Vodafone India — not receiving incoming calls, not getting my data signal

Address:

Banaskantha, Gujarat, 385001

Hi
My number is [protected]. I am trying to get lte, 3g signal on my phone but it just shows signal instead if lte or 3g. I had visited the vodafone store but they were unable to get any solution. Another thing is not getting incoming calls. I can call anyone but they can't reach me. I thought it could be hardware problem but the person who checked it said that the phone is working fabulously. They said that the sim is having the problem.
Please give a solution asap.
Thanks
