Call dropping issue

[Vydy]

I have Xperia XA bought a month back I hv a serious call dropping issue while calling particular numbers call often drops in a minute or couple of minutes and sometimes it becomes in fifth minute I verified with the network provider but no use. But this problem does not arrive in any other handsets for my same number. Pls suggest me if there is a way to solve this problem

you might have a faulty SIM card, it could be a network issue, there are myriad reasons, you could get a brand new SIM card and test it.
