I need to use proxy on my IOS phone farm

Hi,

As I wrote on the title, I need to use proxy on all my phones but I never used proxy on mobile. Is there any way for me to control their proxies at one pc, and are there any guide on this maybe? I'm currently searching on web & BHW but if there are any guides that you know, please link me on this thread, or you can reach me on pm.

Thanks in advance.
