Re: are these different from the femto cells Three supply?
They're essentially just the same. Despite usually being called "booster", all they are are a low power mobile mast setup, but only receptive to registered 'phones. They use your modem router to send the signal to the supplier. The advantage of the Voda unit, was that it was of a much higher power. I could get a full power signal up to 30 metres away from the unit, and that through several thick walls. The Three unit by comparison is much less effective, the signal level notable dropping off in the next room. I changed simply because of the incredibly bad customer service. In my entire life, I've never come across such consistently bad service, which applied across the whole of the company.
