Put the SIM tray back in the phone. The SIM tray can only be inserted in one direction.
- Make sure the SIM tray is completely inside the iPhone before proceeding.
Part 2 of 2: Troubleshooting SIM activation
- Connect to wireless networks. Depending on your mobile network service plan, you may not see the activation message until you connect to Wi-Fi.
Connect iPhone to iTunes on computer. If the iPhone cannot be activated via Wi-Fi, using a computer with an inernet connection will accelerate the activation process. To do this, you:- Plug the iPhone into the computer via the USB charging cable. If the program doesn't launch by itself, open iTunes.
- Wait for iTunes to activate the SIM for you.
- Reinstall iPhone. In case the iPhone just doesn't recognize the SIM card, restoring iPhone can cause the SIM card to be activated during a reset.
Use another phone to call your carrier. If your phone does not activate the new SIM card, the only way is to call the operator (eg Viettel, Vinaphone or Mobiphone). Once they verify you are the account holder, you will be able to ask them for the new SIM card; If the problem is more complicated and cannot be diagnosed over the phone, you need to bring the phone to the carrier's store to have it checked or set up for you. advertisement
