As a final update for the PSN cards, here is what I've gathered about the whole PSN cards availability.
DLC and expansion packs for games are usually region-locked, i.e. EU DLC will work only with EU games and so forth. Some of the games are region-free, i.e. EU DLC will work with a US game; however, there is no way you can find out if a game is region-locked or free when it comes to DLC (unless you risk trying it out).
In order to find what region your game is under, check the backbone of the game. The backbone is the area of the case where it doesn't open up, basically the hinge of the case.
There are 3 codes you can find there:
BLAS- ##### is for the Asian region
BLES- ##### is for the European region
BLUS- ##### is for the US region
For each region, there is a specific store you need to download the DLC from.
For games from the Asian region ---> Create a PSN account with Hong Kong as the chosen country. The Hong Kong Playstation Store is in English.
For games from the European region ---> Create a PSN account with UAE as the chosen country.
For games from the US region ---> Create a PSN account with the US as the chosen country.
In the creation process of each of these accounts use the following:
For the address, google any of the hotels and use the same hotel address.
For the sign-in email, use the
qwerty@spam.la (replace the qwerty with anything you want) (the spam.la domain is a free public domain so be aware that whatever will be arriving from the PSN to the the email
qwerty@spam.la will appear to whoever accesses spam.la so DO NOT PUT ANY CREDIT CARD INFO at all in your PSN account)
Now unto to the available PSN cards,
Play-asia.com provides Prepaid PSN cards for both the US and Hong kong accounts for reasonable prices.
Virgin Megastore (in Lebanon) provides Prepaid PSN cards for the UAE store (European region).
Finally, you just have to add funds from your card unto the account you created and you're free to download and install the DLCs, games and expansion packs compatible with your disc-based games. Of course, after putting them on the queue for download, you can return to your original Lebanese account to continue your playthrough of the game (any trophies achieved will be credited to your Lebanese account)
Cheers :D
