New Iphone 12 Pro and new SIM card
I bought an iphone 12 pro through apple and it came with a new SIM card. I would prefer to use the new SIM card vs. the one from my iphone 6plus that I'm replacing. I can't figure out how to activate it. I've had 2 calls with customer service and one visit to an ATT store and no one has been able to tell me how to do that. When I visited the store they said to just use the old card. I'm doing that, but it's lame to use a 6 year old SIM code in a new phone. How the (Edited per community guidelines) to I activate it???
