Hi Matthew,

There isn't at present; while Three will issue the box to consumers they will not yet issue them to businesses. You could call up Business and make your case, but the limitation could well be technical at this time.

Annoying me too. I actually have sufficient coverage at the office, but I need a box for home - otherwise Three is useless for me. Fine for the iPad where it's data-only and WiFi is adequate if not preferable, but no good where voice is required.
