thats not on your service... lets read out i have cingular and i want a phone from similar to verizon or t-mobile... can i buy a phone without have to switch to that service??
Answers: OMG YES.
just dance to ebay and search the phone you want and gain it, unlock it from a store in the shopping arcade maybe and put your cingular sim card into the phone.
unfortunealyle if you enjoy verizon it doesnt use sim cards
so you cant do it with verizon.
