Do I have to change my mobile phone number for Didi?

Yes, Didi's mobile phone number must be my own, real-name registration system.

Didi Dai can change his mobile phone number. Click on your avatar on the driver's side of Didi, and the column of mobile phone number will appear, where you can only change your mobile phone number once a month. Didi's driving must be that I modify my mobile phone number myself.
