Have you ever thought about traveling abroad without worrying about exorbitant roaming charges? International eSIMs seem like the perfect solution to stay connected wherever you are. But there's a question many travelers ask: do international eSIMs work for voice calls, in addition to data?
The answer may surprise you and completely change the way you plan your travels.
What Are International eSIMs and How Do They Work?
eSIMs (embedded SIMs) are the evolution of traditional physical SIM cards. Integrated directly into modern devices, they allow you to activate phone plans without having to insert a physical card .
International eSIMs are specifically designed for frequent travelers, offering data coverage in multiple destinations with a single digital solution. But when it comes to voice calls , things get more complicated.
The Truth About Voice Calls with International eSIMs
The Data Only eSIM Limit
Here’s the reality that many providers prefer not to highlight: most international eSIMs are designed exclusively for data . This means that:
They do not support traditional voice calls
They do not allow sending traditional SMS
They are optimized for internet connectivity
This technical limitation arises from the fact that international eSIMs use simplified roaming agreements that often exclude voice services to reduce operating costs.
Why Local eSIMs Are Different
Local eSIMs , on the other hand, offer all the services of a traditional SIM because:
They operate directly on the local network
Includes voice, SMS and data
They retain all the telephone functionality
However, choosing a local eSIM has its disadvantages:
High roaming costs if you travel to other countries
International rates for calls abroad
Complex management of multiple eSIMs for different countries
The Consequences of Traditional Roaming Charges
When you use a local eSIM abroad, you expose yourself to:
Prohibitive Roaming Costs
Rates that can reach 15-20 euros per MB
International calls up to 3-5 euros per minute
International SMS at 0.50-1 euro each
Bills Shock
Many travellers have found themselves charged hundreds of euros for just a few days of unknowingly using roaming.
