## Which Singapore, Malaysia & Thailand eSIM plan fits my route?

Your route and your data habits pick the plan, so start there.

- **Three days, Bangkok to Kuala Lumpur:** Land at Suvarnabhumi (BKK), fly on to Kuala Lumpur International (KUL), and use Grab for rides. For light use, the 1 GB for 7 days plan fits.
- **A week, Kuala Lumpur to Singapore:** Fly from Kuala Lumpur International (KUL) to Changi (SIN), using WhatsApp for messages. For standard use, choose 5 GB for 30 days.
- **Two weeks, all three countries:** From Changi (SIN), stop in Malacca, then fly from Kuala Lumpur International (KUL) to Suvarnabhumi (BKK). Heavy use, with streaming and a hotspot, suits 2 GB a day for 15 days.
- **A month, Penang to Phuket:** Fly from Penang International (PEN) to Phuket (HKT) and choose the 20 GB for 30 days plan for standard use. Use LINE to message hotels and tour operators.
- **Just one country:** A trip to one country alone suits that country's own eSIM, such as [the Thailand one](/esim/thailand).

## Which networks does the Singapore, Malaysia & Thailand eSIM work on?

Three countries, one eSIM, and all three have 5G networks. Here is who you will connect to:

- **Singapore:** your eSIM joins M1 and SingTel, and signal is strong across the whole island, including on the MRT.
- **Malaysia:** your eSIM joins CelcomDigi, Maxis and U Mobile.
- **Thailand:** your eSIM joins DTAC and TrueMove H, and LINE is the main way to message hotels and tour operators.

Your phone switches network by itself at each border, so there is nothing to change on the way. Your data reaches the internet through Hong Kong, a normal setup for travel eSIMs; [how this works](/help/ip-address-another-country).

## Using one eSIM across Singapore, Malaysia & Thailand: tips

From Marina Bay to Bangkok, one eSIM can carry you through three countries, each with its own local networks. Here's what helps most on the road.

- **Install before you fly:** Set up your eSIM at home, then keep data roaming switched on for the eSIM line at every border. The [data roaming guide](/help/turn-on-data-roaming) walks you through it.
- **Ride apps:** Grab works in all three countries, so one app can take you across all of them. Add Gojek and ComfortDelGro in Singapore, inDrive in Malaysia and Bolt in Thailand.
- **Messaging:** WhatsApp is the app to have in Singapore and Malaysia, while LINE is the main way to message locals, hotels and tour operators in Thailand. To keep your home number for calls and texts, read [keeping WhatsApp and your home number](/help/keep-whatsapp-and-home-number).
- **Top-ups:** Most plans can be topped up, so you can add more data mid-trip if you need it.
