SOS Problem

Looking for in depth information on SOS so I know where to push.


I have a BB Bold 9700 v6 with T-Mobile.  Over the last two years I have lost much of my AT&T Roaming, where now I only get SOS service.


T-Mobile says the phone is fine, and their network is fine, and it has to be a problem at AT&T.  T-Mobile say's they have a contract, and it should work here on AT&T towers.  Their response is to call AT&T...as a TMobile customer, and ask them to support it.  I tried that a while back, and AT&T would not even talk to me as I was not a customer.  I tried again today, and actually found someone at AT&T to help.


AT&T ran some diagnostics on their towers here, including the one by my house.  They can't find anything wrong, and they too have acknowledged that I should be able to use my TMobile phone on their network here.  But all I get is SOS service.  Their thoughts are it must be a problem at TMobile.


Are there any engineers out there that truly understand the process of provisioning service while roaming?  Whos systems where would make the decision to allow or deny a phone to roam on another network? 


T-Mobile and I spent a lot of time checking settings and running tests on my phone.  They state nothing is wrong with it.  It is possible that there is a setting that controls the roaming on the phone?

Re: SOS Problem

So in your opinion, this would be a T-Mobile problem?


Just to clarify, I am a T-Mobile customer, and I am permitted to use AT&T's network, in the area I live.  This was confirmed by T-Mobile.  When I connect to the AT&T network, it goes from an "Antenna" symbol in the upper right corner, to 4 bars, then immediately to SOS.


T-Mobile is stating this isn't their problem, and that the problem is with AT&T, who says nothing is wrong with their network, and T-Mobile is refusing to return any of my calls at this time - as it isn't their problem.


Also, I have used the Blackberry desktop software to re-install the OS, without doing a backup.  Most everything was deleted in the process, which was somewhat expected, however, I was hoping to restore it to an "out of the box" status.  In any case, this has made no difference in the SOS problem.


T-Mobile is adamant that the problem is with AT&T.  They stated the phone is fine, and the SIM is fine.  Is there anything that I can get out of the phone that would provide any diagnostics to prove anything?

Re: SOS Problem



The home network is the main reason if you'll have services or not. Have you tried the SIM with another phone? It could be possible if there is a conflict with some other data on the Blackberry, such as PIN, IMEI or other personal stuffs, to reject the phone from registering.
