schmidtj Posted September 1, 2022 Share Posted September 1, 2022 I'm curious about something and figured someone on the forum would know the answer. Case in point ... 6 years ago my wife and I both got CPAP machines. Both "phone home" daily via a cellular connection for compliance and in the Settings it showed ATT 4G as the provider when we first got them. Recently I noticed my machine had more "bars" on the signal strength indicator than previously and my wife's did not change so I looked at the Cellular settings for both machines. My wife's still said ATT 4G but mine now says T-Mobile 4G. How can this change? I don't see any slot for a SIM card. The devices do have empty SD card slots and another slot about the size of an SD card also empty but the contacts don't look like a SD card. Like I said, I'm curious how a cellular provider can be changed without physical access to the device. Being the devices are 6 years old could eSim magic be the secret?

dkyeager Posted September 1, 2022 Share Posted September 1, 2022 The ability of my vehicle to get navigation signal has sometimes dramatically changed after software updates. I can only assume they reprogrammed the modem in some fashion. Quote Link to comment Share on other sites More sharing options...
