Chapter 4 – Troubleshooting and Frequently Asked Questions

Frequently Asked Questions

I just received this modem, what do I need to do?

You will need to call a carrier and register the ESN number with them. Sprint models (N2) must call Sprint and Verizon models (N3) must call Verizon. Other models, N1 and N4, must contact their provider.

You must then activate the modem: We have Sprint and Verizon models that are preconfigured and just needs to run through the activation steps.

The N1 models will need more configuration using AT commands in the Reference Guide. If that doesn’t help, they may need to use the WPST provisioning tool.

The N4 model uses a RUIM card, similar to a SIM card.

Who are the carriers?

Sprint, Verizon, and Alltel.

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.

I am trying to activate my Sprint modem. When I do the ‘AT+WIOTA=1’, I get an error of 1012 back.

Please check with Sprint to make sure your ESN, MDN, and MS10 are correct. Also, make sure that the MDN and MS10 were inserted correctly into the modem.

How do I originate a voice or data call?

‘ATD<number>;’ for voice call.

‘ATD<number>’ for data call.

Why does the modem answer and then do nothing?

The modem is answering in voice mode.

If you want to answer a data call, make sure the account has CSD service.

You will need to set ‘AT+CICB=0’ to make the modem answer in data mode.

When I try to make a data connection by dialing to my analog modem from the wireless, why does the analog modem answer and send tones, but never connect?

Make sure you are using the correct dialing string. You must send ‘ATD<number>’ for a data call.

Make sure the account has CSD service.

How do I get the voice portion to work so that I can talk to others?

You will need a cable that has the speaker pins connected to a speaker and mic.

We have a “Y” cable that splits out to a RJ9 connector that can be used to plug into the receiver of a handset.

Verizon modems currently do not support voice.
