CDMA Troubleshooting
I have the N1 model and I can’t get it activated on my carrier's network.
•
You will need to configure the MDN, MIN, and maybe more settings such as the primary and secondary
channels, and the Home SID and UID.
•
The commands are: +WMDN (MDN), +WIMI (MIN), +WPCC (Primary channel), +WSCC (Secondary
channel), +WSID (SID and UID), and +WCMT=1 (to store changes)
•
You may need more settings set, so you may need to use the WPST provisioning tool application.
(Note: N1 models are usually used for developmental purposes, so the customer will usually be working with
a carrier to get this activated on their network. It is always best for the customer to be working with the carrier
when they are activating a N1 model.)
I activated my modem but I can’t do anything with it. When I try to dial out, I get a NO CARRIER response.
•
If you are receiving a NO CARRIER response, send ‘AT+CEER’ to check the reason for no carrier, then
check the number in the Reference Guide.
•
Make sure the modem is registered and getting good signal: AT+CREG and AT+CSQ.
•
Make sure the modem is activated and provisioned correctly.
EDGE Troubleshooting
I can’t make any outgoing calls and I have a solid LS light. 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.
