let me see...I'm not really being fair to O2 in relation to etc etc....see previous post....because you are given the option to 'cap' as in cut-off-once-you-have-used-up-your-monthly-data-quotient.....which I was to opt for...rather than that 'unofficial overdraft' scenario....additionally, the first time that I was to visit O2...staff were to tell me - that the operators could fine you £5..."but normally they don't - it's just a small charge" for going over - regarding how much you have used over and above etc etc....hmmm...the whole thing reminds me of that 'bank letter' scam - see previous notes upon Lloyds bank...the Ipswich branch...sending me so many letters pretty much  'in one go'...each costing me £20...I had to pay £80 in the end and all because of going into the red - by just a few pence...anyway, looks like internet companies might go the same way as the banks - if they etc etc...i.e. have to pay back quite a bit, if they get too greedy and I suppose that they are probably well-aware of that one and so are 'reining it in' so to speak....go figure:
