Phone Numbers for the Wireless Modem
Every wireless modem will have its own unique phone number.
The phone number may simply be given to you by your wireless service provider or it may be on the SIM card
or both. Wireless provider implementations may vary.
Examples of Useful AT Commands
A Note About HyperTerminal
In order to verify signal strength and roaming status, you must use a terminal application such as HyperTerminal. To open this program in Windows XP or Windows 2003, go to Start > All Programs > Accessories > Communications > HyperTerminal. Other Windows operating systems have similar paths to HyperTerminal. See your system’s online Help if you cannot find it.
A Note About AT Commands
AT commands can be used to operate, configure, and query your modem. A reference guide to the GPRS commands is included on the MultiModem CD and on the Multi-Tech Web site.
The following two commands let you query signal strength and roaming status.
Verifying Signal Strength
Using HyperTerminal, type AT+CSQ The modem responds with the received signal strength (rssi). The modem responds with the received signal strength (rssi) and the channel bit error rate (ber). RSSI ranges from 0 to 31.
Signal Strength Verification – RSSI
21 – 31 Exceptional 11 - 20 Average 0 - 10 Weak or Insufficient 99 No signal
BER ranges from 0 to 7 (Seven is the highest error rate).
Checking Network Registration and Roaming Status
In this procedure, you will verify that the Wireless MultiModem has been registered on the wireless network. Using HyperTerminal, type AT+CREG? The modem will respond in one of the following ways:
Network Registration Verification
Value Network Registration Status
0,0 The modem is not registered on any network 0,1 The modem is registered on the home network 0,5 The modem is registered on a network and it is roaming
Note: If the modem indicates that it is not registered, verify the signal strength to determine if the problem
is the strength of the received signal.
Checking the Modem’s Identity
Use the ATI command (Note: This command is illustrated using the capital letter i after AT)
Type ATI0 (Note: The command ends in a zero)
The manufacturing data displays. For example: Wavecom Modem Multiband G850 1900
Type ATI3
The software version displays. For example: 651_09gg...
Type ATI6
Displays modem data features. For example: data rates, data modes, fax classes.

Initiate an emergency call
Type ATD112; (Note: Don’t forget the semicolon “;” at the end. This stands for voice calls) Responses: OK
Hang up
Type ATH Responses: OK
Establishing a Circuit-Switched Data (CSD) Connection
A Circuit-Switched Data Connection makes the wireless modem work similar to a regular analog modem. You must have CSD service in order to make a CSD call.
Note: Your wireless service provider charges airtime usage for these connections.
Establish a Connection: Using HyperTerminal or a terminal application, you can establish a CSD
connection by entering the following command: ATD<phone number>
Notes:
The phone number you are calling is entered between the displayed
brackets. Do not type additional brackets. For example, type only ATD
8585551212. 8285551212 is typed between the brackets.
This command tells the modem to inform the wireless network that you are
initiating a CSD modem call. If you are dialing to another modem, the remote modem should answer and a connection between the two modems will be established. If you include a semi-colon (;) at the end of the dialing string, the modem will instead initiate a Voice call to the phone number dialed.
Disconnect: Type: +++
Wait about two seconds to see an OK response.
Then type: ATH
Note: +++ is the escape sequence and ATH is the Hang-up command.
Answering a Circuit-Switched Data (CSD) Connection
A Circuit-Switched Data Connection makes the wireless modem work similar to a regular analog modem. You must have CSD service in order to answer a CSD call.
There are three phone numbers for GSM: the voice number, the data number, and the fax number. All are provided by the carrier. To answer a call:
Establish A Connection: Call into the modem by dialing the data number provided by your carrier. Answer a Call: When you see the RING responses on the terminal screen, enter ATA <cr> to
answer the call.
Set Auto-Answer: Enter ATS0=x
This sets the modem to auto-answer. The call will be answered after the number
of rings entered. x stand for the number rings.
Then call into the number provided to you by the carrier.
Disconnect: Type: +++
Wait about one second to see an OK response.
Then type: ATH

Chapter 3 – Using Your Wireless Modem
Internet Access
Internet access can be setup in Windows Dial-Up Networking (DUN) of the computer that the wireless modem is serving. Setup procedures will vary according to the type of wireless service provider used. To access Dial-Up Networking on your PC, go to Start > Settings > Network Connections.
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.
Connecting to the GPRS Network for Internet Access
After you have inserted the SIM card and the modem is ready for use, you can establish an Internet connection through a Windows dial-up session.
Note that your wireless provider will charge you for data usage.
Requirements
One Multi-Tech wireless GPRS modem
The GPRS modem should have an active SIM card and must have GPRS services

Chapter 4 – Troubleshooting and Frequently Asked Questions
Frequently Asked Questions
Which providers can I use?
Two major providers are T-Mobile and Cingular.
We are Cingular approved.
Does this modem support High-Speed Circuit-Switched Data (HSCSD)?
No, our GSM/GPRS modems do not support HSCSD.
The modem is answering, but seems to not be doing anything?
The modem is answering in voice mode.
If you are trying to make a data call, make sure the account has CSD service. You will also need the data
number (separate number from the main phone number that is provided by the provider).
I am trying to make a data connection by dialing from my wireless modem to an analog modem. Why does the analog modem answer and send tones, but never connect?
To make a data call you must use the ATD<number> command.
Make sure the account has CSD service.
How do I get the voice portion to work so I can talk to others using the wireless modem?
You will need a cable that has the speaker pins connected to a speaker and microphone.
We have a “Y” cable that splits out to a RJ9 connector that can be used to plug into the receiver of a
handset.
‘ATD<number>;’ will originate a voice call.
How do I make an Internet connection to my dial-up ISP?
Make sure you have CSD service.
Create a dial-up connection to the ISP’s access num ber, then use your account username and password
and choose the wireless modem as the device.
How does faxing work?
GPRS modems support Class 1 and Class 2 Group 3 faxing.
You will need fax services setup on your account. You should receive a separate phone number for fax just
like voice and data, and you must call the fax number for the modem to receive a fax.
You will also need fax software (we do not have working software). WinFax Version 10 has been tested with
success.
I can’t make outgoing calls. I just receive a NO CARRIER response.
Make sure the antenna is connected and SIM is inserted correctly.
Check signal and registration: ‘AT+CSQ’ (10-31 is good), ‘AT+CREG?’ (0,1 is registered & 0,5 is roaming).
Check NO CARRIER reason with ‘AT+CEER’. Look up error code in Reference Guide.
The modem will not answer.
To have modem autoanswer, set modem with ‘ATS0=1’ and ‘AT&W’ to store the setting.
Send ‘ATA’ to the modem once the RING is indicated on the terminal screen.
You may need to set modem to ignore DTR, ‘AT&D0’, if you aren’t providing DTR.
I am trying to make a GPRS connection using a Windows dial-up session. It connects and then immediately disconnects.
Make sure the APN is configured in the modem correctly (The APN is provided by the provider).
Check the APN with ‘AT+CGDCONT ?’ T o make sure it is correct.
If no APN is inserted, then insert the correct APN using the command ‘AT+ CGDCONT=1,”IP”,”<APN>”’ with
HyperTerminal or add it into the “Extra Initialization Commands:” in the modem’s properties.
Make sure the APN is correct for your account.
When I try to establish a GPRS connection using Windows dial-up I get an error: “Hardware Failure”.
Check the modem to make sure it is installed and can be queried in the modem’s properties.
Make sure the com port is not being held by another application. Look for the TR light indication. If it is on,
most likely another application is holding onto the port.
Make sure the dial-up connections maximum speed matches the modem’s properties maximum port speed.
Try rebooting the PC.
What is the maximum amount of characters I can use to send an SMS message?
Supports up to 160 characters maximum.
In PDU mode using 7-bit, the modem still supports 160 characters, but in 8-bit the modem will support only
70 characters.
Multi-Tech Systems, Inc. MultiModem GPRS Wireless Modem User Guide 23
Chapter 4 – Troubleshooting and Frequently Asked Questions
After changing the +CNMI, +CSCA, or +CSMP command values, the modem doesn’t store them.
When changing these command values, you must use the +CSAS command to store the changes.
How do I send an SMS message to an email account?
When sending an SMS message to an email account, you must use a designated routing number that will
tell the SMS server to route your message to an email account. Here are the numbers that we are aware of at this time:
AT&T = “0000” T-Mobile = “500” Cingular = “121”
Here is an example of how to send an SMS message to an email account:
