Send me a strange number with +86 before it.

The+sign here represents the number type, and 86 is the international telephone area code of China.

When making international calls, use the international area code, such as 55 in Brazil, 9 1 in India and 852 in Hong Kong.

Therefore, when making domestic calls abroad, you must add +86. Similarly, when we make an international call, we also need to add the international telephone area code of the corresponding country.

This number is pulled down by the internet. In general, the network will bring down +86, but there is no guarantee that all networks will do so. After all, it doesn't mean much to users.

As for whether the number displayed after saving comes from the network with +86 display or without +86 display, it depends on the implementation of each mobile phone manufacturer.

Suggestions don't need to be modified deliberately. For example, sometimes you dial 1795 1 to make a long-distance call, and some mobile phones are stupid, so you dial17951+86021xxxx directly, resulting in the phone being disconnected.
