How to Turn VoLTE On or Off on Android & iPhone Smartphone
Quick answer: On most Android phones, go to Settings → Network & Internet (or Connections) → Mobile Network → and toggle “VoLTE Calls” or “Enhanced 4G LTE Mode.”
On iPhone, go to Settings → Cellular → Cellular Data Options → Voice & Data, and choose 4G/LTE to enable VoLTE, or 3G to disable it.
One important exception: if you’re on Jio, you can’t turn VoLTE off at all. Jio runs entirely on VoLTE with no 2G/3G fallback, so disabling it isn’t an option on that network.
If you’ve landed here because your calls suddenly sound different, you spotted an “HD” icon next to your signal bars, or you’re simply trying to fix a “VoLTE not available” message, this guide covers all of it; what VoLTE actually is, exactly how to turn it on or off on your specific phone, and the India-specific quirks (especially around Jio, Airtel, Vi, and BSNL) that most guides on this topic skip entirely.
What Is VoLTE, in Plain Terms?
VoLTE stands for Voice over LTE. Instead of your voice call dropping down to an older 2G or 3G connection, the way calls traditionally worked, VoLTE carries your call as data over the same 4G LTE network your internet already runs on.
This matters for three practical reasons:
- Clearer call quality. VoLTE supports HD Voice codecs, so calls genuinely sound sharper than old-style calls; this isn’t just marketing language, it’s a real difference in audio bandwidth.
- Faster call connection. Calls typically connect in a couple of seconds with VoLTE, compared to the longer setup time of falling back to 2G/3G.
- You can use data and call at the same time. On a non-VoLTE connection, many networks force your phone to drop to 3G or 2G for the duration of a call, which can pause or slow your internet. VoLTE avoids this entirely since voice and data both ride the same 4G connection.
VoLTE vs ViLTE vs VoWiFi/Wi-Fi Calling; Don’t Mix These Up
This is a common point of confusion, so it’s worth clarifying upfront:
| Term | What it actually is |
|---|---|
| VoLTE | Voice calls carried over your 4G mobile network |
| ViLTE | Video calls carried over your 4G mobile network (the video equivalent of VoLTE) |
| VoWiFi / Wi-Fi Calling | Voice calls carried over a Wi-Fi connection instead of a mobile network, useful when you have a weak cellular signal but a strong Wi-Fi connection (indoors, basements, rural areas) |
You’ll often see all three options sitting next to each other in your phone’s network settings, which is exactly why people frequently confuse “enabling VoLTE” with “enabling Wi-Fi Calling.”
They solve different problems: VoLTE depends on your mobile signal, and VoWiFi depends on your internet connection.
VoLTE on Indian Networks: What’s Actually Different in 2026
This is the part most generic guides miss entirely, and it changes the advice depending on which network you’re using.
- Jio: Jio’s network is built entirely on VoLTE. There’s no 2G or 3G voice fallback at all. This means VoLTE is on by default and cannot be turned off on a Jio SIM. If you ever see a “VoLTE not showing” issue on Jio, it’s a device or registration problem to troubleshoot, not a setting to toggle. See the troubleshooting section below.
- Airtel and Vi (Vodafone Idea): Both support VoLTE with a visible toggle (“Enhanced 4G LTE Mode” or similar) in your phone’s settings, alongside fallback to 3G/2G if needed.
- BSNL: VoLTE is now provided by default to BSNL 4G customers as part of its expanded 4G rollout. If it’s not showing up on your device, BSNL’s activation method is slightly different from other carriers. Send ACTVOLTE as an SMS to 53733, or call 53734, then enable VoLTE in your phone’s network settings. Activation can take a few hours to reflect. BSNL has also rolled out VoWiFi (Wi-Fi Calling) nationwide, which is worth enabling separately if you have a stable home broadband connection and a patchy indoor mobile signal.
Quick answer : “Can I turn off VoLTE on Jio?” No. Jio’s network doesn’t support traditional 2G/3G voice calls, so VoLTE stays on for all calls regardless of your phone’s settings.

How to Turn On VoLTE on Android
The exact wording varies by brand, but the general path is consistent across most Android phones:
- Open Settings.
- Tap Network & Internet (some phones: Connections).
- Tap Mobile Network (or SIM & Network), and select your SIM if you have two.
- Look for Advanced if VoLTE isn’t immediately visible.
- Find “VoLTE Calls”, “Enhanced 4G LTE Mode”, or “4G Calling”, and toggle it on.
- Restart your phone if the toggle doesn’t take effect immediately.
Brand-specific notes:
- Samsung (One UI): Settings → Connections → Mobile Networks → tap your SIM → VoLTE Calls.
- Xiaomi (HyperOS/MIUI): Settings → SIM Cards & Mobile Networks → [Your SIM] → Preferred Network Type / VoLTE toggle.
- OnePlus/Realme/Vivo: Settings → SIM & Network → [Your SIM] → Enable 4G Calling (VoLTE).
- Stock Android (Pixel, Nothing, Motorola): Settings → Network & Internet → SIMs → [Your SIM] → tap “Calls preference” or “VoLTE calls.”
If you genuinely don’t see a VoLTE option anywhere, jump to the troubleshooting section. This usually means either your device or your specific SIM/plan combination doesn’t support it yet, not that you’re looking in the wrong place.
How to Turn On VoLTE on iPhone
- Open Settings.
- Tap Cellular (or Mobile Data, depending on your iOS version and region).
- Tap Cellular Data Options (or Mobile Data Options).
- Tap Voice & Data.
- Select 4G (sometimes labelled LTE with VoLTE support, or 5G Auto/5G On, depending on your network and iOS version) to enable VoLTE.
On most iPhones sold in India, VoLTE activates automatically once your carrier provisions it on your SIM. You often don’t need to do anything manually beyond confirming this setting matches “4G” rather than “3G.”
How to Turn Off VoLTE
If you have a specific reason to disable it (covered below), the steps are simply the reverse:
On Android: Settings → Network & Internet → Mobile Network → [Your SIM] → toggle “VoLTE Calls” or “Enhanced 4G LTE Mode” off.
On iPhone: Settings → Cellular → Cellular Data Options → Voice & Data → select 3G instead of 4G/LTE.
Important: as covered above, this toggle doesn’t exist at all on Jio because the network has no fallback voice mode. On Airtel, Vi, and BSNL, turning it off forces your calls back onto the older 3G/2G voice network .
This means slightly longer call setup times and lower audio quality, and on networks actively shutting down 3G, may eventually stop working for calls entirely as those legacy networks get phased out.

Why Would You Actually Want to Disable VoLTE?
The honest answer in 2026: rarely, and for most people, not at all. But there are a few legitimate scenarios:
- Persistent call quality issues specific to VoLTE in your area; if VoLTE is genuinely behaving worse than a 3G fallback in a specific weak-coverage location, temporarily disabling it can help, though this is increasingly uncommon as networks mature.
- A specific device-network compatibility bug that your carrier’s support team has explicitly asked you to test by toggling VoLTE off and back on.
- Travelling to an area where your carrier’s VoLTE coverage is unreliable but 3G coverage is more consistent (this is becoming rarer as 3G networks shut down across India).
Battery life is no longer a strong reason for most modern phones. See the Myth vs Fact section below for why this commonly repeated claim is outdated.
Troubleshooting: Common VoLTE Problems and Fixes
“No VoLTE Option” in Settings
This usually means one of three things:
- Your phone doesn’t support VoLTE; true for some older or budget devices, particularly those originally sold for 3G-only markets.
- Your network hasn’t provisioned VoLTE on your specific SIM/plan; contact your carrier to confirm and request activation.
- You’re on Jio, where there’s simply no toggle because it’s enabled by default and can’t be turned off.
If you’ve confirmed your current phone genuinely doesn’t support VoLTE, and you’re due for an upgrade anyway, choosing a phone that explicitly lists VoLTE support in its specifications avoids this problem entirely going forward.
Most of the latest generation 4G and 5G smartphones support it, but it’s worth double-checking before you buy, especially with budget devices.
VoLTE Shows as Enabled, but Calls Still Don’t Use It (IMS Registration Issues)
This is a genuinely common and specific problem. Your phone shows the VoLTE toggle as “on,” but calls still go out over 2G/3G or fail to register at all.
This usually points to an IMS (IP Multimedia Subsystem) registration failure. Essentially, your phone’s VoLTE toggle is on, but it hasn’t successfully checked in with your carrier’s VoLTE servers.
Fix it in this order:
- Toggle Flight Mode on, wait 10 seconds, then turn it off; this forces your phone to re-register with the network.
- Restart your phone completely (not just the toggle).
- Remove and reinsert your SIM card, ideally after the phone has been powered off.
- Check for a pending software/carrier settings update; VoLTE provisioning updates are sometimes delivered through these rather than a manual toggle.
- As a last resort, do a network settings reset (Settings → General Management/System → Reset → Reset Network Settings). This clears any corrupted network profile that might be blocking registration.

Dual-SIM Phones: Why VoLTE Might Only Work on One SIM
A lot of dual-SIM users run into this without realising it’s a hardware limitation rather than a setting they’ve missed.
Many dual-SIM phones only support VoLTE on one SIM slot at a time (often called “DSDS” without dual VoLTE), meaning your second SIM falls back to 3G/2G for calls, even with VoLTE technically “supported” on the device.
Newer phones increasingly support “Dual VoLTE”, true simultaneous VoLTE on both SIM slots.
If you regularly rely on two SIMs for calls (a common setup in India for separating personal and work numbers), it’s worth specifically checking whether a phone supports Dual VoLTE before buying, rather than assuming standard VoLTE support covers both slots.
If juggling two active SIMs for calls is a daily reality for you, looking specifically for a phone advertised with Dual VoLTE support saves you from the frustration of one SIM silently falling back to lower call quality.
It’s listed in the spec sheet of most current mid-range and flagship phones (you can check on Amazon), so it’s worth checking before purchase rather than discovering the limitation afterwards.
Calls Drop or Sound Choppy Even With VoLTE Enabled
- Check that you’re in an area with adequate 4G coverage; VoLTE depends entirely on a stable 4G signal, so patchy 4G means patchy VoLTE calls, regardless of the setting.
- Confirm your network mode isn’t locked to “3G only” or “2G only,” which would prevent VoLTE from working at all, even if the toggle is on.
- If the issue is consistent and area-specific, it’s worth checking your carrier’s official network status/coverage map for known issues before assuming it’s a device problem.
Common Mistakes Users Make With VoLTE Settings
- Assuming Jio has a VoLTE toggle hidden somewhere, it doesn’t, by design, since there’s no fallback network to switch to.
- Confusing VoLTE with Wi-Fi Calling (VoWiFi) and troubleshooting the wrong setting when calls aren’t connecting.
- Toggling VoLTE off to “save battery” on a modern phone is based on outdated advice that no longer reflects how efficiently current devices and networks handle VoLTE.
- Not checking the IMS registration first before assuming a hardware fault, when a simple Flight Mode toggle often resolves the same symptom.
- Buying a phone without confirming Dual VoLTE support, then being surprised when the second SIM’s call quality is noticeably worse.

Myth vs Fact: VoLTE
| Myth | Fact |
|---|---|
| “VoLTE drains your battery significantly faster.” | This was a more valid concern in early VoLTE implementations years ago. On current-generation phones and mature VoLTE networks, the difference in battery drain is minor for most users, far smaller than the cost of dropping to a less efficient older voice network. |
| “VoLTE uses a meaningful chunk of my data plan.” | Voice data carried over VoLTE is genuinely small. Calls use only a modest amount of data, nowhere close to the consumption of streaming or browsing, and shouldn’t noticeably affect your monthly data allowance. |
| “You can disable VoLTE on any Indian network if you want to.” | Not true for Jio, where VoLTE is the only way voice calls work at all. There’s no toggle because there’s no fallback network. |
| “VoLTE and Wi-Fi Calling are the same feature.” | They’re related but distinct. VoLTE runs over your mobile 4G network, while Wi-Fi Calling (VoWiFi) runs over your internet connection, and they’re toggled separately. |
| “If VoLTE shows as ‘on,’ your calls are definitely using it.” | Not always; IMS registration can silently fail, leaving the toggle on while calls quietly fall back to an older network. This is a common, fixable issue rather than a sign that your phone doesn’t support VoLTE. |
Decision Guide: Should You Turn VoLTE On or Off?
- On Jio: Not applicable; it’s always on, and there’s nothing to decide here.
- On Airtel, Vi, or BSNL, and you’re not experiencing any issues: Leave it on. The call quality and connection speed benefits are real, and the battery/data concerns are largely outdated for modern devices.
- Experiencing specific call quality problems only since enabling VoLTE: Try the IMS registration fix above first. Only disable VoLTE as a temporary diagnostic step if your carrier’s support team specifically suggests it.
- Travelling somewhere with known patchy 4G but solid 3G coverage: Temporarily disabling VoLTE (where the toggle exists) may genuinely help in that specific situation. Re-enable it once back in a stronger 4G area.
- Using a dual-SIM setup for calls on both numbers regularly: Check Dual VoLTE support before assuming both SIMs will behave identically.
Since VoLTE’s main real-world benefit is noticeably clearer call audio, pairing it with a decent pair of earphones or a Bluetooth headset with a good microphone (find on Amazon) actually lets you hear (and be heard in) that improved call quality, rather than the gain being wasted on a phone’s weak built-in speaker.

Expert Tips for a Smoother VoLTE Experience
- If you’ve just switched SIMs or phones, give VoLTE provisioning up to 24 hours before assuming it’s broken. Carrier-side activation isn’t always instant, especially on BSNL’s manual activation process.
- Keep your phone’s software and carrier settings updated. VoLTE-related bug fixes and provisioning updates are frequently delivered this way rather than through a setting you’d find yourself in.
- If you split calls across two SIMs, test call quality on both numbers specifically, rather than assuming VoLTE coverage is identical for each.
- When troubleshooting, isolate whether the issue is location-specific (test in a different area) before concluding it’s a device fault.
The Future: VoLTE, 5G, and What’s Next
As 5G networks expand across India, voice calling is gradually shifting toward VoNR (Voice over New Radio) – the 5G-native equivalent of VoLTE.
In practice, most current 5G phones still rely on VoLTE for voice calls even on a 5G data connection (a setup sometimes called EN-DC), since full VoNR rollout is still in earlier stages across most circles.
For the average user, this transition will likely be invisible; the same way most people never noticed the shift from old-style calls to VoLTE in the first place, beyond clearer audio and faster connection times.
Conclusion
VoLTE is one of those background technologies that quietly makes your calls clearer and faster without requiring much thought, once it’s working correctly.
The actual setting is simple on every phone once you know where to look.
But the real troubleshooting skill is knowing the difference between “VoLTE isn’t supported,” “VoLTE isn’t provisioned by my carrier yet,” and “VoLTE is on but not registering properly” – three different problems that look identical from the settings screen.
If you’re on Jio, there’s nothing to toggle at all. If you’re on Airtel, Vi, or BSNL and something feels off, start with the IMS registration fix (Flight Mode toggle, restart, SIM reseat) before assuming your device or network doesn’t support it.
That simple sequence resolves the large majority of “VoLTE not working” cases in practice.
Frequently Asked Questions
No. Jio’s network runs entirely on VoLTE with no 2G/3G voice fallback, so there’s no toggle to disable it. It’s on by default for all calls.
Go to Settings → Network & Internet (or Connections) → Mobile Network → select your SIM → toggle “VoLTE Calls” or “Enhanced 4G LTE Mode” on. Exact wording varies slightly by phone brand.
Go to Settings → Cellular → Cellular Data Options → Voice & Data, and select 4G (or the LTE option with VoLTE support) instead of 3G.
Either your device doesn’t support VoLTE, your carrier hasn’t provisioned it on your SIM yet, or you’re on a network like Jio where it’s enabled by default with no visible toggle.
VoLTE calls do use mobile data instead of the older circuit-switched voice network, but the amount used per call is small and shouldn’t noticeably affect your monthly data allowance.
On current-generation phones, the difference is minor. This was a more legitimate concern with early VoLTE implementations years ago, but modern hardware and mature networks have largely closed that gap.
Send “ACTVOLTE” as an SMS to 53733, or call 53734, then enable VoLTE in your phone’s mobile network settings. Activation can take a few hours to take effect.
VoLTE carries voice calls over your mobile 4G network, while Wi-Fi Calling (VoWiFi) carries calls over your internet/Wi-Fi connection instead. It is useful when the mobile signal is weak, but Wi-Fi is strong.
This usually points to an IMS registration failure. Here, your phone’s settings are on, but it hasn’t successfully registered with your carrier’s VoLTE servers. Toggling Flight or Airplane Mode on and off, or restarting your phone, usually fixes this.
Only on phones that specifically support “Dual VoLTE.” Many dual-SIM phones support VoLTE on only one SIM slot at a time, with the second SIM falling back to 3G/2G for calls.
It’s not strictly mandatory on networks that still support older voice modes (Airtel, Vi, BSNL), but it offers clearly better call quality and faster connection. On Jio, it’s the only option, since there’s no fallback.
Sometimes, in specific weak-4G-coverage areas, but it’s usually better to first check for an IMS registration issue, since that often causes the same symptoms without being a true coverage problem.
It depends on whether your carrier has a VoLTE roaming agreement with the partner network in that country. Check your specific carrier’s international roaming VoLTE coverage list before travelling.
HD Voice refers to the improved audio quality that VoLTE calls typically deliver, thanks to better audio codecs. It’s a result of VoLTE, not a separate feature you enable independently.
This is usually an IMS registration glitch rather than a setting change. Restarting your phone, toggling Flight Mode, or reseating your SIM card resolves most of these cases.
Yes, both can be enabled simultaneously; your phone typically prioritises Wi-Fi Calling when the Wi-Fi signal is strong and falls back to VoLTE on mobile data otherwise.
Not necessarily. VoLTE support depends on both the phone’s hardware/software and whether the carrier has provisioned it for that specific device and SIM combination.
Yes, most current 5G phones still use VoLTE for voice calls even on a 5G data connection, since full native 5G voice (VoNR) is still rolling out gradually across most networks.
Look for an “HD” or “VoLTE” icon near your signal bars when on a call, or check your network settings. Most phones show a dedicated VoLTE status indicator once it’s actively connected.
Only if you’re experiencing specific roaming issues and your carrier’s international VoLTE roaming doesn’t cover that country. Otherwise, leaving it on (where supported by the roaming partner) generally gives better call quality.
