Supposedly phones remain in standby even when turned off. So either remove the battery if possible or leave them home.

Yeah always turn off your phone or any other wireless communication devices. Also, make sure any devices that you can, you should disable 2G service as just about anyone can spoof those towers these days.

Depends greatly on the phone I suppose. And most don’t have removable batteries. If that’s the case that a device stays in standby and can be activated with a transmission vs a button, then leave that device at home for sure.

If you use GrapheneOS, 2G is disabled by default!
