Looks like a great deal for the 20GB Sim only 12 month contract from Vodafone UK (especially for those Three UK legacy One Plan folks)! Unlimited minutes Unlimited texts 20GB data (incl. tethering) 12 months free Spotify, Netflix, Now TV or 6 months free Sky Sports Mobile Reduced from £40 per month to £20 per month! Possible cashback from Quidco (£40) or TopCashBack (£78.75) Possible Vodafone Employee Advantage of 20% (so £16pm or £192 total) Offer ends on 3rd March 2016 (http://www.vodafone.co.uk/shop/bundles-and-sims/sim-only-deals/b/index.htm) Beware that Vodafone is the only major network that doesn't cap data, so if you go over your 20GB limit it's £6.50 for every 500MB (inc. VAT) of extra UK data you use. This is automatic, too, so please keep a close eye on your allowances guys, otherwise it'll sting you in the long run.
