  • OVMS and 2023 Niro
    OVMS is a not cheap module. It comes with a hologram.io SIM card, but you can use any data-only LTE plan. Cost for the module is over $250, and then you'll have to pay somewhere south of $5/mo for a data plan if you go with hologram.io. Source: about 1 year ago
  • App charge status stuck on 'loading'/'updating' message. any ideas?
    An LTE plan from hologram.io is a few bucks a month... And I'd gladly pay it and not give my money to OnStar's broken stuff :-). Source: over 1 year ago
