Would love to switch to a phone like this, only problem I have is text messages are inherently insecure and I would have to create a convoluted setup of texting from a devices with apps like signal and forwarding calls to this dumb device...wish there was a simple phone with a restricted build that only included signal and WhatsApp or something similar, in addition to the basic phone features.
