Best eSIM for Malaysia: My Test Results (10+ Providers Compared)

If you're travelling to Malaysia, using your home provider for data can be shockingly expensive, often costing £6 per day or more. To avoid these high charges, a travel eSIM is the smart choice. With prices starting from under £0.50, staying connected is both affordable and hassle-free.

In this article I compare the best options based on real data. This isn't just a list: I recently spent a few days in Kuala Lumpur and used that time to personally speed-test 10 of the most popular providers, including Airalo, Holafly, Ubigi and Jetpac. I found huge differences in speed and stability, so picking the right one actually matters.

Short on time? Use code FYESIM10 for a 10% discount with Ubigi. It offered the best value for money and overall performance in Malaysia, with the most stable connection and a local IP address.

Malaysia eSIM for UK Travellers

Why not just roam with your provider from home? While easy, roaming with your British SIM is incredibly expensive. Most UK providers (like O2, Vodafone and EE) charge flat-rate "Rest of World" passes that often cost around £6 per day.

On top of the high price, performance can be disappointing. As I saw in my previous tests in Bali, roaming traffic is often routed all the way back to the UK. This results in high latency (lag), making tasks like video calls or loading maps feel sluggish.

You have two much better choices: a local SIM card (which you can pre-order for airport collection) or a travel eSIM. In most cases, a travel eSIM is the superior choice. It offers a fast, local connection from the moment you land, without the hassle of airport queues or passport registration, with plans starting from just £0.50.

How to Choose the Right eSIM for Malaysia?

Which eSIM is best depends on how you plan to travel in Malaysia. The most important factor is which network your eSIM connects to. If you're staying in Kuala Lumpur, Penang or other cities, most plans will serve you perfectly well and you might just go for the cheapest option. If your trip takes you inland, or to Langkawi or Borneo, you'll want a provider on a premium network like Maxis or CelcomDigi.

I tested 10+ providers and four clearly stood out:

• Ubigi for the best overall experience, with a local IP address and the best latency in my test
• Airalo for the fastest speeds, clocking over 300 Mbps in Kuala Lumpur
• Jetpac for great performance and travel perks, with free lounge access on delayed flights
• iRoamly for the best value, with fast data at low prices

How much data do you actually need? It pays to think about this beforehand. Use our data calculator to estimate what you'll really use on your trip. Want to compare prices? Browse all 40+ providers via our Malaysia eSIM comparison tool. Or read on for my personal review.

Unlimited data eSIM for Malaysia

Are there "unlimited" eSIMs for Malaysia? Yes. However, be aware that truly unlimited high-speed data, as you might know it from home, doesn't really exist for travellers in Malaysia yet. Unlike destinations such as Thailand or Japan, where local tourist offers can be more generous, "unlimited" plans in Malaysia are primarily a convenience product. They are almost always subject to a daily high-speed limit.

When choosing an unlimited eSIM, it's wise to check this very carefully. I'd advise avoiding providers that don't clearly state this limit or, worse, hide behind vague terms about the "local network".

• Transparent options: For example, Superalink and Truely are good choices that offer a generous 5 GB per day.
• Speed warning: Be aware that some "unlimited" eSIMs can suffer from very low base speeds from the start, as I personally experienced with Holafly during my tests.

All Test Results

Overall, most providers performed well. However, be aware that several providers route data via Hong Kong. This means apps like ChatGPT and TikTok are blocked unless you use a VPN (worth noting: Saily includes a built-in option to bypass this).

Airalo was the fastest provider, while Ubigi offered the most stable connection and a local IP address. Just as in Indonesia and Singapore, Holafly was by far the slowest eSIM: its speed was barely one-tenth of Airalo's.

All eSIMs were tested at the same location and under the same conditions in the heart of Kuala Lumpur, using the Ookla app on an iPhone 16 Pro. These tests were conducted in July 2025. Results are a snapshot in time, and providers can change their network partners at any moment. Note that this time I only tested in Kuala Lumpur: if you venture inland, or head to Langkawi or Borneo, you likely won't see the exact same results.

Local networks in Malaysia

These are the major mobile networks in Malaysia:

• Celcom & Digi (recently merged as CelcomDigi)
• Maxis
• U Mobile
• Unifi
• Yes

According to the November 2024 Mobile Experience Report by Opensignal, the landscape is highly competitive. Celcom and Digi are the clear winners for download speed and coverage, while Maxis takes the crown for consistent quality.

While 5G is widely available in tourist centres like Kuala Lumpur and Penang, high-speed 4G/LTE remains the reliable backbone across the rest of the country. Your experience will depend heavily on the network your eSIM partners with. Generally, Maxis and CelcomDigi are considered the premium providers with the most extensive coverage, especially if you venture inland or to Borneo (Sabah and Sarawak). Many top eSIMs, such as Ubigi and Airalo, partner with one of these primary networks to ensure the best connection.

Buying a local SIM card

Prefer a local SIM card or eSIM? You can buy one on arrival at the airport or pre-order online. Personally, I strongly prefer a travel eSIM for the sheer convenience. Buying a local SIM means queuing up and presenting your passport for mandatory registration, which is often the last thing you want to do after a long, tiring flight.

However, if you're staying in Malaysia for a longer period or need massive amounts of data (more than 50 GB), a local option is worth considering.

Important: if you pre-order, pay close attention to your arrival terminal. Kuala Lumpur International Airport is split into two distinct terminals: KLIA1 (for most major international airlines) and KLIA2 (mainly for budget carriers like AirAsia). They are separate, so make sure you select the correct terminal for collection.

Check the fine print. Some local "unlimited" options look attractive but come with severe speed caps. As seen above, the "unlimited" data is capped at a mere 3 Mbps, which feels incredibly slow compared to the 300+ Mbps speeds I tested with Airalo.
