Check out the Global Filipino card issued by PNB... it's a debit card
So you can only draw out what's in the account.
Go into the London branch with ID, and they'll basically issue you one there & then.
... send it to the Philippines, and tell her the PIN number via messenger or txt.
Any time you need to send some money, just call PNB and transfer money from
your normal bank account (NatWest, HSBC etc etc)to your PNB Global Filipino account.
Money there (to be drawn from ATM) within 12hrs .... probably quicker.
