eSIM for Travel and International Roaming

What is International Roaming?

International roaming, also known as roaming, is a service that allows customers to use their existing SIM card from Vietnam to make calls and access the internet in another country. When you leave Vietnam, your SIM card is outside your home carrier’s coverage area and will automatically connect to a partner network in your destination country.

After registering for international data roaming, you can easily stay in touch using your Vietnamese SIM wherever you are. This service offers several benefits:

No need to buy a new SIM card; you can continue using your existing number to communicate with family and friends.
Easy payment options, with both prepaid and postpaid plans available.
Seamless use of your SIM card abroad without complicated registration processes.

However, international roaming is often much more expensive than other options, and high data charges can quickly add up, leading to unexpectedly large bills

What is a travel eSIM?

A travel eSIM is an electronic SIM that is embedded directly into the device’s motherboard, eliminating the need for a traditional SIM card slot. eSIMs perform all the same functions as regular physical SIM cards. A travel eSIM is an international version of this technology, allowing you to access the internet every time you go abroad.

Travel eSIMs offer many advantages, such as:

Easy registration and activation via QR code without the need to purchase or wait for shipping
No need to remove or replace SIM cards, saving time and avoiding the risk of losing or breaking your SIM
Reasonable costs with a wide variety of usage plans
Fast connectivity as soon as you arrive at the airport

Travel eSIM vs International Roaming: Which Is the Cost-Effective Solution for Travelers?

Both travel eSIM and international roaming are popular services for those going abroad. However, readers should carefully consider which method is more suitable for their needs.

To save on costs, travel eSIM is always a top choice thanks to its variety of plans, affordable prices, and especially the benefit that when you use up your high-speed data, you are switched to a lower speed without incurring any additional charges.

On the other hand, international roaming tends to be quite expensive. If you are a postpaid subscriber and forget to turn off data roaming while traveling, you may return home to a huge bill. Roaming charges vary depending on the carrier.

Therefore, to choose a method that fits your budget, travel eSIM remains the optimal solution. With modern technology and many outstanding advantages, eSIM is now a new trend in the telecommunications industry that you should not overlook.

Saving Costs on International Travel: The Future Role of Travel eSIM

Traveling abroad no longer means dealing with expensive roaming charges or the inconvenience of buying local SIM cards at every destination. With travel eSIMs, you can activate a data plan instantly, enjoy seamless internet access, and manage your expenses more efficiently throughout your journey.
