Huawei Mate 40 Pro eSIM: compatibility, setup and travel use

The Huawei Mate 40 Pro can support eSIM, but the answer depends on the exact phone. Huawei's support documentation lists the Mate 40 Pro single-SIM and dual-SIM 8 GB + 256 GB configurations as applicable eSIM products. It also says that availability can vary by device, network provider, country and region. The model name alone is therefore not enough to approve a purchase: the EID and eSIM controls on your own phone are the practical confirmation.

For a trip, a compatible Huawei Mate 40 Pro can use a travel eSIM for mobile data while your regular physical SIM remains available, subject to the phone version and plan conditions. A regional or operator-specific version without an EID will not gain eSIM capability from a QR code. Check the phone before choosing a tariff, and keep the activation details secure until the profile is installed.

Quick answer for Huawei Mate 40 Pro

Yes, Huawei Mate 40 Pro may support eSIM. Huawei describes adding it through Settings > Mobile network > SIM management and lists single-SIM and dual-SIM 8 GB + 256 GB versions among the applicable products. One Huawei support page lists EMUI 11.0 and EMUI 12.0 for the feature; other regional pages can show different software versions. That variation is why the phone's own settings and market version matter.

Use this decision rule:

• If Settings > About phone > Show EID displays an EID, the phone has an embedded-SIM identity and is a candidate for activation.
• If Settings > Mobile network > SIM management shows an option to add or manage eSIM, the relevant interface is available.
• If neither appears, do not assume a QR code will work. The unit may have different regional firmware, an operator restriction or no eSIM component.

An EID is not an IMEI, phone number or physical SIM serial number. Huawei's guidance treats the EID as the decisive hardware check: if it is not displayed, the feature is not supported on that device according to those instructions. An EID is necessary evidence, not a guarantee that every provider or travel tariff will accept the phone.

Huawei Mate 40 Pro eSIM specifications at a glance

This is a compatibility framework, not a guarantee for every retail unit. Storage, memory, SIM tray design, firmware build and sales region can change the available menus. Do not merge Huawei Mate 40 Pro with Mate 40, Mate 40 Pro+, Porsche Design editions or another Mate series phone: similar names do not prove identical eSIM hardware.

Why regional and operator versions matter

The Mate 40 Pro was sold in different markets and SIM arrangements. Huawei lists both single-SIM and dual-SIM 8 GB + 256 GB versions in its eSIM guidance, while also warning that the feature varies by device, operator, country and region. This matters for imported, used and refurbished phones. Two units with the same commercial name can expose different menus or have different network restrictions.

Huawei describes the eSIM as using the logical SIM 2 position on some versions. On a dual-SIM phone, adding it may require the physical SIM in SIM 2 to be disabled. That can be normal for the configuration rather than evidence of a failed profile. Check the exact prompt on the phone.

Operator eligibility is separate from hardware support. A phone may have an EID but reject a profile because the device is network-locked, the provider does not support that model, or the service is unavailable in the market where the phone was sold. A travel eSIM also has destination and activation conditions. Confirm that the handset is unlocked and that the tariff covers the country, region or route before ordering.

Firmware can change menu wording. Huawei's regional support pages do not all list identical EMUI versions, and an imported phone may not show the same labels as a local one. Install available official updates, but do not factory-reset the phone just to search for eSIM support. A reset can delete stored profiles if the option to remove eSIMs is selected.

What eSIM changes in a travel setup

An eSIM is a digital SIM profile stored in the phone, not a second physical card. It can be useful when you want mobile data soon after landing, need to keep your usual number in the phone, or prefer to prepare the connection before visiting a local shop. The benefit depends on compatibility, the selected tariff and the networks available at the destination.

For a simple trip, the eSIM is usually the data line and the regular SIM is kept for the services you intentionally need. This does not automatically prevent roaming on the home line, so check the default-data and roaming switches before take-off. An eSIM also does not remove the need to check data allowance, validity, activation timing or hotspot rules. Those are conditions of the selected plan, not properties guaranteed by the phone.

If you are buying a used Mate 40 Pro, ask for a settings screen showing the EID and SIM management menu rather than relying on a box label. For an imported phone, confirm the sales region and whether its operator lock has been removed. This small check is easier before payment than after a QR code has been issued.

Check eSIM compatibility before you buy

Before selecting a travel tariff, treat this as the final pre-purchase check rather than a generic model claim. It takes only a few minutes and can prevent an unusable activation code. When the phone is in front of you, Check your device with this sequence. It is more reliable than a seller's claim that every Mate 40 Pro is identical.

1. Find the EID

Open Settings, choose About phone, and look for Show EID or an EID entry. The EID is normally a long numeric identifier. Confirm that the field exists; do not publish it or send it through an untrusted chat.

If there is no EID, do not substitute the IMEI. Recheck the exact device and install available official updates. If the field remains absent, treat the phone as incompatible until Huawei or the network provider confirms the regional unit.

2. Look for the eSIM control

Go to Settings > Mobile network > SIM management. Look for an add button, an eSIM entry or a control near SIM 2. Huawei describes adding, enabling, disabling, naming and deleting an eSIM in this area. Labels can vary by EMUI build, so look for the function rather than one exact translation.

If an eSIM is already listed, check whether it is enabled and whether the phone asks you to disable a physical SIM 2. Do not delete an old profile merely to test another one: Huawei warns that deletion may be irreversible and does not necessarily cancel the related service.

3. Confirm the phone is unlocked

An EID proves that the phone has eSIM capability, not that it accepts every network. A carrier-supplied phone can still have a network lock. A used phone can also have an account or activation restriction unrelated to its eSIM hardware. Resolve those issues before travelling.

4. Confirm the travel conditions

Check the selected eSIM tariff for destination, validity, data allowance, activation timing and supported network access. A country-specific profile may not cover a neighbouring country. For a multi-country route, use a regional option only when its listed coverage matches every stop.

Compatibility checklist

• [ ] The phone is exactly Huawei Mate 40 Pro.
• [ ] Show EID is present under About phone.
• [ ] SIM management contains an eSIM add or management option.
• [ ] The phone is unlocked, or the lock has been formally removed.
• [ ] The current EMUI build and sales region are known.
• [ ] The tariff covers the country, region or route.
• [ ] Reliable Wi-Fi or mobile internet is available for installation.
• [ ] You know whether logical SIM 2 requires the physical SIM 2 to be disabled.

When these checks pass, Kaspersky eSIM Store can help you choose and arrange an eSIM with a suitable mobile-data tariff for an overseas trip. The app and website let you review the destination and plan conditions, complete the eSIM order and activate the profile; they are not a mobile operator or the owner of the network used by the phone.

How to install an eSIM on Huawei Mate 40 Pro

Install the profile on a stable internet connection. Keep the QR code on another screen, securely printed, or available as an image if the activation flow supports it. Do not share the code publicly.

Step 1: prepare the phone

Charge the Huawei Mate 40 Pro, connect it to Wi-Fi and confirm the EID and eSIM menu. If two physical SIMs are inserted, note which one is in SIM 2 because the phone may ask you to disable it.

Step 2: open SIM management

Go to Settings > Mobile network > SIM management and select the add control next to SIM 2 or the eSIM entry. Depending on the EMUI build, the option can be labelled Add eSIM or Add mobile plan. If there is no add control, stop and recheck the EID, region, firmware and network lock instead of repeatedly scanning the code.

Step 3: add the profile

Choose the QR-code option and scan the activation code supplied after the eSIM order. If offered, use Select from Gallery for a saved QR image. If manual activation is available, enter the supplied code exactly. The phone may download the profile, request confirmation and restart; installation can take several minutes.

Huawei describes the eSIM as being added to logical SIM 2. On a dual-SIM version, follow the prompt if it asks you to disable physical SIM 2. Adding the profile and selecting it for mobile data are separate actions.

Step 4: enable the line

Give the profile a clear name such as Travel data. In SIM management, enable the eSIM and set it as the line for Mobile data when you are ready to use the travel plan. Keep your home SIM active only if its roaming conditions are acceptable.

Step 5: set data roaming as required

Many travel eSIMs require Data roaming for the eSIM because the profile connects through a partner network outside its home country. Turn roaming on for the travel eSIM only when the tariff instructions require it. Keep it off for the home line if you want to avoid accidental roaming charges.

Step 6: test the connection

After landing, select the travel eSIM for mobile data, turn off automatic data switching if offered, and wait a few minutes for registration. Open a simple webpage or messaging app. If the plan starts on first connection, its validity may begin at this point; follow the conditions supplied with the tariff. For more help, see the Android eSIM installation instructions and the iOS eSIM installation instructions. The Android guide is relevant to Huawei Mate 40 Pro; the iOS guide is for Apple devices.

Using eSIM for mobile data while travelling

Decide which line handles which task before leaving home. Use the travel eSIM for mobile data, keep the home SIM available only when you understand its roaming charges, and use Wi-Fi for large downloads or updates. This lets navigation, translation, transport apps, email and messaging work without buying a physical SIM after arrival.

For a multi-country itinerary, check the route before installation. A country profile may stop working at a border even though the eSIM remains enabled. A regional plan may suit the route, but only when all listed countries match your stops. Do not delete an active profile while travelling unless the provider tells you to; some profiles cannot be restored.

In this travel scenario, the eSIM is normally for mobile data. It does not automatically provide a local phone number, conventional voice calls or SMS. Those features exist only when the selected plan explicitly includes them. Messaging and voice apps can work over mobile data, but they do not create a regular local number.

Kaspersky eSIM Store helps you select, arrange and activate the eSIM tariff; the actual connection depends on the networks associated with the selected service and local availability.

Troubleshooting Huawei Mate 40 Pro eSIM

The EID is missing

Restart the phone, check About phone again, confirm the exact device and install available official updates. If the EID remains absent, treat the unit as unsupported. Contact Huawei or the provider with the model, software and sales-region details; never enter an IMEI in an EID field.

There is an EID but no Add eSIM option

Check the EMUI build, regional firmware and operator lock. Confirm whether a physical SIM is occupying SIM 2 on that variant. Huawei states that eSIM can vary by device, country, region and operator, so an EID does not eliminate these checks. Ask the provider about this exact unit before purchasing.

The QR code will not scan

Increase the brightness of the screen showing the code, display it in full and clean the camera lens. Use the gallery or manual option if supplied. Make sure it is the activation QR code, not a payment receipt. Do not repeatedly use a one-time code if the provider says it can be scanned only once.

The profile downloads but will not activate

Keep Wi-Fi connected, set date and time to automatic, and confirm that the tariff is intended for the current country or region. Make sure the profile is enabled. If activation begins only after arrival, wait for a supported destination network. A network lock, incorrect code or already-used profile may require provider assistance.

The eSIM is installed but there is no data

Set the travel eSIM as the mobile-data line, turn off automatic data switching, and enable data roaming for that line if required. Confirm that mobile data is on and airplane mode is off. Restart after changing settings. If the signal remains empty, move to a place with better reception and check the tariff's local network access.

The home SIM has unexpected roaming activity

Review the default data line and disable data roaming on the home SIM. Turn off automatic switching if the phone can change data lines when the preferred signal is weak. Ask your home operator about charges if the usage record is unclear.

You want to delete or reset the eSIM

Disable the profile before deleting it. Huawei warns that a deleted eSIM may not be restorable and that removing it from the phone does not necessarily terminate the related service. Before a factory reset, keep eSIMs only if you intend to preserve them. A reset that deletes eSIM information may require a new activation process.

FAQ

Does Huawei Mate 40 Pro support eSIM?

It can. Huawei lists single-SIM and dual-SIM 8 GB + 256 GB configurations as applicable eSIM products, but says the feature varies by device, operator, country and region. Confirm the EID and eSIM menu on your own phone.

Can I use a physical SIM and an eSIM together?

Often, but the arrangement depends on the variant. Huawei describes the eSIM as using logical SIM 2, and a dual-SIM phone may need physical SIM 2 disabled. Follow the on-screen prompt.

Do I need an EID to install a travel eSIM?

Yes, an EID is the clearest sign that the phone contains the embedded-SIM component. If no EID is shown, a QR code cannot add eSIM capability. The provider may also require an unlocked phone and a supported destination.

Will installing the eSIM cancel my regular SIM?

No. It adds a profile and does not automatically cancel a physical SIM or contract. You choose which line handles mobile data and should review both lines' roaming settings.

Can the eSIM make ordinary calls and send SMS?

Not unless the selected plan explicitly includes those services. Travel eSIMs in this context are intended for mobile internet. Messaging and voice apps can work over data without creating a local phone number.

Can I move the profile to another phone?

Do not assume that you can. Activation codes may be limited or linked to the first installation. Check the plan conditions before deleting or transferring a profile, and contact support if the phone is replaced.

Final device check and travel eSIM choice

Before travelling, verify that the device is exactly Huawei Mate 40 Pro, find Settings > About phone > Show EID, and confirm the Add eSIM control under Settings > Mobile network > SIM management. Check that the handset is unlocked, the EMUI and regional version are known, and you understand the logical SIM 2 arrangement. Match the tariff to every country or region on your route, its data allowance, validity period and activation conditions.

When those checks are complete, Kaspersky eSIM Store can help you choose, arrange and activate an eSIM with a suitable tariff for mobile data during an overseas trip. Install it on Wi-Fi, select it for mobile data when ready, and keep the activation details secure. This final check reduces the risk of paying for a profile that the specific regional or operator version of your Huawei Mate 40 Pro cannot add.
