Realme: Set a Monthly Mobile Data Limit

Realme UI includes its own data counter, separate from the one used by your mobile carrier for billing. Small differences between the two come from timing, background sync, and how each side rounds usage. A monthly data limit on the phone gives you a self-managed ceiling that resets automatically, so you get warned before your plan runs out rather than after.

To set it up, open Settings ➔ SIM card & mobile data ➔ Data usage ➔ Mobile data limit. Enable Set monthly data limit, then tap Data limit to enter the amount your plan allows. Confirm with Save to activate the tracking.

The limit only affects mobile data, not Wi-Fi traffic, and it does not automatically cut your connection once the value is reached. Instead, Realme UI shows a warning notification so you can throttle background usage manually. If you need the phone to actually restrict data at the limit, check whether your carrier offers a hard cap through its own app, since Realme UI is built for monitoring rather than enforcement.
