What is a GSM GPRS Modem Driver and Why Do You Need One?
A GSM GPRS modem driver is a software program that allows your computer to communicate with a GSM modem device over a serial, USB or Bluetooth connection. A GSM modem is a specialized type of modem that accepts a SIM card and operates over a subscription to a mobile operator, just like a mobile phone. A GSM modem can support one or more of the protocols in the GSM evolutionary family, including the 2.5G technologies GPRS and EDGE, as well as the 3G technologies WCDMA, UMTS, HSDPA and HSUPA.
A GSM GPRS modem driver enables you to send and receive SMS and MMS messages over the modem interface using an extended AT command set, as defined in the ETSI GSM 07.05 and 3GPP TS 27.005 specifications. This can be useful for applications such as NowSMS that require SMS and MMS functionality. A GSM GPRS modem driver also allows you to connect to the internet using the GPRS network, which provides data transmission at speeds up to 114 kbps. This can be useful for applications that require internet access in remote areas or where other options are not available.
How to Install and Use a GSM GPRS Modem Driver?
To install and use a GSM GPRS modem driver, you need to have a compatible GSM modem device and a SIM card with an active subscription to a mobile operator. You also need to have a Windows operating system that supports the driver. Some examples of GSM modem devices are the Falcom Samba 75, Wavecom, Multitech and iTegno. Some examples of mobile phones that support the modem interface are Nokia, Siemens, Sony Ericsson and Motorola. However, not all phones support this interface, and some may have limitations or compatibility issues with certain features. Therefore, it is recommended to use a dedicated GSM modem device rather than a mobile phone for optimal performance and reliability.
To install the driver, you need to insert the SIM card into the modem device and connect it to an available USB port on your computer. If the manufacturer provides a Windows modem driver for the device, you need to install it following their instructions. If the manufacturer does not provide a driver, you need to manually define the “Standard 33600 bps Modem” driver for the device using the Device Manager. You also need to configure the COM port settings according to the specifications of the device.
To use the driver, you need to have an application that supports the extended AT command set for sending and receiving SMS and MMS messages, such as NowSMS. You also need to have an application that supports internet access using the GPRS network, such as Internet Explorer or Firefox. You need to configure these applications with the appropriate settings for your mobile operator and your modem device. For example, you need to specify the phone number, PIN code, APN name, username and password for your SIM card. You also need to specify the baud rate, data bits, parity, stop bits and flow control for your COM port.
What are the Benefits and Risks of Using a GSM GPRS Modem Driver?
Using a GSM GPRS modem driver has some benefits and risks that you should be aware of before deciding whether to use it or not. Some of the benefits are:
You can send and receive SMS and MMS messages without requiring a special subscription to an SMS service provider. You only pay for what you use according to your mobile operator's rates.
You can access the internet using the GPRS network in areas where other options are not available or too expensive. You only pay for what you use according to your mobile operator's rates.
You can use any SIM card from any mobile operator that supports your GSM modem device. You are not locked into a specific service provider or contract.
You can use multiple SIM cards with different subscriptions or plans according to your needs. For example, you can use one SIM card for sending SMS messages and another SIM card for accessing the internet.
Some of the risks are:
You may experience lower performance or reliability compared to other options such as broadband or Wi-Fi. The speed and quality of your connection may depend on factors such as signal strength, network congestion, weather conditions and interference.
You may incur higher costs compared to other options if you use large amounts of data or send many messages. Your mobile operator may charge you per kilobyte or per message depending on your plan .
You may encounter compatibility issues with some features or applications that require specific protocols or standards that are not supported by your GSM modem device or driver .
You may expose your computer to security risks if you do not use encryption or authentication methods when connecting to the internet using the GPRS network. Your data may be intercepted or tampered with by malicious parties.
Therefore, you should weigh these benefits and risks carefully before choosing to use a GSM GPRS modem driver for your purposes.
