I checked the SIM that you sent to me, and it's in the active state in our beta unit collection so it should not be having any problems. The device can take several minutes to connect to the cell tower--if you've seen it flash cyan that tells me that you do have service in your area. Because you have a beta Electron, it is possible that your device is missing the server keys that it needs to connect to our production device service. Try the following steps from our v048 release notes in the beta category:
1. Upgrade your CLI/Electron Firmware
First things first, please upgrade to the most recent version of the Particle CLI (
v1.8.22), which includes all of the most recent firmware binaries. Before you flash the new firmware, you're going to need the UDP Public Server Key, which is different from the TCP Public Key which is already on your Electron.
1. First, download the UDP Public Key here:
2. Next, plug your Electron in over USB, put it into DFU mode, and type the following into your terminal, which will program your device with the new UDP Public Key:
dfu-util -d 2b04:d00a -a 1 -s 3298 -D ~/Downloads/server-public-key.udp.particle.io.der
