But check your warranty and then head to where the warranty is. If you are on T-mobile and they can't fix, have them suspend/credit you till it works. Don't accept it's not yours to fix.
The story is incomplete here. FOLLOW THE MONEY. WHO are you paying for this tablet?

I purchased a used samsung 7.0 original tablet android 2.2 wifi/3g t-mobile. I activated it but the network settings for the APN/Mobile networks remained greyed out. It does not connect to the network, t-mobile says it is a Samsung problem/Samsung says it is a t-mobile problem. I have reset the unit many times and theres is no change. The sim is good and the unit is not listed as stolen with t-mobile. Why does it remain greyed out? Can you help me diagnose the problem?
