Samsung Galaxy S24 and S25: eSIM setup for travel

If you own a Galaxy S24, S24+, S24 Ultra, S24 FE or any S25 model, your phone already has eSIM built in. That means no shop queue at the airport and no swapping the tiny tray card that holds your regular number.

This guide walks through the exact Samsung menus, the right order to do things, and the one setting that stops most travel headaches before they start.

Does the Galaxy S24 and S25 support eSIM?

Yes. Every Galaxy S24 and S25 sold internationally ships with eSIM support, and so does any Samsung Galaxy from the S20 on. If you are unsure about an older or region-specific model, run the universal check: dial *#06#. If an EID number appears on the screen next to the IMEI, your phone can take an eSIM.

Two more conditions matter. First, the phone must be carrier-unlocked. A handset still locked to a home operator will reject a foreign profile, and no provider can fix that remotely — you ask your carrier to unlock it. Second, the eSIM is data only: it gives you internet, not a new phone number. WhatsApp, Telegram, FaceTime audio, Google Maps and email all run over that data, and your own number stays alive on your physical SIM.

VoaSim does not sell physical SIM cards. If your Samsung has no EID, a local SIM abroad is the better route. See our eSIM destinations to check coverage first.

Install the eSIM on your Samsung: step by step

Do this at home, on Wi-Fi, before you fly. Installation takes about two minutes.

1. Buy the plan in the price simulator. The QR code arrives by email within minutes.
2. On the Samsung, open Settings > Connections > SIM manager.
3. Tap Add eSIM, then Scan QR code from service provider.
4. Point the camera at the QR code on another screen or on paper. If scanning fails, choose Enter activation code manually and paste the code from the email.
5. Confirm the download and rename the line something obvious, like "Travel".

Now the critical part: after installing, turn the eSIM line off and leave it off. In SIM manager, toggle the travel line to off. Your days only start counting at the first connection to a network at the destination, so an eSIM switched on at home can begin the clock early. On Android in particular, do not enable mobile data on the eSIM before the trip.

What to do when you land

After the plane doors open, three taps get you online.

• Open Settings > Connections > SIM manager and switch the travel eSIM on.
• In Mobile networks, set Mobile data to the VoaSim line and make sure Data roaming is enabled for that line — the eSIM connects to local partner networks, so roaming must be allowed on it.
• Turn off data roaming on your physical SIM so your home carrier cannot bill you. Keep the SIM itself active for SMS codes and calls if you want them.

The phone then attaches automatically to a local network on 4G, or 5G where the partner network offers it. First registration can take one to three minutes; airplane mode on and off usually speeds it up.

One habit worth keeping: set the travel eSIM as the default for mobile data only, not for calls and messages. That way your number behaves exactly as it does at home.

Prices: one rate for every destination

VoaSim charges by duration, not by country or by gigabyte. The same plan works across 170 destinations, and the Europe plan covers 50 countries with a single eSIM. Prices below include today's 15% promo.

Trips of one to four days pay the 5-day package. A second eSIM in the same order gets 10% extra off — handy if two Samsungs are travelling together. Maximum 90 days per eSIM. Payment is by international credit or debit card in USD through Stripe, invoice by email, no hidden fees.

Data is truly unlimited: no cap, no throttling, no quiet fair-use clause. Check your exact price in the simulator.

No signal on your S24? Run these checks in order

Most Samsung eSIM problems are settings, not hardware. Work down the list.

1. Is the eSIM line on? Settings > Connections > SIM manager, travel line toggled on.
2. Is data roaming enabled on that line? This is the single most common miss on Android.
3. Is mobile data pointed at the eSIM? In SIM manager, set preferred SIM for mobile data.
4. Restart the phone, or toggle airplane mode for 30 seconds.
5. Search manually. Mobile networks > Network operators > turn off automatic selection and pick a local carrier from the list.
6. Switch network mode to LTE/3G/2G auto instead of 5G-only.
7. Check APN. Support can confirm the correct one for your destination.

Still nothing? Use the free eSIM Rescue tool — it diagnoses an eSIM of any brand, not just ours. Human support answers by chat or at hola@voasim.com. If the eSIM will not connect and support cannot fix it, you get a 100% refund. More on how we handle that on the trust page.

Other options for a Samsung traveller

Fair comparison matters more than a sales pitch. Your Galaxy S24 accepts any eSIM brand, so pick by how you use data.

Carrier roaming (T-Mobile, AT&T International Day Pass, Verizon TravelPass, EE, Vodafone, Three, Telstra, Rogers) keeps your number for calls and texts and can be worth it for a two-day trip. It is usually billed per day of use with a daily allowance and slower speeds afterwards, and it normally must be switched on before you leave. Check the current rate for your country in your carrier app.

Per-GB eSIM apps like Airalo, Nomad, Ubigi or Saily suit light users who mostly read email on hotel Wi-Fi. Read each brand's terms for validity, caps and tethering rules.

A local SIM is often cheapest for long stays, but it means a shop, passport registration in most countries and pulling your own SIM out of the phone.

VoaSim fits heavy users: maps, streaming, video calls, uploading photos, no counting megabytes. Compare on our comparison page or browse Europe coverage.
