Mobile data disconnecting during tethering

[athav9000]

Hello there. I have a moto g6 play and use airtel 4g network. The network works fine when i use it in phone, but when i dotethering i see a "x" on my mobile network tower which shows that the mobile data is disconnected. It reconnects after a few minutes then disconnects again. This is very annoying amd i need help with it ASAP.
Ive tried contacting airtel customer care, and theve changed my apn settinga thrice. Changed my sim thrice. In adittion ive changed my apn type to "default,supl,dun,mms"
Any help would be appreciated!

Welcome to Android Central! Are you still able to use it as a tether (i.e., are you only unable to use the data on the phone while it's acting as a tether), or does it get no data whatsoever?
