Turn Mobile Data On or Off auf Realme
Mobile data is the switch that lets your Realme phone use the cellular network for internet access when Wi-Fi is not available. Turning it off does not affect calls or texts, but it disconnects every app from the internet unless Wi-Fi picks up the connection.
You control this setting in two places. The quick panel toggle in the status bar is the fast option for daily use, while the full setting sits deeper in the system menu and gives you additional options like data usage warnings.
To reach the main switch, go to Tap on Settings ➔ Tap on SIM card & mobile data ➔ Enable or disable Mobile Data. This is also the place to check if you have a dual-SIM setup, since mobile data can only be active on one SIM slot at a time.
If the toggle looks enabled but apps still show no connection, the SIM slot assigned to mobile data may not match the SIM you expect. Switching it off and on again in this menu often resolves a stuck connection after the phone loses signal or switches networks.
Leave mobile data off if you rely only on Wi-Fi and want to avoid unexpected data charges while traveling. Turn it back on whenever you need internet access outside a Wi-Fi network.
