Will visible be throttled? I do have surfshark vpn can i use that?

Hard to say as Visible has changed recently. However, you can change the Cudy imei to match the one on your phone and change the TTL/HL to whatever works for Visible. AT&T works better in my area so I haven't tried my Visible SIM in it.

Where can I get a manual for this, not the setup one in the box?

You can download from their web site but I recommend you give these guys a call. They will load you up with great advice and info. They didn't sell me anything as a matter of a fact they gave me the info for their stuff and competitors. With that knowledge I made my choices and glad I did.

Need to find the best sim data plan for this device? i am trying to find my best least expensive option for unlimited data? maybe visible? please help

The only unlimited SIM plan that we know of is US Cellular. They have limited coverage in the USA.
