Please read this I don't understand

I've already asked this question on Motorola forum but I would like to hear somebody else opinion about this problem. I have a Motorola V3x unlocked phone, and it works only when I insert my SIM card which is Cingular/AT&T. When I insert my wifes SIM card (same provider) or my brothers (T-Moblie), it says "Insert SIM card". Why is that happening and anybody knows a solution for this problem?

Thanks a lot.

If It's Unlocked You Shouldn't Have Any Problems With SIMs...

You Should Try With Some Other Carriers SIM, If it Doesn't Work, It Isn't Unlocked...

Could be a SIM lock. I mean like the phone's security feature that is done by the user.

Or it just means that the phone isn't truly unlocked.

Thats a strange problem, try master resetting it or flashing see if it makes a difference.
