The short verdict
Flysimio on CelcomDigi (formerly Celcom, now merged with Digi) gives you the widest Malaysia coverage at the best price. CelcomDigi is Malaysia's largest carrier post-merger. Maxis is the main competitor with strong Peninsular Malaysia coverage. East Malaysia (Sabah and Sarawak on Borneo) has good coverage in major towns like Kota Kinabalu and Kuching, but coverage thins quickly in Borneo rainforest and around Mount Kinabalu's upper trails.

How this table is priced. Flysimio prices are read live from our carrier catalog every time this page loads, so the figure here is the figure at checkout. Competitor prices are the US-dollar price shown on each provider's own site, read on the date in the last column and linked to the page we read it from; promotional prices are marked alongside the list price. Price per GB is the plan price divided by its included data — unlimited passes have no per-GB figure and are ranked by total price instead.

Malaysia eSIM vs a local SIM card
CelcomDigi, Maxis and U Mobile sell tourist SIMs at KLIA, registered with your passport. A travel eSIM is bought online and installed before you fly, connects to CelcomDigi and Maxis when you land, and leaves your home SIM in the phone for calls and texts. The eSIM is data-only, so there is no local number. Phone settings (data roaming, keeping your number) are covered step by step in how to use an eSIM abroad.
Crossing into Singapore or Thailand? Every tier of the Asia eSIM includes Malaysia, and the 7-country tier covers Singapore, Thailand and Indonesia too.

Frequently asked questions
Can I use my US phone in Malaysia?
Yes, if it is unlocked and supports eSIM. Install the Malaysia eSIM before you fly for data, and keep your US line on for calls and texts with data roaming off, which avoids a daily carrier roaming fee.
What is the best eSIM for Malaysia?
Flysimio on CelcomDigi and Maxis was the cheapest Malaysia eSIM at 5 GB of the four providers we track when we checked in October 2026. CelcomDigi (post-merger of Celcom and Digi) has the widest national coverage including East Malaysia. Airalo and Holafly both sell unlimited-only passes for Malaysia, so the fixed-data comparison is against Nomad — see the dated index above.
Does a Malaysia eSIM cover Borneo (Sabah and Sarawak)?
Yes. Sabah and Sarawak are Malaysian states on the island of Borneo. A Malaysia eSIM covers both — you do not need a separate plan. Coverage is good in Kota Kinabalu, Kuching, and main towns. The rainforest interior has very limited signal.
Does eSIM work in Langkawi?
Yes. Langkawi island has good 4G from CelcomDigi and Maxis across the main resort areas, Pantai Cenang beach, and Langkawi town. The Langkawi Sky Bridge cable car area is also covered.
Is there eSIM coverage near Mount Kinabalu?
Yes in Kundasang town at the park headquarters. On the mountain trail above Laban Rata (3,272m), coverage is minimal. Download offline maps and the park trail map before starting your summit climb.
Can I use a Malaysia eSIM in Singapore?
No. Singapore is a separate country. A Malaysia eSIM covers Malaysia only. If crossing the Johor–Singapore Causeway, you need a separate Singapore eSIM or a regional Southeast Asia plan.
How much does a Malaysia eSIM cost?
Malaysia eSIM plans are very affordable, and ours was the cheapest 5 GB / 30-day plan of the four providers we track in October 2026 — see the dated index above. For most two-week visits with normal navigation and social media use, 5 GB is sufficient.
