I've checked this and double checked it so it looks kosher!

12 Month Sim Only - £15 Tariff - £105.00 cashback with topcashback

12 month contract,

£15 per month

600 minutes

unlimited vodafone to vodafone calls (online special deal)

Unlimited texts

from here:

So total charge for 12 months is £15 x 12 = £180

less £105 TCB = £75

£75/12 = £6.25 per month!

I think the catch is there are some steep costs if you exceed the 600 minutes like 40p per minute call charges to other mobiles etc

Also, there are crazy prices on mobile internet but let's face it, using this as a back up phone is just for calls and texts! And Vodafone are a pretty good network in terms of coverage.
