I got a new iPhone 12 from T-Mobile today. I usually just move the SIM from the phone I am replacing into the new phone and good to go. The "new" SIM that came in the 12 I just pop out and leave in the box just in case.
Since these are 5G, is there any reason that I need to activate this new SIM card? Or just fine with trransferring over the old one? Thanks.
