Have you tried to put the SIM card in some other modem, to get online with a PC?

I would try that, to rule out any provider problems.

It could be any number of issues including DNS failing. Can you try it in another device? From the manual the error codes are defined as:

Error #150 Unexpected response text: The http/https call succeeded, but the response was incorrect. This indicates that there is a WiFi or network login page. Such as seen in Airports, Hotels, Marinas or RV campgrounds some times. There is no solution to make the CCGX work with a WiFi network that requires such login page and/or accepting of terms of use.

Error #159 Unknown error: this is a catch-all error for errors that cannot be directly categorised. In such cases the Error message will provide information about the problem

I would be tempted to say there is some sort of filtering or proxy being done by T-Mobile on this SIM card. Have you spoken with them?

Hi bathnm,

Thanks for your response. I have a 4g modem on the way for my PC and will give that a try.

I'll give T-mobile a call as well. When I picked up the sim card it was very difficult to find someone who was knowledgeable in this matter. (no surprise there)

also thought this was interesting. I tried a SIM card from a cell phone with the same data plan and received error #153. I had the same results with a new SIM card for my personal cell. When I put in the new SIM I get error #159, #150 just like the photos above and after putting the SIM into my phone it changes to #153 and dose not recognize T-Mobile as the carrier.
