Whoooo (so far)!
Site was simple to use and I quickly found a great sim only contract at a really reasonable rate: 1GB data (no 3G where I live so no need for more), 1000 minutes & unlimited texts @ only £15 per month.
Purchase tracked super fast - all terms and conditions of purchase were met - let's see if my £45 cashback actually gets confirmed! Not had a lot of luck lately, cashback over a quid or so keeps getting declined, yet all 36 pence or so transactions get confirmed. Will update review with whatever happens!
