Im currently on Three pay as you go, and I pay £10 for 10GB data, and unlimited texts and calls. It used to be 4GB but they have upgraded since. I’m not a big data user when out anyway, so it’s pretty pointless these days.
The reason why I’m still with them was mainly because of roaming in and outside of the EU. I used to travel to the US and EU quite often so that made sense. Not so much these days, Maybe I should look elsewhere, so thanks for the recommendations chaps!
