I have to test the performance of picture uploading from USA without using a VPN on WEB and on iOS device. Will be good if at least I could sent a request from to USA. Is it possible ? There is any app which can help me?
I try BrowserStack but it's not what I expect,
If you would like to upload something without a VPN established, you could -
Get a VPS in the region you would like to test (the US in your case), then connect over a remote desktop, it could be either RDP or VNC. With that, you could open a browser in the VPS and do everything you want just like a local machine.
But this is only for Web case.
