Q: SIM unrecognized in 5c

I recently got a phone from a friend who was using Cricket Wireless. I have recently gone to Cricket Wireless and they have confirmed that my phone has been unlocked for use with AT&T and they tested it with a Cricket SIM card to confirm that the SIM Card Reader was working properly. However, when I went to AT&T, they tested it using a working AT&T SIM card and it continued to read, "No SIM Installed". So I have an unlocked 5C with a working SIM Card reader, however it is not reading any brand new AT&T Sim cards.

I'm hesitating to restore the phone since last time I did it, I couldn't use just Wi-fi to get past the activation screen.

iPhone 5c, iOS 9.3.1

    Sorry, but unlocking only works if you erase and restore the phone:

     

    Unlock your iPhone

    First, your carrier will need to process your unlock request. Then you'll back up, erase, and restore your iPhone to unlock it.

    Start the process:

    1. See if your carrier offers unlocking. Only your carrier can unlock your iPhone.
    2. Contact your carrier and request an unlock. You might need to meet requirements to qualify for unlocking. After you submit the request to your carrier, it might take a few days to complete. Contact your carrier for the status of your unlock request.
    3. After your carrier confirms that your iPhone unlock has been processed, go to the next section.

    If you have a SIM card from a carrier other than your current carrier, follow these steps:

    1. Remove your SIM card and insert the new SIM card.
    2. Complete the setup process.

    Cricket unlocked it before and when I went to restore the phone it required my SIM card still to activate it however it wasn't reading it. Cricket claimed my iPhone was still unlocked but it wasn't working with any SIM card besides the Cricket one they tested it with at the store..
