5G and 4G coverage in Indonesia
5G is live in Indonesia's biggest cities and growing fast; 4G covers almost everywhere else. Here is where you get each, and how your Goodbars eSIM chooses.
The short answer
Telkomsel, the network your Goodbars eSIM runs on, has the widest reach in Indonesia. 5G is available in the major cities listed below and keeps expanding. Almost everywhere else, including most of Bali and the popular islands, runs on fast, reliable 4G/LTE. You do not choose the network: your eSIM automatically connects to the fastest one available wherever you are.

4G On 4G everywhere else
Outside the 5G cities, Telkomsel's 4G/LTE network blankets the country, including the tourist areas most travellers actually spend their time in. 4G is more than fast enough for maps, messaging, streaming and video calls. Popular spots that run on 4G include:
- Ubud (Bali)
- Seminyak (Bali)
- Uluwatu (Bali)
- Nusa Penida (Bali)
- Lombok
- Gili Islands
- Labuan Bajo (Komodo)
- Mount Bromo
- Lake Toba
- Raja Ampat
- Yogyakarta outskirts
Which network will I get?
Whichever is fastest where you are. Your eSIM connects to 5G automatically in a 5G area and drops to 4G when 5G is not available, with no setting to change. In practice you always get the best signal Telkomsel offers at your exact spot, as long as your phone supports 5G.
Coverage questions
Does Bali have 5G?
Yes, in parts. Telkomsel 5G reaches the main southern hub around Denpasar, Nusa Dua and Kuta. Popular areas like Ubud, Canggu and Uluwatu run on strong 4G, which handles maps, streaming and video calls easily.
Will my Goodbars eSIM use 5G?
Automatically, wherever 5G is available and your phone supports it. There is no setting to switch: the eSIM always connects to the fastest network at your location, 5G or 4G.
Is 4G fast enough for my trip?
For almost everything, yes. Telkomsel 4G/LTE comfortably handles maps and navigation, messaging, social media, music and video streaming, and video calls. 5G is a nice bonus in the big cities, not something you need for a great trip.
Do I need to do anything to get 5G?
No. As long as your phone supports 5G and you are in a 5G area, your Goodbars eSIM uses it automatically. You never switch networks by hand.
