Mine tracked in about 10 minutes, but I doubt they'll pay up... still worth a punt!


Of all cashback sites I like Checkoutsmart the best. Albeit only food offers.


Appreciate what you are saying but why ‘punish’ OP who is posting with all the good intention. Surely deserves the heat for the effort.


Quidco didn't track for me, but Quidco were happy to raise a claim. Had to send copy of top up voucher and O2 email. No cashback as yet though.


Thats possibly because they have done similar Quidcon offers and recieved zero dimes back. Are you voting on the thought of getting paid or actually getting paid.. big difference.. Like buying a lottery ticket.. you have a chance to win..

Quidco offering £5 for ordering a free O2 sim.
Not sure if this is a freebie or a deal? Either way it seems a bit of a no brainer, a free fiver just for ordering a free sim card!

1 arm 1 leg 1 first born.




Even after top up my Quidco never paid those £5


you have to top up to activate


Ta must tell MSK was complaining about the lack of points X)

Much better deal Use quidco and get £20 or £30 free credit https://www.hotukdeals.com/deals/possible-free-30-o2-pay-go-sim-10-top-up-required-2181487


A bit like posting 'Free search engine called Google' or 'Free unlimited air for anyone to use'.


Hot from me. I bet not everybody knows


Everyone knows about this already though, and all the networks do it.


Shouldn't get so cold as these sims are about £1 from high street shops.

It was always going to be dodgy, I don't know why anyone thought it wouldnt be.



Quite a few people seem to want it to end by the amount of unnecessary posts, arguing, cryptic comments/replies, and questions about how it could be used in other ways. And to save someone making an unnecessary post to point out this is an unnecessary post, yes, this is an unnecessary post.


100% my thoughts too


Milkshake you seem to want this offer to end just so you can say “I told you so”. Every time I see a post from you I know it’s going to be eye rolling time.

I chose the £15 bundle sim personally, then topped up just £10 and my credit wasnt converted to any bundle, it was a credit of £10. Maybe thats a good way to go about it actually. When your sim arrives, dont top it up yet, wait for the email two weeks after it arrives that tell you to top up and get £20 free. You will have a balance of £30. You can pay £25 into your PSN account, and have about £4.80 left over after the cost of the confirmation text.


Confuse here, hope someone can help. Which sim card did I choose? All I see is bundle sim and its says "Top up and we'll instantly exchange your credit for a set allowance of minutes, texts and data that's valid for 1 month." So does that mean when I recieved the email for extra £20 credit with £10 top up I end up with £20 for PSN since £10 went to the bundle? And do I need to activate sim when sim arrives or sametime £20 email sent?


I can confirm it works just fine. I topped up my PSN account with £25. Obviously the text cost means you cant do the full £30.


They emailed me

02 never pay out on quidco


Fair enough, but if you can't or want to get a contract then I think this deal is fairly good. £15 equal to 60 minutes of calls, I know not much but if you don't want the contract (for example for your kids) then this could useful.


sorry but I voted cold as I was just looking for deals on blackberry and decided to go with the tesco pay monthly capped deal. £12.50 per month for 500mins 5000 texts 1gb of data as well as your bbm stuff on a 12 month sim only deal. Think it was £15.00 pm for a shorter deal.

Pakistan is now 7 p :)


I recently saw a ad somewhere which said .5p to India, and few other countries... 5 pounds - 1000 international minutes on O2. Any comments on that ?


terms and conditions, http://www.o2.co.uk/termsandconditions/tariffsandboltons bit confusing as they indicate min 10 topup to continue getting free o2 calls and text but nothing about stopping international tariff


Needs expired as confirmed with O2 a £10 top-up needed to switch even though i have £22 credit on my phone.


Can you point me in the direction of this 0.5p for the US please. I regularly ring from a mobile to the US and 2p is a penny cheaper than I currently use. I would love to use the company that you use if it's 0.5p Cheers :D
