In particular, the WiFi connection may be particularly interesting, especially in environments where GSM connectivity is not readily available, since WiFi may be cheaper to access. It also brings opportunities for the SIM card, outside of is traditional market.

I dont think that a price of such high-end sim will be enough to motivate a low-end user to buy it and have a low-end mobile with cool sensor but poor UI, instead of buying already a high-end mobile device. The low-end users do not seem to spend that much even with services that are already on the sim (such as WIB or S@T browsing).

But those can be quite interesting in the M2M business, as the sensor or wireless communication channel is closely coupled with the SIM and, therefore, can assure the security of the data.

For the banking case, it seems to me much more of a lobby problem between companies. For the life-cycle, can’t we consider adding a SIM application to the banking card? It would take as much time (or maybe a little bit more) to the bank. But concerning security it is much better then a few J2ME or other mobile banking apps, and in reality it is the same sim card providers that issues the cards for both banks and telcos.
