In an increasingly connected world, understanding the technologies that keep us online is essential. Find out everything you need to know about the differences between traditional SIMs and international eSIMs.
Introduction to eSIM Technology
In the digital age we live in, staying connected is no longer a luxury but a daily necessity. Whether you are traveling for work, exploring new countries or simply want a reliable connection, mobile connectivity technologies are essential. Among these, the revolutionary eSIM technology is quickly gaining ground over traditional SIM Cards.
But what exactly are eSIMs, and how do they differ from the SIM cards we’ve been using for decades? This article will explore both technologies in detail, helping you understand which is the best solution for your connectivity needs.
What is a Traditional SIM Card?
The traditional SIM (Subscriber Identity Module) is a small removable card that we insert into our mobile devices. It contains a microchip that stores user information, including:
The phone number
Personal contacts
Text messages
Telephone operator information
SIM cards were introduced in the 1990s and revolutionised the way we use mobile phones, allowing users to easily transfer their number and data from one device to another.
Over the years, SIM cards have shrunk considerably in size, from the standard SIM to the micro-SIM, up to the current nano-SIM, but the basic concept has remained unchanged: a physical card that must be inserted into a dedicated slot on the device.
The eSIM Revolution: What It Is and How It Works
The eSIM (embedded SIM) is the natural evolution of SIM technology. Unlike its physical counterpart, the eSIM is integrated directly into the device during manufacturing. It is not a card to be inserted or removed, but a programmable chip soldered to the motherboard of the device.
This tiny chip can store multiple carrier profiles, allowing users to switch between carriers without having to swap out a physical card. The process is completely digital and can be managed through the device settings or through dedicated apps.
SIM vs eSIM: The Key Differences
1. Physical Form
Traditional SIM : It is a removable physical card that must be inserted into a special slot on the device.
eSIM : It is a chip integrated directly into the device, not removable and not visible externally.
2. Activation and Configuration
Traditional SIM : Requires the purchase of a physical card, often with a visit to an operator store or receiving it by post.
eSIM : It can be activated by scanning a QR code or through an app, without the need for physical components. The entire process can be completed in a few minutes, wherever you are.
3. Change Operator
Traditional SIM : To change operator you need to remove the old SIM and insert a new one.
eSIM : Allows you to change operators via software, without the need for additional hardware. It also allows you to store profiles for multiple operators at the same time.
4. Compatibility with Devices
Traditional SIM : Compatible with most mobile devices produced in the last few decades.
eSIM : Compatibility is limited to newer devices. However, more and more manufacturers are incorporating this technology into their new models.
5. Resilience and Durability
Traditional SIM : Can be damaged, lost or stolen. It is subject to physical wear and tear.
eSIM : Being integrated into the device, it cannot be lost or damaged separately. It has a theoretical lifespan equal to that of the device itself.
6. Dual SIM
Traditional SIM : To have two numbers you need a device with a dual SIM slot or use a hybrid SIM.
eSIM : Allows you to have an eSIM plus a traditional SIM, or in some cases multiple eSIMs, allowing the use of multiple numbers without additional hardware.
7. National SIM Cards vs International eSIMs
National SIM Cards :
They work mainly in the operator's home country
When used abroad, they activate expensive international roaming
They require physical replacement with local SIMs to avoid high costs abroad
They are linked to a single national operator
They often offer pricing plans optimized for home use only
International eSIMs :
Specifically designed for use in multiple countries
They allow you to activate local data plans without changing the physical card
They offer competitive rates compared to traditional roaming
They allow you to keep your main number active while using a local data connection
They often include multi-country or regional packages (e.g. Europe, Asia, etc.)
Allows you to add data on-demand when needed
Ideal for those who frequently cross national borders
8. Costs and Pricing Plans
Traditional SIM Cards :
National plans are generally inexpensive for home use.
International roaming costs often high and not very transparent
They require the purchase of local SIMs (with activation costs) in each country visited
Often tied to long-term contracts
International eSIMs :
Flexible plans based on travel duration (1 day, 1 week, 1 month)
Transparent rates with no hidden costs
Unlimited data options for intensive travellers
Payment only for the period actually needed
No activation or deactivation costs
Possibility to pre-purchase packages before departure
9. Activation Process Abroad
Traditional SIM Cards :
Need to find a physical store in the destination country
Potential language barriers when purchasing
Request for identity documents in many countries
Time wasted during vacation or business trip
International eSIMs :
Activation possible before departure
Instant connection upon arrival, without looking for a store
Completely digital procedure in Italian language
No physical documents required

Instant Activation : You can activate a local data plan before you even arrive at your destination.
Keeping Your Original Number : You can keep your main number active to receive calls and SMS, while simultaneously using a local data plan.
Flexibility : Ease of switching between operators based on the country visited, without having to search for physical stores.
Sustainability : Reducing the use of plastic for SIM cards contributes to a lower environmental impact.
