## Questions & Answers

**Q: Will visible be throttled? I do have surfshark vpn can i use that?**
A: 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.

**Q: What type of connectors does it use for the 4g lte antennas?**
A: SMA

**Q: Where can I get a manual for this, not the setup one in the box?**
A: 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.

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