4G & 5G Coverage in Indonesia: What to Expect
eSIM from 1,00 USD · 100 MB. Networks: Telkomsel (4G), Telkomsel (5G), XL (4G).
Real-world coverage in Indonesia
4G coverage is generally good in cities and major roads. 5G is expanding — available in some capital cities and tech hubs. In practice, most travel eSIMs use 4G/LTE.
Known problem areas
- Mount Agung and Rinjani volcano trek routes
- Boat crossings between Bali and Gili Islands
- Remote jungle areas in Borneo and Sumatra
- Labuan Bajo open sea and Komodo National Park waters
Coverage by city
- Bali: Seminyak, Kuta, Ubud well-covered; rice terrace village roads can drop.
- Jakarta: Dense city; good 4G/5G; underground MRT stations improving.
- Lombok: Main towns good; Rinjani base camp and summit have no signal.
- Yogyakarta: Borobudur and Prambanan covered; rural roads between villages weaker.
- Labuan Bajo: Town has 4G; sea crossings to Komodo are largely offline.
- Gili Islands: Gili T has some signal; Gili Air and Meno very patchy.
Tip: if you're visiting rural areas or national parks, download offline maps and don't count on permanent signal.
