"This is how you deliver strong security to the masses." You cannot deliver strong security on a mobile phone platform. The carrier owns you. In fact, the carrier owns you doubly over because it can control "your" computer via two pathways - with the baseband and the SIM card - both of which you have no control over. You cannot be secure on a device that a third party can interact with at the level of DMA. Further, while I keep adding a caveat about some phones whose SOC involves a baseband that is more akin to a USB modem, in terms of architecture, it turns out that even these "less terrible" SOC designs still have kind-of-sort-of ways to attain full control by the baseband over the AP. It really is that bad. You gain no protection from the carrier or a state actor that can influence the carrier, and certainly no protection from a rogue cellsite that can instruct your baseband (or your SIM) to manipulate main memory arbitrarily.
