Japan travel · Call translation
Samsung already translates calls into Japanese — for free. So why Yovoca?
Samsung's Live Translate is the rare one that already handles Japanese, on-device, with nothing needed on the other end — and it's free. It has exactly one catch, but it's a big one: it only exists on a Galaxy phone. The moment you're on an iPhone, a different Android, or a borrowed handset, it isn't there. Here's an honest, side-by-side look.
Let's give Samsung its due up front: of all the built-in phone translators, Live Translate is the one we'd most readily point a traveller to. It does Japanese — which Apple's call translation still doesn't — it runs on the device, it's free, and the restaurant on the other end needs no app and no special phone. If you carry a recent Galaxy, this guide can be short: use it. The honest question is only "what happens on every other phone?" — and that's where a dedicated tool like Yovoca has a job to do.
The honest version
Samsung Live Translate is excellent — genuinely free, on-device, Japanese included, and nothing needed on the other end. Its single limit is that it lives inside One UI, so it only works when the phone in your hand is a Galaxy. Yovoca is built for the other case: calling a business in Japan (or elsewhere in Asia) from any phone — an iPhone, a non-Samsung Android, a hotel landline — and, in time, having a number that's yours so they can reach you back. On a Galaxy, in a casual call, Samsung usually wins. Off a Galaxy, it simply isn't an option.

Where Samsung Live Translate is the right call
For a big slice of situations, Samsung's free feature is the sensible choice, and we'd tell you to use it:
- The phone in your hand is a Galaxy — roughly S22 or newer, or a Z Flip4 / Fold4 or newer, on One UI 6.1 or higher.
- You're calling in one of its supported languages — and Japanese, Chinese, and Korean are on that list, which is exactly where Apple's call translation still falls short.
- It's a one-to-one, casual call, and you don't need anyone to call you back on a number that reads as bilingual.
In that case, open the Phone app, start the call, tap Call assist and turn on Live translate. It runs on the device — processed on-device, so it even works without a data connection — and the person on the other end can be on any phone, including an old landline, with nothing to install. Free and built in beats a separate tool every time it actually covers the call.
Where it stops — the phone has to be a Galaxy
Live Translate has one limit, and it's structural: it's a Galaxy AI feature, so it only exists where One UI does. That plays out in a few ways travellers run into:
- It isn't on an iPhone. If you carry an iPhone, Live Translate simply isn't there — and Apple's own call translation doesn't yet do Japanese, so for that call you're left without a built-in option on either platform.
- It isn't on a non-Samsung Android. A Pixel, a Xiaomi, a OnePlus — none of them have Live Translate. It's specific to Galaxy hardware running One UI, not Android in general.
- It isn't on a phone you borrow. The translator lives on your Galaxy. Reach for a friend's iPhone or a hotel landline and there's nothing to turn on.
- It gives you no number of your own. Like the OS features, it translates the call in front of you. It doesn't give you a line a restaurant can call back, or one that can take a verification text — it just uses your normal number. The moment the conversation needs a callback in the local language, that's outside its job.
What Yovoca does differently — and honestly
Yovoca is a dedicated call layer for exactly the case Samsung can't cover: you make the call yourself, with a live two-way translator, to any number — and your account works from any phone, not just a Galaxy. You speak English; the other side hears natural Japanese, and their reply comes back to you.
From any phone is real, but worth being precise about. From your own phone — iPhone or Android — caller ID recognises your account, nothing to log in. From a borrowed or hotel phone, you dial a Yovoca access number and enter a short PIN. You're billed by where you're calling, from a prepaid balance, not by which handset you used. (The dial-in access number is a planned P1 capability, not day one.)
And to be straight about today's edges: Yovoca is in early access, the cloned-voice and persistent-number pieces are on the roadmap, and we do not hand you a Japanese mobile number or promise to clear SMS-verification walls. Where Samsung is free and shipping on a Galaxy, we say so plainly.

Call Japan in your language — from any phone.
Samsung Live Translate is great if a Galaxy is the phone you have. When it isn't — an iPhone, a Pixel, a borrowed handset, a number you need them to call back — that's the gap Yovoca is built for. You make the call, a live translator is on the line both ways, and your account travels with you, not your hardware. Join the waitlist and reserve your founding line.

Frequently asked
Does Samsung Live Translate work for phone calls?
Yes. On a supported Galaxy phone, Live Translate is built into the Samsung dialer — you tap Call assist, turn on Live translate, and it translates the call in real time and speaks it aloud, with the text on screen. The translation is processed on-device, so it even works offline, and the person on the other end needs no app and can be on any phone, including a landline.
Does Samsung Live Translate support Japanese on calls?
Yes. Japanese is one of Live Translate's supported languages, along with Chinese and Korean — so it can translate a call to a Japanese restaurant or business. The supported list has grown to around 20 languages on newer Galaxy models; it's worth checking the current list for your device.
Which phones support Samsung Live Translate?
It's a Galaxy AI feature, so it only runs on supported Samsung Galaxy devices — roughly the Galaxy S22 series and newer, Z Flip4 / Z Fold4 and newer, and recent Galaxy tablets, on One UI 6.1 or higher. It is not available on an iPhone or on non-Samsung Android phones such as Pixel, Xiaomi, or OnePlus.
If Samsung Live Translate is free, why would I use Yovoca?
If you have a supported Galaxy, Live Translate is the better choice for a casual call — it's free, on-device, and covers Japanese. Yovoca is for a different case: making the call from any phone rather than only a Galaxy — an iPhone, a non-Samsung Android, or a borrowed handset — with a number that's yours so a business can call you back. Yovoca is in early access; Samsung Live Translate is shipping today.
Does the person I call need a Galaxy or an app?
No — for both Samsung Live Translate and Yovoca, the translation happens on your side, so the other person can be on any phone, including a landline, with nothing installed. That part is a genuine tie. The difference is on your end: Live Translate needs your phone to be a Galaxy, while Yovoca works from any phone.
