Excuse me, what does the mobile phone number 86 that sends text messages mean at the beginning?

1, the area code of China is 0086. If you dial a number and add "0086" or "+86" before it, you will call China. Of course, if you are already in China, it is not an "international long-distance charge".

2. SMS. A number before "+86" tells you that this SMS number belongs to China. Call back this number together with the number of "+86", which is equivalent to calling "0086". Again, in China, dialing "0086" won't have side effects, but abroad, it is equivalent to making an international call to China.
