Boron 3G/LTE Europe

Hello again,

I presume you want to use your own SIM?

  1. Make sure you specify this in your code per
    https://community.particle.io/t/setting-up-a-boron-with-a-3rd-party-sim-card/45226

  2. I created a sample app to help with MNO management for Electron, it should work for Boron too once you specify the usage of the external SIM.
    https://github.com/beachviking/particle-electron-r410m-toolbox

My application allows you to go through the connection process step by step. To change MNO, run the application. Then do a modemreg command(this turns on the modem). Then you should check/set MNO as needed. I have included a method which automates this, which you can run right after the modemreg command.

Hope this helps.
