I suggest that you try another SIM card if possible, just to erase this possibility. And avoid manually cut SIM cards.
Ya the problem is currently I am out of town, will have to wait till I get home. I would reply once I try out other uncut micro sim. Thanks. @Quester
P.S. How to mention someone in a reply? 😛
@Naitik1210 it might be hardware related, as for mentioning someone only power users have that option, I think
Ya I guess I will take it to the sony center nearby and I hope there is some fix to it. Thanks @uliwooly
Anytime, keep us updated
I tried using other sim, and even that didn't work so I ruled out that possibilty too. I took my phone to the nearby sony centre. They said there might be a problem with the motherboard, may be because of accidental water damage (which I don't think is possible, how can water damage effect only the network?). If that's the case I will have to spend about 10-12K Indian Rupees for the new motherboard and repair. I will be informed about the actual problem in a few days, will update you with that.
