If  so, then you can reduce your monthly fee by £15 by simply converting to the Simplicity 20 tariff on Pay As You Go.

At £20 per month for 600 mins + 1200 texts and with unlimited internet, free cloud/open zone wifi and visual voicemail – this is actually a better package than I had on my £35/month (18 month) iPhone contract.  Crucially, this is a one month rolling contract so you are not tied to 02 for another 12/18/24 months.

Also, don’t forget to unlock your iPhone from o2!
