What our customers say

Hi Graham, the SIM has worked really well at places I usually get zero connectivity. Today I walked the dogs to my local. It’s a black spot for 4G but I managed a connection.

I've also had it to a couple of fishing marks where I get no signal and got better download speeds than my hard wired connection at home.

From Scotland

I'm so happy I can actually function from one space, it's a big relief from a daily frustration!!

For anyone that lives in the country internet is usually a nightmare and I was so fed up with it. Don't ask me the tech details of how it works but it does!

Great result! Connected phone, ipad and tv to the router. Streamed live tv programmes and youtube music with no problems from buffering. Fantastic product!
