The Silent Revolution of Mobile Telephony
In the rapidly evolving mobile landscape, the advent of the eSIM represents one of the most significant innovations in recent years. This technology is gradually changing the way we connect, offering new possibilities to modern smartphone users. But the question that many ask is: can we really use a traditional SIM card and a digital eSIM at the same time? The answer is yes, and the implications are more interesting than you might imagine.
eSIM: Integrated Technology for Borderless Connectivity
Before we delve into simultaneous use, it’s important to understand what an eSIM actually is. The acronym stands for “embedded SIM,” which is a SIM that’s integrated directly into the device’s chipset. Unlike a traditional physical card that we insert manually, an eSIM is a non-removable component that’s digitally programmed to connect to a specific carrier. This feature eliminates the need to fiddle with tiny SIM cards and greatly simplifies the process of switching carriers.
Dual SIM: two numbers, one device
Dual SIM compatibility is one of the major advantages of the latest generation of smartphones. Devices that support both SIM cards and eSIMs allow users to simultaneously manage two phone numbers, two tariff plans and even two different operators. This feature has proven to be particularly valuable for those who want to separate their private and professional lives, or for those who frequently travel between different countries.
The concrete advantages of the hybrid configuration
The simultaneous use of SIM cards and eSIMs offers numerous practical advantages:
Unprecedented flexibility
Keeping your national number active while using a local data plan abroad becomes easy. This means you can receive calls and texts on your usual number while surfing with local rates.
Cost Optimization
International roaming charges can be significantly reduced or eliminated entirely. The ability to activate a local data plan via eSIM, while keeping your SIM card for calls, is an effective economic strategy for travelers.
Perfect separation between professional and personal spheres
A number dedicated exclusively to work communications and one for private life, all on the same device: an elegant solution to maintain the right balance between the different spheres of your life.

Step by step setup
The setup process for both SIMs is surprisingly simple:
Compatibility check : First of all, it is essential to make sure that your device supports dual SIM technology with eSIM. This information can be easily found in the technical specifications of the smartphone or by consulting the official website of the manufacturer.
eSIM Activation : The process requires collaboration with your telephone operator, who will provide a QR code to scan or a guided activation via a dedicated application.
Inserting the SIM Card : The traditional procedure involves turning off the device, inserting the SIM into the appropriate slot and turning the smartphone back on.
Customizing settings : Through the settings menu, the user can define which SIM to use for outgoing calls, messages and data connection. This flexibility allows you to optimize the use according to your specific needs.
Travel without worries: the international eSIM
When traveling abroad, the combination of a national SIM card and an international eSIM is particularly advantageous. This arrangement allows you to remain reachable on your usual number, while simultaneously using a local data plan that avoids expensive roaming charges. The user can thus freely access all the applications installed on the device, including those that require verification via the national telephone number.
Global solutions for demanding travellers
There are several options on the market for those looking for reliable international eSIM services. Among them, BLIVALE stands out for its global coverage that spans over 200 countries. The peculiarity of this service lies in the ability to group multiple geographic regions, ensuring seamless connectivity even when crossing different national borders.
Testimonies from the field
The effectiveness of these solutions is confirmed by the direct experiences of users from different parts of the world:
Europe
Marco Rossi, a frequent traveler who frequently moves from Italy to Asian destinations, shared his appreciation: "During my last trip to Asia, the combination of BLIVALE SIM Card and international eSIM allowed me to perfectly manage personal and professional communications. The quality of the connection remained impeccable throughout the duration of the stay, allowing me to work and stay in touch with my family without any complications."
North America
Sarah Johnson, an IT consultant from Toronto, shares her experience: "I travel regularly between Canada, the United States and Mexico for work. Previously, I used to use three different SIM cards that I had to constantly swap. Since I discovered the possibility of using my Canadian SIM and an international eSIM from BLIVALE at the same time, I have completely solved this problem. I keep my main number always active while surfing with local rates. A change that has saved me hundreds of dollars in roaming fees."
Asia
Lee Min-ho, a software developer from Seoul, explains, “My work often takes me to Japan and China. Using my Korean SIM card along with a BLIVALE eSIM for data in the countries I visit has transformed my travel experience. I no longer have to worry about finding public Wi-Fi or paying exorbitant rates. The dual SIM setup allows me to stay on the move, maintaining the same efficiency I would have in my office in Seoul.”
Middle East
Fatima Al-Mansoori, a journalist from the UAE, shares: "As a reporter, I travel frequently between Dubai, Qatar and Saudi Arabia. Using my UAE SIM and a regional BLIVALE eSIM simultaneously ensures that I can broadcast live reports without connection drops when crossing borders. Before discovering this solution, I had to deal with connectivity issues that sometimes affected my work. Now I can focus solely on my reporting."
South America
Carlos Mendoza, a freelance photographer from Argentina, says: "My profession takes me all over Latin America, often to remote areas. Having my Argentine SIM always active for important calls and simultaneously using a BLIVALE eSIM for local data connection has proven to be a winning combination. I can upload my photographs to clients' servers even from remote locations in the Amazon rainforest or the Andes, always maintaining the possibility of being contacted on my main number."
Conclusions: a trend destined to grow
The simultaneous use of SIM Card and eSIM is much more than a simple technological convenience: it is a concrete response to the connectivity needs of an increasingly global and interconnected world. The testimonies collected from users from different continents confirm how this solution is rapidly becoming essential for professionals, travelers and for anyone who needs flexible and reliable connectivity.
As smartphones continue to evolve and 5G coverage expands, we can expect this mode to become more and more widespread, further simplifying the digital lives of professionals and travelers of all nationalities.
eSIM technology is quietly revolutionizing the way we connect, offering possibilities that until a few years ago seemed futuristic. And this is just the beginning of a path of innovation that promises to make global connectivity increasingly accessible and seamless.
