Assign a new SIM to an Electron

After purchasing a Particle Electron I set it up with a 3rd party SIM. After the 3rd party SIM stopped working I am now trying to set the Electron up to work with the SIM that it came with, however I cannot connect it to the cloud with the SIM loaded into it at the current moment. Does anyone know how to set it up so that I can activate the Particle SIM? Whenever I start it with the Particle SIM in it, it blinks green.

When switching from a 3rd party to the Particle SIM you must:

Flash a program that doesn’t set the APN. If you have the [Particle CLI] ( installed, put the Electron in DFU mode (blinking yellow) by pressing RESET and MODE at the same time, releasing RESET and continuing to hold down MODE while the LED blinks magenta until it blinks yellow, then release. Then issue the command:

particle flash --usb tinker

Then unplug the USB power and the battery and let the Electron sit for a moment. Then plug the battery and the USB back in. If you haven’t activated the SIM yet, do so at
