vivo V40 eSIM

Does the vivo V40 support eSIM?

vivo V40 eSIM compatibility

Yes, the vivo V40 supports eSIM. The device offers a Nano-SIM + eSIM configuration, giving you dual-SIM functionality without needing two physical SIM slots occupied. You can use one physical Nano-SIM card alongside one eSIM profile simultaneously.

This eSIM support applies to the vivo V40 models available in most markets. However, because eSIM availability can vary by region and carrier, confirm with your local carrier that they provision eSIM profiles before purchasing a plan. The vivo V40 does not support dual eSIM operation—you must use at least one physical SIM alongside your eSIM.

Dual SIM capability on the vivo V40

The vivo V40 handles dual standby, meaning both your physical SIM and eSIM remain active for calls and data. You can assign one line for data and another for voice, or switch between them depending on coverage and cost. This setup is particularly useful when traveling, letting you keep your home number active for calls and texts while using a local eSIM for affordable data.

How to set up an eSIM on the vivo V40

Set up an eSIM in Settings

Setting up an eSIM on your vivo V40 takes about sixty seconds. You'll need a QR code from your eSIM provider, a stable Wi-Fi connection, and access to your phone's settings. Here's how to activate your eSIM:

1. Open Settings on your vivo V40.
2. Tap Network & internet or SIM cards & mobile networks (the exact label depends on your software version).
3. Select Add mobile plan or eSIM.
4. Tap Scan QR code and point your camera at the QR code provided by your eSIM carrier.
5. Confirm the plan details and tap Add or Download.
6. Wait for the eSIM profile to download and activate—this usually completes within a minute.
7. Label your lines (for example, "Home" and "Travel") so you can easily identify which SIM to use for data, calls, or messages.

Installing your vivo V40 eSIM profile

If your eSIM provider sends an activation code instead of a QR code, choose Enter activation code manually in the SIM settings and type in the string provided. Once the profile installs, you'll see it listed under your SIM card settings, and you can toggle it on or off as needed.

Using a travel eSIM on the vivo V40

A travel eSIM is the simplest way to stay connected abroad without paying roaming fees on your home plan. Instead of hunting for a local SIM card at the airport, you install an eSIM profile before you fly and have data as soon as you land. The vivo V40 eSIM setup makes this process straightforward: purchase a data plan for your destination, scan the QR code, and you're ready.

You can browse eSIM plans for hundreds of countries and regions, often with flexible validity periods from a single day to a month or more. Because the eSIM is digital, you can install multiple profiles and switch between them in settings—useful if you visit several countries on one trip. Your physical SIM stays in place, so you'll still receive calls and texts on your home number while the eSIM handles data.

Install before departure

Install your travel eSIM while you're still at home on Wi-Fi. Most eSIM plans activate only when they detect the destination network, so downloading the profile early won't waste your data allowance. Once you arrive, enable data roaming for the eSIM line (more on that in the next section), and your vivo V40 will connect automatically.

Tips & troubleshooting

Turn on data roaming for the eSIM line

Even though you're using a local eSIM, the vivo V40 treats it as a secondary line, and data roaming must be enabled for that profile. Go to Settings > Network & internet > SIM cards, select your eSIM, and toggle Roaming on. Don't worry—you won't incur roaming charges because the eSIM itself is the local plan.

Set your eSIM as the default data line so apps and browsers use it instead of your home SIM. You can still choose your home SIM for outgoing calls and SMS, keeping your travel setup clean and cost-effective.

Fix an eSIM that won't activate

If the QR code won't scan, check that your camera lens is clean and the code is displayed at full brightness on another screen. Alternatively, use the manual activation code entry method. If the eSIM downloads but doesn't connect, restart your vivo V40—this often refreshes the network registration. Confirm that your carrier supports eSIM and that the plan is active in their system; some providers require you to activate the eSIM in their app or website first.

For persistent issues, delete the eSIM profile from your vivo V40 settings and reinstall it. Each QR code is typically single-use, so request a new one from your provider if needed. You can also check another device's eSIM compatibility if you're troubleshooting across multiple phones, or visit our eSIM setup help resource for step-by-step guidance.

Keep your home SIM for calls and two-factor authentication

Leave your physical SIM installed and active even when using a travel eSIM. Many banking apps, email services, and social platforms send verification codes via SMS to your home number. With both lines active on the vivo V40, you'll receive those messages without interruption while your eSIM handles data. Just make sure you've disabled data on your home SIM to avoid accidental roaming charges.
