i used to be under under at&t and i ended up switching to tmobile .
the delima is ,i think tmobile phones suck haha .
sooo , i tried putting my tmobile sim card into my used at&t phones but it was almost as if the
phone wouldn't read the sim card .
is there a way for me to get the tmobile sim card to work in my old at&t phones ?
five stars best answer to whoever can fix my problem !!
