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!
