AT Command Info

AT commands for the GSM/GPRS wireless modem are published in a separate Reference Guide included on the product CD and posted on the Multi-Tech web site.

IP commands for GSM/GPRS modems are also published in a separate Reference Guide included on the product CD and posted on the Multi-Tech web site.

Phone Number for the Wireless Modem

Every wireless modem will have its own unique phone number.

The wireless modem’s phone number may simply be told to the subscriber or be on the SIM or both. Wireless provider implementations may vary.

Network Access

The network access arrangements to be specified in Windows Dial-Up Networking (of the computer that the wireless modem is serving) will vary according to the type of wireless service used.

For GSM-without-GPRS, a circuit-switched data connection is used. The user can set up DUN to make a conventional V.32 modem connection to any terminating modem at the other end. The phone number specified in DUN can be one supplied by the wireless service provider or another phone number related to a different dialup modem service (e.g., a dialup modem service phone number from any commercial or private dialup network).

For GSM-with-GPRS, a single DUN number is generally used by all of a wireless provider’s subscribers throughout its area of coverage (regional, nationwide, continental, etc.). Rather than being a literal phone directory number, as in conventional DUN, this is a code that gives the modem Internet access.
