Pick Up The iPhone 5C From O2 For ?50
O2 is one of the first UK carriers to reveal its prices for the iPhone 5C putting it on sale at only ?50.
O2 are offering the iPhone 5C with unlimited texts, 600 minutes & 750MB 3G data for ?32 a month. If you are after 4G the upfront cost will rise to ?99 and a monthly cost of ?42 and that will get you unlimited texts, unlimited minutes & 5GB 4G data.
You will be able to pick both the iPhone 5C and the iPhone 5S up from O2’s stores on September 20th but if you do not fancy lining up outside the store then the iPhone 5C will be available to pre-order from tomorrow.
