I have a phone that i used before, then i bought a new phone. all i did was switch out the sim card. i have a new sim card that hasn't been activated yet. how do i make it active so i can use my old phone?
like this sim card might have been used before. only like when the phone was turned on...
I lost my cell phone, and i was wonderinq if i had another tmobile phone(with a sim card) if i could change them. maybe call a number and activiate it. i do have another phone, one that works and everythinq. i just need to make it activated.
