This Samsung Galaxy S II offering from Phones 4u used to demand £150 up front, but it’s currently free as part of the retailer’s January Sale. Sah-weet. At £21.50PM over 24 months, you’re looking at £516 over the course of the contract.
For your monthly £21.50, you get an O2 allowance of 200 minutes, 3,000 texts and 500MB of data. That'd do me.
