Indonesia
Bali and Java are well covered and cheap; the outer islands are a different story. Match the plan to how far off the main route you are going.

On the ground
Indonesia's leading operators are Telkomsel, Indosat Ooredoo Hutchison and XL Axiata.
Telkomsel has the widest reach, including smaller and remote islands where the others are absent.
Java and Bali have strong 4G and growing 5G, while outer islands vary from solid 4G to patchy or no signal.
eSIMs commonly use Telkomsel or XL Axiata, chosen for their broader reach across popular travel regions.
Popular destinations
Bali's main hubs, Kuta, Seminyak, Canggu and Ubud, all have strong, reliable 4G.
The Gili Islands and Nusa Penida are covered near the main villages and beaches, thinning inland.
Jakarta has dense urban coverage with growing 5G across the business districts.
Komodo National Park and parts of Flores can be weak or intermittent outside the main harbours.
Local or regional
An Indonesia-only eSIM is usually the smarter choice thanks to Telkomsel's uniquely wide reach.
Island hopping inside Indonesia rarely needs a regional plan, since local networks already cover the archipelago.
A regional Asia plan makes sense when Indonesia is one stop on a wider Southeast Asia trip.
Because reach varies so much between operators here, a local plan tuned to Telkomsel is the safer bet.
