I have updated my iphone 13 today to 16.3. After update I have problem in receiving calls, where the call is being connected to some other. But I can able to make call and I can able to receive message in my BSNL sim, but the call is not being received. Is this problem is due to my phone or the cellular network?
Hi bro, problem could be temporary with your network service provider. Do try removing and reinserting the SIM Card. If its software issue, then nothing will work. do restart your iPhone once and check too. Also call bsnl customer care once to check at their side if there is any problem with your area or number.
Let me know if that helped.
