no you cant put tmobile sim card into a at&t phone- since it is a different company and provider the sims cards are toatlly different
in a different phone
No its at&t. If it were a sprint phone than yes. But not from two different companies.
Yes to keep your original number you will have contact the phone company.
Yes, you can put your at&t SIM card into a GoPhone, and it will work, but if the go phone happens to be a Smart phone, and you do not call At&t and let them know and go on the internet you will be charged ALOT of internet usages!
Just let your phone read your memory card and wait.
The sim card.
You can put a Boost Mobile SIM card in a Verizon phone, but it won't work.
Depending on if you save stuff on your sim card, just take it out and put it in another phone
I dont know why but i think you can just buy an iphone off amazon.com or overstock.com and put in your own phone company sim card into it. (EX: like I could put my T-Mobile SIM card into the iPhone.) Yeah that would not be a good idea to put a different phone company sim card into another phone company phone. that person is DREAMIN!
