Samsung Galaxy S24 eSIM: compatibility, setup and travel use

If you are checking whether Samsung Galaxy S24 can use an eSIM for mobile data abroad, the short answer is yes: Samsung’s current support information lists Galaxy S24 among compatible Galaxy phones, and its Galaxy S24 Series guide explains how to add a mobile plan through SIM manager. This is a positive model-level answer, not a guarantee that every unit sold under the same family name exposes identical options. Country, sales region, carrier policy, software version and network configuration can affect eSIM availability.

An eSIM is a digital SIM built into the phone. It lets you add a mobile plan without inserting another physical card, which is useful for maps, messages, tickets, translation, ride-hailing and work during a journey. The eSIM itself does not automatically include a phone number, voice calls or SMS. Treat a travel plan as mobile internet unless its conditions explicitly include other services.

Quick answer for Samsung Galaxy S24

The standard Samsung Galaxy S24 supports eSIM according to current official Samsung device and support information. Regional Samsung specifications list an embedded SIM alongside nano-SIM capability, while Samsung’s support instructions include an Add eSIM action for the S24 Series. The practical question is therefore whether your exact handset shows the eSIM controls and whether the selected plan can be activated on that version.

This table is a guide, not a substitute for checking the handset. An imported or carrier-customised device may differ from a locally sold model.

Does Samsung Galaxy S24 support eSIM in every region?

No single regional label proves compatibility for every individual unit. Samsung’s guidance says eSIM use may depend on the service provider, region or device model. A local release may use a different SIM configuration, a carrier may restrict activation, or a software build may show different menu labels.

Open Settings → About phone and record the model name and model number. Compare it with the box and listing instead of relying on “Galaxy S24” alone. Carrier lock is separate from eSIM hardware: a phone can have an EID and still refuse another carrier’s plan.

Check compatibility before buying an eSIM plan

Samsung’s menu names can vary by Android and One UI version, but the relevant area is SIM manager:

1. Open Settings.
2. Tap Connections.
3. Open SIM manager or SIM card manager.
4. Look for Add eSIM, Add mobile plan or a similar option.
5. If it is present, confirm that the phone is unlocked and can connect to Wi-Fi or existing mobile data.

The presence of Add eSIM is a strong on-device sign that the phone can download a profile. If it is absent, check for software updates, restart the phone, confirm the model number and ask the seller or carrier about that exact unit. Do not delete a working profile just to test the menu.

You can also look for the EID, the embedded-SIM identifier. On many Galaxy versions, open Settings → About phone → Status information and look for EID; some builds place it under status or SIM information. It may also be printed on the box. An EID supports the hardware check, but it does not override a carrier lock.

Use this checklist before paying:

• [ ] The phone is exactly Samsung Galaxy S24, and its model number is recorded.
• [ ] SIM manager contains Add eSIM, Add mobile plan or an equivalent control.
• [ ] An EID is visible in status information or on the box.
• [ ] The device is unlocked, or the carrier has confirmed that another eSIM can be used.
• [ ] Wi-Fi or another data connection will be available during installation.
• [ ] Android and One UI are updated, and the plan’s destination, allowance, validity and activation rule are understood.
• [ ] You know whether data roaming must be enabled for the travel eSIM.
• [ ] Your regular SIM will not accidentally remain the data line.

If the phone was imported or bought second-hand, repeat the check after installing updates and before arranging a plan. A familiar model name does not remove regional or carrier restrictions.

Check your device before paying for a plan, especially if the phone was imported or purchased second-hand.

What to prepare before installation

Install the profile over stable internet. You need Samsung Galaxy S24, access to the selected eSIM in the Kaspersky eSIM Store app or website, and the supplied QR code, activation link or manual details. Read the plan conditions first: check the validity start rule, reinstallation policy and reset consequences.

Kaspersky eSIM Store is an app and website where you can choose, arrange and activate an eSIM with a mobile-data plan for an overseas trip. It is not a mobile operator, network owner or mobile-internet provider. The connection depends on the selected plan, compatible local network arrangements, destination conditions and the phone settings.

How to install and activate eSIM on Samsung Galaxy S24

The steps follow Samsung’s documented Galaxy S24 Series flow. Your labels may differ slightly after an update; select the closest matching option in SIM manager.

Scan a QR code

1. Connect Samsung Galaxy S24 to reliable Wi-Fi or keep an existing data connection active.
2. Open Settings → Connections → SIM manager.
3. Tap Add eSIM or Add mobile plan.
4. Select Scan QR code or Add using QR code.
5. Scan the code supplied with the plan. If it is displayed on the S24, use another phone or computer.
6. Review the plan name and confirm the download.
7. Wait for the profile to finish downloading, check it in SIM manager and label it “Travel.”

Use an automatic or pre-assigned plan

Some providers pre-assign a mobile plan to the phone’s EID. If supported, open Settings → Connections → SIM manager, choose Add mobile plan and follow the prompts. Automatic activation is provider-dependent, and the EID is not the IMEI.

Enter details manually

If the plan supplies manual activation information, choose Add mobile plan and then Add using activation code, if shown. Enter the server address and code exactly as supplied; never publish a complete QR code or activation code.

For more help, use the Android installation instructions and, when helping with an iPhone, the iOS installation instructions. Android is the relevant path for Samsung Galaxy S24. Do not install the same plan on another phone unless allowed.

Installation and activation can be separate events. A profile shown in SIM manager is installed, but the destination network may not register until arrival. Follow the plan’s activation conditions.

Set Samsung Galaxy S24 to use eSIM for travel data

If you keep your regular SIM active, configure each line deliberately:

1. Open Settings → Connections → SIM manager and enable the travel eSIM.
2. Under Preferred SIMs or equivalent controls, select it for Mobile data.
3. Keep calls and messages on the regular SIM when appropriate; a data-only travel plan does not replace your usual number.
4. Enable Data roaming for the travel eSIM if its instructions require it.
5. Consider disabling automatic data switching, so the phone does not fall back to the home SIM when the travel line briefly loses service.
6. Turn off data roaming on the regular SIM if you do not intend to use it abroad.
7. After landing, select the travel line, wait for registration and test a simple webpage with Wi-Fi off.

Signal bars alone are not enough: check the mobile-data indicator after a restart. Background activity on the home SIM can still create charges.

Practical travel scenarios

Install at home, activate after arrival. If validity begins on first connection in the destination, install over Wi-Fi at home but leave data on the regular line until landing. Then select the travel eSIM, enable roaming for that line if required and wait for registration.

Activate before departure. This can help during a connection or immediately after landing, but some plans count from installation or activation. Confirm the start rule in the Kaspersky eSIM Store app or website before arranging it.

Keep a home number available. On supported versions, Samsung Galaxy S24 can manage more than one SIM line. Keep the home SIM for calls or verification messages and use the travel eSIM for data. Set calls, messages and data separately.

Cross several countries. Check that the plan covers every country on the route. A connection in one country does not prove validity in the next. Save order details offline and label stored profiles clearly.

Maps, messaging and hotspot. Video calls, streaming, backups and cloud sync can consume data quickly. Disable automatic updates when appropriate. If you use hotspot, check that tethering is allowed and monitor usage.

Troubleshooting eSIM on Samsung Galaxy S24

“Add eSIM” is missing. Recheck Settings → Connections → SIM manager, update and restart. Confirm the model number and sales region. If EID is also missing, contact the seller or carrier before purchase.

The QR code will not scan. Increase brightness, remove glare and use a second screen. Start the scan from SIM manager, not the ordinary camera app. If the code was already used, ask support before repeating installation.

The profile downloads but there is no service. Confirm that the travel eSIM is enabled and selected for data, then enable its data roaming if required. Toggle airplane mode, allow registration time and check destination and validity. Leave network selection automatic unless instructed otherwise.

Apps are offline despite a signal. Check the data SIM and mobile-data icon with Wi-Fi disabled. Use only APN settings supplied for the selected plan. Review data limits, data saver, private DNS or other network settings. Kaspersky eSIM Store helps arrange an eSIM plan; it is not a VPN.

Data uses the wrong SIM. In SIM manager, select the travel eSIM for mobile data, disable automatic switching and turn off roaming on the home SIM if needed. Test with Wi-Fi off.

Activation stops. Check the connection, date and time, storage and whether the profile already appears in SIM manager. Do not factory-reset first. Record the error, model number and software version, keep QR details private and contact support. A deleted profile may not be reinstallable.

FAQ

Can Samsung Galaxy S24 use a physical SIM and eSIM together?

Supported versions can offer nano-SIM plus eSIM combinations, and Samsung documents dual-SIM controls for the S24 Series. Exact behaviour depends on model, software and carrier. Check SIM manager.

Does 5G guarantee that a travel eSIM will work?

No. Access also depends on regional bands, destination network, plan and local availability. A travel eSIM may use 4G LTE instead and still handle ordinary travel tasks.

Can I use eSIM for calls and SMS?

Only if the selected plan includes them and the network supports them. Many travel options are data-only. Use messaging and calling apps over mobile internet when suitable, and keep the regular SIM for your usual number if needed.

Do I need Wi-Fi to install it?

You need an internet connection to download the profile. Wi-Fi is preferable because it avoids using the wrong data line during setup. If the phone has a working connection, Samsung’s flow can use available wireless or mobile data, subject to the plan’s instructions.

What if the phone is carrier-locked?

Ask the carrier about unlocking before buying. An EID and Add eSIM menu cannot remove a network lock, and a plan intended for another network may not activate.

Final device check before your trip

Samsung Galaxy S24 is a suitable eSIM candidate, and current official Samsung information confirms eSIM support for the S24 family. Regional, carrier and software differences still make the on-device check essential. Before paying, confirm Add eSIM, find the EID, check the model number and lock, and review the destination and activation conditions.

When those checks are complete, use the Kaspersky eSIM Store app or website to choose, arrange and activate an eSIM option for mobile internet on the trip. Install over Wi-Fi, select it for data on arrival and enable roaming only for that line when required. Monitor usage and save support details.

Trip eSIM checklist

• [ ] Samsung Galaxy S24 shows an eSIM option in Settings → Connections → SIM manager.
• [ ] The EID and model number have been checked.
• [ ] The phone is unlocked or the carrier has confirmed compatibility.
• [ ] Destination, validity, data allowance and activation start rule are understood.
• [ ] The profile is installed securely over Wi-Fi without deleting a needed eSIM.
• [ ] The travel eSIM is selected for mobile data and its roaming setting is correct.
• [ ] Roaming and automatic switching on the home SIM are controlled.
• [ ] A simple connection test will be made after arrival.

If any item is uncertain, pause before purchase and confirm the handset and plan conditions. This helps avoid paying for an eSIM a regional or carrier-restricted Samsung Galaxy S24 cannot use.
