What is the mode of sending mobile phones by SF Express?

1, divided into land transportation and air transportation.

2. Ideally, SF's aviation parts can guarantee that the whole country will arrive the next day. SF's delivery logic is that under normal circumstances, if there are two or more modes of transportation, SF's first choice is air. If land transportation is selected, the land transportation price is the first weight of aviation -4+ continued weight of aviation parts /2. The time limit for land transportation of parts is air parts+1 to 2 working days. There is also a misunderstanding that express mail without aviation parts can only be transported by land. Land transportation can be roughly divided into two types: automobile transportation and railway transportation. Electronic products, powdered liquids and other express mail that can't pass the aviation security check can't pass the railway security check. At this time, we can only transport by car.
