Q: I am trying to register a drone through the "Suishenban" app. I have completed real-name verification using my passport. However, when submitting the drone information, an error occurred because I used an international phone number, which exceeded the field's character limit. What should I do? 

A: At present, the drone registration and flight filing system only supports domestic mobile phone numbers. International numbers cannot be used.
