Ditto here, 1st SIM Airtel 2nd Jio. Also, I'm facing the same issue with both. Previously Airtel network in my office at my place was superb, I used to get some MB speed even with 4G. And Jio also used to work superbly on 5G with 2 bars. Since last update I mean Feb, it's all messed up. Airtel speed in 4G has turned down to KBs % Jio shows 4G with speed in KBs. Rest everywhere(except local trains) both work fine.
I am also facing same after 21 March. I am having Samsung A33 and airtel sim. After 21 Mar 24 my phone showing no sim no service. I did reset network setting. But facing the same problem.
