I'm from the Philippines and I'm using a North American 3DS. I would like to buy my own Pokebank pass, but the eShop keeps on getting an error when I try to purchase it using my MasterCard. I don't know about USA ZIP codes so I just used one I found on the internet. Even then, I kept on getting error 026 - 7511 with the message "This credit card can not be used" or something like that. I tried adding $10 to my funds using the eShop but I got error 011 - 7511 instead.
I looked around on the internet and I found out that these two errors mean that I'm not connected to the internet. I don't understand why because I was sitting right next to my router when I tried to purchase from the eShop. Furthermore, the error message said that "The credit card can not be used" so I believe it's a problem with the credit card and not with the internet. Any ideas on what I could do?
