The part about them reserving money against your credit card makes little sense as I've used Mobal with a pre-paid credit card plenty of times before.

Also, is there any reason the Mobal rates are so much higher than standard O2 UK rates? 80 US cents per SMS is very high & so is 14 cents per 10 kilobyte (14 $/MB). Do they charge this much just because they can (like all data & SMS roaming charges are) or is something else at play here?
