Just received Ming Motorola A1200 unlocked and unbranded from ebay. ok to receive network signal I currently use t-mobile. but put in t-mobile SIM card and no network signal nor can I place and receive calls. when phone powers up just says "search...". problem?

here is what one man did to fix this problem which I think will fix yours

I'm trying to find out if the battery could possibly be the cause. The
reason being is that after shutting off and turning on the phone
several times with no success in getting a signal I put my wifes
battery into my phone and it suddenly had signal and no occurrence of
my problem. Thinking the battery may be the issue I then let the
battery run down to the point that the phone shut off (I do this
somewhat frequently) and put it on the charger and did not turn it on
until the charge was complete. At this point the problem was not
occurring until my battery was down to one bar. Then the problem
started occurring again. I then shut off the phone and put it on the
charger for awhile. I turned the phone on and sure enough I had signal.
