Unfortunately, local phone numbers from your country will not work for Chinese car app registration. This applies to all countries: UAE (+971), Germany (+49), UK (+44), Canada (+1), Australia (+61), Turkey (+90) and others.
Why? Chinese car manufacturers build their apps for the domestic market. SMS gateways are configured only for Chinese +86 numbers.
The only solution is to use a Chinese +86 number. KitSim provides an eSIM with a Chinese number that receives SMS in any country.
