I’ve got a few Electron’s that are being used in Malawi and couldn’t connect to the internet using the Particle SIM. I used the
clouddebug program to check for cell towers and every one of them was “unrecognized”. So, I bought a 3rd-party Airtel SIM card, set the APN, and everything worked immediately. Then, I put the Particle SIM back in and it continued to work just fine for a little while.
I know that airtel is one of Particle’s providers in Malawi, so I was wondering if I just happened to set the correct APN? Anywho, this got me to thinking: how does the Electron know which APN to use by default? Is it based on the towers (finds location and tries the different providers in the area?)? Is there a way to tell the Electron which provider to try first in hopes of connecting more quickly? The airtel APN is “internet”, which I see is the default.
