Vehicle Module

I've had an OVMS module in my Ioniq 5 since I got it new in summer 2023. It worked fine until December 2025 (though I only noticed recently), when it stopped reporting.

I've happily been using an OVMS in my 2016 Leaf for almost a year and a half now. It's been great. But a few days ago it stopped connecting to the cellular network. All other functionality is still fine. It works as it should when it connects to my wifi. It still limits charging to my selected 'Sufficient SOC' when away from wifi too. It's just that I can't connect to it through my phone app when it's away from my home wifi. I have a Hologram SIM, with credit on the account. It has otherwise been nearly flawless since I installed it. I'm looking for some help diagnosing the problem.

Problème avec ovms, j'ai une nissan leaf 24, tout allait bien avant et j'ai fait un upgrade de batterie en 62 kwh, les commandes sont ok mais l'affichage soc batterie n'est plus reconnu maintenant.

Hello all,

I am using an Ioniq 6 in Turkiye and our cars doesnt support bluelink connection.

First I planned to build my own obd-phone device but after finding ovms, I thought it is waste of time to build it again.

I have two questions.. Mostly Ioniq 5 can messages are same with ioniq 6... Does anybody confirm it is working with Ioniq 6?

My second question.. it is forbidden to use unregistered sim modules in Turkiye.. So even if i buy a complete module , due to not registered the imei code will be in blacklist in shorttime.
