identical. For multi-device travelers, you could hotspot from a companion’s eSIM-enabled device. A simple USB dongle that accepts a SIM can also convert your laptop into a temporary hotspot.
Security and Privacy While Using Remote Profiles
The first time I activated an eSIM for a trip to Lisbon, I wasn’t just avoiding a physical SIM swap—I was consciously stepping into a more secure setup. Remote profiles are isolated from your primary line, meaning a compromised travel eSIM can’t access your home number’s messages or banking apps. I later realized that eSIMs eliminate the risk of a physical card being cloned or lost at a café or border crossing. Still, one nuance stuck with me: only download official operator apps over a trusted network before you leave, because a spoofed QR code on a public Wi-Fi can still hand over your profile data to a malicious actor. This digital wall between home and travel identities remains my strongest privacy tool.
Encryption standards and data handling
When using an eSIM for travel, your critical data is secured through AES-256 encryption standards, the same protocol used by financial institutions. This ensures your personal information and network credentials are scrambled during activation and session handling. A clear sequence governs data transmission:
- Your device generates a unique cryptographic key stored locally.
- The remote eSIM profile is downloaded via a TLS-encrypted tunnel.
- All subsequent network authentication packets are encrypted with session-specific keys.
No user data is stored on the carrier’s cloud server after the initial provisioning handshake, meaning local handling on your device is the only persistent footprint.
Risks of public Wi-Fi vs. cellular data alternatives
Public Wi-Fi exposes travelers to man-in-the-middle attacks and data interception, as networks often lack encryption. Using an eSIM’s cellular data alternative bypasses these risks entirely by creating a private, encrypted tunnel from device to carrier. eSIM cellular connections eliminate the need to authenticate on unknown routers. When you lack cellular signal, follow this risk hierarchy:
- Activate your eSIM data plan.
- Use a trustworthy portable hotspot with a SIM.
- Avoid free Wi-Fi; if unavoidable, connect through a reputable VPN.
The cellular path reduces attack surface by removing shared network vulnerabilities.
Protecting your primary number during travel
When traveling, protecting your primary number is best achieved by installing a secondary eSIM profile for data, then disabling the primary SIM in your device settings. This prevents your home carrier from triggering international roaming fees or exposing your number to local networks. You can still receive SMS via Wi-Fi Calling if your carrier supports it, but calls and data route through the travel eSIM. Never share your primary number with foreign services; keep it offline unless needed for two-factor authentication.
| Aspect | Protecting Primary Number |
|---|---|
| Active during travel | Disabled (off/airplane mode) |
| Data usage | Routed through travel eSIM only |
| Inbound calls/SMS | Wi-Fi Calling or no service |
| Risk to primary number | Minimized by no network exposure |
Managing Multiple Lines on One Device
With an eSIM for travel, managing multiple lines on one device becomes straightforward. You can keep your primary home number active for calls and SMS while adding a travel eSIM with a local data plan. The device’s settings let you assign specific functions to each line, such as using the travel eSIM exclusively for cellular data. This eliminates the need to swap physical SIMs, so your home number remains reachable during your trip. You can also toggle lines on or off as needed to avoid roaming charges, and easily switch data sources between lines without any hardware changes. This setup ensures seamless connectivity without forfeiting your existing number.
Keeping a home number active alongside a travel plan
Keeping a home number active alongside a travel plan is essential for receiving bank verification codes and two-factor authentication messages. You can maintain domestic connectivity by switching your primary line to a secondary device or using a dual active eSIM phone. Set your home line to forward calls to a VoIP app to avoid roaming charges. Alternatively, configure your home carrier’s eSIM to use data-only mode while a travel eSIM handles internet; calls and texts remain live. A quick settings toggle ensures the home number never misses critical alerts without incurring runaway fees.
Switching between profiles for work and leisure
Switching between profiles for work and leisure on a single eSIM device becomes effortless when traveling. You can instantly deactivate your work profile during off-hours, silencing intrusive notifications and preventing burnout, while activating a separate leisure profile for local data and entertainment apps. This frictionless toggle eliminates the need to carry multiple phones or swap physical SIMs. The key benefit is maintaining a clear boundary between professional obligations and personal relaxation, all managed through your device’s settings. By doing so, you preserve battery life and focus, making your trip both productive and restorative without compromising connectivity. This seamless profile switching transforms your eSIM into a travel essential for balanced digital boundaries.
Balancing dual-SIM setups for constant reachability
Balancing dual-SIM setups for constant reachability requires assigning your primary number to the physical SIM for stable incoming call forwarding, while keeping the eSIM active for local data. Configure your device to route voice calls through the home SIM and data exclusively to the travel eSIM. This prevents missed calls from your home number while avoiding roaming data charges, but demands careful manual selection of default lines for contacts. Most modern phones allow simultaneous standby for both SIMs, ensuring alerts from either line appear instantly.
| Aspect | Primary SIM (Physical) | Travel eSIM |
|---|---|---|
| Voice & SMS | Default for inbound/outbound | Disabled (unless manual) |
| Data | Disabled | Always active |
| Reachability | Call forwarding to voicemail optional | Data for messaging apps |
Emergency and Backup Connectivity Tips
When traveling, emergency eSIM backup is your lifeline. Before departure, install at least one secondary eSIM on your device, ideally from a different global provider than your primary data plan. For critical connectivity, activate a low-cost, 24-hour pass as a fallback; this ensures immediate access to maps, messaging, and emergency contacts if your main eSIM fails or has poor signal. Always screenshot your eSIM activation QR codes and provider support numbers, storing them offline. To preserve backup data, disable automatic updates and background app refresh. For worst-case scenarios, pre-download offline maps and translation packs. This layered approach guarantees you remain reachable during any travel disruption, avoiding total communication blackouts.
Storing offline maps and critical contacts
Before activating your travel eSIM, preload offline maps for every destination, as data gaps can occur upon arrival. Save critical contacts like your hotel, embassy, and local emergency services directly to your phone’s memory, not just the cloud. This ensures you navigate and call for help even during initial eSIM setup or roaming delays.
- Download Google Maps or Maps.me offline regions for entire cities or countries.
- Store emergency numbers (police, ambulance) with country codes in your favorites.
- Save a screenshot of your eSIM activation details and your hotel address for offline access.
Using your profile for VoIP calls abroad
When using an eSIM for travel, your data profile becomes your primary connection for making VoIP calls abroad. Activate your eSIM’s data plan, then ensure your VoIP app (like Skype or WhatsApp) is set to “Use Cellular Data” or the eSIM’s line. For stable calls:
- Disable Wi-Fi calling on your physical SIM to prevent carrier charges.
- In your phone’s settings, designate the eSIM as the default for mobile data.
- Open your VoIP app and test audio quality over the eSIM’s network; lower video resolution if lag occurs.
Your eSIM profile keeps your local number dormant for data-only use, ensuring VoIP calls route through the internet without incurring roaming fees.
What happens when you run out of data mid-trip
Running out of data mid-trip with an eSIM means immediate loss of navigation, translation, and ride-hailing apps. Your phone stays on, but connectivity vanishes. To regain access, you must top up through your eSIM provider’s app or website using any available Wi-Fi, like a café or hotel. This is why eSIM data top-up is your single fastest solution; purchase a small additional plan within minutes to restore full service. Without a digital backup method, you rely solely on finding local SIM cards, wasting precious travel time. Always verify your provider allows instant credit top-ups before departure to avoid being stranded offline.
