It is built for the common Singapore, Kuala Lumpur, Malacca and Penang route, and for anyone crossing the Johor Causeway. Coverage is excellent in Singapore and good in Malaysian cities, thinning in the Borneo rainforest and highlands. ### Singapore & Malaysia: quick facts | Fact | Singapore & Malaysia | | --- | --- | | Emergency number | 999 (police) and 995 (ambulance) in Singapore; 999 in Malaysia | | Main airports | Singapore Changi Airport (SIN); Kuala Lumpur International Airport (KUL); Penang International Airport (PEN); Langkawi International Airport (LGK); Kota Kinabalu International Airport (BKI) | | Plug types | Type G (230V in Singapore; 240V in Malaysia) | | Currency | Singapore dollar (SGD) and Malaysian ringgit (MYR) | | Apps worth having | Grab, WhatsApp, MyICA, Touch 'n Go, Google Maps | ### Crossing the Johor Causeway and the new RTS Link (Singapore & Malaysia · https://viasimo.com/destinations/singapore-malaysia/#guide-crossing-the-johor-causeway-and-the-new-rts-link) The Causeway between Woodlands in Singapore and Johor Bahru is one of the busiest land borders in the world. Many visitors cross by bus from Singapore, by car or on the KTM shuttle train, and the Second Link at Tuas is an alternative for drivers. On the crossing, your phone will switch from Singapore's Singtel or M1 to Malaysia's Maxis, CelcomDigi or U Mobile. Because both sides are covered, that happens without you needing to do anything, though it may take a minute. Near the border, your phone may switch back and forth. A new rail link will make crossing easier. The Johor Bahru–Singapore RTS Link runs 4 km from Bukit Chagar in Johor Bahru to Woodlands North in Singapore, taking about five minutes, and is planned to open in January 2027. Both stations will have customs and immigration for both countries, so you clear both checks at the departure station. At peak times, queues at the Causeway can be long. Check traffic and border queue apps before you set off, and keep your arrival card confirmations handy. ### Penang, Langkawi and the ferries to Batam and Bintan (Singapore & Malaysia · https://viasimo.com/destinations/singapore-malaysia/#guide-penang-langkawi-and-the-ferries-to-batam-and-bintan) Penang and Langkawi are popular additions to a Singapore and Kuala Lumpur trip. George Town in Penang has good coverage in the heritage area and along the beaches at Batu Ferringhi. Langkawi is well covered around Pantai Cenang, Kuah and the cable car, with weaker spots in the mangrove parks and on boat trips. The ferry between Penang and Langkawi crosses open water for part of its journey, so expect some loss of signal in the middle. From Singapore, ferries run to the Indonesian islands of Batam and Bintan, which are popular for day trips and resort weekends. Indonesia is not on this plan, so your data will stop once you leave Singapore waters and reach those islands. If you are going to Bintan or Batam, use resort wifi or buy a separate plan. Tioman Island, off Malaysia's east coast, is covered as part of Malaysia, but its jungle interior and some beaches have very limited signal. Download your ferry tickets and maps before you sail. ### Sabah and Sarawak: Kinabalu, Danum Valley and Mulu (Singapore & Malaysia · https://viasimo.com/destinations/singapore-malaysia/#guide-sabah-and-sarawak-kinabalu-danum-valley-and-mulu) Malaysian Borneo is part of this plan, and many visitors add a few days in Sabah or Sarawak. Kota Kinabalu, Sandakan and Kuching have good coverage, and so does the road to Kinabalu Park. The climb up Mount Kinabalu has coverage in some sections, but do not rely on it. Rainforest lodges in the Danum Valley, Tabin and along the Kinabatangan River are deep in the jungle, and signal there is limited or absent. Many lodges have wifi, but it can be slow and only available in shared areas. In Sarawak, Mulu National Park is reached by air, and while the park headquarters and lodges have some connectivity, the caves and trails do not. The UK Foreign Office warns of a threat of kidnapping by terrorist groups in coastal areas of eastern Sabah, including some islands popular for diving. Check the latest advice and follow the guidance of local authorities and your dive operator before travelling to that area. ### Sources for the Singapore & Malaysia guide - [SG Arrival Card (Immigration and Checkpoints Authority, Singapore)](https://www.ica.gov.sg/enter-transit-depart/entering-singapore/sg-arrival-card) - [Malaysia Digital Arrival Card (Immigration Department of Malaysia)](https://imigresen-online.imi.gov.my/mdac/main) - [Johor Bahru–Singapore Rapid Transit System (Wikipedia)](https://en.wikipedia.org/wiki/Johor_Bahru%E2%80%93Singapore_Rapid_Transit_System) - [Malaysia travel advice: safety and security (GOV.UK)](https://www.gov.uk/foreign-travel-advice/malaysia/safety-and-security) ## Eleven days from Singapore to Penang via Malacca, Kuala Lumpur and the Cameron Highlands Multi-country route · 11 days · Source: https://viasimo.com/destinations/singapore-malaysia/#itinerary An overland route up the west of the Malay peninsula, starting in Singapore, crossing the Causeway by coach to Malacca, then on to Kuala Lumpur, the tea estates of the Cameron Highlands and George Town on Penang. **When to go:** The west coast is warm all year; December to February is usually the driest stretch, while April to May and October to November bring heavier afternoon storms, and school holidays fill the Cameron Highlands at weekends. ### Day 1 in Singapore & Malaysia: Singapore: Marina Bay and Gardens by the Bay - **Base:** Singapore - **Plan:** Walk the Marina Bay waterfront from the Merlion past the Esplanade to the Helix Bridge.

If you have time before flying out of Penang International, the Tropical Spice Garden or the beaches at Batu Ferringhi are a bus ride away. - **Mobile signal:** Good on the summit of Penang Hill and at Kek Lok Si; the funicular can lose signal briefly in the tunnel section. ### Staying connected on this Singapore & Malaysia route - Fill in the Malaysia Digital Arrival Card online before crossing the Causeway, and keep your Singapore SG Arrival Card confirmation saved for the return. - Download offline maps for the Cameron Highlands before leaving Kuala Lumpur; the trails and the Mossy Forest have little or no signal. - Ferries to Batam or Bintan go to Indonesia, which is not on this plan, so switch data off if you add a day trip. ### Sources for the Singapore & Malaysia itinerary - [Visit Singapore](https://www.visitsingapore.com/) - [Tourism Malaysia](https://www.malaysia.travel/) - [UNESCO: Melaka and George Town, Historic Cities of the Straits of Malacca](https://whc.unesco.org/en/list/1223/) - [GOV.UK: Foreign travel advice, Malaysia](https://www.gov.uk/foreign-travel-advice/malaysia) - [Wikivoyage: Cameron Highlands](https://en.wikivoyage.org/wiki/Cameron_Highlands) ## About this eSIM ### Why one plan works well here Singapore and Malaysia are tightly linked. The Johor–Singapore Causeway and the Second Link are among the busiest land crossings in Asia, and many visitors combine Singapore with Kuala Lumpur, Malacca, Penang or Langkawi in one trip. With separate country plans, you would need to switch at the border. With this plan, your phone moves from a Singapore network to a Malaysian one, or the other way, and keeps working. That is particularly useful in Johor Bahru and northern Singapore. Phones on each side of the strait often pick up the other country's networks, which normally causes surprise roaming charges. Here, both sides are covered. ### Arriving at Changi or KLIA Most visitors land at Singapore Changi (SIN) or Kuala Lumpur International (KUL). Turn off airplane mode as you taxi in and the eSIM will attach to a local partner. Both countries now ask you to register before you arrive. Singapore's Immigration and Checkpoints Authority requires most travellers to submit the free SG Arrival Card within three days before arrival, through its website or the MyICA app. Malaysia's Immigration Department runs the Malaysia Digital Arrival Card (MDAC) for foreign visitors. Do these online before you fly, and keep the confirmations on your phone. At Malaysian airports, the UK Foreign Office advises that official taxis are paid with a fixed-price coupon bought at a counter in the terminal. Most visitors find it easier to book Grab, which works in both countries. ### What coverage is like Singapore is one of the best-connected places on earth, with 5G across the island and strong coverage on the MRT, including underground. Malaysia's cities, including Kuala Lumpur, Penang, Malacca, Johor Bahru, Ipoh and Kota Kinabalu, are well covered, and so are the main North–South Expressway and rail routes. Coverage thins in the highlands and the rainforest. The Cameron Highlands and Genting are mostly fine in the towns, but the jungle trails are patchy. In Borneo, Sabah's Danum Valley and Kinabatangan River lodges and Sarawak's Mulu National Park are remote, and many lodges have limited wifi. ### What you'll use data for Grab is the main ride-hailing and food delivery app in both countries. In Singapore, the MRT and buses accept contactless cards and phone wallets. In Malaysia, Touch 'n Go is widely used for transport and payments, though it usually needs a local account to top up through the app. WhatsApp is the default messaging app in both countries, used by hotels, restaurants and tour operators. Trains are a good way to link the two countries' highlights. The fast ETS trains run from KL Sentral north to Ipoh and Butterworth, the stop for the ferry to Penang, and tickets sell out at weekends and during school holidays, so book them in the KTMB app or on its website a few days ahead. If your trip stays in one country, a single-country plan does the same job; this plan pays off when your route crosses the border more than once, or includes a land crossing at Johor. ### Before you fly Submit your SG Arrival Card and MDAC online, install Grab and set up a payment card, and download offline maps for any Borneo or highland trips. Keep your home SIM in the phone for bank texts, since this eSIM is data only. ## Frequently asked questions ### Does an eSIM work in Singapore & Malaysia? Yes. Your Singapore & Malaysia eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere. ### Do I get 5G in Singapore & Malaysia? Yes, where it has been deployed. 5G runs on The local networks we use in Singapore & Malaysia, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location. ### Will my data keep working when I cross the Causeway to Johor Bahru? Yes. Both Singapore and Malaysia are on this plan, so when you cross from Woodlands to Johor Bahru your phone switches from a Singapore network to a Malaysian one and data continues. Near the border, it may switch back and forth, which is normal. If data stops, toggle airplane mode once. ### Does this plan work on a ferry trip to Batam or Bintan? No. Batam and Bintan are part of Indonesia, which is not on this plan. Your data will stop once your phone attaches to an Indonesian network. For a day trip or resort weekend there, use resort wifi or add a separate plan for Indonesia. ### Do I need to fill in an arrival card for Singapore or Malaysia? Yes, for most visitors. Singapore requires the free SG Arrival Card, submitted within three days before arrival through the ICA website or MyICA app. Malaysia asks foreign visitors to complete the Malaysia Digital Arrival Card (MDAC) online. Keep both confirmations on your phone, especially if you are crossing by land. ### Is there signal in Sabah's Danum Valley or on the Kinabatangan River? Very little. These rainforest areas are remote, and mobile coverage is limited or absent. Many lodges offer wifi, but it can be slow and only available in shared areas. Download maps, bookings and anything you want to read before leaving Lahad Datu or Sandakan. ### How much data do I need for 7 days in Singapore & Malaysia? For 7 days in Singapore & Malaysia, Viasimo sells unlimited data for $16.00. Our sizing recommendation, not a measurement: maps, messaging and the occasional lookup, about 1 GB a week; maps, social, photos and some browsing, about 3 to 7 GB a week. The data calculator on this site works it out from how you actually use your phone. ## Information and verification - **Prices and plans**: Every price and allowance on this page is read from the live catalog, not typed in.
