SMS Question in ShellShock live 2

Hello, I do believe it's possible to purchase tank coins through mobile phones. What you do is click ''Earn'' not ''Buy'' after doing so you, if you have something that blocks pops ups please turn that off if not the next step is you should see a second window pop up. In that window you should see multiple options to choose from to buy Tank Coins. Once you do that simply look for a symbol of what look like a cellphone, click on that and you should be able to purchase Tank Coins after that. If you still can't then sorry but that is all i can provide to my knowledge to you.
