Coverage and networks

This Asia eSIM covers 7 countries in Southeast Asia: Thailand, Vietnam, Cambodia, Malaysia, Singapore, Indonesia and the Philippines. In each country it uses local partner networks, such as Telkomsel on Bali and across Indonesia, Viettel in Vietnam, Globe in the Philippines, Singtel and M1 in Singapore, Maxis and CelcomDigi in Malaysia, the True network (TrueMove H and DTAC) in Thailand and Metfone in Cambodia. In six of the seven countries you get 5G where the network offers it, while in Cambodia the eSIM runs on 4G. Laos, Myanmar and Brunei are not included, and neither are Japan, China or South Korea. Networks: Telkomsel, Viettel Mobile, Globe, SingTel, Maxis, CelcomDigi, TrueMove H, Metfone.

A multi-country trip through Southeast Asia typically uses 1 to 2 GB per week for maps, Grab rides and messaging, so 5 to 10 GB suits most two to four week trips. If you work online on the road, take 20 GB, and if you travel for longer than a month, the 50 GB bundle is the only one that stays valid beyond 30 days.

None of these seven countries fall under EU roaming rules, so EU travellers cannot rely on roam-like-at-home here, and most home plans charge extra for data in Southeast Asia. If your route also includes Laos, add a separate eSIM for it, because this bundle does not work there.

Included countries (7)

Frequently asked questions

Does an eSIM work in Asia?

Yes. Our eSIM gives you instant mobile data in Asia on the local networks, with no roaming fees. Your phone needs to support eSIM and be carrier-unlocked.

How much data do I need for Asia?

It depends on your trip. For mostly maps and messaging, 1 to 3 GB is plenty. If you use navigation, social media and some streaming, plan for roughly 1 GB every two to three days.

How fast do I get my eSIM?

Right after payment. You receive a QR code on screen and by email immediately. It is best to install it at home over Wi-Fi before you leave.

Do I keep my own phone number?

Yes. Your own SIM stays in your phone for calls and texts. The eSIM runs alongside it, purely for mobile data in Asia.

What is the cheapest eSIM for Asia?

The cheapest eSIM for Asia at esimzu starts from €2,99, with a lowest-price guarantee. You pay in euros by Bancontact, card or crypto and receive the eSIM instantly by QR code, with no app or physical SIM card.

Which countries does this Asia eSIM cover?

Seven countries in Southeast Asia: Thailand, Vietnam, Cambodia, Malaysia, Singapore, Indonesia (including Bali) and the Philippines. Laos, Myanmar, Brunei and Timor-Leste are not included, and neither are countries further afield such as Japan, South Korea and China.

What happens when I travel from Thailand to Vietnam or Bali?

Nothing you need to manage. After landing or crossing the border, your phone automatically finds a partner network in the new country, usually within a few minutes of turning off airplane mode. Your remaining data carries over, because it is one shared allowance for all seven countries.

Does the eSIM work on the islands?

On busy islands such as Bali, Phuket, Koh Samui, Langkawi and Phu Quoc you generally get 4G in the towns and around the hotels through the local partner network. On small remote islands and during boat trips the signal can drop out, just as it would with a local SIM.

Is this bundle better than a separate eSIM per country?

It depends on your route. Per GB, a single-country eSIM is often cheaper, sometimes even when you buy one for each of two countries. The regional bundle is about convenience: one purchase, one installation and one allowance you can spread freely across all seven countries, with no data left unused on a country eSIM if your plans change on the road.
