I got a new iphone and switched my SIM card over from my old phone after I transferred everything frozen my old phone and now the new phone is in SOS mode but I am still getting calls and texts on the old phone with no SIM card.
It looks like it is using an e-sim. I am unsure how that happened when I have a physical sim. None the less when I try to transfer he e-sim from the old phone to the new phone it tells me to contact Public Mobile.
