Asia 13 Countries eSIM: One Plan for Multi-Country Travel in Asia

One eSIM for 13 Destinations Across Asia

Planning a multi-country trip around Asia sounds exciting.

Buying and setting up a new SIM card at every destination? Not so much.

You might begin your trip in Japan, continue to Taiwan, spend a few days in Hong Kong, and then fly to Thailand, Vietnam, or Singapore. With separate local SIM cards, each new destination can mean another purchase, another installation, and another plan to manage.

A regional Asia 13 Countries eSIM keeps things much simpler.

You install one eSIM before your trip and use the same plan across all 13 supported destinations. Your phone connects to available partner networks as you travel, so you do not need to install a new eSIM each time you cross a border. Datapang classifies this as a roaming eSIM, meaning it uses supported roaming networks to provide connectivity across multiple destinations.

Which Countries Are Included?

The Datapang Asia 13 Countries eSIM currently covers:

• Thailand

• Indonesia

• Singapore

• Taiwan

• Japan

• Laos

• China

• Cambodia

• Malaysia

• Philippines

• Hong Kong

• Macau

• Vietnam

The plan does not currently include South Korea, Myanmar, India, Nepal, or Sri Lanka. Travelers visiting destinations outside the supported list will need a separate local or regional eSIM.

How Does the Asia 13 Countries eSIM Work?

The Asia 13 Countries eSIM is installed digitally on an eSIM-compatible smartphone.

After purchasing your plan, Datapang sends an eSIM QR code to the email address used during checkout. You scan the code while connected to Wi-Fi and add the eSIM to your phone. Datapang recommends installing it around one day before departure and selecting it for mobile data after you arrive at your destination.

Once connected, you can use mobile data for:

• Google Maps and other navigation apps

• Translation apps

• WhatsApp, LINE, Messenger, and KakaoTalk

• Transportation and ride-booking apps

• Hotel and flight reservations

• Restaurant and attraction searches

• Social media

• Email and remote work

When you enter another supported destination, your phone should search for an available partner network. You normally do not need another QR code or a second eSIM installation.

Why Choose One Regional eSIM?

One Installation

You only need to install and manage one eSIM profile throughout your trip.

This is especially helpful when visiting several destinations over a short period.

No Physical SIM Swapping

Your regular SIM card can remain inside your phone.

There is no need to open the SIM tray, store several tiny SIM cards, or worry about losing your original SIM while traveling.

Easier Border Crossings

You do not need to search for a SIM shop immediately after every flight, train journey, or border crossing.

Your phone can connect to supported networks in each covered destination using the same regional plan.

Keep Your Regular Number

On a Dual SIM-compatible phone, you can keep your home SIM active while using the Datapang eSIM for mobile data.

Your regular carrier may still charge for traditional calls, SMS, or roaming activity, so make sure the Datapang eSIM is selected as your mobile data line.

One Plan to Manage

Instead of tracking multiple activation dates, QR codes, data balances, and expiration periods, you manage one regional plan for the entire journey.

Asia 13 Countries eSIM Plan Options

Datapang currently offers Daily and Unlimited options for the Asia 13 Countries eSIM.

Daily 500MB

You receive 500MB of high-speed data each day. After reaching the daily allowance, your connection continues at a reduced speed until the next reset.

This option works well for:

• Maps

• Messaging

• Email

• Translation

• Essential browsing

• Travelers who regularly use hotel or café Wi-Fi

Daily 1GB

You receive 1GB of high-speed data each day, followed by reduced-speed data after reaching the daily allowance.

This option is suitable for:

• Regular navigation

• Messaging

• Social media browsing

• Music streaming

• Occasional photo uploads

Daily 2GB

You receive 2GB of high-speed data each day, followed by reduced-speed data.

This may suit travelers who frequently use:

• Instagram and Facebook

• Video calls

• Transportation apps

• Photo uploads

• Regular mobile browsing

Daily 3GB

You receive 3GB of high-speed data each day before the speed is reduced.

This option is better for:

• Uploading travel content

• Travelers who use less public Wi-Fi

Unlimited 5GB

The Unlimited plan provides 5GB of high-speed data, followed by unlimited data at 1Mbps for the remainder of the validity period.

At 1Mbps, you can generally continue using maps, messaging, email, and basic browsing. High-resolution streaming, large uploads, and demanding video calls may feel slower after the initial high-speed data is used.

Current validity options vary by plan and include periods from one day up to 30 days.

Which Plan Should You Choose?

Choose Daily 500MB if:

• You mostly use mobile data for maps and messaging.

• You use maps throughout the day.

• You regularly check social media.

• You send photos and occasionally stream music.

Choose Daily 2GB if:

• You post Instagram Stories regularly.

• You make occasional video calls.

• You want enough data without constantly checking your balance.

Choose Daily 3GB if:

• You upload content frequently.

• You watch videos while traveling.

• You use mobile data as your main internet connection.

Choose Unlimited 5GB if:

• You want your connection to continue after the high-speed allowance is used.

• Your main priority is always having access to maps and messaging.

• You are comfortable with reduced speed after using the first 5GB.

Sample Multi-Country Itineraries

Japan, Taiwan, Hong Kong and Macau

A regional eSIM works well for a trip such as:

• Tokyo

• Osaka

• Taipei

• Hong Kong

• Macau

You can use the same eSIM throughout the journey instead of purchasing separate plans for Japan, Taiwan, and Hong Kong/Macau.

Thailand, Vietnam, Cambodia and Laos

This is a popular route for backpackers and long-term travelers:

• Bangkok

• Chiang Mai

• Ho Chi Minh City

• Hanoi

• Phnom Penh

• Siem Reap

• Vientiane or Luang Prabang

One regional eSIM helps keep your navigation, booking apps, and messaging connected throughout the trip.

Singapore, Malaysia and Indonesia

For a shorter Southeast Asia itinerary:

• Singapore

• Kuala Lumpur

• Penang or Langkawi

• Bali or Jakarta

You can continue using the same eSIM while moving between all three destinations.

China, Hong Kong, Macau and Taiwan

Travelers visiting several Chinese-speaking destinations can use the plan across:

• Mainland China

• Hong Kong

• Macau

• Taiwan

Before traveling to China, remember that access to certain websites and apps may be affected by local internet regulations.

How Much Data Do You Need?

Your data needs depend more on your phone habits than the number of countries you visit.

Light User

You mainly use:

• Maps

• WhatsApp or LINE

• Translation

• Email

• Occasional web searches

Consider Daily 500MB or Daily 1GB.

Regular Traveler

You use:

• Navigation throughout the day

• Instagram and Facebook

• Music streaming

• Booking and transportation apps

• Occasional photo uploads

Consider Daily 1GB or Daily 2GB.

Heavy User

You frequently use:

• TikTok and YouTube

• Video calls

• High-resolution photo and video uploads

• Cloud backups

• Mobile hotspot

Consider Daily 3GB or another plan with a larger high-speed allowance.

Remember that video streaming, hotspot use, cloud syncing, and uploading travel videos can consume data much faster than maps or messaging.

What to Do When You Arrive

Datapang’s troubleshooting guidance recommends confirming that roaming is enabled, selecting the correct eSIM for mobile data, and restarting the device when connection problems occur.

A data-only eSIM provides the internet connection WhatsApp needs. Your WhatsApp account normally remains linked to the phone number you originally registered.

You can continue using:

• Video calls

• Group chats

• Photos and voice notes

You do not need to change your WhatsApp number simply because you are using a travel eSIM for mobile data.

Can You Make Regular Calls or Send SMS?

The Asia 13 Countries eSIM is listed as a data-only product.

It does not provide traditional voice calls or SMS unless otherwise stated in the selected product details. You can still use internet-based calling apps such as WhatsApp, LINE, Messenger, FaceTime, Telegram, Zoom, or Google Meet.

What Happens When You Cross a Border?

You normally keep the same eSIM turned on.

After entering another supported destination:

• Wait a few minutes for your phone to find a partner network.

• Toggle Airplane Mode if the signal does not appear.

• Confirm that the Datapang eSIM is still selected for mobile data.

• Restart your phone if necessary.

Do not delete the eSIM while traveling. Most eSIM profiles cannot be reused after deletion unless customer support is able to reissue them.
