Will my eSIM work for the Bukit Lawang orangutan trek?

In the village, yes. But once you head into Gunung Leuser National Park the jungle canopy kills the signal, so treat the trek as fully offline and rely on your guide rather than your phone.

Does one Indonesia eSIM cover all of North Sumatra?

Yes. The single national Indonesia plan roams across the province on Telkomsel, Indosat and XL - Medan, Lake Toba, Berastagi and Bukit Lawang. Cities are well served; expect thinner coverage in the jungle and remote highlands.

Good to know in North Sumatra

The drive from Medan to Lake Toba takes four to five hours on winding roads, so load offline maps and your Parapat-to-Samosir ferry times in advance - mobile signal comes and goes across the hills.

Best time to visit North Sumatra

Drier months from May to September ease the mountain roads to Lake Toba and Berastagi and improve the odds on rainforest treks at Bukit Lawang.

Two simple ways to buy

North Sumatra eSIM plans: unlimited, or by the GB.

Every North Sumatra eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in North Sumatra — 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.

North Sumatra eSIM: your local data guide.

North Sumatra runs from the hectic city of Medan up to Lake Toba, the largest volcanic lake on Earth, and into the jungle at Bukit Lawang. You will want data to catch the Parapat ferry to Samosir Island, arrange an orangutan trek in Gunung Leuser, and navigate the winding road up to cool Berastagi. A North Sumatra eSIM keeps you connected across it all.

One eSIM for North Sumatra and all of Indonesia (Bali). It's the national Indonesia (Bali) eSIM — from $3.14/day with unlimited data, working the same in North Sumatra as it does the moment you leave it.

Across the region

Where you'll lean on data in North Sumatra.

Medan

Sumatra's biggest city has strong Telkomsel and XL 4G/5G for ride-hailing, street food and onward bus or flight bookings.

Lake Toba & Samosir

Parapat and Samosir's Tuk Tuk area have workable 4G near the lakeshore, thinning in the island's quieter Batak villages.

Bukit Lawang

The riverside village is covered, but signal drops to little or nothing once you enter Gunung Leuser's rainforest to trek.

Berastagi

This highland town holds 4G for market visits and arranging Sibayak volcano hikes, weakening on the upper trails.

The practical bit

Getting around North Sumatra on your eSIM.

Apps you'll want online in North Sumatra

Gojek— Bikes, cars, food and payments across Medan and its suburbs.
Grab— Reliable ride-hailing and airport transfers from Kualanamu into Medan.
Traveloka— Books flights, buses, hotels and Lake Toba tours in one app.
Bluebird— Metered-taxi app for dependable Medan airport runs when ride-hailing is busy.

How long to stay in North Sumatra

Plan five to seven days for North Sumatra, allowing the long drives to relax by Lake Toba on Samosir, trek at Bukit Lawang and cool off in highland Berastagi.

How much data for North Sumatra

A balanced 3-5 GB handles a North Sumatra week of maps on winding roads, ferry and trek bookings and photos; you will barely touch it while offline in the jungle.

Coverage in North Sumatra

Medan, Berastagi and the Lake Toba shoreline carry solid 4G, but coverage genuinely fades in Gunung Leuser's rainforest around Bukit Lawang, on remote Nias and in Samosir's back villages - Telkomsel reaches furthest.

North Sumatra eSIM questions, answered.

Yes, around the lake. Parapat and Samosir's Tuk Tuk tourist area have decent 4G, strongest on Telkomsel, though it weakens in the island's rural Batak villages. Download maps and ferry times before you cross the water.
