When I brought passengers from Ho Chi Minh City to Binh Thuan, my car had a tire failure. But fortunately I knew about the eCA application before that. Almost 2 minutes after I pressed for help, several people including auto repair shops and other drivers received my “call for help”. Less than 10 minutes later, a driver showed up and helped me change a tire. , then I sent him a gift bought on the eCA app at a very cheap price.
