SIM not registering.

I am trying to verify a SIM connection via an unlocked Android handset. The handset is a Motorola Droid 3, it is in GSM mode, the APN "neo.iot.net" has been programmed into it, and the power has been recycled. However, it is showing "no service" and no bars.

The SIM has been provisioned and set to bill, but the status in the device panel is showing "Device never registered".

My area (zip 83660) shows 3G coverage on the coverage map and I don't have any problem with cell coverage from the regular providers (Verizon, T Mobile, etc.).

What am I doing wrong?

Hi Tom,

Thanks for the post. Are you able to browse with the Neo SIM? You can type a valid URL into a browser search bar to test this.

Regards,
Bob

Thanks for the reply, Bob.

The answer is no. The attached image is what I see when I open the browser.

Hi Tom,

It looks like you're using a Verizon handset and they're a CDMA carrier. Have you tried the Neo SIM in an unlocked GSM handset?

Shoot. No, I haven't.

I'll give that a try.

Thanks,
Tom

Bob,

Even though the phone was on Verizon, I have it set to GSM only mode. Shouldn't that allow it to connect to a GSM network?

Hi Tom,

It's possible another member of the community has more information about this. In our lab we don't test GSM with a CDMA handset that's equipped with a GSM option so it's hard to give specific advice. It might be that the GSM option on your phone supports LTE but not 2G or 3G, which is required for your Neo SIM. Here are two suggestions:
  • Try a different T-Mobile SIM to see if it connects with your device
  • Get an unlocked Android handset for testing
Regards,
Bob

Bob,

Ok, I'll get a T-Mobile handset and test with that.

Bob,

Just wanted to let you know I got my device to work on the Aeris network. Evidently I wasn't giving it enough time to connect; it takes about 20 - 30 seconds. The SIM still shows it's never registered on the dashboard, but I have been able to send and receive data.

I'm trying to test connectivity. I put a neoaris SIM card (ICCID xxx2711 ) in a samsung sgh-i897. I can browse,
but not send or receive texts. I can send an SMS TO the device from the devices page, but can't send an SMS FROM the device, either to an email address or to another phone. Immense immense immense apologies if this has been covered elsewhere. Where should I look, what should I do?
