Few places in Asia sell mobile data more cheaply than Malaysia. Our Malaysia plans are priced exactly like our Thailand, Singapore and Indonesia plans from one gigabyte to twenty, and the fixed sizes are where we pull furthest ahead of Airalo. In the table below, measured against their own Malaysia page on the date shown, our five-, ten- and twenty-gigabyte months cost half of theirs or less. We do not win every row, and the table shows that too. Airalo’s month of unlimited costs less than ours, and so do their three days. In Malaysia that matters less than it sounds, because unlimited is rarely the right buy here: a week of ours costs half as much again as our twenty-gigabyte month, which already holds more data than a typical week uses. Below: what the table shows, why fixed data beats unlimited in Malaysia, Borneo and the Brunei price jump, the day trips to Singapore and Thailand and when the three-country plan is the cheaper way, getting from the airport, and the networks. The final section pairs each common Malaysia trip with a plan.

Half Airalo’s price, from five to twenty gigabytes
The rows hold the amount of data level, so the validity is what changes between columns. At one gigabyte, Airalo’s plan covers three days and ours a full week, and ours is a cent cheaper. At three gigabytes, a week of theirs compares with a month of ours, which costs a little under two thirds of their price.
From five gigabytes up the gap opens. Our five- and twenty-gigabyte months each cost just under half of theirs, and our ten-gigabyte month about forty-five per cent.
The two unlimited rows are a fair fight, since each side gives a daily three gigabytes at full speed and one megabit per second after that. Our week comes in about a ninth below theirs. Their month comes in about a sixth below ours, which is the one row in the table that goes Airalo’s way.
Two sizes sit outside the table. Their three days of unlimited cost a little less than ours, and our fifty-gigabyte month costs about seven tenths of theirs.
Why fixed data beats unlimited in Malaysia
Most of what a visitor does in Malaysia, rides and food on Grab, maps, messages and photos, with hotel Wi-Fi at night, fits comfortably in a fixed month. Our week of Malaysia unlimited costs half as much again as the twenty-gigabyte month, while three days of it run a third above the ten-gigabyte month, so for ordinary use the fixed plan is both bigger than you need and cheaper.
Unlimited still has a place on a short, heavy trip: a few days of video calls for work, or a laptop running off the phone, where a fresh three gigabytes at full speed every day matters more than the price. For two weeks, a twenty-gigabyte month topped up once with ten more costs under three fifths of two weeks of unlimited.
- A week of ordinary use: the ten-gigabyte month.
- Two weeks: the twenty-gigabyte month, plus a top-up if needed.
- Two or three heavy working days: three days of unlimited.
Borneo is Malaysia, Brunei is not
Sabah and Sarawak, on Borneo, are part of Malaysia, and your Malaysia plan carries on working there. The two states do run their own immigration, so a fresh stamp goes in your passport at Kota Kinabalu or Kuching even on a flight from Kuala Lumpur, but the phone treats it as the same country.
Brunei is the exception. It sits on the coast between Sabah and Sarawak, it is a separate country with its own networks, and a Malaysia plan stops at its border. Data there also costs far more: our Brunei plans run roughly three to five and a half times the Malaysia price from three gigabytes up, and Brunei is on none of our Asia plans, only on the widest and dearest of our global plans.
The overland route shows how often it happens. The bus from Kota Kinabalu to Brunei crosses four borders and collects eight passport stamps, passing through Sabah, Sarawak and two separate parts of Brunei, and your phone moves between Malaysian and Bruneian networks along the way.
For a day or two in Bandar Seri Begawan, the one-gigabyte Brunei week, about half as much again as the Malaysia one, is enough for maps and messages. For longer, download what you need before you cross and use Wi-Fi where you can.
- Sabah or Sarawak: your Malaysia plan, unchanged.
- A day or two in Brunei: the one-gigabyte Brunei week.
- Longer in Brunei: download first and lean on Wi-Fi, because data there costs several times Malaysia’s.
A day in Singapore or Thailand: one-day plan or three-country plan
Two neighbours draw day trips. Johor Bahru faces Singapore across the causeway, and the RTS Link train, due to open around the end of 2026, will make the crossing in about five minutes. In the north, the train from Kuala Lumpur runs to the Thai border at Padang Besar in about five and a half hours, with a shuttle to Hat Yai taking just under an hour.
A Malaysia plan stops at both borders, so the day across needs cover. One way is our three-country plan for Singapore, Malaysia and Thailand, which costs about one and a half times the Malaysia plan at five gigabytes. The other is a Malaysia month with a one-day plan added for whichever neighbour you visit.
Up to five gigabytes, the three-country plan costs about the same or less than the month plus a one-day plan. From ten gigabytes up, the Malaysia month plus a one-day plan is cheaper. For several days in Singapore or Thailand rather than one, the three-country plan comes out cheaper than two country plans at every size.
Over the borders the networks change: our Singapore plans run on Singtel and M1 on 4G, and our Thailand plans on DTAC and TrueMove H.
- Malaysia with a day across, up to five gigabytes: the three-country plan.
- Malaysia with a day across, ten gigabytes or more: a Malaysia month plus a one-day plan.
- Several days in Singapore or Thailand: the three-country plan.
From the airport and along the rails
KLIA Ekspres runs from Terminal 1 to KL Sentral in 28 minutes. Since December 2025, electric ETS trains have also linked KL Sentral and JB Sentral directly, in a little over four hours on the fastest service.
Set the eSIM up before you fly and turn the line on after landing, so Grab, maps and the hotel’s directions work from the arrivals hall. The plan’s days only start once the eSIM first connects to a Malaysian network.
CelcomDigi and Maxis: the networks
Our Malaysia plans run on CelcomDigi and Maxis, both with 5G, and the phone uses whichever is stronger where you are. On our three-country plan and our Asia plans, U Mobile is added in Malaysia.
Signal is strong in the cities and along the main highways. In the highlands, on smaller islands and deep in the Borneo rainforest it thins, so download offline maps before treks and boat trips.
What your home contract charges in Malaysia
No European roaming deal reaches Malaysia. Most EU and UK contracts bill you there, often per day, and carriers in North America, the Gulf and elsewhere in Asia set their own international rates. Look up what yours charges before the flight.
For nearly everyone, then, the decision is size, and a week usually lands on ten gigabytes.
Kuala Lumpur, Penang or Borneo: a plan for each trip
Each line assumes everyday use: maps, Grab, messages and photos, with hotel Wi-Fi handling anything heavy. Add a size if a laptop or the family will share the connection.
Buy and install before you leave home, and save the one-day plans for border days.
- A stopover at KLIA: the one-day plan, two gigabytes.
- A long weekend in Kuala Lumpur: the five-gigabyte month.
- A week across KL, Penang and Melaka: the ten-gigabyte month.
- Two weeks, including Borneo: the twenty-gigabyte month.
- A heavy working trip of two or three days: three days of unlimited.
- Malaysia with a day in Singapore or Thailand, up to five gigabytes: the three-country plan.
- Malaysia with a day across, ten gigabytes or more: the Malaysia month plus a one-day plan.
- Several days split between Malaysia and Singapore or Thailand: the three-country plan.
- A day or two in Brunei: add the one-gigabyte Brunei week.
- Several people on one phone’s hotspot: go a size bigger.
Frequently asked questions
What is the best eSIM for Malaysia?
For most trips, a Malaysia month plan: five gigabytes for a long weekend, ten for a week, twenty for two weeks. Against Airalo, our five-, ten- and twenty-gigabyte months cost half of theirs or less, and in the table above six rows out of seven go our way. The row they win is a month of unlimited, which in Malaysia is rarely the right buy.
Why is fixed data better value than unlimited in Malaysia?
Because the fixed months are unusually cheap here. A week of our Malaysia unlimited costs half as much again as the twenty-gigabyte month, and that month already holds more than a typical week uses. Unlimited is worth it for two or three heavy days, or for running a laptop off the phone.
I am flying from KL to Kota Kinabalu. Do I need a new plan?
No. Sabah and Sarawak are part of Malaysia, so your Malaysia plan keeps working in Kota Kinabalu and Kuching. You will get a new passport stamp, because the two states run their own immigration, but your phone stays on the same plan.
Is Brunei covered by a Malaysia plan?
No. Brunei is a separate country with its own networks, and a Malaysia plan stops at its border. Our Brunei plans cost roughly three to five and a half times the Malaysia price from three gigabytes up, so for a day or two take the one-gigabyte Brunei week, and for longer, download what you need and use Wi-Fi.
Which plan for a day trip from Johor Bahru to Singapore?
Up to five gigabytes, our three-country plan for Singapore, Malaysia and Thailand costs about the same or less than a Malaysia month plus a Singapore one-day plan, so take it. From ten gigabytes up, the Malaysia month plus a Singapore one-day plan is cheaper. Our Singapore plans run on Singtel and M1.
When is the Singapore, Malaysia and Thailand plan the better buy?
When you spend several days in a second country: then it undercuts two separate country plans at every size. For a single day across, it is the better buy up to five gigabytes; from ten gigabytes up, a Malaysia month plus a one-day plan costs less. It covers all three countries on one eSIM, though it has no unlimited option.
Does my Malaysia plan work on the train to Hat Yai?
Only as far as the border at Padang Besar, about five and a half hours from Kuala Lumpur on the ETS. The shuttle on to Hat Yai is in Thailand, where a Malaysia plan has no data, so add a Thailand one-day plan or use the three-country plan.
Is it CelcomDigi or Maxis that my eSIM connects to?
Both. Our Malaysia plans can use CelcomDigi and Maxis, both with 5G, and the phone picks whichever is stronger where you are. On our three-country plan and our Asia plans, U Mobile is available in Malaysia as well.
What size plan suits a week in Kuala Lumpur?
Five gigabytes covers a light week of Grab, maps and messages, with photos backed up on hotel Wi-Fi. Ten is the safer size for most people, and twenty suits heavy streaming or a shared hotspot. All three cost half of Airalo’s price or less.
Will Grab still verify my account on a data-only eSIM?
Yes, as long as your home SIM stays on. Grab, like your bank, sends codes by text to your usual number, and the eSIM is data only, so keep the home line switched on for texts while the eSIM carries the data.
Is a one-day plan enough for a KLIA layover?
Yes. The two-gigabyte one-day plan, our cheapest Malaysia plan, covers a day of gate changes, messages and a Grab into the city. Staying two or three days? The three-gigabyte month is about two thirds dearer but lasts a whole month.
Can a laptop or a travel partner run off my Malaysia data?
Yes, hotspot use is included. On a month plan everyone shares the same data, so add a size. With unlimited, every connected device draws on the day’s three full-speed gigabytes, and speeds drop once those are gone until the next day.
What if my Malaysia plan runs low?
Top it up. Month plans accept extra data at any point without starting again. The one-day plan does not, so for more than a day, begin on a month plan.
Do Langkawi and Penang need a different plan?
No. Both are part of Malaysia and work on the same Malaysia plan. If you continue into Thailand, add a Thailand one-day plan for the day across.
