Answer 1

Open the Settings app on your phone .
    1. This is your phone's Settings, not the Settings in your Project Fi app.
    2. Under "Wireless & networks," touch Data usage.
    3. Next to Set cellular data limit, move the switch to the On position.
    4.Read the message in the box that opens, and touch OK.
    5.Touch the date range and set the date to match your billing cycle.
    Tip: To see your billing cycle, just open the Project Fi app or website and go to the Account tab. You'll see the date under "Current cycle."
    6.You’ll see a data usage graph with a line at the top that says “limit.” Use the bubble on the right side of the graph to drag this line to the limit you'd like to use.
    7.That's it. When your data usage reaches this level, mobile data on your device will turn off automatically and you'll get a notification.

如果你达到了你的限制，但又想重新打开数据，方法如下:

1.Open the Settings app on your phone .
2.Under "Wireless & networks," touch Data usage.
3.Next to Set cellular data, move the switch to the On position.
