I had a samsung galaxy s2 (pre paid) but it wasn't working so I was thinking of buying samsung galaxy s3. Can I use my t mobile SIM card on the galaxy s3. I never used the SIM card because the phone was messed up when I got it ??
As long as the SIM card is the right size (there are different size SIMs), and if the SIM card is still activated. If the SIM card is "turned on" (active) then it may work - call T-Mobile and give them the actual # on the SIM card to see if it is activated.
if it fits then yes
