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

The Samsung Galaxy S23+ supports eSIM in many markets, and Samsung lists the S23+ among Galaxy devices that can use an embedded SIM. That is a model-family answer, not a guarantee for every handset sold under this name. Samsung also cautions that eSIM may not be supported depending on a device’s country of origin. Your specific phone’s settings, exact model code, software, and carrier status determine whether you can add a profile.

Quick answer: check Settings → Connections → SIM manager for Add eSIM, and check the phone’s EID in Settings → About phone → Status information (menu wording may vary). If the option is present and an EID is shown, the handset has the key eSIM capability indicators. Before paying for a travel plan, also confirm the phone is unlocked and that the plan supports your device and destination.

Samsung Galaxy S23+ eSIM at a glance

Samsung’s support pages for the United States, Canada, and other markets currently include the Galaxy S23+ in their supported Galaxy eSIM family. The Galaxy S23-series user manual also documents adding an eSIM through SIM manager and scanning a QR code. These are useful official confirmations of the feature on supported configurations. They do not establish that every regional or carrier-issued unit has the same capability. Samsung’s regional support pages can differ in their device and carrier lists, and its warning about country of origin applies here.

The exact phrase “Samsung Galaxy S23+” does not identify one universal radio and SIM configuration. Retail listings may refer to different model codes, single-SIM or dual-SIM arrangements, firmware builds, and markets. A physical SIM tray alone does not prove that eSIM is absent; conversely, seeing “S23+” on the startup screen does not prove that eSIM is enabled on the particular unit. Use the phone’s own eSIM settings and EID as practical checks, and ask the seller or carrier to confirm the model code if the menu is missing.

Does Samsung Galaxy S23+ support eSIM?

Usually, yes, when the regional variant has eSIM enabled. Samsung lists the S23+ in its current Galaxy eSIM guidance, and the S23-series manual documents profile installation. Samsung also cautions that eSIM may depend on a device’s country of origin. This is a model-family confirmation, not a guarantee for every handset.

Retail listings may cover different model codes, SIM arrangements, firmware, and markets. A physical SIM tray does not prove eSIM is absent, and the “S23+” name alone does not prove it is enabled. eSIM is a regional configuration feature that an update cannot always add. Carrier-branded devices may also have provisioning restrictions or a network lock. Check your own phone, then ask the seller or original carrier about its model code, origin, and lock status.

Keep three questions separate: does this phone have eSIM capability, is it unlocked and eligible for the intended provider, and does the plan cover your destination? A country’s eSIM availability does not guarantee every local carrier supports your account or that every regional S23+ can use it. No exact Samsung model code or operator market was supplied here, so this guide makes no assumption about a particular SKU.

Check your exact phone before buying

Use both the settings menu and the EID check. The EID is the identifier associated with an eSIM-capable device; it is not your phone number, IMEI, or activation QR code. Do not post it publicly or send it to an unknown seller.

1. Open the SIM settings. Go to Settings → Connections → SIM manager. Look for Add eSIM or an eSIM section. On some versions, an option may appear as Add mobile plan or similar.
2. Check for an EID. Open Settings → About phone → Status information and look for EID. Some software versions show it under a different status or SIM-information screen. You can also use Settings search for “EID.”
3. Compare what you find. An EID plus an Add eSIM control is a strong practical indication that the phone can install a profile. If one is absent, do not assume a plan will work: confirm the exact model code and regional status with Samsung or the seller.
4. Confirm the carrier lock. Ask the original carrier or seller whether the device is network-unlocked and allowed to use a third-party eSIM. Do not rely on the presence of a SIM tray or on a successful connection to your current carrier as proof.
5. Check the intended plan. Verify the destination, supported device requirements, data allowance, validity period, activation conditions, and whether the plan starts on installation or first network connection.

Compatibility checklist

• [ ] The SIM manager offers Add eSIM.
• [ ] An EID appears in the phone’s status information.
• [ ] The exact Galaxy S23+ is network-unlocked or confirmed eligible by its carrier.
• [ ] The phone is running supported software and can connect to Wi-Fi during installation.
• [ ] The eSIM plan covers the countries or regions on your itinerary.
• [ ] The plan’s data amount, validity, activation timing, and device rules fit your trip.

Check whether your device is compatible before selecting a travel plan. If the menu and EID checks disagree, pause and ask Samsung or the seller to identify the variant by model code. If your S23+ does not support eSIM, alternatives include using a physical SIM that fits the device, arranging roaming with your existing carrier, or using Wi-Fi where practical. These options have different coverage, cost, and convenience conditions, so check the details before departure.

How to install and activate an eSIM on Samsung Galaxy S23+

Install while connected to reliable Wi-Fi. Keep the QR code on another screen or printed; the phone cannot scan a code displayed only on itself unless the issuer supports manual entry. Do not delete a profile during troubleshooting unless the issuer confirms it can be downloaded again.

QR-code installation

1. Open Settings → Connections → SIM manager.
2. Tap Add eSIM and choose Scan QR code. Use carrier discovery only if the plan issuer supports it.
3. Scan the supplied code, review the details, and confirm the download while online. If scanning is unavailable, use only an issuer-documented manual method.
4. When installation finishes, check that the profile appears in SIM manager. Give it a recognizable label such as “Travel data.”
5. Choose the SIM for mobile data. You can keep your regular line for calls or messages if needed, but review its roaming settings.
6. Follow the plan’s activation instructions. Installation and activation may be separate, and validity may begin at different points.
7. At the destination, enable the eSIM line and select it for data. Enable data roaming for that profile only if the plan requires it. Test a basic web page.

Samsung’s S23-series manual gives the route Settings → Connections → SIM manager → Add eSIM → Scan QR code and notes that a restart may be needed. Menu names vary by software. See How to install an eSIM on Android for the Samsung-oriented store steps. The iOS installation guide is for iPhone users setting up another device; its steps do not apply to this Samsung phone.

Before and after activation

Check that the QR code matches your order and has not already been installed; some codes are single-use or device-bound. Keep the confirmation until service works, and do not share the code. After installation, check that the eSIM is enabled and selected for data. Review any prompt about automatic data switching, since the phone could return to your home SIM and incur roaming charges.

A travel plan is not automatically a second voice line. Many are data-only and do not include a regular number, SMS, or cellular calls. Check the plan terms; internet-based calling and messaging apps can use data, subject to their requirements.

Using the eSIM for mobile data on a trip

A travel eSIM can provide mobile data for maps, messaging, ride bookings, translation, and travel updates. Match its coverage to every country on your route, then check data allowance, validity, activation timing, and any device or roaming conditions. Country-specific and regional plans may cover different places.

Kaspersky eSIM Store’s app and website let you choose a destination and review available eSIM plans for mobile internet during an overseas trip. The service is not a mobile network operator; the available service depends on the selected plan, the phone, and local network conditions.

A practical sequence:

• At home: verify that this S23+ has eSIM and is unlocked. Read activation rules and save the QR code.
• Before departure: install only when instructions allow it. Confirm when validity begins. Review roaming settings for your usual SIM.
• After arrival: enable the travel line, select it for mobile data, and enable data roaming only if required by the plan. Test a web page or map.
• During the trip: monitor usage and validity. Use Wi-Fi for large downloads if you want to conserve data.
• On return: switch data back to your preferred SIM. Keep or remove the profile according to its provider’s reuse rules.

Calls, SMS, hotspot use, and roaming are not automatically included. Check plan terms, and remember that your home carrier may charge for its own roaming. Before boarding, test the SIM settings while you still have reliable Wi-Fi.

Common problems and what to check

“Add eSIM” is missing

Check Settings → Connections → SIM manager and status information for an EID. Confirm the model code and country of origin; Samsung says availability may depend on origin. Install available system updates and restart. If both indicators remain absent, ask Samsung or the seller before buying a profile.

The QR code will not scan

Increase screen brightness on the device displaying the QR code, clean the camera lens, and avoid glare or reflections. Ensure the entire code fits in the frame and that the phone has a reliable internet connection. If the code is on the S23+ itself, display it on another device or use the provider’s documented manual entry method. Ask the plan issuer whether the code is valid, unused, and intended for this device; do not repeatedly reset the phone or delete profiles.

The profile downloads but does not connect

Verify that the eSIM is enabled, selected for mobile data, and allowed to register in the current location under the plan terms. Turn Airplane mode on briefly and off, then restart if needed. Check that mobile data is enabled for the selected line and that any required roaming setting applies to that line. Confirm destination coverage and activation timing with the plan details. If the provider instructs you to choose a network manually, follow that instruction; otherwise, leave network selection automatic.

Mobile data appears to use the wrong SIM

Open SIM manager and review Preferred SIMs or the mobile-data selection. Confirm that the travel profile is selected for data and that automatic data switching will not move traffic back to your home SIM. When two SIMs are enabled, calls and messages can use a different line from data. Watch for a home-carrier roaming indicator and consult that carrier if you are unsure about billing.

Activation says the code is invalid or already used

Check that the QR code belongs to the correct order and that it has not been installed previously. Some providers do not allow reinstallation after deleting a profile, while others can issue a replacement. Contact the plan issuer with the purchase reference and error wording. Avoid posting the QR code, EID, or activation details in a public forum.

Data works intermittently or is slower than expected

Move to a location with a better signal, toggle Airplane mode once, and confirm that the selected network and plan cover that destination. Data performance can vary with local reception, congestion, indoor conditions, and the plan’s network arrangements. A 5G logo is not a guarantee of 5G access: the local network, plan, coverage, settings, and device configuration all matter. If service stays unavailable, contact the eSIM plan’s support channel and provide the phone model code, destination, and relevant error message without exposing private activation credentials.

The phone is locked or carrier restrictions appear

A network lock is controlled by the original carrier. Contact that carrier to ask whether the handset can be unlocked and whether third-party eSIM profiles are allowed. Installing a software update or resetting network settings does not remove a carrier lock. Do not buy a travel plan until you know the restriction is resolved or the carrier confirms eligibility.

Frequently asked questions

Is eSIM available on every Samsung Galaxy S23+?

No. Samsung lists the model family but says country of origin can affect support. Check Add eSIM and the EID, then confirm unlock and provider eligibility.

Does a physical SIM tray mean eSIM is unavailable?

No. A physical tray can coexist with eSIM. Check SIM manager and the EID; supported SIM combinations vary by configuration.

What is the difference between EID and IMEI?

The EID identifies the eSIM component for profile provisioning. The IMEI identifies cellular equipment. Neither is your phone number; do not share these identifiers publicly.

Can I install the eSIM before travelling?

Often, if the plan allows it. Validity may start at installation, activation, or first connection. Read the plan’s rules before scanning the QR code.

Will my regular number still work?

It may, if your home SIM remains active and the configuration supports it. Set calls, messages, and data separately, and check possible home-carrier roaming charges.

Does a travel data eSIM include calls and SMS?

Not necessarily. Many plans provide data only. Check the exact plan; internet calling apps use data and are not a cellular number or SMS service.

Can one eSIM cover several countries, and should I delete it later?

Coverage depends on the plan, so verify every stop. Follow its reuse instructions before deleting a profile; a removed eSIM may not be downloadable again.

Final check: confirm the phone, then choose a trip plan

For the Samsung Galaxy S23+, the manufacturer confirms eSIM support for the model family, with an important regional qualification: the phone’s country of origin and exact configuration can affect availability. Before you buy, look for Add eSIM in SIM manager, check for an EID, verify the exact model code, and confirm that the handset is unlocked. If those checks do not agree, ask Samsung or the seller to verify the device rather than relying on a generic model listing.

Once compatibility is clear, match the eSIM plan to your destination and route, then compare its data allowance, validity, and activation rules. Kaspersky eSIM Store’s website is a place to browse available destinations and review current plans for mobile data during an overseas trip; it is not a country-specific tariff page. Complete setup over a reliable connection, select the intended data SIM, and keep your usual line’s roaming settings in view. This sequence helps you prepare the Samsung Galaxy S23+ for travel while avoiding assumptions about regional support, activation timing, or plan coverage.
