Enable or Disable Mobile Data Warning auf OnePlus
The data warning on OnePlus phones is a threshold you set inside the billing cycle settings for mobile data. Once your usage crosses that number, the system sends a notification, but it does not block your connection. That distinction matters: a warning only informs you, while a separate data limit actually cuts mobile data off.
This function sits inside the same menu as your billing cycle date, so it only tracks mobile data, not Wi-Fi traffic. If your carrier resets your cycle on a different day than what OnePlus assumes, the percentage shown next to the warning will be inaccurate until you correct the cycle start date first.
Where to find the setting
Open Settings ➔ Wi-Fi & network ➔ Data usage ➔ Billing cycle ➔ enable or disable Set data warning. From the same screen you can adjust the exact data amount that triggers the alert.
Turn the toggle off if you rely on an unlimited plan and the repeated notifications feel unnecessary. Turn it on if you are on a capped plan and want a buffer before you hit the limit, especially if you also enabled a separate data limit that cuts off mobile data automatically.
If your data usage numbers still look wrong after adjusting this, check that the billing cycle start date on the same screen matches the reset day your carrier actually uses.
