Is your sim registered in some other state?? And which operator?? Vodafone?

[Durgeshkapoor]

No Jio and bsnl. Jio is Himachal and bsnl is punjab

And which state are you residing presently?

[Durgeshkapoor]

Punjab

Actually it happened with me when I registered the sim in one state and then moved to another state. You can just try with airtel or voda sim of Punjab for few days to know whose fault is it....sim or phone's!
