In mobile cellular telephony networks like GSM and UMTS the SS7 application MAP is used. Voice connections are Circuit Switched (CS) and data connections are Packet Switched (PS) applications. Some of the GSM/UMTS Circuit Switched interfaces in the Mobile Switching Center (MSC) transported over SS7 include the following: B -> VLR (uses MAP/B).
Simjacker is a cellular software exploit for SIM cards discovered by AdaptiveMobile Security. [1] 29 countries are vulnerable according to ZDNet. [2]The vulnerability has been exploited primarily in Mexico, but also Colombia and Peru, according to the Wall Street Journal, [3] where it was used to track the location of mobile phone users without their knowledge.

The Message Transfer Part (MTP) is part of the Signaling System 7 (SS7) used for communication in Public Switched Telephone Networks. MTP is responsible for reliable, unduplicated and in-sequence transport of SS7 messages between communication partners. MTP is formally defined primarily in ITU-T recommendations Q.701, Q.702, Q.703, Q.704 and Q.705.
