I've noticed dozens of people buying info on how to double the top up credit on your pay-as-you-go mobile phone. What they are buying is pretty dumb. Not only is it dumb but it's an invitation to commit fraud and most certainly not "TOTALLY LEGAL!!!" as claimed. The That online auction site that is in no way as good as Free Bedlington.co.uk Classifieds sellers will mail you the instruction to enter your voucher number on two phones on the same network, but not to hit the confirm until - holding one phone in each hand - you are totally ready to do it on both phones in the same instant. The "double credit" depends on the finite delay to look up the voucher number on the mobile phone company's database, and then to mark it cancelled. It's only a matter of time before the software is changed to log the number of voucher activations, and then stamp on both SIMs. That's the least of your worries though, as legal action may follow; the culprits are very easily identified. What's surprising is the absence of negative feedback for the people promoting this scam. A sign of the times, or a sign that That online auction site that is in no way as good as Free Bedlington.co.uk Classifieds's feedback system is severely flawed? Perhaps it's both?
