I want to use 4G as much as possible when traveling in Indonesia.
Does anyone know (has experience?) which mobile network provides the best 4G coverage in Indonesia?
Some online articles have done the research for you:
For coverage, Bolt takes the lead by covering 750,000 users in Jakarta, Bogor, Depok, Tangerang, and Bekasi areas. Telkomsel, the country’s biggest operator, covers a few areas in Jakarta and Bali. While XL Axiata mostly provides 4G speed in Bogor, Medan, and Yogyakarta. XL is still holding 4G trials in Jakarta, mostly covering only Kelapa Gading area in North Jakarta. Indosat’s coverage is quite small: a few areas surrounding Jakarta’s Monas, Thamrin, and Sudirman districts.
"I want 4G while traveling in Indonesia" !!!!???!!!
Unless you want to travel only in the center of big Javanese city, your request is as absurd as asking for only the best cheese on the Moon.
Indonesia is a Huge country and Indonesia is a POOR country. Not poor like Detroit city, mind you. Poor like "my son died because there was no running water at the hospital"
So, if you want 4G, OK... read Mayo's link. If you want to travel, accept that Edge is often the best you will get. And you won't always get it.
And the widest coverage is clearly Telkomcel. Unfortunately, it is also the slowest and more expensive).
As an illustration, I live in North Sumatra and everybody agree that Bold is the best 4G operator. But it work ONLY in Medan. It provides no network AT ALL in any other place (probably soon in Banda Aceh)
