Hi, I recently got an iphone 12 pro to replace my iphone X. In the past i have always just moved my sim card to my new phone and called it a day. After some reading it seems i need to use the new sim card that was included with my phone to fully utilize 5g. I have already sent my trade in X back.
I have the new sim sitting here but don’t know how to activate it. If i remove the old X sim from the 12, put the new one in, go to the tmobile and choose change/upgrade sim it tries to send a text to verify my identity which i don’t get the message because the old sim is sitting on my desk. There is a face id verification method too but that doesnt work and tries to send a text too.
So i am unsure what to do.. i tried calling support and there is a 3 hour wait to talk to someone. I know its covid, but 3 hour wait. I have been a customer 15 years and kinda disappointed with everything right now.
Any ideas would be appreciated.
