How to send a text message to the rider for the US group takeaway?

No texting. Because we want to protect the privacy of riders. Specifically, the Meituan system has a number protection function to strictly protect the contact information of riders. You can only contact the rider by phone, and you can't send information by SMS. This is done to protect the privacy and safety of riders and prevent personal information from being abused or harassed. At the same time, it also avoids information transmission errors or misunderstandings when contacting riders, and improves the efficiency and accuracy of communication. Therefore, when using the US group to take out food, it is recommended to contact the rider through official channels and respect the privacy and rights of the rider.
