Please be nice - this is my first post!
This deal is only applicable for o2 existing customers coming towards the end of their current contract.
I called O2 and asked to be put to the Cancellation team (they offer better deals then the Retention team). Call 202 from your mobile or the direct team free tel no: 0800 028 8151
They asked the reason for me cancelling - I said I have another sim with '3' and they have offered me a good tariff for £15.
They then offered me the Online 25 tariff - with a £15 discount each month for the duration of the 18 month contract.
Meaning you get all the below for only £10 per month!
Free Mobile Phone: Limited selection or pay extra for phone you want - (I got the Samsung U800 free - nice slim phone, in brushed stainless steel)
200 UK minutes
400 UK texts each month
Plus unlimited O2 to O2 calls
Browse the internet on your mobile for up to £1 per day
Free itemised online billing
The Online 25 tariff is still advertised on their website - so you can try your luck if you want a great deal - with a low monthly outgoing - I don't think I will ever go over £10 on my bill as most of my friends/family are on O2 - so I will be taking full advantage of the Unlimited calls!
The best thing is - if you decide this tariff or the free phone is not for you - then you have a 14 day cooling off period.
