can i earn from mobile?

You can earn, but you cant see your name on the scoreboard, thats all 

You can work at stations when you're on mobile (It's allowed!!) but you might have problems when you're claiming your reward, such as not being able to view the scoreboard and check whether it's full or not. However, a solution to this 'problem' is that you can get your friends who are in base and using a laptop to check it for you :-) before sitting on the chair to claim the reward!! Cheers, x
