Motorola Phone AT Commands
Encyclopedia
AT commands are used to control modems
to do their specified functions. Cellular phones are not much different from the old dial-up modems that are still found in many computers. This article focuses on the Motorola RAZR V3m
from Verizon and the AT commands that this phone supports and their functions. Other Motorola phones, such as the Motorola ROKR Z6m, also support some of these commands.
All of these commands are well-documented officially on the MOTODEV site, which requires registration. Though the material applies specifically to the G24, some are also relevant to other Motorola products (both GSM and CDMA).
Commands that start with AT+C are well-documented in the 3GPP
standard TS 07.07 "AT Command set for GSM Mobile Equipment (ME)", which is also an ETSI
standard and can be retrieved via their publications page.
Commands starting with AT+M are likely to be Motorola extensions.
From MODE:2, an AT+CLAC command shows the following valid commands:

Modem
A modem is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data...

| AT Command | Response from Phone | Description of command |
|---|---|---|
| AT+GMM | +GMM: Motorola CDMA V3c Rev2 Phone | Display phone model information |
| AT+MODE? | +MODE: 0 | Display current phone mode |
| AT+MODE=0 | OK | Put phone in Modem Mode |
| AT+MODE=2 | +MBAN: Copyright 2000-2004 Motorola, Inc. | Put phone in Phonebook Mode. On some models, for instance the ROKR Z6m, this allows voice dialing and SMS messages to be sent. |
| AT+MODE=8 | OK | On some P2K or P2K05 phones, puts the phone into P2K mode. This causes the current serial connection to the phone to be closed. The phone can be returned to the Modem mode by reconnecting it. |
| AT+MODE=24 | No response | Put phone in USB mass storage mode. On some models, for instance the ROKR Z6m, this allows using the phone as a USB key. |
From MODE:2, an AT+CLAC command shows the following valid commands:
