SIM Application Toolkit (STK) is a standard of the GSM system which enables the subscriber identity module (SIM card) to initiate actions which can be used for various value-added services. [1] Similar standards exist for other network and card systems, with the USIM Application Toolkit (USAT) for USIMs used by newer-generation networks being ...
As of 2019, all available mobile phones have a proprietary baseband chip (GSM module, cellular modem), [2] [3] [4] except for the Necuno, which has no such chip and communicates by peer-to-peer VOIP. [ 5 ] [ 6 ] The modem is usually integrated with the system-on-a-chip and the memory. [ 4 ]
The first version implemented the GSM specification 21.12 and 08.5x, and worked for a specific Base Transceiver Station (Siemens BS11 MicroBTS). OpenBSC implemented several MSC components, including the A-bis protocol (the protocol between the BTS and the BSC ), AUC , HLR , VLR (both using SQL tables), and a SMS Switching Center.
The Global System for Mobile Communications (GSM) is a family of standards to describe the protocols for second-generation digital cellular networks, [2] as used by mobile devices such as mobile phones and mobile broadband modems. GSM is also a trade mark owned by the GSM Association. [3] "GSM" may also refer to the voice codec initially used ...
OMA DM specification is designed for management of mobile devices such as mobile phones, PDAs, and tablet computers. [5] Device management is intended to support the following uses:
Simulator testing is free, but installing on a device needs a fee for a developer signing key. AppCode - commercial licenses available. Since 2015, Apple allows installing the app in your own device without a developer paid membership.

The Short Message protocol itself is defined by 3GPP TS 23.040 for the Short Message Service - Point to Point (SMS-PP), [2] and 3GPP TS 23.041 for the Cell Broadcast Service (CBS).
A virtual base transceiver station (VBTS) [5] is a device for identifying the temporary mobile subscriber identity (TMSI), international mobile subscriber identity (IMSI) of a nearby GSM mobile phone and intercepting its calls, some are even advanced enough to detect the international mobile equipment identity (IMEI).
