SIM unsupported on iPhone 6s

I recently bought an iPhone 6s from a friend and set it up as usual with no hiccups. However, when I inserted my T-Mobile SIM card from my current phone, I was greeted with the hello setup screen prompting me that my iPhone had successfully updated to iOS 15.7.2. After clicking "continue", it showed me the activation screen saying "it may take a few minutes to activate your iPhone". A few seconds later it showed me a screen saying "SIM not supported" with no way to exit that page (it goes away when you remove the SIM card). I looked on the T-Mobile website and inserted my IMEI code to see if my iPhone was locked under T-Mobile. It told me that my iPhone works with T-Mobile SIM cards. But when I insert my own T-Mobile SIM card, it does not accept it.

From what I just read at the T-Mobile website, the bring your own device tool doesn't check to see if the device is unlocked, just that the phone is compatible with the technology T-Mobile uses. It sounds like it's still locked to another carrier.

Do you know what carrier your friend used it with?

The previously used SIM card was an AT&T card. It didn't have any logos. I used the number combination to find out what plan was on the card. I briefly looked at the AT&T website and found no way to see if my phone is carrier locked.

You can put in an unlock request. As long as there's no outstanding balance on the phone, they'll unlock it for you if it's locked. Start here.
