Yes ------
That is what I think is happening.
The phone is trying to hook up to what IT THINKS is a BB network, but it isn't.
If in Auto detect, you would think it would work it out for itself bu it isn't ( at least not everytime ) . In the " old days " it would be called a checksum issue but I do not know how to bypass this on the handheld.
In my memory , I did try to manually aquire the network, but the options given dont seem sophisticted enough to get a work around on this issue.
You get a list of networks ( all X - not avail ) except for China Mobile for the sim inserted. Selecting any other only get emergency service , I dont seem to be able to tweak the system to get a work around.
