The One Plan
Am a three customer and upgraded last year to a new phone. Happily accepted the blurb that my package wouldn't change and unlimited means unlimited.
Unless that is I want to tether for the two weeks I take the family on holiday. Is surprising how much data the kids can use on YouTube.
Not overly bothered about being lied to as I got a new shiny and there are ways around the tethering cap, if you feel so inclined.
