Three.co.uk Home Signal box not working

[Vatreni]

Couldn't find a forum dedicated to 3, so hopefully someone can advise here.

I have been sent a Home Signal box from 3 as indoor signal is non-existent. I have a couple of queries:

It just flashes green constantly which according to the poor documentation here http://support.three.co.uk/SRVS/CGI...et_pid=6908,varset_cid=6910,Case=EXT(EM99485)
says it's connecting to their network. The document says this can take an hour but it's about 18 hours now. Have reset and turned it off/on this morning to no avail. It's connected to a switch that connects to the router upstairs, but it has picked up an IP address so no reason it has to be directly into the router. Any ideas why it won't bind to 3's network?

The other thing is that the instructions here http://support.three.co.uk/SRVS/CGI...et_pid=7648,varset_cid=7649,Case=EXT(EM99445)
don't mention the special green SIM card that comes with the device despite showing the slot. When there's no SIM card in, it flashes red so obviously needs the card. Is the way this box works that the SIM card in the Home Signal in effect creates an internal phone network that my phone registers on, then this then connects to 3's network through the ethernet/broadband? Like a mini-mast?

thanks

That's the only way it could work. Three also offer WiFi calling, here's the link: http://www.three.co.uk/discover/three_intouch. I'm on three, but I get a good 4G signal, so I've never needed to even think about WiFi calling or a Home Signal box.
