Leaving aside several “are but’s”, yes PDA’s are not much more than clever mobiles and they can be used on virtually any network. Their cost is usually made up from two things. (A) The cost of the device and (B) the cost of the airtime used.
We’ve not quite reached the point yet where they give you a free PDA when you fill up at Asda but it’s getting there. Depending on what you want, new or second-hand, you can pay anything from £50 to £450 for a PDA. Most companies choose to buy a contract (normally 24 months) and this gets you the PDA and the airtime bundled together for about £3/week. At the end of the two years, the PDA’s yours (they never ask for them back) so you can then either just have an airtime only deal or put the device on Ebay, get some cash and start a new contract with a more up to date device. Buying off Ebay you could end up paying say £70 for a reasonable device. Then get an airtime deal that gives something like 1 gig of data or 12 months (whichever comes first) for about £20 a year. So over two years that works out at just £1/week.
Your going to have to work it out yourself from this what it costs to send each job out but the average maybe would be about 0.5p (or 0.6p if we throw in some text back).
Will it ever be free? Not as long as we have BT and Vodafone shareholders all wanting profits.
