I’m looking for recommendations. I’d like to automatically turn off my cellular modem whenever I’m attached to a good Wi-Fi signal. Airplane mode on demand.

My rationale is multiple: I’d like to save battery life when I don’t need it. I don’t need phone calls or SMS. Everything goes over the internet for me anyway.

I would like to reduce my exposure to cellular security problems, and location tracking.

Ideally whatever implements this would be open source.

— edit ---- Using the word modem was probably wrong in the post. I want to turn the cellular features off. No mobile data, no mobile phone calls, no mobile text, I would like the cellular part of the phone to be powered off.

    Unless you completely power off the radio you will still receive calls and messages. Some custom roms come with this option, but I don’t know if it’s possible to automate.

    If you want to save more power, then enabling airplane mode and then turning wifi and / or bluetooth (depending on your needs) back on should save more power.

      I’m confused by the comment. Are you saying that airplane mode still receives phone calls and messages?

        No, sorry. Airplane mode should stop all data exchange with mobile radio, but you should still be able to enable wifi and bluetooth while airplane mode is on.

        I’m pretty sure all communication with carrier is disabled when airplane mode is on, which should save more power than disabling only mobile data transfer (in this case calls and messages still get transfered and connection with carrier is active).
