Samsung Galaxy S20+ 128GB eSIM: compatibility and setup guide

Short answer: Samsung currently lists the Galaxy S20+ among Galaxy models that support eSIM. However, that family-level listing does not guarantee eSIM on every Samsung Galaxy S20+ 128GB. Samsung warns that support can depend on the country of origin. The storage capacity alone does not identify a phone’s regional hardware or firmware. Check this specific unit for an EID and an Add eSIM option before choosing a plan.

That check matters especially for an imported or carrier-issued phone. Two devices with the same retail name can have different model codes, software, SIM configuration, or restrictions. A travel eSIM must also cover your destination and accept your phone’s exact variant. Use the steps below to verify the device and prepare mobile data before a trip.

Samsung Galaxy S20+ 128GB eSIM at a glance

The manufacturer’s current guidance supports a positive answer for some Galaxy S20+ versions, but not a blanket promise for every unit. “Samsung Galaxy S20+ 128GB” gives the family and storage size; it does not tell you the precise model code, country of sale, or whether eSIM is enabled in the installed software. Identify the phone in Settings → About phone and check its SIM Manager directly.

Why regional and carrier versions matter

A model family can be sold in multiple markets. Country of origin may affect hardware, firmware features, or whether the eSIM menu is available. The 128GB storage variant does not override a regional difference. If you are considering an imported phone, verify the individual device rather than assuming it matches one sold in your country.

Carrier-issued phones add another question. A network-locked phone may not accept an eSIM from another provider even when it has eSIM hardware. “Unlocked” is useful, but it is not proof that eSIM is present; a lock cannot be removed by installing a plan, and an unlocked phone cannot gain a feature its variant does not expose. Software updates may also change menus, so use official updates before deciding that the option is missing.

There are two separate compatibility checks: whether this particular phone can install an eSIM, and whether the selected service supports the phone and destination. A carrier or plan’s support in a country does not confirm that every Galaxy S20+ regional model can activate there. If buying used, ask the seller to show the full model code, EID screen, and SIM Manager. A confirmation for another S20 model or another region is not confirmation for this device.

Check your phone before choosing a plan

On many Galaxy phones, open Settings → Connections → SIM manager and look for Add eSIM, Add mobile plan, or similar wording. The exact menu may vary by software and market. If a profile is already installed, the menu may display it instead of a prominent add button.

An EID is the identifier associated with the embedded SIM. On compatible software, entering *#06# in the Phone app may show an EID alongside other device identifiers. You can also check Settings → About phone → Status information or a SIM status screen. Paths and labels vary. An EID is a helpful sign; for a specific plan, also confirm that the phone can open the add-eSIM flow and that the provider accepts its exact model.

Use this checklist before paying:

• [ ] Record the complete model code under Settings → About phone.
• [ ] Check SIM Manager for Add eSIM or an equivalent option.
• [ ] Look for an EID in the device information or identifier screen.
• [ ] Install available official updates, restart, and check again if the option is absent.
• [ ] Confirm the phone is not carrier-locked or restricted from adding another provider’s profile.
• [ ] Confirm support for your exact regional model and travel destination.
• [ ] Read the plan’s coverage, data allowance, validity, start timing, and roaming instructions.
• [ ] Keep Wi‑Fi or another internet connection available during setup.

If both the add option and EID are missing, treat the phone as unverified. Ask Samsung or the seller to confirm eSIM for the full model code and country of origin. Do not buy a plan based only on a product title or general family list. If that regional variant does not support eSIM, use a compatible physical SIM where available or another confirmed-compatible unlocked device.

When contacting support, provide the full model code and software version, and describe which menu items you can see. You usually do not need to post your EID in a public forum; it identifies the embedded SIM and should be shared only through an appropriate support channel if requested. A photo of the SIM Manager screen can help a seller confirm whether the eSIM option is available, but hide personal numbers and other account details. Ask for confirmation that applies to the exact phone in hand, rather than a general statement about the Galaxy S20+ family. Also check that the phone can connect to the intended provider’s network bands and that the travel plan is available for the country you will visit. These checks answer different questions: the first concerns the phone, while the second concerns service availability for your itinerary.

For a quick compatibility check, check your device. Do this before selecting a travel plan so you do not pay for a profile the phone cannot install.

Plan your travel data

A travel eSIM is a digital profile installed on a compatible phone. Plans available through Kaspersky eSIM Store are intended for mobile data; do not expect a separate local phone number, ordinary cellular calls, or SMS unless the terms explicitly say otherwise. Messaging and voice apps can use data with accounts you already have, subject to their own requirements.

Choose a plan by destination, expected use, data allowance, and validity. Maps, translation, transport, bookings, messaging, and browsing use data; video, cloud backups, automatic updates, and hotspot use can consume much more. If your route crosses borders, verify every country is included. A single-country plan does not automatically cover neighbouring destinations.

Check when the plan becomes valid and when data use begins. Conditions can depend on purchase, installation, first connection, or an activation schedule. Follow the instructions for the specific plan rather than assuming all eSIMs start in the same way. If you install before departure, confirm whether the profile should remain off until arrival.

Kaspersky eSIM Store is an app and website where you can choose, arrange, and activate an eSIM with a mobile-data plan for an international trip. It does not make a phone compatible. The English store homepage is a general place to browse current destinations and plan options, not a country-specific tariff: browse destinations and current plan options.

Keep your home SIM available without accidental roaming

If your particular Galaxy S20+ supports the relevant dual-SIM setup, you may be able to manage a physical SIM and eSIM together. Check the options on your phone. Before travel, select the travel eSIM for mobile data and review the defaults for calls and messages separately.

Your home operator may charge for data roaming on its SIM. To reduce that risk, disable mobile data for the home line or make sure the travel eSIM is selected for data. Some travel eSIMs require data roaming to be enabled for that profile; do so only if the provider’s instructions say so. This setting does not replace checking which SIM is selected for mobile data. Automatic data switching, if available, may move traffic to your home SIM when the travel profile loses signal, so review it before leaving.

How to install and activate an eSIM on Samsung Galaxy S20+ 128GB

Have a stable Wi‑Fi connection and the QR code or installation details ready. Check the plan’s activation timing first. A QR code may be single-use; do not delete a working profile or retry installation repeatedly unless the provider says it can be reissued.

1. Confirm compatibility. Check for an EID or eSIM option and confirm the exact regional model is supported by the provider.
2. Update and connect. Install available official software updates, restart, and join reliable Wi‑Fi.
3. Open SIM Manager. Go to Settings → Connections → SIM manager. If the labels differ, search Settings for “SIM manager” or “eSIM.”
4. Choose Add eSIM. Select Add eSIM or the closest option. Choose QR scanning or manual entry according to the instructions you received.
5. Scan or enter details. Use the phone’s eSIM setup flow to scan the provider’s QR code. Enter activation details manually only when supplied by the provider.
6. Wait for download. Keep Wi‑Fi connected and allow a few minutes for the profile to download. Avoid restarting while the phone is processing it.
7. Name the line. Use a clear label such as “Travel data” to distinguish it from your home SIM.
8. Select mobile data. In SIM Manager, choose the travel eSIM for data when you are ready. Check voice and text defaults separately.
9. Review roaming. Enable roaming for the travel profile only if its instructions require it. Make sure the home SIM is not selected for data if you want to avoid its roaming charges.
10. Test on arrival. Turn off Wi‑Fi briefly, wait for a signal, and open a simple webpage. If the plan starts only in its destination, complete the connection there.

See the Android eSIM installation instructions for general setup guidance. The iPhone eSIM installation instructions are for iOS devices and do not apply to this Samsung phone.

Keep the eSIM profile on the phone after installation. Activation codes may not be reusable after deletion or transfer. If you reset or replace the phone, check the provider’s reinstallation process first instead of removing a profile as a troubleshooting shortcut.

Use the eSIM during a trip

After landing, make sure the travel eSIM is enabled and selected for mobile data. Follow the provider’s roaming instructions and allow the phone time to register. Signal and connection time vary with destination, local partner network, and reception. If you see signal but apps cannot connect, check whether mobile data is enabled for the eSIM and review any APN details supplied with the plan.

Keep the home SIM’s data setting under control. Disable automatic data switching if it could move data to the home SIM when the travel eSIM loses signal. Check the home operator’s roaming terms. Two installed profiles do not necessarily mean both can provide data simultaneously; available combinations depend on the device configuration.

For routine use, let maps and messaging use the travel connection and defer large downloads or photo backups to Wi‑Fi. Monitor usage in the plan account and Android settings; the phone’s estimate may differ from the provider’s meter. If using a hotspot, confirm that the plan permits tethering and remember that connected laptops can consume data quickly and drain the battery.

Common travel scenarios

• Install before departure: Add the profile over Wi‑Fi if the plan permits early installation. Keep it labelled, note when validity begins, and leave your normal data line selected until you are ready to use the travel plan.
• Install after arrival: Use an available internet connection and follow the provider’s flow. If the QR code is displayed on the same phone, use an in-app setup or manual entry if offered.
• Cross a border: Check that the next country is included and that the plan remains valid. Allow time for network registration after arrival.
• Need your usual number: Keep the home SIM active if appropriate, but set mobile data to the travel profile. Calls or texts on the home line may incur roaming charges.

Troubleshooting: profile, signal, or data

“Add eSIM” is missing

Check the complete model code, install official updates, restart, and search Settings for eSIM. Look for an EID. If both are absent, the regional variant may not expose eSIM. Ask Samsung or the seller to check the model code and country of origin. A plan provider cannot enable a feature the phone does not support.

The QR code will not scan

Increase the display brightness, clean the camera lens, and hold the code steady. If the code is shown on this same phone, try the provider’s install flow or manual-entry option when available. Confirm that the code is for your order and has not already been used. Ask the provider to check activation details before deleting a profile or requesting a replacement.

The profile downloads but does not activate

Keep Wi‑Fi on until setup finishes. Check automatic date and time, restart once, and follow the plan’s activation timing. A profile may install before it can connect in the covered destination. Contact the provider with the error message if activation still fails.

There is no signal after arrival

Confirm the eSIM line is switched on and selected for data; check that airplane mode is off. Move to a better reception area and wait a few minutes. Verify that the country is covered and the plan is valid. Use manual network selection only if the provider recommends it.

Signal is present but data does not work

Confirm mobile data is enabled for the travel eSIM, not the home SIM. Enable data roaming for that profile only if instructed. Check the plan balance, validity, and any provider-supplied APN settings. Do not guess an APN. Retry a basic webpage after checking the settings.

The wrong SIM appears to use data

Open SIM Manager and explicitly choose the travel eSIM for data. Review automatic data switching and the home line’s roaming settings. If unsure which line is active, temporarily turn off Wi‑Fi and check the status and Android data-usage screens.

The plan works elsewhere but not on this phone

A different Galaxy S20+ does not prove this regional unit is compatible. Compare complete model codes, check the carrier lock and firmware, then give the plan provider the model code, destination, error, and time of the attempt. Share an EID or QR code only through a secure support channel if requested.

Frequently asked questions

Is Samsung Galaxy S20+ 128GB eSIM compatible?

Some Galaxy S20+ versions support eSIM, and Samsung includes the model in its family-level support list. The 128GB label alone does not confirm an individual phone. Check its EID and SIM Manager, then verify the full model code and region.

Does every country’s Galaxy S20+ support eSIM?

No. Samsung warns that support can depend on the country of origin. Check the specific imported or locally sold unit rather than relying on a general series listing.

Does 128GB mean this is the eSIM version?

No. It describes internal storage, not eSIM hardware, regional firmware, or carrier status.

Is an EID enough to guarantee a travel plan will work?

No. It is a useful indicator, but the phone must also expose eSIM setup, be eligible for activation, and be accepted by the provider for the destination.

Can I keep my physical SIM and add an eSIM?

Possibly, depending on the phone’s regional configuration and software. Check SIM Manager. Select the travel eSIM for data and review roaming on the home line.

Does a travel eSIM include a phone number?

Not unless the plan explicitly says so. Plans in Kaspersky eSIM Store are intended for mobile data; internet messaging and calls can use apps and existing accounts.

Should I enable data roaming?

Only as directed for the relevant profile. Some travel plans require roaming on the eSIM. Confirm the instruction and keep the travel profile selected for data.

Can I move the eSIM to another phone?

Do not assume so. Check the provider’s transfer or replacement rules before changing phones, resetting this device, or removing a profile.

What if there is no EID and no add-eSIM option?

Update official software and check again. If both are still missing, treat the phone as unverified and ask Samsung or the seller about its regional model. Use a compatible physical SIM where available or another confirmed-compatible device if that version lacks eSIM.

Final check before your trip

Samsung’s current family-level guidance lists the Galaxy S20+, but its country-of-origin caveat means Samsung Galaxy S20+ 128GB still needs a unit-level check. Confirm the model code, EID, and Add eSIM option; verify the phone is unlocked; then check that the plan covers your destination and follow its validity and roaming instructions.

Once compatibility is confirmed, Kaspersky eSIM Store can help you choose, arrange, and activate an eSIM plan for mobile data on an international trip. Review the plan details before proceeding and keep the installation information available. Checking at home makes it easier to resolve a regional or carrier restriction before you travel.
