I live in a small North island rural township, which is fortuitously has good internet, but unfortunately variable cellular signal from usable to none both with Spark and Vodafone, depending on weather. My VDSL2 connection with Inspire gives around 55/24 according to speedtest.net.

I run a home business and mainly use my 2talk for calling, but still needed to be able to reliably receive texts and calls to my mobile and make some calls, commonly to cellular numbers, which are cheaper from my mobile.

I bought a Vodafone Sure Signal and plugged it in. After a couple of hours and some confusing error light statuses decided to leave it overnight and call up Vodafone the next day. Sometime after I went to bed, it decided to start working.

What can I say about the service?

It works. The device does what it's supposed to do. The only thing is it's a blackbox which is totally useless geek wise. It doesn't even have a web status page.

But it has made a tangible difference to my calls and texts.
