Redeeming your O2 Free Sim promo code at the checkout

"Enter code in the checkout" how many times have you seen this on a checkout, and how many times have you then gone off seeking working coupon codes for that store? Isn't it annoying when you think you've cracked it only to see that the code actually expired in 1765? and was actually only valid on the purchase of horseshoes. That won't happen here.

We pride ourselves in making sure the information we show you for O2 Free Sim and the 1000's of other stores we list is always up to date, and correct as of today 26 February 2021. If you find a coupon code we have missed for O2 Free Sim or for other brands please email us.
