Been with Meteor for the last couple of years and find their tariffs very good. Especially the "talk & text for free to anyone on the same network" if you spend €50 on the monthly plan.
Website is pretty good but the webmail is rubbish. I had created a new account when I signed up to Meteor and within a couple of months, it was full of spam, without me even once using it to sign up to anything.
Samsung phones are really nice looking, but I think they still have flaws with the software compared to SE (who I think have the best software). I had a G600 that I couldn't grow to like and went back to my old W810i.
Horses for courses.
