I am going to get an LG Dare, but I want to be sure I can use it with my T-Mobile SIM card. My dad told me as long as it's unlocked, I can, but I heard Verizon doesn't use SIM cards, but someone said they were able to use th LG Dare with AT&T, so I am really confused. Technically, the question I am asking is, can I use an LG Dare with a T-Mobile SIM card?
