    I recently received my Oneplus 7 Pro. I went to switch my sim card from my Oneplus 6 to my new device. I keep getting the "MM Sim not allowed" message. My carrier is MetroPCS, and I'm in the US. Any help would be appreciated.

    I also just had this error, and also have Metro PCS. You need to call Metro PCS at ‪(888) 863-8768‬ from another line, tell them you need to activate a new phone. They'll probably ask your PIN number for your account, your SIM card serial number, and the IMEI of your new phone.

    Just a switch they need to flip on their end - no problem with the phone.

    Alright nice. The help is much appreciated. It's a relief that it's not my phone, because I really didn't want to send it back, or have to get a new carrier.
