0086 harassing text messages

+stands for international prefix, just like dialing+or 00 when making an international call with a mobile phone, and 86 stands for China. When calling back to China from abroad, you should dial +86 or 0086 first. Generally, it can be omitted in China, but it doesn't hurt to add one, which makes the telephone number unique and complete in the world. Therefore, the mobile phone number we received in China starts with +86, indicating that the mobile phone number belongs to a user in China!
