Maybe, but you'd be surprised what kinds of SIM application toolkit based products there are in the world. These are actually running on the SIM, with your phone only proxying input/output! For example in many African countries, you have M-Pesa [1], which was at least initially entirely based on SAT. [1] https://en.wikipedia.org/wiki/M-Pesa |
