So I have been using a second unlocked phone (Motorola SLVR L7) for the past couple years for my US phone with a T-Mobile SIM card in it.

I just recently dug out an old Pearl 8100. Yesterday I put on 4.5.0.313/4.5.0.188 and then unlocked it today from Horizon Wireless. When I put in my T-Mobile SIM card and turn it on it goes through the usual boot up stuff and then goes on Searching for Network. After a few minutes it says No Service at the top. I know the T-Mobile SIM works because I just used it to make a call and TXT someone from the SLVR. The same goes when I put in the SIM card from my Storm2 (Rogers w/BB data plan).

What gives? Is the Pearl toast?
