What does a GSM modem do?

A GSM modem or GSM module is a hardware device that uses GSM mobile telephone technology to provide a data link to a remote network. From the view of the mobile phone network, they are essentially identical to an ordinary mobile phone, including the need for a SIM to identify themselves to the network.

What is the difference between GSM module and GSM modem?

A GSM module or GPRS modules are similar to modems, but there’s one difference: A GSM/GPRS Modem is an external equipment, whereas the GSM/GPRS module is a module that can be integrated within an equipment. It is an embedded piece of hardware.

How do you program a GSM modem?

Booting the GSM Module!

1. Insert the SIM card to GSM module and lock it.
2. Connect the adapter to GSM module and turn it ON!
3. Now wait for some time (say 1 minute) and see the blinking rate of ‘status LED’ or ‘network LED’ (GSM module will take some time to establish connection with mobile network)

Is GPRS the same as GSM?

1. GSM stands for Global Systems for Mobile. GPRS stands for General Packet Radio Service. GPRS is an up-gradation of GSM features over the basic features to obtain much higher data speeds and simple wireless access to packet data networks than standard GSM.
