Why eKYC is indispensable for your eSIM
eKYC (Electronic Know Your Customer) verification is an essential process for securing and activating certain digital services, including eSIMs. When traveling abroad, it is sometimes mandatory to confirm your identity to comply with the legal requirements of the countries concerned. We’ll tell you about eKYC, its importance for eSIM users, and how to perform it easily!

What is an eSIM?

Before understanding the importance of eKYC, let’s remember what an eSIM is. An eSIM, or embedded SIM, is a SIM card integrated directly into a compatible device. Unlike traditional physical SIM cards, an eSIM is entirely digital and offers several advantages for travelers:
- Connect to a mobile network immediately after landing, without looking for a local store.
- Avoid queues to get a physical SIM card.
- Easily change plans or networks via a mobile application.
- Reduce roaming charges thanks to plans tailored to each country visited.
Thanks to their flexibility, eSIMs are particularly popular with international travelers, but their activation may be subject to specific requirements, such as eKYC verification.

What is eKYC verification?

eKYC, or electronic Know Your Customer verification, is a digital procedure for verifying a user’s identity.

Unlike traditional paper-based verification, eKYC relies on digital documents, such as a photo of your passport, and offers a fast, efficient, and eco-friendly method to authenticate users.

Here are the main advantages of eKYC:
- Speed: Verification often takes only a few minutes.
- Simplicity: No need to print or submit physical documents.
- Security: Reduces the risk of fraud and protects your personal data.
- Environmental friendliness: Eliminates the need for paper.
In summary, eKYC facilitates access to digital services while ensuring strict compliance with international regulations.

Why do some eSIMs require eKYC verification?

Many countries impose KYC protocols to ensure that each user is properly identified. This measure aims to prevent abuses such as fraud or illegal activities, while protecting national security.

For eSIMs, eKYC is particularly important for:
- Complying with local laws: Some countries require formal identification to access telecom services.
- Ensuring communication security: By verifying each user’s identity, the risk of fraudulent network use is reduced.
- Simplifying border control: eKYC can be linked to customs or administrative checks in some cases.
If you purchase an eSIM in a country with strict restrictions, eKYC verification may be required before your plan is activated.

How to perform an eKYC verification?

eKYC verification is a simple process that can generally be completed in a few minutes via your eSIM provider’s application. Here are the typical steps:
1. Prepare your documents: Take a clear photo of your passport or official ID.
2. Open the application: Log in to your eSIM provider’s app, such as Vostra, and start the verification process.
3. Upload your document: Upload a digital copy of your ID via the app’s interface.
4. Await validation: Verification is usually automated and takes only a few minutes. You will receive a confirmation once the process is complete.
To avoid any delays, it is advisable to complete this procedure before your departure, especially if you are traveling to a country with legal restrictions on mobile communications.

FAQ

Which countries require eKYC verification for eSIMs?

Countries with strict telecommunication regulations, such as India, some Middle Eastern states, or Southeast Asian countries, may require eKYC verification. Check your destination’s specific requirements before purchasing an eSIM.

How long does eKYC verification take?

Verification is often completed in a few minutes, but this depends on the quality of the documents provided and the platform used.

What documents are needed to perform eKYC verification?

A passport or official photo ID is usually required. Make sure your document is clear and legible before uploading it.

Is eKYC verification mandatory for all eSIMs?

No, only certain eSIMs, particularly those used in countries with strict regulations, require eKYC verification. Check your plan’s terms before purchase.

eSIM vs. SIM card: What are the differences?
The world of mobile telephony is constantly evolving, and with it, the technologies that keep us connected. For decades, the physical SIM card has been the standard for accessing mobile networks. But a major innovation is revolutionizing this approach: eSIM.

This virtual SIM card, integrated directly into the device, simplifies access to mobile networks without requiring a physical medium. But what exactly is an eSIM? How does it work? And above all, how is it different from a traditional SIM card? All the answers are in this article!
What is an eSIM and how does it work?

The term « eSIM » stands for « Embedded SIM », meaning a SIM card integrated directly into a mobile device. It is a chip soldered to the motherboard of the phone or any other compatible device.

It functions in the same way as a physical SIM card by authenticating the user to a mobile network. However, it does not require a physical medium and can be activated or reprogrammed remotely, without needing a card change. When a user wishes to activate a mobile plan with an eSIM, they must follow a few simple steps:
1. Order an eSIM plan from a mobile operator or a provider like Vostra.
2. Receive a QR code or an activation code.
3. Scan the QR code via your device’s settings.
4. Configure the eSIM as a primary or secondary line.
5. Activate the connection to mobile networks.
Once the eSIM is activated, the user can change plans or networks without having to remove a card.

In addition to smartphones (iPhone, Google Pixel, Samsung Galaxy, etc.) and tablets (iPad Pro, iPad Air, etc.), eSIMs can be configured on smartwatches (Apple Watch, Samsung Galaxy Watch, etc.) and some laptops (Microsoft Surface, Lenovo ThinkPad, etc.).

The evolution of SIM cards

The SIM card has undergone numerous transformations since its appearance in the 1990s:
- Initially introduced in the 90s, the classic SIM card was the size of a credit card.
- Over the years, it was gradually reduced to mini SIM, then micro SIM, and finally nano SIM, the most common format today.
- In 2017, the arrival of eSIMs marked a major advance by permanently integrating the chip inside the device. Presented at the Mobile World Congress (MWC), the eSIM became the very first fully digital chip, offering unprecedented capabilities in terms of flexibility and security.
With eSIM, the mobile industry is moving towards a dematerialized approach, where changing operators and plans can be done in a few clicks.

Differences between an eSIM and a physical SIM card

Although both types of chips (physical and digital) fulfill the same fundamental objective, eSIMs offer several significant advantages:

📌 Characteristics of physical SIM cards
- Require manual insertion and removal.
- Can be lost or damaged.
- Do not allow instant network switching.
- Requires physical availability (purchase and delivery).
📌 Characteristics of eSIMs
- Integrated directly into the device.
- Activatable and reprogrammable remotely.
- Impossible to lose or steal.
- Ideal for travelers thanks to quick switching between operators.
- Compatible with multiple plans simultaneously.
How to activate an eSIM?

Generally, after purchasing your eSIM plan from a provider like Vostra, you immediately receive an email containing detailed instructions for activation. Here are the key steps:
1. Purchase your eSIM from an online provider (like Vostra).
2. Receive an email or consult the app with instructions on how to install your eSIM profile.
3. Follow the steps indicated on your smartphone (usually by scanning a QR code or manually entering a provided code).
4. Your eSIM activates in a few moments, connecting you to the desired mobile network.
Thanks to this ease of use, you can easily switch from one operator to another, activate a local plan when traveling, or manage multiple plans simultaneously without hardware constraints.

FAQ

Why is eSIM more secure than a physical SIM card?

The eSIM is integrated directly into the device and cannot be removed or swapped like a classic SIM card. This reduces the risks of theft or fraud through SIM swapping, a technique often used to hack bank accounts or online services.

Can an eSIM be transferred from one phone to another?

Yes, but unlike a physical SIM card that can be moved from one phone to another in a few seconds, transferring an eSIM depends on the operator. Some allow easy transfer via their app, while others require a new activation with a QR code.

Does eSIM work in all countries?

eSIM works in most countries, but this depends on operators and roaming agreements. Some eSIMs are designed for local use, while others offer global plans. At Vostra, we offer eSIM plans tailored for international travel.

Do all mobile operators accept eSIM?

More and more operators support eSIM, but it is not yet universal. Before switching to eSIM, it is advisable to check if your current operator or your destination’s operator supports this technology.
What are the disadvantages of eSIM compared to a physical SIM card?
While eSIM offers many advantages, it does have some limitations:

Transferring between devices can be less straightforward than with a traditional SIM card.

Some operators do not yet offer eSIM support.

If your phone is damaged, you cannot simply remove the SIM to use it in another device.
How many eSIM profiles can be stored on a smartphone?

This depends on the phone model. Most compatible smartphones allow you to save several eSIM profiles, but only one can be active at a time. On some devices, like recent iPhones, it is possible to activate two eSIMs simultaneously.

Dual SIM: how to use eSIM and SIM card at the same time?
The eSIM is a game-changer for connected travelers. No more juggling traditional SIM cards upon arrival at your destination: everything is done remotely, directly from your smartphone. Discover the real differences between physical SIM cards and eSIMs, and how to use both technologies simultaneously when traveling abroad.
Differences between physical SIM card and eSIM

Unlike traditional SIM cards, eSIMs are digital SIM cards directly integrated into the device. This allows for faster and more secure setup.

You can install an eSIM without going through a point of sale or waiting for postal delivery. Since the eSIM is embedded in the phone, it cannot be removed or stolen.

No physical manipulation means fewer technical problems related to wear and tear or poor contacts. eSIMs are more eco-friendly, and therefore more sustainable, as they avoid plastic production and unnecessary shipping.

Using a SIM card and an eSIM simultaneously: how-to guide

If your smartphone is Dual SIM compatible, you can use both a physical SIM card and an eSIM. This can be practical for separating professional and personal use, or for activating a local line during a trip while keeping your main line active.

1. Label your plans

To avoid confusion, assign a name to each line (e.g., “SIM France” and “eSIM Thailand”).

On iOS:
- Open Settings > Cellular.
- Tap on your eSIM, enter a custom name, then save.
On Android:
- Go to Settings > Network & internet > SIM cards.
- Select your eSIM and name it.
2. Activate your eSIM

On iOS:
- Open Settings > Cellular.
- Select your eSIM.
- Activate Turn On This Line and Data Roaming.

- Android: Settings > Network > SIM card > Calls/SMS.
Mobile data:

Choose the line to use for internet access.
- iOS: Settings > Mobile data > select eSIM.
- Android: Settings > Mobile network > select eSIM.
Switching from an eSIM to a physical SIM card (or vice versa)

You can temporarily deactivate your eSIM at any time, for example after a trip, and reactivate your usual SIM card for calls and data. This avoids having to reinstall an eSIM profile later.

Deactivate an eSIM
- iOS: Settings > Mobile Data > eSIM > deactivate.
- Android: Settings > Connections > Mobile network > deactivate eSIM.
Is your phone compatible with eSIMs?

Most recent smartphones (since 2018) are compatible with eSIM technology. However, your device must also be unlocked (not tied to a specific carrier).

To check, consult the official list of compatible models or dial *#06# on your device to see if it displays an EID (eSIM identifier) number.

Dual SIM smartphones also allow you to combine an eSIM and a physical SIM in parallel. This is ideal for travelers who want a local line while keeping their main number active.

FAQ

Can I use my main SIM card for calls while using an eSIM for internet?

Yes, this is entirely possible if your phone supports dual SIM. You can configure your eSIM to handle mobile data (internet), while keeping your physical SIM card for calls and SMS. Simply set the default lines in your phone’s network settings.

How many eSIM profiles can I save on a single phone?

Most modern smartphones allow you to save between 5 and 8 eSIM profiles. However, only one can be active at a time. This allows you to keep multiple international plans and activate them depending on the country you are in.

What happens if I change phones? Will my eSIM still work?

The eSIM is linked to a single device. If you change phones, you will generally need to download a new eSIM profile via your carrier or a platform like Vostra. This is quick, but it requires a new activation.

How do I prioritize one line for calls, and another for internet?

In your phone’s settings, you can choose which line to use for mobile data, for voice calls, and for SMS. These options are found in the « Mobile network » or « Cellular data » section. You can change these settings at any time.

5 good reasons to choose a prepaid eSIM rather than roaming abroad
When you travel, Internet access is essential for using your apps, checking your emails, or finding your way. But connectivity options abroad can quickly become expensive, especially if you use traditional roaming. Fortunately, prepaid eSIMs offer a more economical and practical alternative. Here are 5 arguments that show why 👇.

1. You get what you pay for

With a prepaid eSIM, you have total transparency regarding your consumption and expenses. Unlike traditional roaming plans, which can include hidden fees and unexpected costs, each eSIM plan clearly specifies:
- The amount of data included (3 GB, 5 GB, etc.).
- The validity period (one week, one month, etc.).
- The total cost with no hidden fees.
- The networks and countries covered.
- Whether the eSIM includes calls/SMS or data only.
- Activation and renewal conditions.
In contrast, with a traditional roaming plan, several aspects are beyond your control:
- The total cost of roaming, often difficult to anticipate.
- Possible surcharges when switching from one network to another.
- Coverage quality, which can vary depending on the operator.
In summary, a prepaid eSIM gives you the ability to perfectly control your budget while enjoying a reliable connection.

2. You won’t exceed your data plan

Prepaid eSIM plans operate on a simple principle: you purchase a defined amount of data and use it as needed. This means:
- The cost remains fixed: you only pay for the data chosen.
- Your plan lasts until its expiration or until all data is used.
- Once the plan is exhausted, you have the choice to renew it or not.
With traditional roaming, it’s common to exceed your data plan without realizing it, leading to exorbitant costs. A prepaid eSIM eliminates this risk and allows you to better manage your consumption.

3. You can easily change your plan

When you use an eSIM, changing plans is as simple as downloading a new data plan. For example, if you’re traveling in Asia and move from Thailand to Malaysia, you can switch from one local plan to another without changing your physical SIM card.

If your phone is compatible with the Dual-SIM function (one physical SIM + one eSIM), you can even keep your primary number and use an eSIM for data.

4. eSIMs are fully digital

One of the great advantages of eSIMs is that they are completely digital. You can purchase and activate a plan in minutes, without having to search for a point of sale or wait for delivery.

Benefits of a digital eSIM include:
- No more waiting to get a physical SIM card.
- No need to search for a local SIM card provider.
- Eliminates the risk of losing or damaging your SIM card.
All you need is a compatible phone and a Wi-Fi connection to activate your plan.

5. Prepaid eSIM plans are more affordable

Roaming fees can quickly become very expensive, especially if you travel frequently. A prepaid eSIM plan is often much more economical because it operates on a simple, no-commitment model.
- No hidden fees.
- Competitive prices compared to roaming plans.
- Better network coverage, as the eSIM can connect to the best local operators.
What if I need a phone number while traveling?

Many prepaid eSIM plans focus on data and do not include a local phone number. However, this doesn’t mean you can’t make calls!

Here are some alternatives:
- Use apps like WhatsApp, Telegram, Skype, or Zoom to make calls over the Internet.
- Send SMS via iMessage, WhatsApp, or other messaging apps.
- Receive confirmations and security codes by email rather than SMS.
If you need a local number, some eSIMs offer options that include calls and SMS, available on Vostra.world.

FAQ

Is my phone compatible with a prepaid eSIM?

To check, go to settings and look for the « Add eSIM » option, or dial *#06# to see if an EID number appears.

How do I activate a prepaid eSIM?

Purchase a plan on Vostra.world, scan the received QR code, and follow the instructions for activation.

Do prepaid eSIMs work in all countries?

Yes, Vostra.world offers plans for hundreds of countries and regions. Check our website to see available offers.

- Data: Volume of data included in the plan (e.g., 5 GB, 10 GB).
- Validity: Duration of the plan’s use (e.g., 7 days, 30 days).
- Network: List of partner operators offering coverage.
- Activation policy: Some plans activate upon installation, others only upon connection to the network.
eKYC: Electronic Identity Verification

Some countries require electronic identity verification (eKYC) before authorizing the activation of an eSIM plan. This involves providing identity documents to validate your account. If your destination imposes this requirement, remember to complete this verification before your departure.

Recharge option

Many eSIM plans allow you to recharge your data without having to reinstall the eSIM. If your plan does not offer this option, you will need to purchase a new one upon expiration.

Frequently Asked Questions

How does a Vostra eSIM work?

A Vostra eSIM allows you to connect to a mobile network without the need for a physical SIM card. Once activated, it gives you access to mobile services such as data, calls, and SMS (if included in the plan). The eSIM operates entirely digitally, unlike a traditional SIM card, which makes it easier to activate and use, especially for travelers.

When is the best time to install an eSIM?

The ideal time to install your eSIM depends on its activation policy. If your eSIM activates immediately after installation, it’s best to wait until you are ready to use it before installing it on your device. However, if it only activates upon connecting to the network at your destination, you can install it any time before your departure.
When and how to activate an eSIM?
eSIMs have different activation policies, depending on the operator and the type of plan chosen:

Immediate activation: Some eSIMs are activated as soon as they are installed on your device. They then start consuming their plan immediately.

Activation upon connection: Other eSIMs only activate when they detect a mobile network in the area covered by the plan.

Make sure to check your eSIM’s activation policy before installing it.
Can I use an eSIM with a locked phone?

No, your phone must be unlocked by your operator to use an eSIM. An unlocked phone means you are not tied to a single operator and have the freedom to change plans, use an eSIM, or a local SIM when you travel. If your device is locked, contact your operator to see if it can be unlocked.

Having multiple eSIMs on your phone: why it’s a good idea
With the rise of eSIMs, it’s now possible to have multiple digital SIM profiles on a single device. This technology, of course, revolutionizes mobile connectivity, especially for travelers and professionals. But what are the concrete advantages of having multiple eSIMs on one phone? We invite you to discover them!

What is an eSIM?

An eSIM, or embedded SIM, is a digital version of the traditional SIM card. Unlike physical cards, it is integrated directly into the device and can be activated remotely via a QR code or an application.

Among the advantages of an eSIM are:
- No longer needing to buy and manage physical SIM cards.
- Instant access to international mobile plans.
- Easy installation via Wi-Fi, without requiring physical intervention.
- The ability to store multiple eSIM profiles on a single device.
eSIMs vs. physical SIM cards: what are the differences?

Whereas with multiple eSIMs, everything is managed digitally, which greatly simplifies the user experience.

A global eSIM works in over 200 countries, perfect for frequent travelers.

Once the eSIM is installed, it activates automatically as soon as you connect to a compatible network. You can check its activation in your phone settings, under « Mobile Data » or « Cellular Plans. »

If you have lost your QR code, you can usually find it in your purchase confirmation email. With Vostra, you can also log back into your account and retrieve your eSIM.

No, an eSIM is generally tied to a single device once activated. If you change phones, you will need to get a new eSIM and follow the installation process on the new device.

This depends on your smartphone model. For example, recent iPhones allow you to store multiple eSIMs and switch between them, but can only activate two lines simultaneously (one eSIM and one physical SIM or two eSIMs).
