Hats off to Engadget for a really useful review of the (UK) FreedomPop network - I heard nothing from FreedomPop since I signed up, and quite frankly this free service just won't be good enough for my mobile telephony needs.
Engadget have written a decent review of FreedomPop in the UK, which I advise you to read HERE.
In my case, free doesn't mean that FreedomPop is a network that I'll be using for one main reason:
The reviewer (like many people) uses more data than anything else on his mobile. They noted that call quality on the FreedomPop network is, by the sounds of it, really bad.
Now, I know that most people prefer to email colleagues at work rather than speak to them on the phone, but I do use a lot of minutes every month, and having a less than perfect voice connection just isn't good enough.
I doubt that FreedomPop will be able to do much about this, plus of course they rely on Three's 3G network for all data/voice/text connectivity, which isn't always the most reliable service in some parts of the country.
If I was a very casual mobile user, FreedomPop would be a good choice, especially since the last "free" network to operate (Ovivo) sank without trace in 2014, leaving a gap in the freemium mobile phone market.
I have waited a good few months to see what FreedomPop were going to be offering in the UK, but unfortunately I feel that I would be disappointed having read this review and other people's opinions elsewhere.
