Lost access to my Electron 3G

Troubleshooting

Electron 3G
Device OS: 0.7.0

I have an Electron 3G monitoring battery voltage (Victron MPPT solar charge controller) at our summer house in a remote location. The setup has been working flawlessly for 6 months. On startup the code reads the battery stats from the charge controller, sends them over MQTT and then goes to sleep. I’m using SYSTEM_MODE(AUTOMATIC) and 3rd party SIM.

On Thursday March 27th 11:00 EET I lost access to the device and haven’t been able to figure out what went wrong. It’s not able get a cloud connection. All I’m getting is Last Handshake: Mar 27th 2019, 11:09 am.

What I know so far:

  1. The device is registered to the network. I’m able to send a SMS message to my device and get an immediate delivery notification.
  2. According my operator’s billing stats the device is generating GPRS traffic (exactly 0.54Mb each day)

What is the status of my device? I’m presuming Mar 27th 2019, 11:09 is the last SUCCESSFUL handshake. Is there a way to find out whether there has been unsuccessful handshake attempts?

@ParticleD, or @mstanley are you able to assist?

Can you PM me the Device ID or ICCID (if it’s a Particle SIM)?

Note that our logs only go back seven days though.
