Frequently Asked Questions
Q: What is an APN and why does my eSIM need it?
A: APN (Access Point Name) is the gateway that connects your phone to the internet through your carrier's network. Most eSIMs auto-configure APN settings, but sometimes they fail — especially on Android devices. Manually entering the correct APN fixes the 'no internet' problem in most cases.
Q: My eSIM shows signal bars but no internet. What should I do?
A: This is the most common eSIM issue. Try these steps in order: (1) Turn ON Data Roaming for your eSIM in Settings, (2) Toggle Airplane Mode on/off, (3) Check and manually enter APN settings (use our tool above), (4) Restart your phone. These 4 steps fix 95% of connectivity issues.
Q: Do I need to enter username and password for APN?
A: No. For almost all travel eSIMs, you should leave the Username and Password fields BLANK. Only fill in the APN field. Some older carrier-specific plans may require credentials, but travel eSIMs from Airalo, Holafly, Saily, Nomad, etc. do not.
Q: Why can't I find APN settings on my iPhone?
A: APN settings on iPhone are hidden when the eSIM is not actively selected. Go to Settings → Cellular → tap your eSIM → you should see 'Cellular Data Network'. If it's missing, make sure the eSIM is turned ON and selected as the data line. Some carriers lock the APN field — in that case, contact your eSIM provider.
Q: eSIM stuck on 'Activating' — is this normal?
A: Yes, if you installed the eSIM before arriving at your destination. Many eSIMs only activate when they detect the destination country's network. Install before you fly, and the eSIM will finish activating automatically when you land and turn off Airplane Mode.
Q: Why does my eSIM work on iPhone but not Android (or vice versa)?
A: Android devices are more likely to require manual APN configuration. iPhones tend to auto-configure APN settings more reliably. If your eSIM works on one device but not another, check the APN settings on the device that's not working — it's almost always the cause.
