iPhone 8 Plus Frozen
Hello to All, I've just bought a refurbished iPhone 8 Plus online and when I put a T Mobile prepaid SIM in there I get the "SIM Not Supported" message. In addition, my iPhone is "stuck" on the SIM Not Supported page. I tried without success to go "back", double click home button and power on/off. Any suggestions to unfreeze it ? I would like to get over to settings so I can see if it's locked down. Thanks in advance.
iPhone SE, iOS 16
