Hi

I purchased the red mangOH development kit and I can not connect to the network.  
Of course, I made a complete registration according to the initial activation manual and also registered the SIM to the AirVantage site.

I send here the results of the messages presented to me:

I ask for help on the subject, I can not find the right solutionsץ

Thank you,

Hi @omri could you provide your cm info as well? If you are using a wp77xx CF3 module you might need to disable LTE-NB1 or LTE-M1 if only 2G is available. Hope it helps,  
Marc

Hi Marc,

Thank you about your comment.  
After many simulations and after replacing SIM, I noticed that the SIM must be active on the network.  
To this day I tried to work with the SIM that came with the package of mangOH Red and probably can not work with it.
