Indonésie : la couverture mobile

Ce que veulent dire les chiffres de Indonésie

Deux nombres comptent et un seul est celui que tout le monde cite. Le débit habituel, 38 Mbit/s, dit à quoi ressemble un bon moment.

Le dixième centile, 7 Mbit/s, c'est celui qu'il faut lire. C'est le débit du dixième le plus mauvais de la journée, quand l'antenne au-dessus de la gare est saturée et que tout le monde autour de vous est dessus. Un pays à médiane haute et à plancher bas, c'est un pays qui marche à merveille jusqu'au moment où vous en avez vraiment besoin.

Si le voyage dépend des appels vidéo ou du partage de connexion, organise toi en fonction du chiffre en heure chargée plutôt que du débit habituel.

Ce qui se passe en Indonésie quand le réseau est saturé

La congestion n'est pas une panne, c'est un mardi soir. La question est ce que votre eSIM peut y faire, et pour la plupart des eSIM de voyage la réponse est rien : un accord de gros par pays, un réseau, et aucune issue sauf acheter une deuxième eSIM chez quelqu'un d'autre, debout dans la rue.

Ici le trafic Orbislo passe par Telkomsel et XL. Quand le réseau où vous êtes se dégrade, nous vous basculons sur un autre, en plein voyage, sans que vous demandiez, et nous vous le disons après plutôt que de vous interrompre sur le moment.

Les opérateurs mobiles en Indonésie

• Telkomsel: Telkomsel, the mobile arm of the Telkom group, reported 153.5 million mobile customers at the end of June 2026, with average revenue per mobile customer of 45,600 rupiah.
• Indosat Ooredoo Hutchison: Indosat Ooredoo Hutchison reported 93.4 million mobile customers for the six months to 30 June 2026, with data traffic up 19.9 percent on a year earlier.
• XLSmart: XLSmart was formed when Smartfren Telecom and Smart Telecom merged into XL Axiata. The digital ministry approved the combined company on 17 April 2025, when it had about 95 million users.
• XLSmart: The ministry attached conditions to the XLSmart merger, including a 16 percent rise in download speeds by 2029 and digital services for more than 175,000 schools, 8,000 health facilities and 42,000 government offices.

Les anciens réseaux en Indonésie

• Telkomsel finished switching off 3G in June 2023, after converting the 3G layer on more than 49,000 base stations to 4G across all 504 cities and regencies. The programme began in March 2022, and a phone that needs 3G for data has no 3G layer to use on Telkomsel.
• 2G has not been retired on Telkomsel. At the end of June 2026 it ran about 301,000 base stations, of which roughly 246,000 were 4G, 6,000 were 5G and 49,000 were still 2G.
• When its 3G switch off finished in June 2023, Telkomsel said more than 96 percent of Indonesia's populated areas were served by its 4G network.

La 5G en Indonésie

• Telkomsel was the first operator cleared to run 5G in Indonesia, receiving its certificate of operational fitness from the ministry on 21 May 2021. Commercial 5G started on 27 May 2021 on the 2.3 GHz band, at first in a limited set of locations.
• Indosat launched its first commercial 5G service in Solo on 22 June 2021, with coverage also in Jakarta, Surabaya, Makassar and Balikpapan. Customers needed a 4G SIM registered for 5G and a data package that included 5G.
• In the July 2026 auction of the 700 MHz band, XLSmart won 2x15 MHz for 1.06 trillion rupiah, Telkomsel 2x10 MHz for 642.5 billion rupiah and Indosat 2x10 MHz for 507.48 billion rupiah.
• In the same 2026 selection for the 2.6 GHz band, Telkomsel won 80 MHz, Indosat 60 MHz and XLSmart 50 MHz of mid band spectrum.
• Winners of the 2026 700 MHz and 2.6 GHz licences must bring at least 4G mobile broadband to villages chosen from a list of 538, and provide 5G in their committed cities and regencies to reach at least 51 percent of the national population.

Le réseau en Indonésie : à savoir

• The state built Palapa Ring fibre backbone opened in October 2019. Its 12,128 kilometres link 57 regencies and cities in 11 provinces that operators found commercially unviable, completing a fibre network that reaches 514 regencies and cities.
• The eastern Palapa Ring package, the hardest to build, connects 35 service regencies and cities across East Nusa Tenggara, Maluku, Papua and West Papua. It finished later than planned because of Papua's terrain.
• On 30 April 2021 a break in the Sulawesi Maluku Papua Cable System on the Biak to Sarmi segment cut Telkom services around Jayapura. Calls and SMS came back that evening, while mobile and fixed data recovered gradually over satellite, radio links and Palapa Ring.
• In December 2025 the digital ministry counted about 2,500 villages still without internet access and set 2026 as the target year for connecting all of them.
