So what could be the issue? Suggestions please.
Consequences be damn'ed.
I converted my Moto G XT1033 to GPE to try Paranoid Android. Carbon ROM as well. The performance was not so great so I decided to switch back to stock. And after switching back to stock, sim 2 on my XT1033 wasn't working any more. For a moment I though it would be a sim issue. But it wasn't. Helplessely, I tried switching back to GPE and and then again to stock but still SIM 2 isn't working. Sim 2 options are disabled.
