In which Asian countries does the eSIM work?

It covers Thailand, Japan, South Korea, Vietnam, Singapore, Indonesia, Malaysia, the Philippines, Cambodia, Hong Kong, Taiwan and others. The full list is available on the plan page.

Do I have to do anything when I change country?

No, the switch is completely automatic. When you land in a new country, your phone connects to the best local network without you having to change any settings.

What is the connection speed in Asia?

In big cities such as Seoul, Tokyo and Singapore the speed is excellent, with widespread 5G coverage. In most tourist destinations 4G/LTE guarantees smooth browsing and stable video calls.

Can I keep my Italian number active?

Absolutely. The Datiovunque eSIM uses your phone's second SIM slot: your Italian number stays active for calls and SMS, while data travels on the eSIM.

How much does an eSIM for Asia cost?

eSIM plans for Asia start from €4.99. You pay once for the amount of data you choose — no subscription, no monthly fees and no hidden roaming charges. Plans with more data or longer validity cost more.

Is an eSIM or roaming better in Asia?

A local eSIM in Asia is almost always much cheaper than the roaming of your Italian operator. In the European Union roaming is often already included ("Roam Like at Home"), but outside the EU the costs can be very high — with an eSIM you know the price in advance and pay only for the data plan you need.

Should I activate the eSIM before or after I leave?

Install the eSIM at home, on Wi-Fi, before you leave. The data plan then activates automatically when you connect in Asia. That way you are online as soon as you arrive, without looking for airport Wi-Fi or buying a local SIM.

Can I top up or renew the plan for Asia?

Yes. When the data runs out or the validity expires, just buy a new plan — the eSIM profile already installed is kept and does not need to be installed again. You stay connected without interruption.

Can I share the connection (hotspot) in Asia?

Yes. You can share the connection in Asia through a personal hotspot with a computer, tablet or other devices. Shared data is deducted from your plan, so allow a few extra gigabytes if you expect to use the hotspot often.

How many GB do I need for Asia?

For a normal trip, 1–3 GB a week is enough for maps, messages and occasional browsing. With social media and photo sharing allow about 5 GB; for streaming, video calls or a hotspot count on 10 GB or more. If the volume is not enough, you can buy an additional plan at any time.

Is the eSIM compatible with my phone?

The eSIM works with all compatible devices — including iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. The phone must also be free of operator locks (not blocked). You can check compatibility in the settings under "Mobile data", or by dialling *#06# to see whether an EID code is shown.

25 countries in this region

The golden temples of Bangkok, the skyscrapers of Tokyo, the terraced rice fields of Bali, the night markets of Taipei — Asia is a continent that wins you over with its diversity. For Italians it is one of the most sought-after destinations: from adventure trips in Vietnam to luxury stays in the Maldives. But moving between Asian countries often means finding local SIMs with incomprehensible languages, required documents and waiting times on arrival. With the Datiovunque eSIM for Asia, a single plan covers the main countries of the continent: you install it before departure and it works from the moment you land.

Why use an eSIM in Asia

Asia is the continent of distances and differences: different languages, different alphabets, different transport systems in every country. Having a reliable data connection is not a luxury, it is a necessity. Grab and Bolt for taxis, Google Translate for communicating, offline and online maps for finding your way — everything depends on the connection. Buying local SIMs at the airport is possible, but often copies of the passport are needed, the staff do not speak Italian and tourist rates are not always transparent. With Datiovunque, you set up the eSIM before the trip and on your first landing — whether it is Bangkok, Seoul or Singapore — the connection is already active. Moving from one country to another, the phone connects automatically to the best local network. No hidden costs, no surprises.

Which eSIM plan fits you best?

Holidaymakers

Going away for 1-2 weeks? Pick a plan with 3-5 GB for maps, photos and messages.

Business travellers

For video conferencing and email while travelling, we suggest at least 5 GB or an unlimited plan.

Backpackers

A longer trip is better served by 10+ GB, or by a regional plan that spans multiple countries.

Families

For families with several devices we recommend a plan with tethering support and enough data.
