What's Happening
You've installed your eSIM, the status shows "Active," but web pages won't load and apps have no connection. This is one of the most common issues with travel eSIMs — and the good news is that 95% of cases are resolved in a few minutes without contacting support.
Root Causes
APN not configured. Most carriers push APN settings automatically when you install the eSIM profile. However, some require manual configuration. Without the correct APN, your device can see the network but can't access the internet.
Data roaming is turned off. The "Data Roaming" toggle is often disabled by default as a cost-saving measure. A foreign eSIM cannot deliver data without it, even if the profile is correctly installed.
Wrong SIM selected for data. If your device has two SIMs (physical + eSIM), mobile data may still be routed through your primary SIM instead of the new eSIM.
Carrier lock. Some devices are locked to a specific carrier and will block any other eSIM profile from accessing data services.
Step-by-Step Fix
Step 1. Enable data roaming.
- iOS: Settings → Cellular → tap your eSIM plan → enable "Data Roaming"
- Android: Settings → Network → Mobile Network → enable "Data Roaming"
Step 2. Set your eSIM as the data SIM.
- iOS: Settings → Cellular → Cellular Data → select your eSIM
- Android: Settings → SIM cards → Mobile Data → select eSIM
Step 3. Check and manually configure the APN. Find the correct APN settings on your eSIM provider's website or in the activation instructions email.
- iOS: Settings → Cellular → your plan → Network Settings → Cellular Data Network
- Android: Settings → Network → Mobile Network → Access Point Names (APN)
Enter the APN name, username, and password (if required), save, and restart your device.
Step 4. Restart your device fully. After any SIM-related settings change, do a full reboot — not just airplane mode.
Step 5. Toggle airplane mode for 30 seconds. This forces the device to re-register on the cellular network.
Step 6. Check for carrier lock.
Dial *#06# to get your IMEI, then check your device's lock status via your carrier's website or an IMEI checker service.
Frequently Asked Questions
My eSIM is active, I have signal bars, but no internet — why? Almost always it's APN settings or data roaming. Work through Steps 1–3 above.
Do I need to configure APN for every eSIM I buy? No — most major providers (Airalo, Holafly, Nomad) push APN settings automatically. Manual configuration is only needed as a fallback.
Can I use an eSIM without enabling roaming? Only if you're in the eSIM's home country. Travel eSIMs are designed for roaming, so the roaming toggle must be on.
If setup feels too complicated or your provider doesn't offer clear instructions, consider eSIMs with hassle-free automatic configuration. Browse travel eSIM plans with straightforward activation on Marix.
