Why eKYC is essential 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 recall 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 with plans adapted 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 for authenticating 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 may be linked to customs or administrative checks in some cases.
If you purchase an eSIM in a country with strict restrictions, an eKYC verification may be requested before your plan is activated.

How to perform an eKYC verification?

eKYC verification is a simple process that can usually be completed in 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 app: Log in to your eSIM provider’s app, like Vostra, and start the verification process.
3. Upload your document: Upload a digital copy of your ID via the app interface.
4. Wait for 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, certain 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 for eKYC verification?

A passport or official photo ID is generally 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 the conditions of your plan before purchasing.

7 good reasons to travel with a Vostra eSIM
With the evolution of mobile technologies, eSIMs (embedded SIM cards) are gradually replacing traditional physical SIM cards. This innovation simplifies access to mobile networks and offers increased flexibility, especially for travelers. But what are the differences between a classic SIM and an eSIM? What are the advantages of this technology, in particular? This article will help clarify things for you!

2. Maximum flexibility

With an eSIM, you have the freedom to easily switch between different mobile plans depending on your travels. If you travel to multiple countries, you can have several network profiles simultaneously and switch from one operator to another without physically changing your SIM card.

This flexibility allows you to choose the best offer at any time, based on prices, network coverage, and your specific needs.

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: the eSIM.

This virtual SIM card, integrated directly into the device, simplifies access to mobile networks without requiring physical support. But what exactly is an eSIM? How does it work? And most importantly, 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 » means « Embedded SIM« , which is 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 works in the same way as a physical SIM card by authenticating the user to a mobile network. However, it does not require physical support and can be activated or reprogrammed remotely, without needing a card change. When a user wants 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 certain 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 progressively reduced to become 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 then became the very first fully digital chip, offering unprecedented capabilities in terms of flexibility and security.
With the eSIM, the mobile industry is moving towards a dematerialized approach, where changing operators and plans is done in just a few clicks.

Differences between an eSIM and a physical SIM card

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

📌 Features of physical SIM cards
- Require manual insertion and removal.
- Can be lost or damaged.
- Do not allow instant network switching.
- Require physical availability (purchase and delivery).
📌 Features 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 on how to activate it. Here are the key steps:
1. Purchase your eSIM from an online provider (like Vostra).
2. Receive an email or check the app for 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 while traveling or manage multiple plans simultaneously without hardware constraints.

FAQ

Why is the eSIM more secure than a physical SIM card?

The eSIM is integrated directly into the device and cannot be removed or swapped like a traditional SIM card. This reduces the risks of theft or fraud through SIM card swapping (« 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, eSIM transfer depends on the operator. Some allow easy transfer via their app, while others require a new activation with a QR code.

Does the eSIM work in all countries?

The eSIM works in most countries, but it depends on the 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 are supporting eSIM, but it’s not yet universal. Before switching to eSIM, it is advisable to check if your current operator or the one at your destination supports this technology.
What are the disadvantages of eSIM compared to a physical SIM card?
Although eSIM offers many advantages, it does have some limitations:

Transfer between devices may 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?

It depends on the phone model. Most compatible smartphones allow you to store multiple 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.
