Use the SIM card tray or phone box.

  1. Pop out your SIM tray.
  2. Many carriers print the phone number on the SIM card sticker or the tray label.
  3. If you still have the phone box, check the barcode label. It often shows “MSISDN” or “Phone number”.
  4. Compare with another device on the same carrier to see format.
  5. Once you see it, save it in your contacts as “Me” so you avoid this problem again.
