Hi
I also have the same problem, as soon as system asked my to update new android 11 and restart my phone
My telstra 4g network no longer working, can't dial, can't sms , can't online, i tried to restart my phone a few time, nothing changes
Like Rana. does I manually change to 2/3g network only work sometimes
Please help me,
