Does the eSIM work in both Kuching and Miri?

Yes. It's a single national Malaysia plan, so it runs in Kuching, Sibu, Miri and across Sarawak, plus the peninsula and Sabah - one SIM for the whole country wherever you roam.

Can I rely on data for river and longhouse trips?

Not deep upriver. Coverage follows the towns along the Rejang and Baram, but fades as you head into the interior. Treat longhouse stays as largely offline and cache maps and contacts in advance.

Good to know in Sarawak

Sarawak's interior - Mulu, Bario and the upriver longhouses - has little to no mobile signal, and many are reached only by small plane or boat. Download everything in Kuching or Miri and treat connectivity upcountry as a bonus.

Best time to visit Sarawak

Sarawak is wet year-round, but the drier stretch from March to September is best for caves, jungle trekking and river trips.

Two simple ways to buy

Sarawak eSIM plans: unlimited, or by the GB.

Every Sarawak eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Sarawak — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

How much data do you need in Sarawak?

A rough, honest guide to sizing your Sarawak eSIM so you're not guessing. Most travellers in Sarawak are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Sarawak eSIM: your local data guide.

Sarawak sweeps from Kuching's colourful waterfront and the orangutans of Semenggoh to Bako National Park, the vast caves of Gunung Mulu and the longhouses up the Rejang and Baram rivers. A Sarawak eSIM keeps you booking Mulu flights and park permits, ride-hailing around Kuching and Miri, and messaging home before the signal thins upriver.

One eSIM for Sarawak and all of Malaysia. It's the national Malaysia eSIM — from $2.80/day with unlimited data, working the same in Sarawak as it does the moment you leave it.

Landing at Kuching International (KCH)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

Sarawak eSIM from $2.80/day — the whole bill, agreed before you fly.

Across the region

Where you'll lean on data in Sarawak.

Kuching

Sarawak's capital has the state's best 5G for riverfront dining, museums and Grab rides.

Bako National Park

Patchy coverage - you may get a bar near the HQ, but the proboscis-monkey trails and boat approach are largely offline.

Gunung Mulu

Signal is very limited around the caves and park, so sort permits and flights in town beforehand.

Miri

The northern oil city has dependable data, a handy base before Mulu flights or the Brunei border.

The practical bit

Getting around Sarawak on your eSIM.

Apps you'll want online in Sarawak

Grab— The main ride-hailing and delivery app in Kuching, Miri and Sibu.
Maxim— A common ride-hailing option in Sarawak, sometimes with better car availability than Grab.
Touch 'n Go eWallet— Widely accepted for cashless payments across Sarawak towns.
MASwings— Books the small-plane rural flights to Mulu, Bario and Sarawak's interior airstrips.

How long to stay in Sarawak

Give Sarawak four to seven nights - Kuching's culture and Bako in a couple of days, plus a flight to Mulu or a river-and-longhouse leg.

How much data for Sarawak

Town-based days need only a balanced 3-5 GB, but with the interior largely offline, download maps and permits ahead and reserve heavier data for Kuching and Miri.

Coverage in Sarawak

Kuching, Miri and Sibu carry solid 4G and 5G, but Sarawak's rainforest interior - Mulu, Bario and the upriver longhouses - has sparse to no mobile coverage.
