## Which Asia eSIM plan fits your route through these seven countries?

Start with how many days you'll be away and how much data you'll use, then match your route to one of these.

- **A three-day hop from Singapore to Kuala Lumpur, standard use:** pick 500 MB a day for 5 days, as standard use over three days comes to about 2.1 GB.
- **A week from Hanoi to Siem Reap, standard use:** pick 5 GB for 30 days, as standard use over a week comes to about 4.9 GB.
- **Two weeks from Bangkok to Kuala Lumpur, heavy use:** pick 2 GB a day for 15 days, as heavy use over two weeks comes to about 25.2 GB.
- **Only Thailand:** if Thailand is your one stop, [the Thailand eSIM](/esim/thailand) is the one to buy for that trip.

Unlike Asia (12 countries), this bundle covers the Philippines, so pick it if that is on your route.

## Which countries and networks does the Asia eSIM cover?

Bangkok, Hanoi and Bali, all on one eSIM. It covers seven countries, and six of them have 5G networks. Here are the networks in the four countries travellers visit most:

- **Thailand:** DTAC and TrueMove H
- **Vietnam:** MobiFone, Vietnamobile and Viettel Mobile
- **Indonesia:** Telkomsel
- **Malaysia:** CelcomDigi, Maxis and U Mobile

Your phone switches to the local network by itself at each border, so there's nothing to change as you go. Your data reaches the internet through Hong Kong, a normal setup for travel eSIMs. You can read more about [IP addresses in other countries](/help/ip-address-another-country).

## Using one eSIM across Asia: tips for crossing borders

- **Bangkok, Siem Reap, Hoi An:** one eSIM spans all seven countries, so you keep the same plan as you move between them. Install it at home before you fly.
- **Data roaming:** keep it on for the eSIM line at every border, so your phone can join each new network. [Turn on data roaming](/help/turn-on-data-roaming)
- **Rides and messages:** Grab works for rides in Thailand, Indonesia, Vietnam, Cambodia and Malaysia, plus Bolt in Thailand and Gojek in Indonesia. Use LINE in Thailand, WhatsApp in Indonesia and Malaysia, and Zalo in Vietnam, where Telegram is blocked.
- **Home number:** keep your home number for calls and texts, and sort out WhatsApp before you go. [Keep WhatsApp and your home number](/help/keep-whatsapp-and-home-number)
- **Topping up:** most plans can be topped up mid-trip, so you can add more data along the way without buying a new eSIM.

## Questions

### How much is an eSIM for Asia?

Asia eSIMs start at £3.99 for 500 MB a day over 1 day. A 5 GB plan for 30 days costs £14.99. Prices include any taxes and show in pounds, euros or dollars.

### Which countries does the Asia eSIM cover?

One eSIM works in all 7 countries: Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand and Vietnam. The full list with the network in each country is on this page.

### When does my Asia eSIM start?

Most plans start the moment your eSIM first connects to a network in Asia, so you can buy and install it at home before you fly. Install it within 180 days of buying.

### Can I top up my Asia eSIM?

Yes. Most Asia plans can be topped up from your eSIM page in two taps, with no new QR code. The plan table on this page shows which ones.

### Does it come with a phone number?

Every eSIMology plan is data only. Keep your own SIM switched on for calls and texts, and use WhatsApp, FaceTime or any calling app over your eSIM's data.

### What if my plans change?

Cancel an eSIM you haven't installed within 30 days for a full refund to your card, in two taps from your eSIM page.

### Does the Asia eSIM work in Cambodia?

Yes. Cambodia is one of the seven countries here, and it's the one that sets this bundle apart from Asia (19 countries), which doesn't include it. Your eSIM connects to Metfone, the network for Cambodia.

### Can I use one Asia eSIM for Thailand and Vietnam?

Yes. Thailand and Vietnam are both on this bundle, so one eSIM can carry you from Bangkok to Hanoi. In Thailand it connects to DTAC or TrueMove H, and in Vietnam to MobiFone, Vietnamobile or Viettel Mobile.

### Does the Asia eSIM include Japan?

No. Japan isn't one of the seven countries on this bundle. The Asia eSIM with 20 countries covers Japan, and it also includes all seven countries here. If Japan is on your route, that's the one to pick.

### Can I use Telegram in Vietnam on the Asia eSIM?

No. Telegram is blocked in Vietnam, so you won't be able to use it there. Zalo and Messenger are the messaging apps to use instead. Get them ready before you land.

### Which ride apps can I use in Indonesia?

Grab, Gojek and inDrive are the ride apps for Indonesia, so they're handy in Bali, Jakarta and Yogyakarta. Your eSIM connects to Telkomsel there, the one network in Indonesia on this bundle.

### Is there 5G on the Asia eSIM?

Yes, in six of the seven countries on this bundle, so it's worth checking the country details for each stop on your route before you fly.
