has anyone had problems with unlocked cellphones?

Question

I'm thinking about getting an unlocked V3i Dolce & Gabbana Razr its for T-Mobile but i have Cingular

Answer 1

as long as it's unlocked, then generally T-mobile and CIngular are compatible. the only problem i ever had was switching between sprint and Cricket. the phone worked,and txt worked, but the picture messaging didnt. different systems of sending messages.

Answer 2

I have the same one.
some company dwnloads nd other stuff wont work. but you can call the cingular to fix it for you thru just calling them and they will give you instructions to upgrade
