First of all, sorry for my terrible english, is not my native language.
I have bought a prepaid card in a store, but every time I try to enter the code in my 3DS, I keep getting this Error Code: 005-5838.
I have searched this error but in the support page it says that the 3DS can't connect to the internet, but I'm already connected in the eshop, so I guess is not the correct information.
Additional to the Error Code I get this on the screen:
" The activation number could not be recognized.
Please check the number again and try entering it again."
What do I have to do?
