Do I need upgrade SIM for 5G in new phone?
I had iPhone X. Replaced for iPhone 13pro. Transferred everything but the new phone wouldn’t connect cellular. So I put in old SIM card (from iPhone X). Everything seemed to work fine. However I cannot ever not ever have had 5G. Is this because I need my new SIM in the new phone?
u have been in areas where 5G is available and am pretty sure my settings are correct, please help
