    Strict GSM - i.e. GSM DATA - is a quite dead construct because of the significant cost of paying per minute instead of paying per MB or having a fixed transfer pot per month.

    IP-based communication (GPRS, Edge, ...) would normally need a "man in the middle", i.e. a server and regular polls from each phone because of lack of fixed IP. The huge lack of IPv4 addresses requires extra charges for fixed IP numbers. And the move to IPv6 has been slow even if there are a few operators who demands IPv6 support when certifying support for phones/modules and sees IPv4 support as optional.
