Manage dual SIMs

This information applies only to phones that support dual SIM cards.

With a dual SIM phone, you can insert one or two SIM cards.

When two SIMs are inserted:

Select SIM for calls

Each time you make a call, you can choose which SIM to use. If you don't want to choose each time, you can set a SIM for all outgoing calls, set a SIM for a particular number, or let the phone learn your calling habits to decide for you.

To select a SIM for all outgoing calls:

  1. Go to Settings > SIM cards > Calls.
  2. Touch SIM1 or SIM2.

To select a SIM for a specific number:

  1. Dial a number.

  2. When prompted to select a SIM, check Remember SIM for number. Then touch SIM1 or SIM2.

    The next time you call that number, the phone uses the selected SIM.

Use automatic SIM selection for calls

If you don't set the phone to make all calls using one SIM, you are prompted to select a SIM each time you make a call. Automatic SIM selection learns your calling patterns to determine the best SIM for an outgoing call. For phones sold in Brazil, Automatic SIM selection chooses a SIM for an outgoing call based on your contact's carrier as well as your calling patterns.

To turn Automatic SIM selection on or off:

  1. Go to Settings > SIM cards.

  2. Turn Automatic SIM selection on or off .

    TipIf Automatic SIM selection isn't available, touch Calls > Ask every time.

You can change the SIM any time you make a call. When you dial a number, you'll see the SIM being used; to use a different one, touch Change SIM.

Select SIM for data

If your phone has two SIMs, cellular data is active on only one SIM at a time. You may have selected which to use during initial phone setup.

To change the SIM for cellular data:

  1. Go to Settings > SIM cards > Data.
  2. Touch the SIM to use.
TipFor extra security, you can add a SIM lock to control data usage.

Select SIM for text messages

  1. Go to Settings > SIM cards > SMS messages.
  2. Touch the SIM to use.

Prioritize voice or data usage

If you cannot use voice and data at the same time on your carrier's network, set their priority.

  1. Go to Settings > SIM cards > Connection priority.

  2. Choose one:

    • Data: Incoming calls go straight to voicemail if data is in use.
    • Voice: Incoming calls stop data usage, which resumes when the call disconnects.

Change SIM names and colors

When two SIMs are inserted, you'll see them referenced in apps like Contacts, Messaging, and Phone. To tell them apart more easily, change the default names (SIM1/SIM2) to more meaningful names. You can also change SIM icon color to make them easy to differentiate.

  1. Go to Settings > SIM cards.
  2. Touch the SIM to change.

  3. Change settings as needed:

    • To rename a SIM, touch SIM name, type a new name, then touch OK.
    • To change icon color, touch SIM color, touch a color, then touch OK.
