Iphone 17 X Airtel Query

Hey Any one using Airtel on iPhone 17 Phone, Actually the issue i am facing is that Airtel is showing my Phone is not compatable for 5G , However it gets connected to 5G but did not worked , i am getting frequent issues with Internet Connectivity for AIRTEL ONLY. In there system it is showing 4G access only as well. Airtel Tech Team not able to Address and they all are clue less about how to resolve.
