BYD Song Plus DM-i (Chinese Spec) Outside China – App & Master Account Setup?

I recently ordered a brand new **BYD Song Plus DM-i Smart Driving Flagship Edition (160 km)** from the UAE (Jebel Ali), **with 0 km on it**. The car will be shipped to my home country, Tunisia. I wanted to ask if anyone here already owns or has experience with **Chinese-spec versions** of this model. Specifically, what is the best way to assign the vehicle to my name and link it to the BYD app, so I can obtain the **Master Account**, without modifying the hardware or using any external solutions (such as soldering or replacing the physical SIM card)? From what I’ve heard, replacing the SIM card inside the car can lead to two main issues: 1. The BYD app may stop working, since the app (and its backend systems) identifies the vehicle using the SIM card’s ICCID. 2. The car may no longer receive OTA updates, as the system verifies both the ICCID (SIM) and the IMEI of the head unit, which must match BYD’s database before updates are pushed. If anyone has real experience with **Chinese-spec BYD vehicles used outside China**, I’d really appreciate your insights.
