I manage OVMS for 6 vehicles, all use Hologram. Over the past few months I've had Hologram SIM cards 3/6 vehicles stop working, OVMS displays the following status (see screenshot below). The only fix I found for this was to replace the SIM card with a one. Has anyone else experience this? Until now all vehicles had been working fine for a number of years. Hologram are not reporting any issues on my account or with the individual SIM cards.
