My phone does not accept or find my SIM card

Do not use SIM card adapters or SIM cards that are modified to fit into the SIM slot. If you need a SIM card of different size, contact your operator.

Try also the following:

  1. Restart your phone.
  2. Check that your SIM card is fully inserted.
  3. If possible, try your SIM card in another phone, or another SIM card in your phone.
  4. Your phone may be SIM locked, which prohibits using a SIM card from a different network operator. Contact your network operator to confirm if your phone is locked. They can provide the unlock code and instructions on how to use it.
