Hardware switch to cut power to the baseband modem

It would be so great if mudita could incorporate the ability to completely cut the power to the baseband modem via a hardware switch on the side of the mudita pure like the Librem 5 phone has recently done. This would allow for much more privacy. It’s great that the phone does not have GPS but a users location can still be known by cell tower triangulation. If one could completely kill the power to the baseband modem, therefore cutting all transmissions, the phone would be impossible to track. The current switch on the side only triggers a software / airplane mode. It does not kill power to the baseband modem and therefore it can still transmit if the code is compromised.

@kxkx I’m checking on this for you.

@kxkx Our engineers informed me that an ability to completely cut power would require hardware re-design and it is not possible at this stage. The MuditaOS will be open sourced so our community will be able to verify first-hand whether the code guarantees cutting off transmissions. Hopefully that helps.

Thank you. :blush:

What GSM modem chip have you decided to put in the phone?

@kxkx I answered the original question here: What GSM module / baseband modem? My apologies for the delayed response. I’m not sure how I missed your original post.

One of the big deciding factors on whether I will cancel my order or not is dependent on what GSM module/ baseband modem has been installed in the pure. Every other phone I’ve ever bought has always listed what GSM module/base band modem they have put in the phone prior to their release. Every other phone manufacturer in the world explicitly lists what modem they use in the specifications. Before I buy a phone I always make sure to know what this very important bit of information is. Why does Mudita have to be so secretive and not tell us what modem they have chosen??

@kxkx I understand it might be frustrating. I’m sure our engineers have their reason for this, however I have reach out to our the team team with your specific concern. I will get back to you once they come back to we with an answer.

@kxkx I asked around & I was able to find out that this is the type of modem which will be in Pure: https://www.quectel.com/UploadFile/Product/Quectel_EG25-G_LTE_Specification_V1.1.pdf Hopefully this helps.
