Urgency

Medium

Quick answer

With two SIMs in your Pixel, a "Voice unavailable" or "Voice interruptions" notification means, per Google, that the networks on both cards have trouble working together. The fix mostly lies with your carrier: check settings, then contact them.

Safety first

Stop and check this first

  • If you rely on the phone for emergencies, never leave both SIMs off during testing and confirm at least one line can place calls.
  • Reset Bluetooth & Wi-Fi deletes your saved Wi-Fi networks; if you only want to test the mobile side, use Reset mobile network settings.

Safe checks you can perform

  • Check which SIM handles each function
  • Turn one SIM off temporarily to isolate the clash
  • Review the dual SIM calling requirements
  • Check VoLTE and reset mobile network settings

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Ask the carrier about the two SIM combination
  • Do not attempt this professional task: Google repair check if no line works

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Ask the carrier about the two SIM combination

    What they doGoogle sends you to your mobile carrier when the dual SIM voice notification appears, since the carrier knows how its network coexists with others.

    They must show youthe status of your line in their system and any network incidents in your area.

    In writingthe ticket number, the change applied to the line and the IMEI 1, IMEI 2 or EID they recorded.

  2. Google repair check if no line works

    What they doIf the Pixel cannot call on any carrier even with one SIM and after a network reset, Google's official repair service assesses the phone.

    They must show youthe call test with each SIM and the result of their diagnosis.

    In writingthe repair number, the Pixel IMEI, the diagnosis and the warranty coverage.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Check which SIM handles each function

    No special tools

    Who:
    you, in the Pixel Settings app.
    How:
    open Settings, tap Network & internet and then SIMs. Under "Your primary SIMs" see which SIM is chosen for Calls, Texts and Mobile data, and whether any is set to Ask every time.
    Result that matters:
    knowing which line is trying to place calls when the notification shows.
    If the calling SIM is not the one you expected:
    change it and place a test call.
    If everything is as you wanted:
    move on to the test of turning one SIM off.
    Evidence to keep:
    a screenshot of the SIMs screen with the preference for each function.

  2. Turn one SIM off temporarily to isolate the clash

    No special tools

    Who:
    you, with a few minutes to test calls.
    How:
    in Settings, Network & internet, tap the SIM you want to switch off and turn off Use this SIM. Place a test call on the other line, then repeat with the SIMs swapped.
    Result that matters:
    seeing whether the voice notification disappears when only one line is active.
    If calls work with a single SIM:
    the problem is the combination of the two networks.
    If it fails even with one SIM:
    that line has the fault and you need to speak to its carrier.
    Evidence to keep:
    which SIM was active in each test and whether the call connected.

  3. Review the dual SIM calling requirements

    No special tools

    Who:
    you, if you have a Pixel 8a or later.
    How:
    in Settings, Network & internet, SIMs, confirm Mobile data is on for both lines and Automatic data switching is on for the second one. Ask that carrier whether it supports Wi-Fi calling.
    Result that matters:
    meeting the three conditions Google sets for using both SIMs for calls.
    If one was missing:
    turn it on and test a call on each line again.
    If all were already in place:
    the clash is on the network side and the carrier must review it.
    Evidence to keep:
    the state of each toggle and the carrier answer about Wi-Fi calling.

  4. Check VoLTE and reset mobile network settings

    No special tools

    Who:
    you, when the earlier tests do not clear the notification.
    How:
    in Settings, Network & internet, SIMs, select each carrier and verify the VoLTE status. If nothing changes, go to System, Reset options and Reset mobile network settings.
    Result that matters:
    ruling out a stored voice or network setting that causes the conflict.
    If the notification goes away:
    note which setting fixed it in case it returns.
    If it stays:
    contact your carrier to rule out outages in your area or changes to your plan.
    Evidence to keep:
    the VoLTE status of each line and the time you reset the network settings.

What it means

Google's help page "How to use dual SIMs on your Google Pixel phone" explains that some combinations of SIM networks do not work well together and that a "Voice unavailable" or "Voice interruptions" notification then appears. The page "Fix mobile connectivity issues" says to contact your carrier about SIM error messages. The notification alone never proves that the phone has a faulty part. Other models, carriers or Android versions may behave differently.

    Evidence: How to use dual SIMs on your Google Pixel phone

  • VoLTE disabled or unstable on one linePossible

    Google says that when calls drop or voice struggles to stay connected, Voice over LTE may be disabled or unstable on that SIM.
