Airalo eSIM not Working? How to Fix It on iPhone and Android in 2026

You scanned the QR code, installed your eSIM, and landed, but mobile data isn't there. No internet, no signal, no obvious reason why. In the vast majority of cases, a few specific settings on your device are blocking the connection.

This guide covers every common reason an Airalo eSIM isn't working, walks through the troubleshooting steps for both iPhone and Android devices, and tells you exactly what to do when nothing seems to fix it.

Why is my Airalo eSIM not working?

Before working through individual fixes, it helps to understand which category your problem falls into. Most Airalo eSIM issues fit one of four patterns:

• The eSIM is installed but there's no internet. The eSIM profile is on your device, you can see it in settings, but your phone isn't routing mobile data through it. This is the most common situation and usually comes down to which SIM is set as the active data line.
• The eSIM activation process didn't complete. Something went wrong during setup, a weak Wi-Fi connection while scanning the QR code, an error message during installation, or a compatibility issue with your device. The eSIM profile may not have been installed successfully.
• The eSIM is active but data still doesn't load. Your device shows signal bars and the network name, but eSIM data isn't transmitting. Data roaming settings and APN configuration are almost always responsible here.
• The eSIM suddenly stopped working mid-trip. Data was fine, then stopped. You may have run out of data, the plan expired, or a network switch in the destination country interrupted the connection.

Work through the section matching your situation. If your eSIM is still not working after all the steps, the final sections cover escalation and alternatives.

Airalo eSIM installed but no internet

Installing the eSIM profile and actively using the eSIM are two different things. When the eSIM isn't working after installation, run through these checks before anything else.

• Set Airalo as your data line. This is the most common fix. On iPhone, go to Settings → Cellular → Cellular Data and select your Airalo line. On Android, open Settings → SIM Manager and set Airalo as the preferred mobile data SIM. If your phone is still attempting to use a physical SIM for data, your Airalo eSIM will never transmit anything regardless of other settings.
• Make sure data roaming is on. Airalo eSIMs operate as roaming connections in destination countries. Turn on data roaming for the Airalo line specifically. On iPhone: Settings → Cellular → your Airalo line → Data Roaming → toggle on. On Android: Settings → Connections → Mobile Networks → Data Roaming → enable. Without this, mobile data isn't working even when everything else is correctly configured.
• Confirm mobile data is enabled. Mobile data and data roaming are separate toggles on most devices. Make sure both are active for the Airalo line.
• Toggle airplane mode. Enable airplane mode, wait 30 seconds, then disable it. This forces your phone to reconnect to an available network and re-register the eSIM connection. It resolves a significant number of post-installation issues in under a minute.

Wait for network registration. Immediately after landing, your device needs a few minutes to automatically connect to a supported local carrier. Signal bars may appear before data actually works. Give it five to ten minutes before troubleshooting further.

How to fix Airalo not working on iPhone

iPhone handles eSIM settings through the Cellular menu. When your Airalo eSIM isn't working on an iPhone, including iPhone 13 and later models, work through these steps in order.

• Step 1: Confirm the eSIM line is active. Go to Settings → Cellular. Your Airalo eSIM should appear as a separate line. If it shows as turned off, tap it and enable it. If it doesn't appear at all, the eSIM activation process may not have completed — see the activation section below.
• Step 2: Set Airalo as the cellular data line. Under Settings → Cellular → Cellular Data, select your Airalo line. As long as your primary SIM is set here, Airalo carries no data.
• Step 3: Turn on data roaming for Airalo. Tap the Airalo line under Cellular Plans → enable Data Roaming. This single setting is responsible for a large proportion of "Airalo eSIM not working on iPhone" reports.
• Step 4: Set network selection to automatic. Go to Settings → Cellular → Network Selection → Automatic. Manually selecting a network can lock your iPhone to a carrier your Airalo plan doesn't support, causing the eSIM connection to fail entirely.
• Step 5: Check carrier settings. Go to Settings → General → About. If a carrier settings update is pending, iOS prompts you to install it. Outdated carrier settings interfere with eSIM data on some plans, install any available update before continuing.
• Step 6: Restart your device. Restarting your iPhone after changing eSIM settings applies them properly. Some settings changes don't take effect until after a full reboot.
• Step 7: Reset your network settings. If the eSIM still isn't working, go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. This clears saved Wi-Fi passwords and Bluetooth pairings but does not delete your eSIM profile. After resetting, reconfigure your data line and data roaming settings, then test again.

How to fix Airalo not working on Android

Android devices, including Samsung Galaxy models, vary in how they label eSIM settings, but the core fixes apply across most manufacturers.

• Step 1: Open SIM Manager. Go to Settings → Connections → SIM Card Manager. If you can't find it, search "SIM" in your device's settings. Confirm your Airalo eSIM shows as active. If it's toggled off, enable it.
• Step 2: Set Airalo as the mobile data SIM. Under SIM Manager, assign mobile data to your Airalo eSIM. Two active SIMs on a device default to whichever was set up first, usually the physical SIM. Until you change this, Airalo carries nothing.
• Step 3: Enable data roaming for the Airalo line. Go to Settings → Connections → Mobile Networks → Data Roaming and enable it for the Airalo line. On some Samsung Galaxy and other Android devices, this setting exists per SIM, confirm you're enabling it for Airalo specifically, not your physical SIM card.
• Step 4: Set the preferred network to LTE/4G. Go to Settings → Mobile Networks → Network Mode → LTE/4G Auto. If your device is set to 5G only and the local network your Airalo plan connects to doesn't support 5G, data will fail to connect entirely.
• Step 5: Check background data restrictions. Some Android devices restrict background data per SIM or per app. Go to Settings → Apps → and check no data restrictions apply to your mobile connection. Also check for any data saver mode limiting the Airalo line.
• Step 6: Toggle airplane mode and restart your phone. Toggle airplane mode on, wait 30 seconds, toggle off. If mobile data still isn't working, restart your device completely to reset the network connection.
• Step 7: Reset network settings. On most Android devices: Settings → General Management → Reset → Reset Network Settings. This clears network configuration without removing your eSIM profile. After resetting, reconfigure your data settings and test.

Airalo eSIM not working after arrival

If activating your Airalo eSIM worked fine but data stopped as soon as you landed, a specific set of causes applies.

Some Airalo plans only activate in the destination country. The eSIM profile installs globally, but the data plan itself doesn't become live until your device registers with a supported local carrier. This is normal. Give it five to ten minutes after landing. If data still isn't loading, toggle airplane mode. This forces your phone to reconnect actively to an available network rather than waiting for a passive registration.

Check whether your device switched back to a physical SIM after landing. Some devices revert to the physical SIM card when entering a new country, especially if the physical SIM has a roaming plan active. Verify your data line setting hasn't changed since departure.

According to Airalo's own support guidance, manually selecting a network can help when automatic connection fails. Go to Settings → Cellular → Network Selection (iPhone) or Settings → Mobile Networks → Network Operators (Android) and try selecting a network manually. Once connected, switch back to automatic. Restart your device if nothing else has worked. A full restart re-establishes the network stack and often resolves eSIM registration issues after arrival.

Airalo eSIM suddenly stopped working mid-trip

When eSIM data that was working fine suddenly stopped, check these things first.

• Check your data balance. Open the Airalo app and confirm you haven't run out of data. If your plan has a data limit and you've hit it, the eSIM connection drops until you top up or purchase a new plan.
• Check plan expiry. Airalo plans have fixed durations. If your plan period ended, data stops regardless of remaining balance. Purchase a new Airalo plan for the same destination through the app.
• Toggle airplane mode. Sometimes the eSIM connection drops when your device switches between cell towers or moves between coverage zones. Toggle airplane mode to force your phone to reconnect to a mobile network.
• Restart your device. A restart resolves most cases where the eSIM was working and then suddenly stopped without an obvious cause.
• Check for a network outage. The local network Airalo partners with in your destination may have an outage. Check the Airalo app for service notices or search for reports from other users in the same country.

How to fix Airalo eSIM activation issues

If the eSIM isn't working because the activation process itself failed, the approach differs from data troubleshooting.

• Confirm your device supports eSIM technology. Not all phones support eSIM, and some regional variants of otherwise compatible models have eSIM disabled. Verify your specific model is on Airalo's compatibility list before troubleshooting further. If your phone is unlocked but the model doesn't support eSIM, no fix exists, you need a physical SIM card instead.
• Use a stable internet connection for activation. Activating your Airalo eSIM requires a Wi-Fi connection during QR code scanning and profile installation. A weak or intermittent Wi-Fi signal during this process causes partial installations. If activation fails, delete the partial eSIM profile from your device and start again on a stronger connection.
• Check the QR code is undamaged. If you screenshotted or printed the QR code, confirm it's fully visible with no cropping or glare. Scan directly from the Airalo app's activation details screen rather than a saved image where possible.
• Request a new eSIM if the profile is corrupted. If the eSIM profile is installed but shows an error message and won't activate, contact Airalo support and request a new eSIM. Corrupted profiles don't self-repair, a fresh installation is the only fix.
• Check activation timing. Some Airalo plans have a specific activation window. If you purchased the plan significantly before your trip and the activation window closed, the plan may have expired without being used. Contact Airalo support to clarify the activation details for your specific plan.

APN settings for Airalo eSIM

APN, access point name, is the configuration your device uses to route data through a mobile network. Without the correct APN, mobile data isn't working even when every other setting is correctly configured.

Airalo eSIMs configure APN automatically in most cases. If yours didn't, or if the automatic configuration was overwritten by a carrier update, manual entry is straightforward.

Find your APN in the Airalo app. Open the app, navigate to your eSIM details, and look for network settings or APN information. Airalo lists the correct access point name for each plan.

• On iPhone: Go to Settings → Cellular → your Airalo line → APN Settings. Enter the APN exactly as shown in the app. Note: iOS sometimes restricts APN settings depending on carrier profile configuration. If the field is greyed out, contact Airalo support, the APN may need to be pushed via a carrier profile update.
• On Android: Go to Settings → Connections → Mobile Networks → Access Point Names. Add a new entry and input the APN details from the Airalo app exactly. Save and select the new APN as active.

A common APN for Airalo plans is "global", if the app shows the APN is "global", enter it exactly without quotes, spaces, or modifications. After saving, restart your device and test mobile data.

When Airalo still isn't working: what to do next?

If you've worked through every troubleshooting step and the eSIM still isn't connecting, three paths remain.

• Contact Airalo support. Reach the support team through the Airalo app or website. Include your device model, eSIM plan details, destination country, and a summary of what you've already tried. Airalo support response times vary, during peak travel periods, waits can stretch to several hours, which is a known limitation of their support structure.
• Check network status in your destination. The local carrier Airalo partners with may have an outage. This requires either waiting for the network to restore or switching to a different eSIM provider.
• Get a new eSIM from an alternative provider. If you need a stable internet connection now, adding a new eSIM from a different provider is often faster than waiting for Airalo support to resolve the issue. Most compatible devices hold multiple eSIM profiles simultaneously.

Airalo vs other eSIM providers: does reliability matter more than price?

Airalo operates as a marketplace aggregating plans from local carriers worldwide. The model delivers competitive pricing, but it also means Airalo's data quality depends entirely on whichever local partner operates in your destination. Strong in some countries, inconsistent in others.

When your eSIM isn't working and you're in an unfamiliar city, a support team with slow response times is a real problem. Airalo's support structure is built for volume. Travelers who've needed urgent help report this repeatedly.

The per-country plan structure adds its own friction. Every new destination means purchasing, installing, and managing a new eSIM plan. Frequent travelers end up with a growing list of eSIM profiles, and keeping track of which one is active becomes overhead nobody wants. Reliable alternatives worth considering:

• Yesim: one international eSIM covering 200+ countries on a single pay-as-you-go balance.
• Holafly: Holafly eSIM plans offer unlimited data with fixed durations.
• Nomad: flexible plan options with solid regional coverage.
• Saily: built-in ad-blocking and competitive mid-range pricing.

The honest summary: Airalo wins on price discovery across a wide catalog. Yesim wins on long-term usability and global simplicity. Holafly wins on unlimited data transparency. Choose based on how you actually travel.

Conclusion

Airalo eSIM not working almost always comes down to three settings: the active data line, data roaming, and APN configuration. Fix those first. Set Airalo as your mobile data SIM, turn on data roaming for the Airalo line specifically, and confirm the APN matches what the app shows. Restart your device after making changes. In most cases, one of these steps resolves the issue before you need to contact anyone.

If the eSIM still isn't connecting after working through all the troubleshooting steps, the problem is either a device compatibility issue, a local network outage, or a corrupted eSIM profile, all of which require either Airalo support or switching to a different eSIM provider.

For travelers who want to avoid this situation entirely on the next trip, the choice of eSIM provider matters as much as the plan price. One eSIM covering every destination, 24/7 support, and a single balance to manage is just a better default.
