Good to Know

If you're heading straight to the Gilis, buy your SIM and get it activated before boarding the boat from Bangsal or Senggigi. Dealing with registration once you're on Gili Trawangan or Gili Air is a hassle you don't need. Sort it on the mainland.
On cost, a local SIM wins clearly. Indonesian data is among the cheapest in Southeast Asia, and a tourist plan from Telkomsel or Indosat undercuts e-SIM pricing for anything beyond a few gigabytes.
Avoid logging into banks on hotel WiFi if you can use mobile data instead. Keep your phone's OS updated. Turn off auto-connect to open networks so you're not silently joining a lookalike hotspot.
Mobile signal is available in Senaru and Sembalun (the two main Rinjani trailheads), but once you're on the trail above roughly 2,000 metres, connectivity largely disappears. Telkomsel gives you the best chance of a fleeting signal at the crater rim (3,726m) on a clear day, but it's not something to rely on.

e-SIM

Availability: For e-SIM internet in Lombok, available: Telkomsel e-SIM, Smartfren, Indosat Ooredoo and XL Axiata.
Use Case Recommendation: An e-SIM makes a lot of sense for Lombok if your phone supports it and you're staying two weeks or less. You activate it before you land. The moment you switch off airplane mode, you're online, and you skip the registration desk entirely.
Registration Requirements: Indonesia requires passport registration for all SIM cards, a regulation tightened in 2018, and the kiosk handles the paperwork for you, usually 5 to 15 minutes.

Recommended Providers

Airalo
Note
The most widely used option for Indonesia and tends to be straightforward to set up.
Price Note
e-SIM data for Indonesia typically costs noticeably more per gigabyte than a local Telkomsel or Indosat plan bought at a kiosk.
Holafly
Note
Offers unlimited data plans for longer stays.

Mobile And SIM

Network Technology: 5G is technically available in pockets of Mataram. Don't plan around it. 4G is what you'll use.
Gili Islands Coverage: Coverage on the Gili Islands is generally good for messaging and maps, though speeds dip when boats of tourists arrive and everyone hits the network at once.

Primary Carriers

Telkomsel
Speeds
Speeds in Mataram and Senggigi tend to run 20 to 40 Mbps on 4G, which handles video calls and streaming fine.
Coverage
Most locals and long-term expats recommend Telkomsel, for good reason. Its coverage extends furthest into the rural east and up around Sembalun and the Rinjani trekking villages.
Indosat Ooredoo (IM3)
Coverage
Usually a bit cheaper. It works well across the tourist belt from Kuta Lombok up to Senggigi and on the Gilis, though it can thin out in the interior.
XL Axiata
Coverage
Sits somewhere in between on price and coverage. It's a reasonable second choice if Telkomsel shops are out of stock.

Prepaid SIM Pricing

Cost Estimate: IDR 75,000
Typical Package: 50,000–100,000 IDR with 10–30 GB (30-day validity)

Connectivity Reliability Tier

moderate

Connectivity Reliability Tier Rationale

Fiber optic links now reach major areas including Mataram, Senggigi, and Kuta Lombok, with Telkomsel offering the broadest 4G coverage across the island, with download speeds typically ranging from 5–20 Mbps in towns, but coverage remains uneven in rural areas and reliability varies outside main tourist hubs.

Home Broadband

Advertised Speeds: Speeds ranging from 75 Mbps to 500 Mbps depending on your location, with fiber connections routinely clocking up to 100 Mbps.
Typical Monthly Cost: IDR 250,000
Availability And Providers: Fiber optic links now reach major areas including Mataram, Senggigi, and Kuta Lombok. Mataram and Senggigi have acceptable fiber coverage, but rural areas like Kuta Lombok or Sekotong may only have limited access to fixed-line internet.
Reliability Notes: Outages do happen, and bandwidth can be inconsistent during peak hours. Many expat property owners opt for dual-provider setups, using two different ISPs to ensure backup connectivity. Others install signal boosters to improve coverage or invest in satellite internet systems for guaranteed access.

Wi-Fi

Quality Considerations: Budget guesthouses often have weak signals in rooms — sitting near the router helps.
Hotel And Cafe Availability: WiFi is widely available at hotels, cafés, and restaurants in tourist areas like Senggigi, Kuta Lombok, and across the Gili Islands, though speeds and reliability vary considerably.
Recommendation For Remote Work: For anything bandwidth-demanding — video calls, remote work, uploading content — a local SIM card with a data plan is a far more dependable option than relying solely on venue WiFi.
