Cell phone question

[DennisP]

A buddy of mine just upgraded his cell phone and I was thinkiong of buying his old one. It is a samsung camera/video flip phone, he had it on cinguler and I use t-mobile. Can I just swap out the sim card?
What about unlocking it? will I have to? and is it easy to do?

Thanks in advance for any input.

it will only work with a different sim card if it's unlocked. If you don't know if it is or not, simply put your sim card in and power it up. If it gives you a sub. lock message you will need to unlock it. ussually $20 to $40 bux.
