Mobile data is not working in M31

[nefilla]

Hi Team,

I have recently  purchased Samsung M31 in which vodafone and airtel sim has. When I on mobile data it's  shows  me 3 line dark line out 4 but didn't  gave me that much speed of internet,  same with vodafone too. 

I thought  it would be sim issue but when I checked same sim in other phone it's  working perfectly fine.  When I went to Samsung center, after talking to them ,I feel they didn't even know resolution of it they said one software they were going to install not sure whether this issue will resolve  or not.

Can please tell me how do I resolve it
