Iphone 6s plus 13 iOS crushes the internet
The latest update to 13 iOS on the Iphone 6sPlus ( MKU92RU/A) crushed the internet connection ( both WiFi and mobile) except some native services like iMessenger. Push notifications receiving , but cannot send anything at all , same with the other few messengers like whatsup , viber , IMO. Safari doesn't work too. Appying to the local cell operator for the SIM-card replacement didn't help either. The light reset didn't work too. Playing with auto search of mobile operator didn't work either. No PC/MAC available for rolling back to a certain iOS version ( even if it was - I doubt these versions from 3-rd party sites are reliable enough) . Is there any other way to fix this without complete reset ?
