How to get codes for your purchase.
Send a text message to 78889 and in that message you need to write "AP" in order for this to work. Once done correctly you will receive a text message back with a code in it. Each mod has a price in codes and you get 1 code for each text message you send.
Example:
To: 78889
Message: AP
