Vivo V40 128GB eSIM: compatibility and setup guide

Quick answer: eSIM support is not confirmed for the Vivo V40 128GB variant as named here. vivo’s India specifications list an 8 GB + 128 GB V40 with two nano-SIM slots, but do not list eSIM. vivo’s specifications for some other V40 regional or operator versions do list eSIM support. That difference means the family name and storage capacity alone cannot establish whether your individual phone can install an eSIM. Before choosing a travel data plan, check the phone itself for an EID and an eSIM setup option, then confirm the model code and market with the seller or vivo support.

Does the Vivo V40 128GB support eSIM?

There is not enough public official evidence to say that every Vivo V40 128GB supports eSIM. The most specific official listing found for a 128 GB configuration is vivo India’s V40 page, which identifies 8 GB + 128 GB storage and describes a tray for two nano-SIMs. That page does not list eSIM in its connectivity specifications. For a phone matching that Indian-market specification, treat eSIM compatibility as unconfirmed and do not assume it will work unless the handset’s own settings and EID check confirm otherwise.

The V40 name is used for regional configurations with different network and SIM details. vivo’s European V40 5G specifications state that eSIM is supported alongside two nano-SIM slots. vivo’s Mexico specifications are more specific: they describe an eSIM-compatible version and identify a single-SIM configuration for Claro Mexico and Colombia, while other configurations use two nano-SIMs. The listed regional pages do not establish that the 128 GB handset sold in India—or a phone imported from another market—has the same eSIM hardware and software. A model with a similar name, color, processor, or appearance is not proof of identical SIM capability.

The practical answer is therefore conditional: some Vivo V40 regional or operator versions support eSIM, but eSIM is not verified for the Vivo V40 128GB variant from the name alone. The exact model code, original sales market, installed firmware, and carrier configuration matter. Storage size by itself is not an eSIM feature, and changing Android settings or updating apps cannot add eSIM hardware to a phone that lacks it.

Regional sales variants and operator-specific configurations can differ. An imported or second-hand phone may not match the version sold in your current country. Your travel destination affects plan and network choice, but not the handset’s built-in eSIM capability.

Use official regional specifications as a reference, then verify the phone in your hand. If the seller cannot confirm its model code and eSIM capability, ask vivo support. A general statement that “V40 supports eSIM” does not settle your unit’s configuration.

Check compatibility before buying a travel plan

Check the Vivo V40 128GB itself: a retailer title or generic compatibility list is not enough. Menu wording varies by region and software version.

Compatibility checklist

• Find the model code. Open Settings → About phone and note the model number, software version, and country or region information shown there. Compare the code with the invoice, box label, or seller’s listing. Share the code—not private account details—with vivo support if you need a definitive answer.
• Look for an EID. In the Phone app, enter *#06# and check whether the device displays an EID in addition to its IMEI numbers. You can also look in Settings → About phone → Status or a similar status page. An EID is an identifier associated with eSIM hardware. If no EID is shown, that is a strong reason to stop and verify with vivo; menu behavior can differ, so do not use this check alone to declare the phone incompatible.
• Look for eSIM controls. Open Settings → Mobile network (sometimes called SIM card & mobile network) and look for eSIM, Manage eSIM, Add eSIM, or Download a SIM. If you see a QR-code installation option, check whether it opens rather than relying only on the label.
• Check for an operator lock. Ask the original carrier or seller whether the phone is unlocked and permitted to use a travel eSIM. A compatible eSIM radio does not remove a network lock.
• Confirm plan requirements. Check the destination, data allowance, validity period, supported network, activation timing, and whether the plan requires data roaming. A data-only travel eSIM does not ordinarily replace your home number for cellular voice calls or SMS; use messaging and calling apps over data if appropriate.
• Keep internet available during setup. Downloading an eSIM profile generally requires a working Wi-Fi or mobile connection. Install before travel while you have reliable internet, unless the plan’s instructions specify another timing.

A retail listing that gives storage but omits the regional model code cannot settle eSIM support. Ask the seller which model number and market the handset belongs to, then compare it with vivo’s regional information. If the model code is unclear, confirm it before checkout. Check your device compatibility before choosing a travel plan. If the phone has no EID or eSIM option, confirm the model code with vivo or the seller before purchase.

What to do if the Vivo V40 128GB passes the checks

If the handset shows an EID and an eSIM installation control, verify the version with vivo or the seller and then follow the plan’s device-specific instructions. Before paying, confirm that the eSIM plan covers your destination and intended dates. A phone can support eSIM in general while a particular provider’s profile or a particular local network is not suitable for that phone or journey.

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 international trip. It is not the mobile operator or the network itself. The plan’s conditions identify the included data, destination, validity, and activation rules. Check those details, the device compatibility, and the phone’s carrier-lock status before you proceed.

How to install and activate an eSIM

Menu names can vary by market and software version, so follow the plan’s instructions if they differ. Do not delete a profile as a shortcut: its QR or activation code may be single-use.

1. Confirm compatibility and unlock status. Check that the Vivo V40 128GB has an EID and a working eSIM option, and confirm that the phone is not restricted by its original carrier.
2. Prepare a stable connection. Connect to Wi-Fi or another reliable internet connection. Keep the phone charged and have the activation QR code or installation details ready on a different screen or printed page.
3. Open SIM settings. Go to Settings → Mobile network or Settings → SIM card & mobile network, then choose eSIM or Add eSIM. If there is no such option, stop and verify the device version instead of repeatedly scanning the code.
4. Add the profile. Choose the QR-code option and scan the code provided in your account or confirmation message. If the plan supplies manual activation details, enter them only in the phone’s eSIM setup screen and follow the plan instructions.
5. Wait for installation. Keep the phone online while it downloads the profile. The installation prompt may ask you to name the line; use a clear label such as “Travel data” so you can distinguish it from your home SIM.
6. Choose when to enable it. If you install before departure, you can leave the travel line off until the plan’s instructions say to turn it on. Activation and the start of data use are not always the same event; check the plan terms so the validity period begins when expected.
7. Set the data line. In SIM or mobile network settings, select the travel eSIM for mobile data. Keep your regular SIM selected for calls or texts if you need it, and check its roaming setting to avoid unwanted charges from your home carrier.
8. Enable data roaming only if required. Some travel eSIMs need roaming enabled on that eSIM to connect to a partner network. Turn it on for the travel profile only when its instructions require it; it does not mean you should enable roaming on your home SIM.
9. Check the connection. At the destination, enable the travel eSIM, confirm mobile data is assigned to it, and wait for network registration. If the plan specifies a network-selection step, choose an available supported network as instructed.

For illustrated setup steps, see the Android eSIM installation instructions; the walkthrough is Samsung-specific, so Vivo menu labels may differ. The iOS guide is useful when helping another traveller or comparing general setup concepts: iPhone eSIM installation instructions. The Vivo V40 128GB runs Android; use the Android path for this phone.

Using a travel eSIM for mobile data

When the eSIM is active and registered on a supported local network, choose it as the mobile-data line. You can usually leave your home SIM enabled for incoming calls or messages, but the exact dual-SIM behavior depends on the handset and carrier. Check call forwarding, voicemail, and roaming conditions with your home provider if those services matter. The travel data plan itself may not include a conventional phone number, voice calls, or SMS unless its terms expressly say so.

Plan for a few common situations:

• Before departure: Install over Wi-Fi if the plan permits, label the profile, and confirm when to turn it on and when validity begins. Save setup steps offline.
• After landing: Enable the travel line, assign it to mobile data, and follow network or roaming instructions. Allow time for registration.
• On a multi-country route: Check that every destination is included; a country plan may not cover the next stop.
• To conserve data: Check remaining allowance in the provider’s app or account and limit background downloads. Confirm hotspot use is allowed before relying on it.

Kaspersky eSIM Store helps travellers select and activate eSIM plans for mobile internet abroad through its app and website. To browse available destinations and check current plan details, visit the Kaspersky eSIM Store. The available destination and plan conditions can change, so review the current details for your actual route before checkout.

Common problems and checks

There is no Add eSIM option. Check the model code and software version, then look again under Mobile network or SIM card settings. If the V40 128GB is the Indian-market two-nano-SIM version described on vivo’s page, eSIM is not documented for that configuration. An operating system update may change menu wording, but it cannot turn unsupported hardware into eSIM hardware. Ask vivo support to confirm the exact unit.

The phone shows no EID. Restart once and check both the dialer’s *#06# screen and the About phone or Status section. If the EID is still absent, do not assume compatibility based only on the V40 name. Confirm with vivo or the seller before purchasing a plan.

The QR code will not scan. Increase screen brightness, clean the camera lens, and hold the code steady with the entire code in view. If possible, display it on another device. Check that the code has not already been used and that it belongs to the intended plan. Do not post the QR code publicly; it can contain private activation credentials.

The profile download fails. Check internet access, disable any setting that interrupts the connection, and try again on a stable Wi-Fi network. Confirm that the date and time are automatic and that the phone has enough free storage. If the setup screen says the code was already used or is invalid, contact the plan’s support team before removing an existing profile or requesting a replacement.

The eSIM installs but shows no service. Confirm that the plan is valid for the country you are in and that its activation conditions have been met. Turn the travel line on, select it for mobile data, and check whether its instructions require data roaming or manual network selection. Toggle airplane mode off and on, wait briefly, then restart the phone if needed. Network availability also depends on local coverage and device network compatibility.

Data does not seem to work. Check that mobile data is assigned to the travel eSIM rather than the home SIM, that the plan still has data and validity, and that the correct line is enabled. If the provider gives APN instructions, enter only the values supplied for that plan. Turn off Wi-Fi briefly to test mobile data, then restore Wi-Fi if needed.

The eSIM is blocked or the phone is locked. A carrier lock can prevent activation even when the phone includes eSIM hardware. Contact the original carrier or seller about unlocking; a travel-plan provider cannot change the device’s lock status. If the plan is active but setup remains blocked, contact the plan support team with the error message, device model code, and time of the attempt. Never send a full QR code or password in a public post.

If you need your main number, test the dual-SIM setup before travel; available combinations can vary. Note your original SIM settings so you can restore them.

Frequently asked questions

Is Vivo V40 128GB definitely eSIM-compatible?

No definitive yes can be given from the name and storage size alone. vivo India lists an 8 GB + 128 GB V40 with two nano-SIM slots and does not list eSIM on that specification page. Other V40 regional or operator versions are documented with eSIM. Verify your phone’s EID, settings, and model code.

Does every Vivo V40 support eSIM?

No. vivo’s published regional specifications show differences: eSIM appears for some versions, while the India listing for the 128 GB configuration lists two physical SIMs without documenting eSIM. Confirm the country and exact model code rather than generalizing from another V40.

Is the 128 GB storage size what determines eSIM support?

No. Storage capacity does not itself enable or disable eSIM. The relevant factors are the device’s hardware, regional configuration, software, and sometimes operator customization. The 128 GB listing is useful as a clue to the sales market, not proof of eSIM support.

Can a software update add eSIM to my phone?

A software update can change settings or fix software issues on a phone that already has compatible hardware. It cannot add an eSIM component to a model that does not have one. Confirm with vivo if your EID or eSIM controls are missing.

Can I install a travel eSIM before my trip?

Usually you can install a profile in advance if you have internet and the plan’s activation instructions permit it. Check when the plan validity starts, and follow its timing guidance so you do not use the plan earlier than intended.

Will the travel eSIM replace my regular SIM?

It does not have to. If the handset supports the intended dual-SIM setup, you may keep the home SIM enabled and select the eSIM for data. Check roaming charges and remember that a data-only plan may not provide a phone number, ordinary calls, or SMS.

What if my V40 has no EID or eSIM menu?

Do not buy a plan on the assumption that it will work. Confirm the model code and original market with vivo or the seller. If the exact phone does not support eSIM, use a supported physical SIM option or another unlocked device that has confirmed eSIM capability.

Before you travel: check the phone, then choose the plan

For the Vivo V40 128GB, check the model code, EID, and Add eSIM setting. vivo India lists two nano-SIMs for its 8 GB + 128 GB version without confirming eSIM; some other regional or operator configurations do list it. Verify your own handset before purchase.

When compatibility and unlock status are clear, choose a plan for your route and check its data, validity, activation timing, and network instructions. Kaspersky eSIM Store is an app and website that helps you choose, arrange, and activate an eSIM plan for mobile data on an international trip. If your V40 cannot add an eSIM, choose a compatible device or physical-SIM option.
