Need Americans help, Make some $$ :)

Hey all, this is gonna be quite a long post to explain whats going on. I basically
need some help from someone in America.
Im from london(UK) and i need help for a game called maplestory.
Its american only so to play it i use software for IP etc.
But id like to purchase some NX(nexon credit) in the game.

Because my account is freshly made, i cant use paypal or debit to charge it and the only other option i have os to pay with mobile. But it only accepts american phone numbers. I cant get a store card cause they dont sell them here in the UK. so what i need help with is for someone to recieve the text to verify the order and give me the number.

Im looking to buy $15 = 15k NX
and for helping me out ill send u an extra $5 through paypal. So ud have to actually be able to get charged on ure mobile.
Id pay you $20 so $5 profit for helping me out.

Cheers in advance.
