Boron is breathing white after switching back to internal sim card

Hello I’m switching Boron back to internal sim card to are able to activate in a mesh network.
After flashing the code with web ide Boron breathing white (Cellular Off?). I do factory reset, particle update nothing it stay in offline not connect to cloud.
Thanks Valentino

Solved with the following procedure:
all the step to configure 3rd party sim only the *.cpp file I use this for the internal sim
after the Boron go in listening mode (flashing blue) and for this I use this command:
echo -n -e \x01 > dummy.bin
dfu-util -d 2b04:d00d -a 1 -s 0x1fc6:leave -D dummy.bin
after a time It connect to the cloud
All best
