Apple iPhone SE 2020 eSIM: compatibility and setup guide

Short answer: Apple’s iPhone SE (2nd generation), commonly searched for as Apple iPhone SE 2020, supports eSIM on compatible regional versions. Apple lists the model’s Dual SIM configuration as one nano‑SIM and one eSIM. That does not mean every unit sold under the same name can use an eSIM: Apple identifies mainland China as an exception for this generation, and carrier or device restrictions can also prevent activation. Check the phone itself before choosing a travel plan.

The key point is to confirm both the hardware and the network conditions. Look for an EID in Settings, check that iOS offers an option to add a cellular plan, and make sure the phone is unlocked if the travel eSIM uses a different provider from your regular SIM. If those checks pass, the iPhone SE 2020 can keep a physical home SIM in place while using an eSIM for mobile data abroad.

At a glance

“Apple iPhone SE 2020” is a commonly used retail name for the iPhone SE (2nd generation), introduced in 2020. Apple’s own support material uses the generation name. This guide is about that second-generation device, not the iPhone SE (3rd generation) or another iPhone. Storage capacity and color do not determine eSIM support; the market version, carrier status, software, and local service availability matter more.

Does Apple iPhone SE 2020 support eSIM?

Yes, for compatible versions. Apple’s technical specifications for iPhone SE (2nd generation) state “Dual SIM (nano-SIM and eSIM).” Apple’s Dual SIM guidance also names this generation as supporting one physical SIM and one eSIM. This is enough to establish that eSIM is a real capability of the model, rather than a feature inferred from another iPhone.

There are important qualifications. Apple says eSIM is not available in every country or region, not every carrier supports it, and eSIM use may be disabled on an iPhone purchased from some carriers. Its current guidance for mainland China lists only specified newer iPhone models as supporting eSIM; the 2020 SE is not among them. A mainland China-market unit should therefore be treated as lacking eSIM, even if a seller describes it simply as “iPhone SE 2020.”

The regional picture needs a little care. Apple’s guidance for Hong Kong and Macao describes certain iPhone models with two physical nano‑SIMs, but also explicitly directs owners of iPhone SE (2nd generation) in those markets to its eSIM instructions. The exact configuration can depend on the device’s market and model number. Do not conclude from a listing, SIM tray, or country name alone. For a second-hand or imported phone, the device’s own EID and Settings screen are the practical checks.

A carrier-locked phone is a separate issue from eSIM hardware. An eSIM-capable iPhone can still refuse a plan from another provider if it is locked to its original carrier. The issuer of the travel plan must also permit eSIM activation for that device and destination. So the accurate answer is: the model family supports eSIM, but an individual handset must pass the regional, EID, carrier-lock, and plan checks below.

Regional versions and carrier restrictions

Regional differences are most relevant when a phone was bought outside the country where you plan to use it. A device sold for mainland China should not be assumed to have an eSIM simply because another country’s iPhone SE 2020 does. Hong Kong and Macao have distinct Apple SIM guidance, and the SIM configuration of a handset may not match an international retail version. A marketplace description may omit the original sales region, use a generic model title, or confuse the second and third generations.

The model number helps identify the hardware family, but it does not replace the live Settings checks. On the iPhone, open Settings → General → About and tap the part-number entry if needed to show the model number beginning with “A.” If you are considering a used device, ask the seller for the original region, model number, and a view of the EID field with the identifier covered. Never ask a seller to post an unmasked EID publicly; it is a device identifier and does not need to be shared to establish compatibility.

Then check the carrier lock. In Settings → General → About, find Carrier Lock (wording can vary slightly by iOS version). “No SIM restrictions” indicates that the phone is unlocked. If a carrier name or restriction appears, contact that carrier and ask whether it can unlock the phone for use with a different eSIM provider. A local plan and your current SIM can be from different providers only when the lock and plan terms allow it.

A software update can change menu labels or fix setup issues, but it cannot add eSIM hardware to a version that lacks it. If you cannot find an EID or eSIM option after updating, do not buy a plan on the assumption that an update will enable it. Verify the exact variant with Apple or the seller and use a different compatible device if the handset is not eSIM-ready.

Check compatibility on the phone before buying

Use this checklist on the exact Apple iPhone SE 2020 you will take on the trip:

• Find the EID. Open Settings → General → About and scroll through the device information. A compatible eSIM device normally shows an EID, a long embedded-SIM identifier. You can also use Settings search for “EID.” Record only whether the field exists; do not post the number publicly.
• Look for the add-plan control. Open Settings → Cellular (called Mobile Data in some regions or languages). Look for Add eSIM, Add Cellular Plan, or a similar option. The exact label changes with iOS version and locale.
• Check carrier lock status. In Settings → General → About, look for Carrier Lock. Confirm with the original carrier if it is not marked “No SIM restrictions.”
• Confirm the generation and original market. Verify that it is the iPhone SE (2nd generation), not another SE generation, and ask whether it was sold for mainland China, Hong Kong, Macao, or another market if the origin is unclear.
• Check the plan conditions. Make sure the eSIM plan covers the country or region on your itinerary, works with an unlocked iPhone, and fits the length and data needs of the trip.
• Keep a working internet connection for setup. Wi‑Fi is useful when downloading a profile, especially before departure.

If both the EID and the add-eSIM control are present, that is a strong on-device indication that the phone can install an eSIM. It does not guarantee that every provider or plan will activate: carrier lock, service restrictions, network availability, and the eSIM issuer still matter. If the EID is missing or the add-plan option is unavailable, pause and verify the variant before purchase.

Check whether your device is compatible before selecting a travel plan. Compatibility checks are especially useful for imported and refurbished phones, where the original market may not be obvious from the box or listing.

How to install and activate an eSIM on Apple iPhone SE 2020

Install the profile over stable Wi‑Fi and follow the selected plan’s instructions. A provider may supply a QR code, app flow, link, or manual details. Installing a profile and starting its validity period are not always the same event, so check the plan terms.

1. Check readiness: confirm EID and Add eSIM, update iOS if needed, and verify Carrier Lock says “No SIM restrictions” when using a different provider.
2. Open Settings: go to Settings → Cellular or Mobile Data and tap Add eSIM or Add Cellular Plan.
3. Add the profile: choose Use QR Code and scan the issuer’s code on another screen, or use its supported app, link, or manual option. Enter any confirmation code exactly as supplied.
4. Label the lines: use clear labels such as “Home” and “Travel” so you can identify each line in Cellular settings.
5. Choose when to use it: follow the plan’s activation rules. If it should start at your destination, leave the home line selected for data until arrival.
6. Select data at destination: turn on the travel line and choose it under Settings → Cellular → Cellular Data. Enable Data Roaming for this eSIM only if the plan instructions require it.
7. Test: turn Wi‑Fi off briefly and open a page or app. If it fails, check the settings below before deleting the profile.

For a visual walkthrough, see the iOS eSIM installation instructions. The Android installation instructions are for readers setting up another device; Android menu names differ by manufacturer.

This generation’s supported Dual SIM setup is one physical SIM and one eSIM, not two active eSIMs. Do not delete an installed profile during troubleshooting until the issuer confirms it can be reinstalled; activation codes may be single-use.

Using the eSIM for mobile data on a trip

Before departure, compare the plan’s coverage area with every country on your itinerary, including stopovers. A plan labelled for a region may cover several places, while a single-country plan may not work after crossing a border. Check the included data amount, validity period, supported network conditions, and any rules for activation or tethering. Plan details can change, so use the current terms shown at checkout rather than relying on an old screenshot or recommendation.

When you land, select the travel eSIM as the cellular-data line. Keep your home SIM active only if you need its number for calls or messages and understand its roaming charges. An internet-only travel eSIM generally does not provide a regular phone number, standard voice calls, or SMS unless the selected plan says otherwise. Internet calling and messaging apps can work over data, subject to the app and account settings.

Data roaming is not a universal switch that should always be on or always off. Some travel eSIMs need it enabled to connect to a partner network; others may give different instructions. Follow the selected plan’s setup steps, and check that roaming is disabled on the home line if you want to avoid unexpected charges. With Dual SIM, the iPhone uses one cellular data line at a time. Review Settings → Cellular → Cellular Data and turn off Allow Cellular Data Switching if you do not want the phone to change to the other line automatically.

Three common travel setups illustrate the choices:

Kaspersky eSIM Store is an app and website where you can choose, arrange, and activate an eSIM with a plan for mobile data during an overseas trip. It is intended to help prepare travel data use; it is not a replacement for checking your device, the plan’s coverage, or the service terms. The eSIM profiles and connectivity depend on the plan and networks available in the destination.

Troubleshooting: when the eSIM does not connect

Keep the eSIM profile installed while troubleshooting. Removing it may require the issuer to provide a new activation code.

No Add eSIM option: Confirm the generation, then check Settings → General → About for an EID. Restart and update iOS if appropriate. If both EID and Add eSIM are missing, verify the original market version with Apple or the seller before buying a plan.

QR code will not scan: Increase screen brightness, clean the camera lens, and hold the code steady on another device. Confirm that the code belongs to this plan and has not already been used. Follow the issuer’s instructions if it supplied an app, link, or manual activation details instead.

Profile installed, but No Service: Verify that the plan covers your current country, the travel line is turned on, and the phone is unlocked if required. Toggle Airplane Mode, restart, and allow time for registration. If the issuer recommends manual network selection, follow its directions rather than guessing.

Signal but no internet: In Settings → Cellular → Cellular Data, select the travel line and turn on Cellular Data. Enable Data Roaming for that eSIM only if its instructions require it. Check remaining data and validity in the service account, then test with Wi‑Fi off.

Unexpected home-line data use: Recheck Cellular Data and disable Allow Cellular Data Switching if you want to prevent automatic switching. Check the home carrier’s roaming terms separately; installing a travel profile does not automatically prevent the iPhone from using its regular line.

Activation error or a slow connection: Confirm the activation code is correct and unused, the phone has internet access, and the plan is active for this destination. Allow a few minutes after arrival, then restart or toggle Airplane Mode. Contact the plan issuer with the model, iOS version, destination, and error message. Do not share your EID or QR code publicly.

Frequently asked questions

Can I use an eSIM and a physical SIM at the same time?

Yes, on compatible versions. Apple lists Dual SIM on this generation as one nano‑SIM plus one eSIM. Both lines can be configured, but only one line is used for mobile data at a time.

Can Apple iPhone SE 2020 use two eSIMs at once?

No. Apple lists two active eSIM support for later models. This generation’s supported Dual SIM combination uses one physical SIM and one eSIM.

Does every iPhone SE 2020 support eSIM?

No. Regional hardware and carrier restrictions matter. Apple’s current mainland China guidance excludes the iPhone SE (2nd generation). Check the EID, Add eSIM option, original market, and carrier lock on the exact handset.

Will a locked phone accept a travel eSIM?

Not necessarily. Check Carrier Lock in Settings → General → About. If it does not say “No SIM restrictions,” ask the original carrier whether the device can be unlocked before using another provider’s plan.

Must I install the eSIM before travelling?

A profile can often be installed over Wi‑Fi in advance, but the start of plan validity depends on its terms. Follow the issuer’s activation instructions and keep the home line selected for data until the travel plan should be used.

Does a travel eSIM include a phone number?

Many travel plans are data-only, without a regular number, calls, or SMS. Check the selected plan’s terms; calling and messaging apps may use the internet.

What if I cannot find an EID?

Check Settings → General → About on the correct phone. If there is still no EID or Add eSIM option, do not assume that an update or QR code will enable eSIM. Verify the regional variant, or use another compatible device.

Final check before choosing a travel eSIM

For Apple iPhone SE 2020, the general answer is yes: Apple documents eSIM support for compatible iPhone SE (2nd generation) units as Dual SIM with nano‑SIM and eSIM. But an individual phone still needs the right regional hardware, an available EID and Add eSIM control, carrier unlock where required, and a plan that works in the destination. Mainland China versions should be treated as unsupported for eSIM; Hong Kong and Macao configurations need a device-level check because regional SIM arrangements differ.

Before paying, check the EID and eSIM setting on your own handset, confirm that it is unlocked, and verify the plan’s country coverage, data allowance, validity, and activation instructions. If everything matches, the travel profile can handle mobile data while your regular SIM remains available according to your carrier’s terms. To review current destinations and plan conditions, visit the Kaspersky eSIM Store and choose a plan for your trip.
