Moto G 2 Gen - Mob Data is not working after the upgrade to lollipop

Hi I have Moto G 2nd Generation phone with me and I am facing a weird issue in my phone. After upgrading to lollipop version, I can't make my mobile data not working. It was previously working in KitKat version.

I contacted network providers and made sure everything is configured correctly. I also searched for a solution in Google and couldn't find a solution for this.

I want to know, whether this issue is facing by anyone and anyone knows a possible solution for this. Whether I need to contact Motorola for a solution ? Please help me to resolve this issue..
