switching sim card into different cell phone?
ok so i have 2 phones both from tmobile. i just got the new sidekick from tmobile in June, but i kept my old phone. then i heard if u switch the sim card into my old phone it will then work again. i did this and it worked. is this bad for my phone, or will it damage it. i know that is what the workers at the phone store do when u get a new phone. will my billing be the same, like i have texting, will i be charged if i text on my old phone but put my sim card into it. also is this bad to do or against the law?

It's not bad for your phone. This is one of the great advantages of GSM technology. Use the phone you want to use.
I have about 6 GSM phones (and a bunch of SIMs for different providers) and I move them around all the time.Source(s): GSM junkie
