How to Turn VoLTE On or Off on Android and iPhone

VoLTE lets your phone place voice calls over a 4G LTE network instead of dropping to an older cellular network. Turning it on can help you keep LTE data during calls and may improve call connection or clarity where your carrier supports it; turning it off may help with a specific compatibility issue. You’ll need a compatible phone, an active SIM or eSIM, and carrier support, and the exact setting name can vary by device and network.

What You’ll Need

An Android phone or iPhone with a current system update, if available.
A working SIM or eSIM and a mobile plan on a carrier that supports VoLTE for your device.
Cellular coverage. Connect to Wi-Fi if you need to download a system or carrier settings update.

Step-by-Step

Check that VoLTE is available. VoLTE must be supported by both your phone model and your carrier, and it may depend on your plan, SIM, location, or carrier configuration. If you use two SIMs, note which line you want to change. A setting may be hidden or controlled by the carrier even when your phone supports the feature.
Turn VoLTE on or off on many Android phones. Open Settings, then look under Network & internet, Connections, or Mobile network. Select the relevant SIM or mobile network if prompted. Find a control called VoLTE calls, 4G Calling, Enhanced 4G LTE Mode, or a similar name. Switch it on or off, then wait briefly for the phone to apply the change.
Try the alternate Android menu path if needed. Some phones place the control under Settings > SIM cards and mobile networks, Settings > Mobile networks, or the settings page for a particular SIM. Use the Settings search field and search for “VoLTE,” “4G calling,” or “LTE.” If no result appears, check your manufacturer’s support information or ask your carrier whether the setting is available for your model and line.
Turn VoLTE on or off on iPhone. Open Settings > Cellular (called Mobile Service in some regions). If you have more than one line, tap the line you want to change. Tap Cellular Data Options or Mobile Data Options, then look for Voice & Data. Select an option that explicitly includes LTE or 4G calling if one is offered. Depending on your iPhone, iOS version, and carrier, you may not see a separate VoLTE switch; the carrier may enable VoLTE automatically when LTE is selected.
Confirm the change with a call. Make a short call in an area with LTE coverage. If the phone remains on LTE or 4G during the call, that can indicate VoLTE is being used, but the status-bar display is not conclusive on every phone or network. Check whether calls connect normally and whether mobile data behaves as expected. Do not use an emergency number as a test.
Restart if the setting does not take effect. Restart the phone after changing the option, then check the setting again and make another ordinary call. On iPhone, also check Settings > General > About while connected to Wi-Fi; if a carrier settings update is offered, follow the on-screen prompt. On Android, install available system updates through Settings and check with your carrier for any SIM or network provisioning issue.

Common Mistakes

Assuming every phone has a manual switch. Some carriers manage VoLTE automatically, so the option may not appear. Its absence does not by itself prove that VoLTE is off.
Changing the wrong SIM. On dual-SIM phones, the setting may apply to one line at a time. Confirm the selected line before changing it, and verify which line is used for calls.
Confusing Wi-Fi Calling with VoLTE. Wi-Fi Calling uses a Wi-Fi connection for calls; VoLTE uses the carrier’s LTE mobile network. They are separate settings and can often be used independently.
Expecting the display to confirm the feature perfectly. Network icons differ by device, and a phone may not show a distinct VoLTE label. The carrier can confirm whether the line is provisioned for VoLTE.
Turning VoLTE off without considering coverage. Depending on the carrier and local network, calls may then use an older network or may not connect if that network is unavailable. Check with your carrier before disabling it if you rely on mobile calling.

Tips

Keep VoLTE on unless you have a specific reason to disable it and your carrier recommends doing so. It is commonly needed for voice calls where older 2G or 3G networks have been retired.
Use Settings search before browsing every menu. Manufacturers and software versions use different labels and menu locations.
If you travel, remember that VoLTE availability can differ by carrier, country, roaming partner, and plan. A setting enabled at home does not guarantee VoLTE roaming.
After a SIM replacement, eSIM activation, carrier change, or number transfer, allow the line to finish activating and restart the phone before troubleshooting the toggle.

Troubleshooting

The VoLTE option is missing: Check that mobile service is active, select the correct SIM, and search Settings for “VoLTE” or “4G calling.” Install available phone and carrier settings updates. If it remains missing, contact the carrier and ask whether VoLTE is supported and enabled for your exact phone model and line. The carrier may control the option remotely.

The option is on, but calls do not connect or drop: Check signal strength and try an ordinary call outdoors or in another location. Toggle Airplane mode on briefly, then turn it off, or restart the phone. Confirm the SIM is active and that the account has no service interruption. If the problem continues, contact the carrier to check network coverage, line provisioning, and outages.

Calls work only after switching VoLTE off: Turn it back on when practical and ask the carrier to investigate rather than assuming it should stay disabled. The issue could involve coverage, a carrier configuration, SIM provisioning, or software. Avoid resetting network settings as an early step: this can erase saved Wi-Fi networks and other network preferences. If you do reset them, read the confirmation screen first.

iPhone has no VoLTE toggle: Check Settings > Cellular (or Mobile Service) and the options for the specific line. If LTE or 4G is selected and there is no VoLTE switch, the carrier may manage the feature automatically. Ask the carrier whether VoLTE is active on the line; Apple’s menus do not expose the same controls for every carrier.

Frequently Asked Questions

What does VoLTE mean?
VoLTE means Voice over LTE. It carries voice calls over a carrier’s 4G LTE network rather than requiring a separate older voice network.

Should I leave VoLTE on?
Usually, yes, if your phone and carrier support it. It may be necessary for calling on networks where older cellular services are no longer available.

Does VoLTE use mobile data?
It uses the LTE network to carry the call, but voice calls are generally handled as cellular voice service rather than billed like ordinary app data. Plan and billing details vary, so check with your carrier.

Will VoLTE improve call quality?
It can support clearer calls and faster call setup when the carrier, both ends of the call, and network conditions support the relevant features. Results vary, and VoLTE does not guarantee better reception.

Can I use VoLTE and Wi-Fi Calling at the same time?
Both can be enabled if your phone and carrier support them. The phone and network determine which connection is used for a particular call.

Does turning VoLTE off save battery?
Not reliably. Battery use depends on signal, phone, network, and calling conditions; disabling VoLTE is not a dependable battery-saving method.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
