In the past I have always looked for the HSBC ATM *because they were the only ones that let me withdraw 20, 000 per a transaction. On last months trip I tried just about every other banks ATM and the most I could withdraw was 10, 000. Most of the ATMs stated "your bank will not allow that amount of a withdraw" (not the exact wording, but you get the idea). But for some reason my bank, Wells Fargo, trusts me to withdraw 15, 000 from HSBC*
Still prefer the good ole days when they offered 20, 000, but I had no other choice. *The only HSBC I found was the one mentioned below, across the street from the terraces of Ayala mall in Cebu.
Also as noted below, my iPhone and iPad both convert I'd into I'd. It's an Apple thing.
