Keep the eSIM installed while you work through these checks. Deleting it can make recovery harder.

Check the plan and destination

Open the eSIM in SimFuse. Confirm that it covers your current country, has available data and has not expired. If you have not reached its coverage area, it may not connect yet.

Check the phone

  1. Enable the correct eSIM line. Match its ICCID if the label is unclear.
  2. Select it for mobile data. See "Choose the right SIM for mobile data".
  3. Enable Data Roaming for the SimFuse line as instructed. See "Turn on roaming for your SimFuse eSIM".
  4. If it shows a network but nothing loads, check the exact APN instructions. See "Check the APN for your eSIM".
  5. Briefly toggle airplane mode or restart, then test a small webpage with Wi-Fi off.

For no signal, see "No service, or connected to the wrong network". For a slow connection, see "My connection is very slow".

Still stuck?

Open support from the eSIM. Tell us your country or city, exact error and what you tried. Do not repeat steps that already failed without explaining the result.
