I have a Samsung Galaxy S22 phone with Android 13. About once or twice a month I'm facing with "no internet connection" issue while using mobile data (not a Wi-Fi). Switching off and on mobile data transfer doesn't help, but turning on Airplane mode and switching it off helps.
The question: how I can be sure is it a phone, or a carrier problem. Is it possible to find the culprit without using a SIM card from another operator?
