Uploaded Game works on active cell phone but not Wi-FI only devices

Hi everyone. Got these strange problem once I uploaded a game to Google Play with set up In app purchases, Leaderboard and ad banners all working. I notice that it works grate on active cell phones but on devices without cell phone connection only Wi-Fi the game dosen’t work properly. I know that some one might download the game just trough Wi-Fi and won’t be able to see the score text and leaderboard achievements. Unless you got an actual active cell phone. Does any know how to fix these God forbidden problem. Thank’s a 3million!!
