You buy the 'phone at that price from Argos ~ it comes preloaded for Vodaphone Pay as You Go. All you need to do is activate it and buy some airtime. Then you are ready to receive calls and if necessary make some.
You may find it worthwhile, if you are likely to drop it in the swamp or something and thus have to buy another phone which would mean that people trying to contact the published number would get no response, to buy yourself a number that can be diverted to any phone. I have one for my mobile so that if I change phones I simply have to redirect to the new number. nobody knows this is happening and it does not cost them anymore. they are simply paying whatever their provider charges for a call to a mobile. I can also divert calls to my home number and nobody is any the wiser 'cept me and I don't have to give out my home number to anyone. Some people call them "Tracker Numbers" others refer to them as "Personal Numbers". Works for me. Low set up costs (mine cost a tenner several years ago) and no ongoing charges.
