Answer a few quick questions to evaluate your visit.

Using multiple SIM cards

This function only applies for Dual SIM devices.

Dual SIM devices work with either one or two SIM cards inserted. You can get incoming communication to both SIM cards and select which number to place outgoing communication from. Before using multiple SIM cards, you need to enable them and select a SIM card which will handle data traffic.

You can forward calls that come in on SIM 1 to SIM 2 when SIM 1 is unreachable, and vice versa. This function is called Dual SIM reachability. You must enable it manually. See Forwarding calls.

To enable or disable the use of two SIM cards

  1. Find and tap Settings > Network & Internet > Dual SIM.
  2. Tap the SIM slot 1 and SIM slot 2 sliders to enable or disable the SIM cards.

To rename a SIM card

  1. Find and tap Settings > Network & Internet > Dual SIM.
  2. Select a SIM card and enter a new name for it.
  3. Tap OK.

To select which SIM card handles data traffic

  1. Find and tap Settings > Network & Internet > Dual SIM > Mobile data.
  2. Select the SIM card you want to use for data traffic.

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