Using a Dual SIM device

A Dual SIM device enables you to do the following:

  • Receive incoming communications via both SIM cards.
  • Select the number from which to send outgoing communications, or have the option to select a SIM card each time you place a call.
  • Forward calls received via 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.

Before using multiple SIM cards, you need to enable them and select a SIM card which will handle data traffic.

Hint

  • A Dual SIM device works with either one or two SIM cards inserted.

Enabling or disabling the use of two SIM cards

  1. Find and tap [Settings] > [Network & internet] > [Mobile network].
  2. Select a SIM card.
  3. Tap the [Use SIM] switch to enable or disable the SIM card.
  4. Tap (Back button) to set the other SIM card.

Renaming a SIM card

  1. Find and tap [Settings] > [Network & internet] > [Mobile network].
  2. Select a SIM card.
  3. Tap (Edit icon) beside the SIM card name, and then enter a new name.
  4. Tap [Save].

Selecting which SIM card handles data traffic

  1. Find and tap [Settings] > [Network & internet] > [Mobile network].
  2. Select a SIM card.
  3. Tap [Data preference].
  4. Select the SIM card you want to use for data traffic.

Setting the default SIM card for placing a call

  1. Find and tap [Settings] > [Network & internet] > [Mobile network].
  2. Select a SIM card.
  3. Tap [Calls preference].

Enabling the Dual SIM reachability function

  1. Launch the Phone app.
  2. Tap (More icon) > [Settings] > [Calling accounts] > [Dual SIM reachability].
  3. Tap the switch to enable the function.
  4. Follow the on-screen instructions to complete the procedure.


Note

  • The Dual SIM reachability function may not be available depending on the combination of network operators that provided the SIM cards.

Hint

  • If you set one SIM card for calling and the other SIM card for data communications, you may not be able to access the internet while talking on the phone. In this case, turn on the [Data during calls] switch of the SIM card for calling. You will now be able to perform data communications even during calls.
  • If the Dual SIM reachability function does not work after you enable it, check that you have entered the phone numbers correctly for each SIM card. In some cases, the numbers are detected automatically during setup. Otherwise, you are prompted to enter them manually.
