Verizon supports a system that allows CDMA devices to be provisioned Over-The-Air. A CalAmp LMU-
2600™ will automatically use this system to attempt to self provision. This procedure assumes that the LMU-
2600™ has never been provisioned or activated before.
1. Power on the LMU-2600™, making sure you can observe the behavior of the Comm LED.
2. Wait until the Comm LED turns solid. This could take up to 5 minutes.
3. If after 5 minutes you observe that the Comm LED transitions from a slow blink to a fast blink
several times (i.e. more than twice) you will need to contact Verizon Wireless for further support on
account activation.
Once configured, you may verify that the LMU-2600™’s modem has registered to the CDMA network. Enter:
AT$APP COMM STATUS?
The response should be similar to:
CDMA Service:
IS-2000
Connection:
Yes
RSSI:
-80 dBm
Channel:
0
Band:Side:
800:B
Base Station ID: 0
Network ID:
0
System ID:
4
ESN (Modem S/N:
2676319948 [9F8566CC]
Phone Number:
1234567890
IMSI:
310001234567890
CarrierConfig:
5
Note that the Phone Number should match the MDN value the carrier gave you. The last 10 digits of the IMSI
field should match the MIN/MSID value they gave you.
For devices that have had previous activations, an Over-The-Air activation process may be manually started
using a single AT Command:
AT$APP MODEM UPDATE
This command is also used to initiate an Over-The-Air PRL Update for devices that are already provisioned.
Users may also force a reactivation with the command:
AT$APP MODEM ACTIVATE
Keep in mind, however, this may cause the modem to lose its credentials and become unable to register to the
network.
