For example, you could get an Xperia Z3 for £459 (or £20 a month) through giffgaff over 24 months. On top of that, you could get the £15 goodybag (which you can change on a monthly basis). That gives you a brand new phone. 500 mins, unlimited texts, and 3GB data. All for a combined £35 a month.
The closest match on EE would be £43.49 a month (or £203.76 over the lifetime of your contract), and you're tied in to that for 24 months.
Just had a look at Vodafone, they give either:
600 minutes, unlimited texts, 1GB data for £34.50/month
Or Unlimited minutes and texts and 4GB data for £39.50 including Spotify Premium /Sky Sports/Now TV for free (think you choose one, and have it for 6 months)
