What is eSIM? Can eSIM Make Calls?

eSIM stands for Embedded SIM. It is an electronic SIM with an extremely small size, soldered directly onto the device’s motherboard during manufacturing and cannot be removed.

To answer the question, "Can eSIM make calls?"—the answer is both yes and no. For eSIMs converted from a physical SIM with a regular phone number, users can still make and receive calls and send messages just like with a physical SIM, without any interruption. However, there is also a type of Data eSIM, designed specifically for internet connectivity while traveling, which does not support calling functions.

How Many Types of eSIM Are There?

eSIM users should distinguish between two types of eSIM: regular eSIM and Data eSIM.

Regular eSIM

This type of eSIM is converted from a physical SIM and used as a phone number with the same functions as a physical SIM installed in a phone. This SIM type fully supports calling, messaging, and storing plans.

Data eSIM
This type of eSIM is used for internet access when traveling abroad, also known as travel eSIM. It is commonly used for short-term travel in other countries. This eSIM does not support regular calling functions but only provides internet access.

However, with the development of social media platforms today, you can still make calls using apps like Messenger, Zalo, Viber, etc., as long as you have an internet connection.

Advantages of Using Travel eSIM

Travelers prefer eSIMs because they are easy to purchase and activate via QR code, eliminating the hassle of swapping physical SIM cards and allowing immediate internet access upon landing, without worrying about roaming charges. Additionally, eSIMs reduce the risk of losing or breaking a physical SIM during the process of changing or installing SIM cards.

In conclusion, eSIM technology is revolutionizing the way travelers stay connected during international trips. With its convenience, flexibility, and ease of activation, eSIM eliminates the hassle of swapping physical SIM cards and helps avoid expensive roaming fees. For international travelers, eSIM not only ensures instant internet access upon arrival but also reduces the risk of losing or damaging a SIM card. Leading eSIM brands such as eSIMONE.com, eSIMGlobal.org, eSIMdulich.com, Airalo, Holafly, and Get Nomad offer reliable service and a variety of data packages to suit different travel needs. Choosing a reputable eSIM provider allows travelers to enjoy seamless connectivity, making every journey safer, more convenient, and worry-free.
