Saying that its a fact that Three is a terrible network.
I’d beg to differ. I use my 3 phone in the house tethering the 3G signal, which way exceeds (10-14Mb/s) the BT broadband. I’ve just returned from a filming tour of the UK and, apart from poor internet speeds in Nottingham center, my network was almost always excellent. The three other guys were on EE 4G, O2 and Vodafone – all three were constantly moaning about their lack of connection, especially the Vodafone which seemed to be unable to make it out of the ‘E’ coverage for the whole trip.
As far as 3’s customer service goes, my limited experiences have only ever been satisfactory. I also received a token refund when they had local mast issues for a few days. I’m sure that other people have had trouble with the company/network, but my service from them both here and in Ireland has been consistently good.
