Bali Mobile Coverage Guide
Bali has good mobile coverage in most tourist areas. Telkomsel offers the strongest island‑wide signal, while XL Axiata performs well in the south and central regions. This guide explains what to expect in each part of the island so you can choose the right SIM or eSIM for your trip.

🌴 South Bali (Canggu, Seminyak, Kuta, Legian)
Coverage is excellent across all major providers. Telkomsel and XL both perform well, with fast data speeds and stable connections.
🌿 Ubud
Central Ubud has strong coverage from all providers. Speeds may drop slightly in rural outskirts, where Telkomsel remains the most reliable.
⛰️ Uluwatu & Bukit Peninsula
Coverage is generally good, but cliffside areas can be patchy. Telkomsel performs best here, especially near beaches and surf spots.
🌊 Sanur & Denpasar
Strong, stable coverage from all networks. Ideal for remote workers and long‑stay travellers.
🌄 North Bali (Munduk, Lovina, Amed)
Coverage becomes less consistent. Telkomsel is the only provider with reliable reach in most northern areas. XL may drop to 3G or lose signal entirely.
🏝️ Nusa Penida, Lembongan & Ceningan
Coverage varies by location. Telkomsel is the most reliable, especially in hilly or remote parts of Nusa Penida. XL and eSIMs work well in main villages.
