Boost your mobile phone’s reception at home
If you have poor mobile phone reception at home then the Vodafone Sure Signal can help. This device connects to your broadband router at home using an Ethernet cable. Once you've registered the phones you want to use with it on Vodafone's website, the Sure Signal then routes calls and text messages to and from your mobiles over your internet connection instead of your mobile connection. Your phones keep their numbers and work as normal. It also works with internet traffic, although there's no point in doing this at home when you have Wifi.
As with previous Sure Signals, it only works with Vodafone pay monthly or pay as you go mobiles. Unlike previous models which were the size of a router, this new version is around the size of a mug and plugs directly into a wall socket. It's still big enough to block adjacent power sockets, but it does have a pass through socket so at least you regain the use of the wall socket it's plugged into. There's also an extra Ethernet socket to compensate for the one used by the Sure Signal on your router.
We tested the Sure Signal in a three storey north London house with poor to middling Vodafone reception. The Sure Signal was positioned on the second floor and proved to be effective at improving reception on the ground and third floors. Calls which would otherwise be missed or dropped mid-conversation were successfully received. Disappointingly call quality didn't improve –voices remained tinny and robotic sounding.
Annoyingly calls made from a Sure Signal-connected phone are still charged at the same rates as if you were using your mobile connection. If you wander out of range of the Sure Signal then your call can drop and you'll need to redial. The Sure Signal should also improve text message reception, but we weren't able to test this.
In our tests the Vodafone Sure Signal was easy to setup and improved mobile reception, but not call quality. At £100, the price can be hard to justify especially if you already have a landline phone at home that can be used instead of a mobile.
