introduction

Traveling to Asia is a dream come true for many people. From the busy streets of Tokyo to the peaceful beaches of Thailand, Asia is full of unforgettable experiences. But staying connected while you travel can be hard and expensive—unless you use a travel eSIM.

In this 2025 guide, we will explain why every traveler needs a travel eSIM in Asia, how it works, and even how it can help with important things like finding a dentist that accepts Medicaid while you’re abroad.

What Is a Travel eSIM?

A travel eSIM is a small digital SIM card that works on your phone. You don’t need to insert anything—just scan a code, and you’re connected. It’s fast and easy to set up, and you can use it in many countries without changing your SIM card.

If you’re going to Asia, using a travel eSIM is one of the smartest things you can do.

Why Travelers Should Use a Travel eSIM in Asia

There are many reasons why travelers love using travel eSIMs, especially in Asia:

Stay Connected Everywhere

With a travel eSIM, you can use the internet, make calls, and send messages without paying expensive roaming fees. Whether you’re in a city or a rural village, many eSIM providers offer great coverage across Asia.

No More SIM Swapping

Changing physical SIM cards in every country can be a hassle. With a travel eSIM, you don’t need to do that. Just pick your plan and connect.

Affordable Data Plans

Many eSIM plans are cheaper than traditional roaming. You can buy plans for one country or several. For example, if you’re visiting Japan, South Korea, and Vietnam, you can choose a regional eSIM plan that works in all three.

Great for Emergencies

If something goes wrong, like needing a doctor or dentist that accept Medicaid, you’ll be glad you have fast internet to search for help.

How a Travel eSIM Can Help You Find Healthcare, Including a Dentist That Accept Medicaid

Many travelers forget about medical needs while planning trips. But what if you get a toothache in the middle of your vacation?

Thanks to your travel eSIM, you can quickly look up clinics or a dentist that accept Medicaid (if you’re in U.S. territories or in case of emergencies handled through travel insurance). Having internet access gives you peace of mind when searching for healthcare services.

What Is Dentist Medicaid?

If you’re from the United States and you’re on Medicaid, you may already know about dentist Medicaid services. Medicaid covers dental services for all children enrolled in the program. These services are part of a full set of health benefits called Early and Periodic Screening, Diagnostic, and Treatment (EPSDT).

This means kids can get regular check-ups, cleanings, and even emergency dental care under dentist Medicaid. Though adult coverage depends on your state, knowing that Medicaid can help is still important—even while traveling.

Can Medicaid Help While Traveling in Asia?

While Medicaid doesn’t usually cover care outside the U.S., your travel eSIM can help you:

Contact your insurance company
Find dentist that accept Medicaid if you’re in U.S. territories like Guam
Use telehealth services that are covered by Medicaid
Search for nearby clinics and hospitals online

Without an eSIM, this would be very hard to do.

Best Places in Asia to Use a Travel eSIM

Using a travel eSIM is helpful almost anywhere in Asia, but here are some of the best places where it really shines:

Japan

Japan has excellent internet services, and most cities have full 5G coverage. Use your eSIM to navigate trains, translate menus, or book tours online.

Thailand

Whether you’re on the beach in Phuket or exploring temples in Chiang Mai, your travel eSIM will keep you connected and safe.

Vietnam

Travelers love Vietnam’s street food and history. An eSIM helps you order taxis, find hotels, and keep in touch with family.

South Korea

From K-pop concerts to street shopping in Seoul, your eSIM lets you share photos and get around with ease.

How to Get a Travel eSIM for Asia

Getting a travel eSIM is simple:

Check if your phone supports eSIMs. Most new phones do.
Choose an eSIM provider. Look for plans that work in Asia.
Buy a plan and scan the QR code. It will install your eSIM automatically.

Important Tips When Using a Travel eSIM

Download offline maps before you leave, just in case.
Use Wi-Fi when you can to save data.

Use the eSIM to check for health services if you need them, including those covered by dentist Medicaid or Medicaid-approved providers in territories.
