Samsung Galaxy S23+ 8GB RAM eSIM: compatibility and setup

Short answer: Samsung lists the Galaxy S23+ among Galaxy devices that support eSIM, and an official Samsung product specification for an 8 GB Galaxy S23+ variant lists “Embedded-SIM” and “SIM 1 + SIM 2 or Embedded SIM.” That is strong evidence that the model family includes eSIM-capable versions. It does not prove that every phone sold as Samsung Galaxy S23+ 8GB RAM has eSIM enabled: Samsung cautions that availability can depend on the country of origin, and the task name does not identify a sales region, exact model code, carrier firmware, or storage configuration. Check the individual phone before buying or installing a plan.

This guide explains how to verify the actual handset, add an eSIM, and use it for mobile data while travelling. The decisive checks are the EID and the eSIM controls in Settings. If those are missing, contact Samsung or the seller with the model code before relying on the phone abroad.

What the name tells you—and what it doesn’t

“8GB RAM” is a memory configuration, not a complete regional model identifier. Samsung sells Galaxy phones in market-specific configurations; the product code, supported network bands, SIM tray, software build and carrier provisioning can vary. A store listing can also shorten or omit the model code. Consequently, two phones described with the same retail name and RAM amount may not have identical SIM features or network behavior.

Samsung’s current Galaxy eSIM support information includes Galaxy S23+, while Samsung’s published specifications for a representative 8 GB Galaxy S23+ variant identify Embedded-SIM as an option. Samsung’s own regional guidance adds an important qualification: a listed phone may not support eSIM depending on its country of origin. For the exact device in your hand, use the system settings and its model code as the final check; do not rely on the RAM label, the product family name, or a seller’s generic compatibility table alone.

Check compatibility before choosing a plan

Run these checks while connected to Wi-Fi and before paying for a travel data plan. The device compatibility check is a useful starting point, but it cannot replace checking the settings on a regional handset.

• [ ] Open Settings > Connections > SIM manager. Look for Add eSIM or an equivalent option. Menu names can vary slightly with One UI version and language.
• [ ] Open Settings > About phone > Status information and look for an EID. On some software versions, EID appears under About phone directly. You can also try entering *#06# in the Phone app; supported devices may show an EID alongside the IMEI. Do not share either identifier publicly.
• [ ] Compare the model number in Settings > About phone with the box and invoice. The full code helps distinguish regional and carrier variants within the Galaxy S23+ family.
• [ ] Confirm that the handset is unlocked for use with another provider’s eSIM. A device can have eSIM hardware while a carrier restriction prevents activation of a different provider’s plan.
• [ ] Check that Android and One UI are up to date, then restart the phone and check SIM Manager again if the option is absent.
• [ ] Check that the destination and device are accepted by the plan, and that the plan is intended for mobile data if data is all you need.

An EID is a strong sign that the phone has an embedded SIM component, but it is not by itself a guarantee that a particular carrier or travel plan will activate. Conversely, a missing menu can reflect a market-specific software configuration, an outdated build, device management restrictions, or a model that does not expose eSIM in that region. If both EID and Add eSIM are absent after an update and restart, treat compatibility as unconfirmed. Ask Samsung support to check the full model code and country of sale, and ask the seller or carrier to confirm any lock status.

Do not reset the phone just to make the eSIM menu appear. A factory reset deletes personal data and does not add unsupported hardware or remove a carrier restriction. If a seller claims that a particular S23+ supports eSIM, request confirmation for the exact model code and country version, not only the Galaxy S23+ name.

Prepare the phone and plan

Before installation, make sure you have a stable internet connection, enough battery, and access to the QR code or manual activation details supplied after purchase. Some providers allow the profile to be installed before departure and activated later; others start a validity period when you install, connect, or first use the plan. Check the specific plan instructions so you do not start its validity earlier than intended. Treat the installation QR code as private: it may be one-time use and can contain information needed to download your profile.

A travel eSIM for mobile data can coexist with a physical SIM on compatible Galaxy S23+ versions, but SIM capabilities and active combinations may differ by regional configuration. Decide which line should handle mobile data, calls, and messages. If your home SIM remains active, check its roaming terms to avoid unwanted charges. Data roaming may need to be enabled for the travel eSIM itself, depending on the profile instructions; that setting is separate from the roaming setting for your primary SIM.

Add an eSIM to Samsung Galaxy S23+ 8GB RAM

The labels below follow Samsung’s current Galaxy SIM Manager flow. Your exact menu text may differ by region, software version, or provider. Keep the QR code available on another screen or printed page; a phone generally cannot scan a QR code displayed only on its own screen.

1. Connect to Wi-Fi. Keep the phone online throughout profile download. If you received a QR code by email, open it on a computer or another device. Do not scan a code from an untrusted message.
2. Open SIM Manager. Go to Settings > Connections > SIM manager.
3. Choose Add eSIM. Depending on the software build, the option may say Add mobile plan or appear under a similarly named mobile-network setting. If no add option is present, return to the compatibility checks instead of continuing with an assumed setup.
4. Download the profile. Select Scan QR code and point the camera at the provider’s activation code. If the provider supplied manual details, choose the manual entry option and enter them exactly as provided. Some plans can be installed through an app; follow its on-screen flow.
5. Confirm and wait. Accept the prompt to add the mobile plan. Keep Wi-Fi on while the phone downloads and saves the eSIM. Do not close the process or delete the profile if it appears to pause; check the connection and provider instructions first.
6. Name the line. Give it a recognizable label such as “Travel data” so it is easy to distinguish from your home SIM. Labels are for your convenience and do not change the plan.
7. Choose what each line does. In SIM Manager, select the eSIM for Mobile data when you want to use the travel plan. Keep your usual line selected for calls or SMS if appropriate, and review the home carrier’s roaming charges before leaving it enabled.
8. Set data roaming only if instructed. Some travel eSIM profiles require Data roaming to be on for that eSIM to connect abroad. Go to Settings > Connections > Mobile networks and check the setting for the travel profile. Follow the plan’s instructions; enabling roaming for a line can have billing consequences depending on the provider.
9. Check the APN if data does not work. Most profiles configure it automatically. If the plan’s instructions provide an Access Point Name, open Access Point Names for the eSIM and enter only the supplied value, then save and select it. Do not copy APN settings from an unrelated plan.
10. Test at the right time. Installation and activation are not always the same event. If the plan is meant to start on arrival, leave the profile installed but follow its stated activation rules. Once you are in the destination and the plan is active, select the eSIM for mobile data and test a webpage with Wi-Fi turned off.

For additional screenshots and the provider’s Samsung-oriented steps, see Android eSIM installation instructions. The iOS installation instructions are useful only when setting up a separate Apple device; iPhone menus do not apply to the Galaxy S23+.

Kaspersky eSIM Store is an app and website where travellers can choose, arrange, and activate an eSIM with a mobile data plan for an overseas trip. After confirming compatibility, you can browse the Kaspersky eSIM Store to check the current destinations and plan details. Availability, coverage, data allowance, validity, and activation conditions depend on the selected plan and local network arrangements; review them before checkout.

Use the eSIM during a trip

A practical setup is to install the travel profile before departure while on reliable Wi-Fi, then select it for mobile data when the plan is supposed to begin. Before travel, verify the destination list, start conditions, validity period, data amount, tethering rules if you plan to use a hotspot, and whether the plan covers one country or multiple countries. If a route crosses borders, a plan for one country may stop working outside that area even if the phone itself is compatible.

At the destination, open SIM Manager and confirm that the eSIM is turned on and selected for mobile data. Turn off Wi-Fi briefly to check whether mobile data works. If the phone shows signal but apps cannot connect, check that Airplane mode is off, mobile data is enabled, the right line is selected, and any required data-roaming option is enabled for the travel eSIM. Wait a few minutes after arriving; a device may need time to register on a local network. Use automatic network selection first unless the plan’s instructions tell you otherwise.

Keep your original SIM profile installed if you need it, but set the travel eSIM as the data line while abroad when appropriate. Disable mobile data switching between lines if your phone offers that control and you want to avoid the home line using data unexpectedly. Review your home provider’s roaming policy before enabling its line. When the trip ends, switch mobile data back to your normal SIM and turn off or remove the travel profile according to its instructions. Do not delete an eSIM while travelling unless you are sure it can be reinstalled; many activation codes are single-use.

If eSIM setup or mobile data fails

Start with the simplest checks and change one setting at a time. The most common causes are an unsupported regional variant, a carrier lock, a profile that has not finished downloading, the wrong data line, or a plan that is not active in the current destination.

If the menu or EID is missing, troubleshooting a QR code will not solve the underlying compatibility question. Do not repeatedly scan a one-time code. Keep the order details and model code ready when contacting the provider or Samsung, but do not include the QR code or full device identifiers in a public forum.

FAQ

Does Samsung Galaxy S23+ 8GB RAM support eSIM?

Samsung includes Galaxy S23+ in its supported-device guidance, and an official specification page for an 8 GB regional version lists Embedded-SIM. However, “8GB RAM” alone does not identify the regional SKU. Samsung says eSIM can depend on the phone’s country of origin. Confirm Add eSIM and an EID on the exact phone before purchasing a plan.

Does every Galaxy S23+ sold worldwide have the same eSIM feature?

No universal claim is safe. Samsung warns that an otherwise listed model may not support eSIM in some countries of origin. Carrier-branded firmware, regional SIM configurations and device locks can also affect what appears in Settings or whether a profile activates. Verify the specific phone and the service provider’s requirements.

How do I find the EID?

Look under Settings > About phone > Status information or directly under About phone, depending on software. You can also try *#06#; a supported device may display the EID with the IMEI. The EID is not the same as an IMEI, and you should keep both private.

Can I install the eSIM before I travel?

Often, yes, if the plan supports advance installation and you have Wi-Fi. But installation may trigger validity for some plans. Read the activation and validity terms before adding it, and do not assume that downloading the profile means the service starts only on arrival.

Can the Galaxy S23+ use my physical SIM and an eSIM together?

Samsung’s regional specification describes a configuration of SIM 1 + SIM 2 or Embedded SIM for a representative version. The combinations and number of simultaneously active lines can vary by region and software. Check SIM Manager on your handset and review how the intended plan handles dual-SIM use.

Does a travel eSIM include calls and text messages?

Treat it as a mobile-data plan unless its specific terms explicitly include voice or SMS. Internet messaging and calls through apps can use the data connection, while normal calls and texts depend on your other mobile line.

Will eSIM guarantee 5G in another country?

No. The phone’s regional bands, local network availability, plan restrictions and carrier provisioning all affect the connection. eSIM compatibility means the profile can be provisioned; it does not promise a certain network technology, signal level or speed.

What if the phone has an EID but no Add eSIM button?

Restart after installing available software updates and check SIM Manager again. If the control remains missing, have Samsung confirm whether eSIM is enabled for that exact model code and country version. A carrier lock or local firmware policy may also require a check with the seller or carrier.

Final check before your trip

For Samsung Galaxy S23+ 8GB RAM, the model family has official eSIM support and Samsung specifications for an 8 GB version show Embedded-SIM. The final answer for an individual handset still depends on its exact regional version and service status. Before paying for a travel plan, find the EID, look for Add eSIM, confirm that the device is unlocked, and check that the plan supports your destination and activation timing.

Once those checks pass, choose a data plan that fits the route and your likely usage, install it over Wi-Fi, and keep its QR code and account details private. If compatibility remains unclear, resolve it with the seller or Samsung using the full model code first. Then use Kaspersky eSIM Store’s app or website to review current travel destinations and plan conditions, and activate the profile according to the instructions for your particular phone and trip.
