BYD and TIM have signed a partnership to bring embedded connectivity to the Chinese automaker's cars in Brazil. The deal, announced on Monday (November 9), will put TIM's eSIM in around 200,000 light vehicles over the next 24 months. The cars will support remote activation of digital services. The deal also includes a dedicated 4G and 5G mobile network at BYD's industrial complex in Camaçari, Bahia.
What changes for BYD cars
The brand's models will use TIM's virtual chip, which removes the need for a physical SIM card and allows digital services to be activated remotely. The announced coverage is 4G in every Brazilian municipality and 5G in around 1,100 cities, subject to network availability. The companies have not yet detailed which features the connection will enable, nor which models will be covered first.
A dedicated network in Camaçari
The second part of the deal is the telecom infrastructure for the Camaçari industrial complex, inaugurated in October 2025 and described as BYD's largest industrial operation outside China, spanning 4.6 million square meters. The project includes seven outdoor coverage points and 63 pieces of equipment across warehouses and operational areas, to connect employees, equipment and vehicles during manufacturing.
What has not been disclosed yet
There is no detailed implementation timeline, and no confirmation on whether cars already sold will be able to receive the solution. Prices, data plans and allowances have not been disclosed either, nor has the value of the contract. For TIM, the deal expands a segment in which the operator already connects around 630,000 vehicles in Brazil through its Internet of Vehicles (IoV) solutions — it also partners with the Stellantis group, providing 4G connectivity and eSIM to Fiat, Jeep and Ram models. BYD, meanwhile, has more than 300,000 vehicles on the road in the country, according to the automaker's own data.
