However, once installed, data transfer is network limited to 9,600bps. The advantages with a normal modem are clear. Although you may have to purchase another connector that allows it to work with GSM phones, they will allow data transfer of 56,600bps with a landline. If you can t find a landline, use your mobile. However, once again, the speed is limited to 9,600.
Many phones come with a built in modem nowadays.
The Nokia 8210 and 8850 are the only available phones with a built in modem at the moment- and they both require infrared to work. This functional application allows phonebook management and direct SMS entry, as well as the configuration of the Internet. It acts like an emulator, converting the digital information to audible signals and sending them down the phone line. It also has fax functions, and theoretically allows you to use it as a voice modem, although I ve had no success with this function. Other suitable soft modems include TDK s GlobalPulse and SoftRadius GSM Data Software Suite.
