GSM Modems & Controllers

A GSM modem is a unique kind of modem and it receives a SIM card as input. It operation is similar to that of a mobile phone in terms of a mobile operator and a required subscription. It is also quite similar to a mobile phone in terms of looks.

After being connected to a computer, the computer is able to use the modem for communication extensively over the related network. They are typically used for the provision of connectivity for mobile internet but may also be used in SMS and MMS transactions.

There are two types of functionalities that the modem can provide that is it can serve as a dedicated modem device with the usual ports or it can act like a mobile phone which enables the GSM modem functionalities.

The term GSM module is generally used as a reference for any modem that follows any of the GSM evolutionary family’s protocols.

This modem facilitates the operation of message transactions due to the provision of a special interface. The pricing on this function is done in a similar fashion to that of a mobile phone operation. To enable this feature the GSM module makes use of an “extended AT command set”.

GSM modems can be a quick and efficient way to get started with SMS, because a special subscription to an SMS service provider is not required.

These message services do not need one to subscribe specially and are independent of a SMS service provider, which is why they are quicker and more efficient. Also they prove to be cheaper than other alternatives due to the fact that the sender will pay for the transaction.

A GSM modem like the Falcom Samba 75 is an example of a dedicated modem. To start the procedure, a SIM card is inserted and the modem is then connected to the computer via any USB port.

The usage of a GSM modem is preferred over that of a GSM mobile phone due to the various existent compatibility issues caused by mobile phones. This mainly causes problems in terms of MMS messaging. This is due to the fact that, without using the modem interface for forwarding, the mobile phones automatically function on the notifications of received MMS messages.

It should also be kept in mind that only some phones enable the use of the modem interface for message transactions. The phones included in this category are mostly smart phones. And some other Nokia phones are able to make use of only one way traffic that is they can only send messages using the modem interface and cannot receive the messages.
