I think most folk on here would call me 'helpful' for supplying this place for FREE and putting in hours,weeks,month,years....of work for plonkers like you!
With anti-fraud devices in place on many cards these days, you need to have the bank UNLOCK it for use in the Philipines, before leaving the UK, otherwise it will not work. This goes for most folk travelling, whatever the card, as the banks may put a stop on it even if you've been using it a few days.
A simple phone call to the bank before leaving is the easiest way to ensure any bank card will work when abroad.
