Don't know about Peak specifically, but I've been on Orange/EE for years and have usually had a decent signal in most of the rural parts of Cumbria. I've generally found their customer service to be good, I rang up to pay a bill last month and they dropped my tariff by £10 per month, and upped my data to 2.7gb per month from 1gb. So I now get unlimited calls, unlimited texts and 2.7gb of data a month for £21. Fairly happy with that, but on the downside they now charge you to call customer services out of hours, I was late paying my bill this month so they sent me a text that was very matter of fact and stated they had charged me £5, and they have had that recently publicised stunt of allowing customers to pay to jump the cue when calling up for assistance. I have my ipad on EE 4G and it is well rapid also.
