eSIM not connecting: step-by-step fixes

These steps fix 90% of eSIM connection problems. Work through them in order.

1. Check the basics:
   • Is the eSIM line active? (Settings → Mobile Data → it should show as active)
   • Is that line selected for "Mobile Data"?
   • Is "Data Roaming" enabled for that line?
2. Aeroplane Mode: enable for 10 seconds, then disable. This forces your phone to search for a network again.
3. Restart your phone: full power-off and on. Fixes most network registration issues.
4. Manual network selection:
   • iPhone: Settings → Mobile Data → your eSIM → Network Selection → turn off Automatic → pick a network manually.
   • Android: Settings → Network → SIMs → your eSIM → Network Operators → Search manually.
5. Check the APN:
   • The correct APN is usually in your order confirmation email. If it's missing: Settings → Mobile Data → your eSIM → Mobile Data Network → enter the APN manually.
   • iPhone tip: sometimes you need to "Reset Network Settings" (Settings → General → Transfer or Reset → Reset → Reset Network Settings).
6. If nothing works: contact your eSIM provider's support with your ICCID / order number. Rare, but sometimes the profile needs to be reactivated on their end.
