Lumia 900 - Unable to use phone when on 4G/LTE

A few days ago my phone would not accept or receive phone calls and not make any data connection either.

I thought maybe there was a TELUS outage in my area. The service seems to be have recovered the next day, only for this issue to come back the next day.


After going through a few options and troubleshooting seems to have isolated the issue to 4G/LTE. Any time my phones is on 4G or LTE this issue happens. If the phone gets a 3G signal its fine no issues. The phone also goes into 4G in areas there is LTE coverege even if I set the network to 3G.


The only thing I consider as the culprit is the latest version of Network Setup, as the phone was perfectly fine until I installed that. Even if I do a full reset of the phone the issues still persists.


Any one else have this problem or can some one point me in the direction of what I can do ?

Also How can I set the Network type to 3G and not make the phone pick a 4G signal ?


Firmware Number - 2175.2301.8779.12224

OS Version - 7.10.8858.136

Only the AT&T NAM variant of the Lumia 900 supports 4G/LTE and then only te bands which AT&T uses. The Global variant does not.

This is the LTE version released by Rogers in Canada. Which was unlocked and being used with TELUS.

As I have mentioned before it was working without any problems with 4G/LTE connectivity until I installed the latest Network Setup App.
