It sounds like your network provider is not giving you good enough data speeds to handle the game … I have had this issue when traveling in regional areas for work, the quality of local services is such that I can often only log in and play very early in the morning or very late at night when there is not much traffic on the local provider network.
You can find troubleshooting here, but if everything works fine on your wifi, but not on your mobile network, then I would suggest you need to check with your network provider .
