950XL Dual SIM with AT&T - second SIM no longer works RRS feed

  • Question

  • Case 1: with the latest update to Windows 10 mobile my second SIM no longer works. 

    Case 2: Turning off SIM 1 and SIM 2 will work, but turning back on SIM 1, it will not work.  It states no network found.

    Case 3: Turning off SIM 2 and SIM 1 will work, but turning back on SIM 2, it will not work.  It states no network found.

    is there a fix???

  • I have the 950Xl on AT&T also. The issue isn't with Windows 10 or the phone. The dual sim phone uses the 3G network for one sim and the 2G network for the other sim. AT&T disabled their 2G network.

    As you have discovered you can leave both sims in your 950XL and turn on the one that you want to use. I currently have the number for one sim permanently forwarded to the other sim until I can find a decent dual sim phone that works on AT&T. I just had a chat with AT&T and they do not have a list of dual sim phones that currently work on their network.
