Do you own an Apple device and are considering activating an eSIM? You’ve come to the right place! With a compatible iPhone, adopting this technology is a breeze. In this article, we’ll help you understand Dual SIM, discover what it brings to your device, and learn how to easily activate an eSIM on iPhone.

What is Dual SIM technology?

Dual SIM technology allows you to combine multiple mobile lines (physical or virtual via eSIM) on a single device, so you can connect to two different networks simultaneously.

This way, you can easily manage a professional and a personal number, or effortlessly switch between different local plans when you travel.

In practice, some smartphones can accommodate two physical SIM cards. Others combine a traditional SIM card with an eSIM, while some more advanced models will even allow you to store multiple eSIMs at once. This flexibility offers true freedom, adapted to your lifestyle and professional needs.

Dual SIM on iPhone: how does it work?

Starting with iPhone XR, Apple integrated Dual SIM technology, allowing you to simultaneously use a physical SIM card and/or an eSIM (depending on local compatibility). Thanks to this feature, you can:

• Separate your voice and data usage: keep your main line for calls and texts and opt for an eSIM dedicated to mobile internet.
• Subscribe to a local plan when you travel without having to remove your main SIM.
• More easily manage personal and professional life by keeping a distinct number for each.

A small clarification: your iPhone must be unlocked to benefit from two plans from different operators. If it is locked, make sure your two offers come from the same provider to activate Dual SIM.

Is your iPhone compatible with eSIMs?

To activate an eSIM on your iPhone, you need at least an iPhone XR (running iOS 12 or later). Here’s how to quickly check if your device is compatible (note that these steps may vary depending on the iOS version):

1. Open Settings, click on « Cellular » or « Mobile Data ».
2. Select « Cellular Data ».
3. Look for the « Add eSIM » or « Add Cellular Plan » option.

If you see one of these options, your iPhone is eSIM-ready! Otherwise, check our full list of compatible devices.

Also keep in mind that some iPhone models do not support eSIM and that your iPhone must be unlocked to be able to use an eSIM from another operator.

Staying connected while traveling is a smart choice, but not always straightforward. Between Wi-Fi, data plans, and roaming charges, it’s easy to get confused. Today, we’re expanding your horizons with a new alternative: the eSIM.

An eSIM is a digital SIM card directly integrated into your device, allowing you to connect instantly, at a lower cost, wherever you are in the world. But why choose an eSIM when nano SIMs already exist?

That’s where we come in. Discover in detail what differentiates the eSIM from the nano SIM and which solution is best suited to your needs.

The Evolution of the SIM Card

At the dawn of the mobile phone era, SIM cards were almost as large as bank cards, just like the devices themselves, which were bulky and cumbersome!

Since then, miniaturization has done its work: first with micro SIMs, then with nano SIMs, which are 40% smaller, and finally eSIMs, reduced to a tiny chip of just 2.5 mm x 2.3 mm.

Yet, despite this incredible size reduction, the basic technology remains unchanged. The SIM card remains a memory chip containing your user information, essential for accessing the mobile network.

In short, the smaller the SIM gets, the more space it frees up in your devices, allowing for example to integrate a more powerful battery or to design ever thinner and more elegant phones.

What is a nano SIM card?

Today, nano SIMs represent the most compact physical SIM card format on the market. They have become the essential standard, integrated into the majority of current smartphones.

However, there is no indication that this is the ultimate evolution of SIM cards as we know them today.

What is an eSIM?

The eSIM, on the other hand, pushes the boundaries of the traditional SIM card concept by eliminating the hardware constraint. Instead of inserting a card into a tray with a needle, the eSIM chip is directly integrated into the device. You then simply download your plan to connect to the network.

While some models still have a slot for a physical card in addition to the eSIM, many recent smartphones now rely solely on this integrated solution.

eSIM vs nano-SIM: More Similarities Than You Imagine

We often tend to pit classic SIM cards against eSIMs, as if they were incomparable. You might be surprised to learn that they share many common points:

• They connect your device to your mobile operator’s network.
• They are used on a multitude of devices, not just smartphones.
• They identify your phone and ensure the correct plan is applied.
• In a Dual SIM mobile, they work together.
• Ultimately, they are both… SIMs!

The distinction? The eSIM is directly integrated into the phone and downloads your plan remotely, whereas the classic nano-SIM requires a physical card. Beyond this difference, both technologies indeed fulfill a similar function.

eSIM vs. nano SIM: which is the better option?

It all depends on how you plan to use your smartphone. Before deciding, here’s a quick overview of each’s strengths.

Advantages of the nano SIM

Introduced in 2012, the nano SIM is now a proven standard. This longevity offers several advantages 👇:

• Easy to acquire : Present in almost all recent smartphones, the nano SIM is easily found, provided of course you remain vigilant against scams targeting travelers.
• Simplified transfer from one device to another : As long as your SIM card and phone are not locked, simply remove it and insert it into a new device. It’s that simple!
• Local number in a flash : Need a local phone number for calls and SMS during an overseas trip? Pop a nano SIM into your device and you’re all set.

Advantages of the eSIM

The eSIM revolutionizes your mobile experience: directly integrated into your smartphone, it eliminates the constraints of physical SIM cards. Changing operators becomes child’s play, and activating a new data plan is done in a few clicks. Some of these qualities👇:

• Unparalleled flexibility : Save up to 15 to 20 eSIM profiles on your phone and easily switch from one to another, depending on your needs or destinations.
• Keep your usual number : If your device is equipped with a dual SIM (physical + eSIM), continue to use your traditional number for calls. Otherwise, simply opt for WhatsApp, Telegram, or other messaging apps to stay reachable.
• Integrated regional plans : Some eSIM subscriptions offer you coverage in multiple countries. Perfect for travelers who want to stay connected without changing cards at every border.
• Impossible to lose : Unlike a physical SIM card, an eSIM remains stored on your phone’s chip. You no longer risk losing your plan or compromising your connection.

Enjoy the flexibility of Dual SIM with eSIM and nano-SIM

Did you know you can use an eSIM alone or combine it with a nano-SIM in the same phone? This combination, called Dual SIM, offers you unparalleled flexibility. There are two types of Dual SIM:

1. Dual SIM Dual Standby (DSDS)
   With DSDS mode, you simply choose which SIM card handles your calls and messages. When traveling, for example, you can keep your nano-SIM for rare SMS or calls (such as multi-factor authentication) while still using your eSIM’s data.
2. Dual SIM Dual Active (DSDA)
   DSDA technology goes further: your eSIM and nano-SIM are both active simultaneously. This means you can receive calls and SMS on both your numbers and switch between operators in case of an unstable network. This solution is ideal for staying reachable on both a local and an international number. Be aware, however, that this increased versatility consumes more battery.

Ultimately, the key is to find the configuration that best suits your needs.

Want to stay connected anywhere in the world without the hassle of a physical SIM card? It’s now possible! Thanks to eSIMs, travel light and enjoy international connectivity in just a few clicks.

With an eSIM, you just need to purchase a plan via the Vostra app, then scan a QR code, download it manually, or install it directly on your compatible smartphone. And just like that: you’re ready to communicate as if you were home, with no extra hardware!

You’re probably wondering if the procedure is really that simple, especially when traveling abroad? We get it: eSIM technology has really only taken off in recent years. If you want to know how your international eSIM actually works, you’ve come to the right place. Below, we’ll reveal everything about this small revolution that’s simplifying travelers’ lives.

What is an eSIM for international travel?

Planning to travel abroad and looking to stay connected without breaking the bank? Between international plans with exorbitant rates and data generously offered… in 2G, the task can seem complicated. Relying on Wi-Fi? Why not, but beware of security vulnerabilities, and it’s far from accessible everywhere.

Fortunately, if your phone is relatively new, you might already have a clever option: eSIM.

An eSIM (« embedded subscriber identity module ») is a chip integrated into your smartphone’s circuitry, which replaces the traditional SIM card with simple software to provide data service. Its strength? You can change operators or plans as often as you like, without juggling physical cards. Simply go to a dedicated platform like Vostra, then choose the subscription that suits your needs and the duration of your trip.

Particularly convenient when abroad, the eSIM doesn’t require you to remove your main SIM. It simply remains deactivated (unless you opt for dual SIM mode). Once you’re back, you just switch back to your usual SIM card as if nothing happened.

How do international eSIMs work?

eSIMs offer a clever solution to enjoy mobile data abroad without breaking your budget or frantically searching for a local SIM card upon arrival. Instead of physically replacing your usual SIM card, you simply select a plan via an app like Vostra. Then, you’ll need to follow a few simple steps to activate this new plan on your smartphone.

Specifically, the eSIM relies on local service providers that offer dedicated prepaid plans. Vostra, for its part, gathers these plans in one place to make your life easier.

Using an eSIM is very similar to using a local SIM card, with the difference that you keep your usual number (if your phone supports dual SIM, which is the case for most eSIM-compatible devices). Without this dual SIM functionality, you will still have data access and can make calls or send messages via WhatsApp, Telegram, and other online applications.

Why choose an eSIM over a local SIM card? The advantages that will convince you

Local SIM cards remain very popular with travelers abroad, but they are not the only ones generating interest. Indeed, a 2019 study reveals that 60% of consumers would adopt an eSIM service if it were offered to them. And for good reason: international eSIMs offer significant advantages over traditional SIMs.

Regional plans rather than national ones

If you travel through several countries, there’s no need to change your SIM card at each border. eSIM plans covering an entire region will accompany you throughout your journey.

Transparent local rates

On platforms like Vostra, you know exactly what you’re buying and what you’re paying for. In a store, even at an airport, it’s sometimes less clear!

Pre-purchase your data

No need to chase a SIM as soon as you land. Simply activate your eSIM data plan and immediately enjoy your phone.

Multiple plans on a single device

No more hassle of physical SIMs piling up. Most smartphones allow storing multiple eSIM plans, which greatly simplifies your organization.

Flexible durations according to your needs

Rather than committing to a full month to use only a fraction of the data, opt for the flexibility of eSIMs. Choose the data amount and duration that truly suit you.

In short, international eSIMs are increasingly becoming the ideal solution for traveling light, staying connected at lower costs, and avoiding the stress of changing SIMs at each step.

Conquer the world with peace of mind thanks to international eSIM

Now that you understand how it works, you are armed with a valuable ally for your next trip. In the blink of an eye, say goodbye to connection hassles and unexpected costs: eSIMs guarantee you total freedom in over 200 destinations supported by Vostra.
