I haven’t been able to figure it out but there is an issue with Verizon where the phone “loses signalling” to receive SMS/MMS. We have been toggling Air Plane Mode to reestablish the connection. This occurs randomly. Anyone else experiencing this?
Notes:
Oneplus 6T, Oneplus 9 Pro
occurs on all /e/OS releases
did not occur on T-Mobile or AT&T
occurs on Verizon and US Mobile
occurs on 5G and 4G LTE
phone is flooded with text messages after toggling Air Plane Mode
only impacts text messages, able to receive\place calls
only clue that something is wrong is seeing a gap in text messages from folks
