Selecting a SIM card for data traffic

This function only applies for Dual SIM devices.

If you are using a Dual SIM device, you can select which SIM card handles data at any given time. You can do this during the initial setup of your device, or you can select or change it later via the Settings menu.

To change the SIM card used for data traffic

  1. Find and tap Settings > Network & Internet > SIM cards > Mobile data.
  2. Select a SIM card.

For higher data speeds, select the SIM card that supports the fastest cellular network, for example, 4G.
