Samsung How to Turn On/Off Data usage limit

If the Data Usage Limit on the Samsung device is reached, the data limit switches off the mobile data for the billing cycle, and the mobile data is reactivated in the new cycle (by default the 1st of the month).

Note: The calculation of the data volume on the Samsung device may differ from that of the mobile phone provider, so it is advisable to set the data limit slightly lower than the actual data volume.
