VoLTE in Israel 2025: Which carriers support it, how to enable 4G calling, device compatibility, and troubleshooting

Let’s be honest: if voice calls used to be “just another service,” in 2025 they depend on 4G more than ever. Why? Because 3G networks are gradually shutting down, and carriers are pushing everyone to VoLTE—voice calls that run over 4G data. Sounds complicated? Not at all. From our experience with customers, a few correct settings and a compatible device are enough to get crisp calls, faster call setup, and full internet use during a call. That simple.

In this post we’ve gathered everything you need to know: which carriers in Israel support it, how to actually enable it, which devices work great (and which sometimes “stutter”), what to do when visiting Israel with a prepaid SIM or eSIM, and the most common mistakes we’ve seen—plus how to fix them in two minutes.

What is VoLTE anyway and why does it matter in 2025?

VoLTE (Voice over LTE) is a technology that lets voice calls run on the 4G network instead of falling back to 3G or 2G. The result? HD-quality calls, near-instant call setup, and keeping 4G/5G data active during the call.

A question we get a lot is: “If I’ve got good signal, why does this matter?” Simple—without VoLTE, the device tries to drop to an older network for calls. When 3G is shut down in a given area, those fallbacks can cause drops, “robotic” audio, or even the inability to place a call. With VoLTE, you stay on 4G, and it’s more stable.

The thing is, VoLTE isn’t just about “voice quality.” It also enables advanced features like stable conference calls, video calls over the cellular network (on some devices and carriers), and more efficient battery usage because the phone isn’t constantly switching technologies. Bottom line—in 2025, VoLTE is the right default.

Who supports VoLTE in Israel in 2025? A field snapshot

We’ve heard tons of questions like “Does my carrier support it? Does it work on prepaid? What about eSIM?” In practice, most major carriers have supported VoLTE for years, and in 2025 it’s broadly standard. The differences are in the details: approved device models, automatic vs. manual activation, and full support on prepaid lines and eSIM.

From our extensive hands-on experience, here’s the practical summary:

Network operators (MNOs): Pelephone, Partner, Cellcom, and HOT mobile—support VoLTE on most modern devices, including iPhone and popular Androids (Samsung/Xiaomi/Pixel). In some cases you’ll need a device software update or “Carrier Settings” update.
MVNOs: Golan Telecom, 012 Mobile, We4G, Rami Levy, 019 and more—support exists, but sometimes partial or dependent on device and approved model lists. We’ve seen differences between postpaid lines and older prepaid plans.
eSIM: On most carriers that offer eSIM—VoLTE is supported, but it depends on the device and the carrier profile. Tourists with iPhone 12 and up are almost always covered; Android has more nuances.

To make it clearer, here’s a rough field guide (may vary by model and plan):

Operator type	Example companies	VoLTE support in 2025	Notes from the field
Network operators (MNOs)	Pelephone, Partner, Cellcom, HOT mobile	Yes, broad	Sometimes you need to swap an old SIM and update “Carrier Settings”
Large MVNOs	Golan, 012, We4G, Rami Levy, 019	Usually yes	Possible exceptions on non-“approved” models or older prepaid bundles
eSIM	With most carriers	Usually yes	Depends on eSIM profile; excellent on iPhone, variable on Android

Gold tip: Even when the carrier “supports” it, your device needs to be on the list of validated models or at least support generic IMS profiles. If not—you’ll see the VoLTE toggle grayed out, or you’ll get “no network” during calls in areas without 3G.

How to enable 4G calling? A quick guide for iPhone and Android

Let’s run through it step by step. Sounds complex? Not at all. Two minutes and you’ve got VoLTE.

iPhone:

Open Settings > Cellular > Cellular Data Options > Voice & Data.
Choose 4G or LTE, and enable VoLTE (in some cases you’ll see “Voice & Data: LTE,” which already includes it).
Make sure your iPhone is updated to the latest iOS. You may get a “Carrier Settings Update” pop-up—approve it.

Android (Samsung as reference):

Settings > Connections > Mobile networks > VoLTE calls (SIM 1/2) > On.
Ensure the network mode is “4G/5G Auto.” Sometimes “Prefer 3G” will block it entirely.
If you don’t see the option—update device software, reinsert the SIM, or move to an area with solid 4G.

For those who like to check deeper: on some Android devices, the service code ##4636## shows IMS Registration status. If it says “Registered”—you’re on track. Doesn’t work on every model, but useful for diagnosis.

Device compatibility: iPhone, Samsung, Xiaomi, Pixel and Dual SIM

iPhone: From iPhone 6 onward, VoLTE is supported, and on current iOS it usually works “out of the box.” On iPhone 12 and up we’ve hardly seen issues, including with eSIM. Sometimes a small “Carrier Settings” update is needed—it appears automatically.

Samsung: Galaxy models from S8 and up support it well. In the A series, VoLTE menus can be hidden until a software update. It’s important to use a standard Israel/Europe firmware region; unusual overseas variants can hide the toggle.

Xiaomi/Redmi/POCO: This is where we see the most variation. Sometimes the device supports it, but the carrier profile is missing, so the toggle isn’t available. We’ve solved such cases with MIUI/HyperOS updates, swapping to a newer SIM, or switching to a plan with official support. It’s also worth trying a network settings reset.

Pixel: On Pixels imported from the U.S., early versions blocked VoLTE on unapproved carriers. Since Android 13 this is generally resolved, but some region-specific models still depend on the carrier. A full system update usually does the trick.

And Dual SIM:

On many devices, only one SIM can use VoLTE at a time, or both may have VoLTE but Wi‑Fi Calling works on only one.
If you run two lines from different carriers—check which one gives you more stable VoLTE and set it as the default line for calls.
eSIM + nano‑SIM together typically work great, but if one “grabs” IMS, switch the default for calls and test again.

Common issues and fixes: What to do when VoLTE refuses to work?

From our customer experience, 80% of issues are solved with the following steps:

Toggle Airplane mode on/off for 20 seconds.
Remove and reinsert the SIM; if it’s very old (64K/72K)—ask the carrier for a new SIM.
Update device software and carrier settings; toggle VoLTE off/on and set network mode to “4G/5G Auto.”
Reset network settings: on iPhone Settings > General > Transfer or Reset > Reset > Reset Network Settings. On Android—per manufacturer.
Enable Wi‑Fi Calling as a backup, especially at home where 4G is weak.

If it still doesn’t work:

Check there’s no block in your account settings at the carrier side (some MVNOs need VoLTE support “flagged”).
Make sure your number isn’t set with a “content filtering/parental routing” profile that restricts IMS (we’ve seen this twice on family plans).
Try a different coverage area. If VoLTE works in the city but not in your town—it points to coverage/regional profile.

Frequently asked questions from the field:

Question: I have full 4G, why is the call dropping?
Answer: IMS may not be registered, and the device is trying to fall back to 3G which isn’t available there. A carrier settings update/SIM swap usually fixes it.
Question: My prepaid doesn’t have VoLTE. Is it a lost cause?
Answer: Not at all. At most major carriers you can swap to a newer SIM or move to a prepaid plan that supports it. Ask explicitly for VoLTE support.
Question: Do I need a special APN?
Answer: No. VoLTE runs on a separate IMS profile configured automatically. The data APN usually doesn’t affect it.

Myths debunked:

“VoLTE drains battery” — in practice, fewer network switches = slight savings.
“It only works on 5G” — not true. VoLTE is over 4G; even on 5G you still need 4G active for calls on most models.
“Any 4G phone supports VoLTE” — depends on the manufacturer and carrier approval. Not every model enables IMS in Israel.

Tourists, prepaid, and businesses: why it matters even more

Tourists in Israel: If you arrive with a recent iPhone—you’ll usually enjoy VoLTE immediately, especially with a local eSIM. On Android, models intended for certain markets (mainly U.S./Asia) may require software tweaks and sometimes won’t get full IMS. Our recommendation: enable Wi‑Fi Calling too when possible.

Prepaid: One of the most common questions we get. In 2025, most major carriers’ prepaid supports VoLTE, but older lines or old SIMs may lack support. The fix is simpler than you think: swap the SIM at the carrier for a newer one, or move to a modern prepaid plan.

Businesses: If you run field teams, couriers, or drivers—stable calls during navigation and hotspot use are critical. VoLTE allows full data during calls without drops. From our experience, those who switched to VoLTE and ensured device compatibility dramatically reduced “call drops” in the field.

Bottom line—quick self-checks

Does it show LTE/4G during a call? If yes—it’s probably VoLTE. If the device drops to H+ or 3G—probably not.
Is VoLTE enabled in the device menu? If the option is missing—update software/contact the carrier.
Coverage check: weak 4G areas can trigger call fallback. Check whether your area has stable 4G.

A small tip worth a lot: if you’re on Dual SIM and the device refuses to register IMS, temporarily remove the second SIM, toggle VoLTE on/off, then reinsert. This “aligns” quite a few devices.

Brief comparison: VoLTE vs. Wi‑Fi Calling—when to use what?

VoLTE: the natural choice outdoors and on the move. Stable quality, short setup time, data stays active during the call.
Wi‑Fi Calling: perfect at home/office with weak cellular but strong Wi‑Fi. Incoming/outgoing calls go over Wi‑Fi.
Together is ideal: enable both, and the device will pick the best option at any moment.

Real case: a customer in Eilat complained about evening drops. We enabled VoLTE and Wi‑Fi Calling, updated “Carrier Settings,” and swapped the SIM. Since then—zero complaints, even while watching YouTube during a call.

Pre-support checklist

New and up-to-date SIM? If it’s old—replace it.
Device software updated? Yes, even a security patch can include IMS updates.
Network mode: 4G/5G Auto, not 3G/2G.
VoLTE toggle enabled.
Try a call where 4G is strong (open area/city center) to rule out coverage.
Enable Wi‑Fi Calling as backup.

If none of that works—contact your carrier support and ask them to check “VoLTE/IMS provisioning” on your line. Sounds technical? That’s exactly what moves the needle.

Summary and call to action

In 2025, VoLTE isn’t a “nice feature”—it’s the backbone of reliable calling in Israel. As more areas reduce 3G, those who enable VoLTE enjoy cleaner audio, faster call setup, and continuous internet use during calls. This is especially true for tourists, prepaid users, and anyone who works extensively in the field.
