Samsung Galaxy S23 eSIM: compatibility, setup, and travel use

The Samsung Galaxy S23 supports eSIM on compatible regional versions. Samsung includes the Galaxy S23 in its official Galaxy eSIM device lists, and the phone can use an eSIM alongside a physical nano-SIM where the local model and carrier permit it. However, the name alone cannot confirm every unit: eSIM availability can vary by country of sale, exact model number, software, and carrier restrictions. Before choosing a travel plan, check the actual phone for an EID and an option to add an eSIM.

This guide covers compatibility checks, installation, activation, travel data, and common fixes. The device and plan must both support your intended use.

Samsung Galaxy S23 at a glance

This page covers only the standard Samsung Galaxy S23. S23+, S23 Ultra, and S23 FE are separate models; do not use their compatibility results as proof for this phone.

Does the Samsung Galaxy S23 support eSIM?

Yes, Samsung lists the Galaxy S23 among its eSIM-capable Galaxy devices in supported markets. On a supported phone, you can add a digital SIM profile through the SIM manager, usually by scanning a provider-issued QR code or entering activation details. Mobile service still depends on the profile issuer, destination network, carrier support, and plan conditions.

Samsung notes that eSIM service can vary by country, carrier, and model. A Galaxy S23 bought in one market may show different SIM options from one bought elsewhere; a locked or carrier-branded handset can also be restricted. 5G capability does not prove eSIM support or guarantee 5G access on a travel network.

Check the EID and eSIM controls on your own phone. If present, confirm the phone is unlocked and the travel plan supports it. If the checks disagree, verify the exact model code with Samsung or the original carrier before purchase.

Check compatibility before choosing a plan

Run these checks while you still have time to resolve a restriction:

• [ ] Open Settings → About phone → Status information and look for EID. On some software versions, EID is listed directly under About phone or in Status information.
• [ ] Open Settings → Connections → SIM manager and look for Add eSIM or Add mobile plan. The wording can differ by One UI version, country, and carrier.
• [ ] Make sure the Galaxy S23 is not network-locked. If you are unsure, ask the original carrier whether another provider’s eSIM can be used.
• [ ] Check the exact model number and country of origin in Settings → About phone. Share those details with Samsung support or the seller if the EID or menu is missing.
• [ ] Confirm that the plan covers every country on your itinerary, works with the phone’s supported bands and network setup, and has enough data and validity.
• [ ] Read whether the plan starts when installed, when it first connects in the destination, or on another trigger. Follow the plan’s specific instructions.

Find the EID and the eSIM menu

The device compatibility checklist provides a quick recap of the checks to complete before purchase.

The EID identifies the phone’s embedded SIM hardware. A provider may request it to check eligibility or troubleshoot provisioning. It differs from the IMEI and is not an activation code. Share it only through a trusted support channel when requested.

On most Galaxy S23 versions, start at Settings → About phone → Status information and look for EID. Then open Settings → Connections → SIM manager and check for Add eSIM, Add mobile plan, or a similar control. Labels can vary by One UI version and market. Use Settings rather than a dial code or another model’s screenshot.

If the EID is missing, update and restart the phone, then search Settings for “EID” or “SIM manager.” If both EID and add-eSIM control remain absent, regional or carrier limitations may apply. Ask Samsung or the seller to verify the model code; a factory reset cannot add unsupported hardware capability. If EID appears without an add option, check for a One UI update and ask the carrier about eligibility. If the menu appears without EID, ask Samsung to confirm the model before buying a plan.

Install and activate an eSIM

You need internet access and the plan’s QR code or manual activation details. Display the code on another screen or use the provider’s in-app installation flow if available.

1. Prepare the phone. Connect to reliable Wi-Fi, install any pending system update, and confirm the Galaxy S23 is unlocked and has an Add eSIM option. Keep the physical SIM active until the travel profile is working if you need your usual number.
2. Open SIM manager. Go to Settings → Connections → SIM manager and tap Add eSIM or Add mobile plan.
3. Choose the installation method. Select the option to scan a QR code if offered. Point the camera at the provider’s code. If you received manual details, choose the corresponding option and enter them carefully. Do not publish or forward the activation code.
4. Download the profile. Review the on-screen instructions and confirm the download. Keep Wi-Fi connected and do not close Settings while the profile is being added. The phone may need a minute or two to complete the process.
5. Name the line. Give it a clear label such as “Travel” or the destination name. This makes it easier to select the correct SIM for data and avoid changing the settings for your home line.
6. Choose what the line does. In SIM manager, select the travel eSIM for mobile data when you are ready to use it. Keep calls and texts on your regular line if desired, while checking possible roaming charges with your home carrier. Menu choices vary by region and software.
7. Activate according to the plan. Some profiles become active as soon as installed; others start when they first connect to a supported network or when a stated validity period begins. Follow the plan’s terms rather than turning it on early by assumption.
8. At the destination, connect. Turn on the travel eSIM, select it for mobile data, and enable data roaming for that line only if the plan instructions require it. Allow a short time for registration, then open a webpage to confirm data works.

For Samsung-specific menu guidance, see Android eSIM installation instructions. The iOS eSIM installation instructions are for a different device system, but can help if you are also preparing an iPhone for the trip. Always prioritize the steps shown by the provider of your specific plan, since QR-code, app-based, and manual installation flows can differ.

Use the Galaxy S23 eSIM while travelling

A travel eSIM can provide data for maps, transport, bookings, translation, and messaging. Install it at home over Wi-Fi and leave it off until the plan’s activation timing; installation after arrival requires internet access.

Check every destination and stopover, data allowance, validity, hotspot rules, fair-use terms, and activation trigger. A single-country plan may not include neighboring countries; tethering and top-ups depend on plan terms.

On arrival, select the travel eSIM for mobile data in SIM manager. If your home SIM remains on, check roaming charges and ensure data uses the travel line. Enable roaming for that line only if instructed. Data plans generally do not replace your home number or include voice and SMS; internet calling and messaging apps can use data.

For a multi-country itinerary, check coverage for every leg. The phone may need time to register on a new local network. Keep order details and support information accessible offline. Do not delete a working eSIM unless the provider confirms you can reinstall it; some activation codes are one-time use.

Kaspersky eSIM Store is an app and website where travellers can choose, arrange, and activate an eSIM with a mobile-data plan for an international trip. Once your Samsung Galaxy S23 is confirmed compatible, use it to compare destination plans, data allowance, and validity. Coverage depends on the selected plan and supported networks. Compare a travel eSIM for your route after confirming the phone is compatible.

Troubleshooting: if the eSIM does not install or connect

“Add eSIM” is missing. Recheck the EID, search Settings, install available software updates, and restart the phone. Confirm the exact model code and sales region. If the control remains absent, contact Samsung or the original carrier to check whether eSIM is available for that unit.

The QR code cannot be scanned. Increase screen brightness on the device displaying it, clean the Galaxy S23 camera lens, and keep the entire code in frame. If the camera is displaying the QR on the same phone, use the provider’s manual activation option or display the code on another trusted device. Check whether the code has already been used or expired before requesting a replacement.

The profile download fails. Connect to stable Wi-Fi, disable any temporary VPN that interferes with provisioning, check date and time are automatic, and try again once. Verify that the plan is intended for the destination and for a Samsung device. If the profile was partly added, avoid repeated installation attempts and ask the plan provider how to continue.

The eSIM is installed but there is no data. In SIM manager, confirm that the eSIM is switched on and selected for mobile data. Check that the plan has started, has remaining data, and includes your current country. Follow its instructions for data roaming and APN settings; do not guess an APN. Turn airplane mode on for a few seconds and off again, then restart if necessary.

The phone sees a network but apps stay offline. Verify the mobile-data line, data limit, and roaming setting for the travel eSIM. Turn off automatic switching of mobile data if it routes data through the home SIM. Try a different supported network selection only when the provider’s instructions recommend it. Check whether a VPN, private DNS, or local network condition is affecting traffic.

The eSIM works at home but not abroad. Confirm that the destination is included and that the plan’s activation window has begun. Allow time for network registration, then follow the provider’s supported network selection steps. Coverage depends on the local partner network, location, device bands, and conditions; a 5G icon is not guaranteed. If the plan allows LTE/4G, choosing a supported network mode can help where 5G is unavailable.

The home SIM stopped behaving as expected. In SIM manager, check which line handles calls, messages, and mobile data. Restore the preferred defaults carefully. Ask your home carrier about roaming before leaving that line enabled, and avoid deleting either profile unless you understand the consequences.

If the issue persists, contact the plan provider with model code, software version, destination, and error details. Share the EID only through official support when requested; never post activation details publicly.

Frequently asked questions

Can I use a physical SIM and an eSIM together?

Eligible versions can use physical SIM and eSIM together, but combinations depend on region and software. SIM manager shows which lines can be enabled. Stored profiles and simultaneously active lines are not necessarily the same.

Does a 5G Galaxy S23 automatically have eSIM?

No. 5G capability and eSIM support are separate features. Samsung lists the Galaxy S23 for eSIM in supported markets, but verify your specific unit using its EID and SIM manager, then confirm carrier unlock and plan support.

Can I move the profile to a replacement phone?

Do not assume so. Plans vary: some permit transfer or reissue, while others bind a profile to one device. Check with the provider before changing phones.

Will the travel eSIM give me a local phone number?

A data-only plan does not supply a regular number for calls and SMS unless stated. Messaging and internet calls may work through apps over data.

When should I install it?

Install over stable Wi-Fi and check when validity begins; it may start on installation or first connection. Ask the provider if unclear.

Final device check and trip eSIM

<a id="final-device-check-and-trip-esim"></a>

Before choosing a plan for the trip, confirm that your Samsung Galaxy S23 displays an EID and an Add eSIM option, is not locked in a way that blocks the plan, and is running current software. Check that the exact destination is covered, the validity period fits your itinerary, the data allowance suits your use, and the activation instructions are clear. Save the setup details and support route before departure.

If the phone passes those checks, choose a travel eSIM plan that fits the countries and data needs on your route, then install and activate it according to its terms. If the EID or menu is missing, pause and verify the unit’s region and model code with Samsung or the original carrier before purchase. This small check helps ensure your Galaxy S23 is ready for the mobile data you expect on the journey.
