Put the inactive RP sim card (any ATT sim card) in the sim card slot. Power up your phone, connect to wifi. Wait for the phone to activate. Then you can go through the usual phone setup and confirm that the phone is sim locked under general → about. Next go to Unlock Your Phone or Device - AT&T Device Unlock. Start device unlock. Do you have att phone number? No. Type in your phone’s IMEI (do NOT put IMEI 2, this is esim) then fill out your info on next page and submit. You will receive one email from at&t right away to confirm your request. Click to confirm and the second email should come soon with confirming the device is now unlocked. At this point, take out RP sim card and put a sim card for T-Mobile or Verizon (or any of their MVNOs) in the phone. Restart the device and it is now unlocked.
