For my main use of the phone, I use a mobile eSIM, but I also add a physical prepaid SIM from Boost (Just because!) This worked fine on my S21 Ultra but now, roughly every 24 hours, suddenly complains No SIM and the SIM manager shows no physical SIM. After two or three attempts at inserting, it is recognized again. I assume this isn't a common issue or those not using esims would have complained! Anyone experienced this?
I'd recommend reaching out to Boost and seeing if they can provide you with a new SIM card first. If you are still experiencing the same situation with the new SIM, it might just be a defect on the device.
