LM1200 LTE Modem Red Light

[Jessec63]

I have a t-mobile straight talk plan. The sim works fine in an unlocked phone and i'm able to call/text out.

When i connected it my lm1200 I only get a red light on the wireless wan connection.

When i connected my PC to the LAN port I had to configure the APN. I got the APN info from straight talk and plugged it in and still getting the red light. It says no internet connection and when i click "connect" it says network is roaming and i click OK, but still never does connect.

Any help is greatly appreciated.

Please check whether yoru Straight Talk plan is tied to your phone. If that is the case, the network will reject it when you use it with LM1200.

Thanks
