I have a similar problem, also the message "phone not allowed MM6", I have a 8520 and got the 9320 from a friend. The 9320 is "locked...?" to the MTN network, thus the message phone not allowed MM6? I am currently using the Cell-C network. The 9320 works fine when I insert a MTN sim but as soon as I put in my Cell-c sim the "phone not allowed MM6" message appear and that's it - anny sugestions on how to open the network will be appreciated
I will admit it, I know very little of MTN or Cell-C, but if the device is still locked to the original carrier it will need to be unlocked to accept a another carriers SIM card.
Thousands of other threads on this if this is the cause.
Same thing occurred with my 9360 after I upgraded to the latest firmware. The Vodacom sim worked splendid for 2weeks then that error came through. The MTN still works fine but they have shoddy network in my area. MTN ddnt help rectify and getting tired of being told its a stolen phone on the forums as this is a perfectly legal handset. Have resigned to kEeping mtn on it.
