Vodafone UK announced a raft of new SIM-only plans for the cost-conscious consumer today. The deals, spotted fresh on Vodafone’s site today, offer the choice between 30-day or 12-month price plans, both of which offer unlimited data to those hunting for a better SIM deal for their existing phone.

The 30-day SIM-only plans cram in 600 minutes anytime, unlimited texts and unlimited data for £20 or chatterboxes can bump this up to 900 minutes anytime, unlimited texts and unlimited data for 25 notes.

If you sign up for 12 months’ SIM-only, then you can see the same 900 anytime minutes, unlimited texts and unlimited data price fall to £20, while a whopping 1200 minutes anytime, unlimited texts, unlimited data and unlimited UK landlines will set you back £25.

Each deal means that you can do as much Facebook foraging, Twitter tapping or MySpace mooching as you can shake a SIM-free phone at, subject to a 500MB fair usage policy, natch.
