There are two types of acceleration modes, all of which accelerate and only accelerate abroad.
FastLink's default acceleration mode is "accelerate only abroad". This setting only speeds up the network connection outside your country, so that your network speed can be optimized.
When you plan to hide your IP address under any circumstances, turn on global mode and FastLink will speed up any line. But it also raises some issues, and you may not be able to use local payment and social software.
