I’m wondering if it is possible to get the time from the cellular network without having to have cellular service.
This would of course be with an electron.

Hm, I wouldn’t think so…the idea of “having service” Is having a valid connection to a cellular tower, so if there’s any communication between the node and the tower then you should have a connection to the Internet.
Hi @c0t0d0s0 There is no way to do this without some sort of connection to GPS (with a GPS receiver) or internet connection (which requires a cellular connection). If you just want to maintain time after a connection though, you can use the RTC on the STM32 and make sure you provide a backup battery on VBAT in case of total loss of power.
