    I was using Windows Phone, Microsoft Lumia 535 Dual Sim, Software Windows 8. I then upgraded to 8.1.

    Then my Sim 2 slot just stopped working. What is the cause of this? Is it because Windows8.1 doesn't support dual sim or what? Please assist am frustrated.

    Have you tried to swap them? I think there is difference in Band in each sim slot.
    afaik, Lumia 535 does comes with WP8.1 not WP8, and support for dual sim is available from WP8.1 but not in WP8.
