What's the process for buying a new phone from Apple?
I'm planning on purchasing an iPhone 12 online and having it delivered to my address. My current phone (iPhone X) was paid in full and isn't on a lease.
1) I still want to keep my current phone number and cellular plan with my carrier (T-Mobile). Can I just order the iPhone 12 from Apple and buy a replacement sim from T-Mobile (I don't want to transfer the old sim to my new phone)?
2) I don't want to do a trade-in. Can I just choose the "no trade-in" option before checking out to keep my old phone?
3) Once the new phone arrives and I put in/activate the replacement sim, will my old phone automatically stop working even though it still has the old sim in it? Or do I need to contact T-Mobile to deactivate the old phone?
Basically, I don't need to transfer any data, change anything on my plan, or get credit for my old phone. All I need is a new phone, so I just don't want all the hassle of going into a T-Mobile store.
