Used to be on Three but gave them up as too many not spots. I got a free PAYG SIM from each of the big four and tested them out where I needed data. Unfortunately the answer for me was EE. They're the dearest but their coverage is best. They don't seem to allow other operators to use their network. Best deal I could find was via U Switch.
