iphone 11 mobile connection issue - possible solution

hi there, to those of you who might hv same issue as mine on iphone 11 with mobile data connection issue, i think. hv found a way to resolve it. initially i tried to update to 17.7 but to no avail. i tried airplane mode on/off but no success. i tried date on/off still the same. i even tried resert NETWORKING but 4G Not stabe. i found out that if i turn OFF VOLTE under Mobile service> mobile data network > voice and data > volte. my 4G is more stable without the need to restart phone or turn ON/OFF aeroplane mode. pls have a try.
