The really good hacks happen with CAMEL MAP injection. Controls all sorts of goodness like SMS, USSD, and the crown jewel: location services.
Many a "bulk SMS" provider in places like the richer carribean islands, and Indonesia that do a lot more than send spam.

- ta20240528 2y ago2G GSM piggybacked its wired backed on the ISDN telecom standard (which is which your phone number is called a MSISDN). Today's CAMEL (MAP and CAP) signalling is an evolution of the ISDN signalling which traces it roots back into (amongst others) the SINAP signalling protocol and the SS7 network stack from even before that. SS7 is early 1970s stuff. From a more innocent time.
