Just bought an EE Sgnal Box. They had no issues selling me one, despite being in a high signal area, once I told them I get no signal on the ground floor. Cost me £95 delivered and worth every penny. No longer do I need to leave the phone on the top floor of a 3 story house in order to receive calls. It’s Nokia kit and excellent quality. If you have an iPhone it plays a high-low-high tone through the earpiece when it switches to the Femtocell.
Notes:
It’s supplied in open mode and won’t be locked down to your choice of users until September (possibly never). If you have close neighbours you’ll provide a signal for them too, routed over your network. In theory, since they’ll be connected via a VPN you’ll be protected from anything dodgy they decide to do on the 3G signal.
Said neighbours likely to be moderately pissed off when their excellent signal disappears in six months time.
You shouldn’t place it right next to your wireless router due to interference issues (2.1GHz vs 2.4GHz). It comes with a loooooooooonnnnnnnnnnnnng network cable if you haven’t got your own wiring, or you could use a power line adapter.
Orange are less enthusiastic than T Mobile at sending them out, but you could just register a business account which entitles you to one straight away. Signal Boost on the mobile works ok but isn’t brilliant, limited compatibility, and no support for other people if they need to make a call.
