SPECIFICATION

The GSM Trainer is a modem or mobile equipment for transmission of voice and data calls as well as SMS (Short Message Service) in GSM Network. To control the GSM modem there is an advanced set of AT commands according to GSM European Teleommunications Standards Institute Implemented. The GSM standard has established itself across continents. The trainer is well suited for studying AT commands by camping to real networks using SIM card.
