I dropped my mobile phone, and all the important information in it was gone. Can I have them back?

If your short message is not backed up to a computer or other storage device, it is basically impossible to find it. SMS only passes through the operator (mobile company), but SMS movement is kept confidential as personal privacy, and it is also very strict unless there are special treatments, such as police checking criminal records. If you know someone, maybe I can help you, but the chance is slim. Everything that is important at ordinary times should be backed up and kept in the computer. It's useless to lose your mobile phone number. If you steal a mobile phone, you lose your phone card.
