I Can’t Use Remote Features on My BYD Seal U DM-i 2024 Due to Inactive SIM

I purchased a BYD Seal U DM-i 2024, expecting a smooth, tech-integrated driving experience. Unfortunately, it’s been anything but that. Although I can log into the BYD mobile app, none of the remote features work because the in-car SIM card is not active. Since March, I’ve been going in circles between BYD Efe dealership and BYD headquarters, and no one has provided a solution.

The dealership keeps blaming the lack of a service update and pushes me toward BYD central. The support team at BYD only creates service tickets and tells me I “should be able to use the app,” but in reality, there is no multimedia update on my vehicle, and nothing functions.

It's beyond frustrating that such a basic, advertised feature remains unusable for months with no concrete response or timeline. I paid for a connected car experience and received none of it.

BYD must stop giving vague answers and take responsibility. I demand an immediate update and resolution. If this can’t be fixed soon, I expect compensation or the option to return the vehicle. This is not what I signed up for.
