Bali attracts millions of visitors annually, and mobile coverage is generally excellent in tourist areas. But head into the northern highlands or remote beach towns and the picture changes. This guide maps out coverage by region — Kuta, Ubud, Seminyak, Nusa Penida, and beyond — for 2025.
Java and Sumatra are Indonesia's two most populous islands, yet their mobile network experiences differ significantly. Java boasts dense 4G infrastructure throughout, while Sumatra presents a patchwork of urban connectivity and rural dead zones. Here's what travelers need to know in 2025.
eSIM adoption in Indonesia has accelerated but remains uneven. Local operators lag behind global eSIM platforms in tourist-friendliness. We review Airalo, Holafly, Telkomsel eSIM, and XL eSIM to identify which solutions deliver reliable connectivity without the SIM card hassle.
