My eSIM is installed but the internet does not work on iPhone. What should I do?

If your eSIM is installed on iPhone but mobile internet does not work, please check these settings first.

  1. Make sure you are in a country covered by your selected plan.
  2. Go to Settings → Cellular / Mobile Data.
  3. Make sure the Simfinity eSIM is turned on.
  4. Select Simfinity eSIM for Cellular Data / Mobile Data.
  5. Turn on Data Roaming for the Simfinity eSIM.
  6. Restart your iPhone or turn Airplane Mode on and off.
  7. Check that your plan has remaining data balance and validity.
  8. If needed, check APN settings using the APN details shown in your Simfinity account or installation email.
  9. If automatic network selection does not work, try manually selecting a supported local network.

If the internet still does not work, contact support with your order email, iPhone model, current country, ICCID if available, and screenshots of Cellular/Mobile Data, data roaming, APN, and network settings.
