Boron 3th party sim connectivity problem

Hi, I have problems with 3-th party SIM and Boron. It connect for a while then disconnects then connect again etc…I am attaching screen shot of the console. I tried different keep.alive() settings also.

Thank you in advance!

When I played with this a while back, I found a keep-alive of 30 seconds to be needed for some carriers. I don’t know if any carriers go lower than that.
