The £100 quidco is back on O2 12 month SIM only plans. This means you get 1600 texts, 800 cross network minutes and 1 free bolt on for £11.24 a month after cashback if you take out the £19.58 a month plan.
Or for heavier users you can get 3200 texts, 1600 cross network minutes and 1 free bolt on for £21.04 a month.

Unlimited O2 to O2 Calls
Unlimited Web Bolt On
Unlimited Weekend Calls

200 Extra Anytime Minutes
You can only choose one add on and can only change it once every 3 months.
Both on 12 month contracts.
I got the lower bundle last time this offer was on and quidco tracked at £100. Combine this deal with a cheap pay as you go phone and it's dirt cheap calls, texts and web browsing.
