The mobile data cycle (Settings -> Data usage) looks quite arbitrary. Since I have changed my data plan, now the new cycle should start at the first day of the month instead of the 6th.

How can I change the begin of a data cycle? I cannot seem to find some edit button, though I vaguely remember seeing it at the Data usage cycle menu.

Affected versions: Android 4.0, 4.2.2, 4.3.1.

Changing the starting day for Mobile data is indeed non-obvious. You need to enable the mobile data connection (2G/3G) before the options are available:


  1. Enable Mobile data.
  2. Exit the Data usage settings app.
  3. Tap the spinner below the Set mobile data limit checkbox.
  4. Tap Change cycle....
  5. Change Date of each month (I prefer the first day of the month, 1)
  6. Hit Set.
  7. Undo Mobile data if necessary (e.g. if on Wi-Fi).

    The option Change cycle may appear after selecting the set mobile data limit in the dropdown with dates.

    Even in Android 6.0, you have to turn on mobile data before you see the option to change the cycle.

  • @Pacerier It probably applied to Android 4.x (see question). The "spinner" referred to a "drop down" menu where you could select the time range (and the Change cycle option). With Android 8.1 (Pixel 2), there is a Billing cycle option within the Data usage menu (which is visible, independent of whether mobile data is enabled or not).

For me (CM 12.1), it is still confusing. You have to go under Settings, Data Usage and then:

  1. make sure that both Data connection and Set mobile data limit toggles are ON
  2. below them, there is range of dates dropdown, which you can choose to see data usage of previous months. Click on it, and you will get a list of previous periods.
  3. now, you have to scroll all the way down through all periods (mine seems to go back all the way down to January 1970 !!!) - below the last one there will be Change cycle... option. Click it, and it will allow to change starting date.

I ' ve got it - Go to Settings -> Data Usage -> Tap Mobile and them, on the 3 dots at upper corner, chose Disable all appls. -> Tap WLAN and do the same, disable all appls -> Restart phone -> After entering your PW (if any) a display is shown warning about your data usage limit, saying it is paused. them gives you 2 options RESUME or OK -> Tap RESUME . That's it ! you are back on the road to setup a new cycle.
