Can I put my sim card in another phone?
I have an android phone from T-mobile. I lent it to a friend to use and they dropped it. Now it wont turn on. I tried taking out the battery and sim card and putting it back. Even if i charge it still does not work. My sister has black berry storm also from T-mobile. Can i put the sim card from my android into her Black berry. Will i have to contact T-mobile informing them that i switched phones? will that affect my monthly plan?
