I have two unlocked Storm2's, a Verizon and a Vodafone.

Neither of them can make or receive voice calls on T-mobile. When I try to make a call I get "No Circuit/Channel Available"

Everything else works fine on both phones, email, SMS, MMS, and web browsing.

HELP! Is anyone else having this problem? I suspect that it's a problem with OS 5.0, and not a hardware problem.

Jim:

Been asking the same question for the last two days.
Got a new SIM, no luck.
Put a "1" in front of the phone number in the service menu, no luck.
Pulled battery and waited (an hour), no luck.
Removed "Deamon.cod" file, added service books, re-added file,,,,,NO LUCK.
I have the same situation, everything else work but the phone.

Going to try and switch Modules
net_rim_bb_phone_api
net_ rim_bb_phone_app

With the 4.7 versions to see if that will patch it.

I'm having that same problem

Trying this didn't work incase anyone is interested. Loaded but no Icon available on the screen. Been forced to revert back to 4.7.
