Can i buy a t-mobile phone and use that sim card for my unlocked phone?

Question

i have an unlocked phone and have been using at&t. i want to change to t-mobile and keep my same phone number. i also want to use my same phone but the store i went to said i have to get a phone not just a sim card.

so i was planing on getting one of the free phones and just using the sim card on my unlocked sony s500i

would that work?

Answer 1

I bought the w200a from sony and bought the sim card from t-moble. I am on pay-as-you go so the sim card was around $10. You should try another store or just go online you can purchase one online at tmoble.com

Answer 2

no they will give you a new sim card...

Answer 3

Sure, it will work because the phone is already unlocked to use AT&T or T-Mobile which are the only two companies that use sim cards.
