Get a Nokia 1616 phone and pay only £4.99 postage on the Virgin Mobile Simply 8p Tariff. Available to Existing Virgin Media customers only.
This is not the most sophisticated phone in the world, but unless you are a mobile phone junkie this doesn't really matter, because a phone is for making phone calls, and this is what this model does.
You pay £20 and the phone comes with £20 credit, so effectively don't pay for the phone - this information is for those who scan posts just to try and find fault with them.
The Simply 8p Tariff costs (would you believe) 8p per minute and text in the UK, which is cheaper than Virgin land line calls. 50 mins per month free calls between other Virgin mobiles, so useful for your family. You can also call this phone free from a Virgin land line.
If the link doesn't work, you will find this very difficult to find on the site, so may have to phone Virgin to get the deal.
