The 100 million refers to how many sim cards, the word subscribers is misleading. A couple of years ago only 46% of Indonesians owed a smartphone and 6% stream of that. If one based their figures around this it would give a more realistic view on numbers as absolute minimum. One can assume numbers have increased since then, perhaps 10-15% could be the case, I'll leave that to holder's to source. 500k subs in one year is a big ask IMO based on known figures.
