I have an unlocked stock rooted AT&T i747 running 4.1.2. I want to use it on the Bell network. When I put in a Bell sim, it shows it has service, and the pda.bell.ca APN shows up, but it can't find the Bell network, only Rogers. Just wondering if anyone else has tried the same thing and had success or no? As it is I cannot call, text, or browse... Please let me know if there is anything I can do.
