Malaysia is two places in one: the peninsula, with Kuala Lumpur, Penang, Melaka and islands such as Langkawi and the Perhentians, and Malaysian Borneo across the South China Sea, with the rainforests and mountains of Sabah and Sarawak. Ride-hailing, maps and messaging run most trips here, and coverage is good in the cities and along the main roads. Malaysia is not part of the EU's Roam Like at Home area, and European plans usually charge roaming by the day.
This guide covers the apps that do the work, the places where the signal fades, and the numbers to save.
Key facts for Malaysia
- EU roaming: not covered by Roam Like at Home
- Local networks: U Mobile, CelcomDigi, Maxis (depending on the plan)
- Emergency numbers: 999 for police, ambulance and fire; 112 from a mobile phone
- Embassies: in Kuala Lumpur, with consulates in Penang, Kuching and Kota Kinabalu for some countries
Eastern Sabah
The UK advises against all but essential travel to all islands and dive sites off the coast of eastern Sabah, from Sandakan to Tawau, because of the threat of kidnapping. That stretch includes Lankayan and the dive islands off Semporna, such as Sipadan and Mabul. The Sabah mainland, including Kota Kinabalu and Mount Kinabalu, is not covered by this advice.
Kuala Lumpur: Grab, trains and Touch 'n Go
Grab is the main ride-hailing app in Malaysia, for cars as well as food delivery, and it shows the fare before you book. The KLIA Ekspres train links the airport with KL Sentral, and the LRT, MRT and monorail cover the city. A Touch 'n Go card pays for public transport and motorway tolls, and you can top it up at convenience stores.
Paying: cards, QR wallets and ringgit
Malls, hotels and most restaurants accept cards. At hawker centres and night markets, cash in ringgit is still the safest option, because many stalls take only cash or a local QR wallet.
The islands
Penang and Langkawi are well covered, main beaches included. On smaller islands such as the Perhentians, Tioman or Redang, the signal is good near the villages and jetties and patchy on the far beaches and at dive sites. On the east coast, boats and many resorts reduce or stop service during the monsoon, from about November to February.
Borneo: Sabah and Sarawak
Kota Kinabalu and Kuching are well covered, but in the rainforest, on river trips and on the trails of Mount Kinabalu the signal becomes sparse or disappears. Download maps and your bookings before heading inland. Sabah and Sarawak run their own immigration checks, so keep your passport with you even on domestic flights from Kuala Lumpur.
Crossing to Singapore
Johor Bahru sits across the causeway from Singapore, and near the border your phone can pick up Singaporean networks. A plan for Malaysia alone does not work in Singapore; if your trip includes both, choose an Asia plan that covers the two countries.
Getting connected
A travel eSIM is installed at home with a QR code, and its validity starts with the first connection in Malaysia. Your usual number keeps receiving texts and bank codes, while Grab, maps and messaging use the eSIM's data.
Malaysian prepaid SIMs are sold at the airport and in convenience stores, and they are registered with your passport.
Consular protection: who to call in Malaysia
- 999 reaches the police, an ambulance or the fire service; from a mobile, 112 also connects you, and 994 goes straight to the fire and rescue service.
- Embassies are in Kuala Lumpur, and some countries also have consulates in Penang, Kuching or Kota Kinabalu. The Telcomia app shows yours, with address and phone.
- If you are an EU citizen and your country has no embassy or consulate in Malaysia, the embassy of any other EU country must help you on the same terms as its own nationals (Article 23 of the Treaty on the Functioning of the EU).
- Emergency phrases in Malay are ready to show on screen in the app.
Questions travellers ask about Malaysia
Which app should I use for taxis?
Grab, which covers cars and food delivery and shows the fare before you book.
Does my phone work on the islands and in Borneo?
In towns, resorts and on the main roads, yes. On remote beaches, river trips and mountain trails the signal can disappear.
Which networks does a Telcomia eSIM use in Malaysia?
U Mobile on most plans, and CelcomDigi or Maxis on some, with 4G and 5G where available.
Does a Malaysia plan work in Singapore?
No. For a trip to both, choose an Asia plan that covers the two countries.
The short version
Install the eSIM and Grab before you fly, carry some ringgit for hawker stalls, keep your passport handy in Sabah and Sarawak, and save 999.
