Special calls are the most commonly used charging APP for car owners at present, because the special calls enter the market earlier, so they can find their charging stations in the first and second tier cities in the country, some charging stations or special calls operate their own, more favorable charging costs. Of course, due to the early construction of special calls, many charging piles do not support fast charging at present, and the facilities in the station are relatively old. So if you want to use a fast charge, it's best to find some newer charging stations. Overall, the special phone is a good charging APP.
