Best eSIM for Bali 2026 — Australian guide

9 June 2026·Proost eSIM

Bali is Australia's backyard — but roaming costs aren't friendly

Bali is the most visited destination for Australians. With millions of us making the trip every year, staying connected is non-negotiable — whether you're navigating Ubud's rice terraces, organising rides through Canggu, or sharing sunsets from Uluwatu.

The problem? Telstra, Optus and Vodafone international roaming in Indonesia can cost $10–$15 per day. For a two-week Bali trip, that's up to $210 in phone bills before you've even bought a single cocktail.

What is an eSIM?

An eSIM is a digital SIM built into your phone. You buy a data plan online, receive a QR code by email, scan it, and your phone connects to a local Indonesian network. No physical SIM card, no queuing at the airport, no switching between SIMs.

Most iPhones from the iPhone XS onwards support eSIM. Most modern Android phones do too.

Bali has excellent mobile coverage in tourist areas. Seminyak, Kuta, Canggu, Ubud, Sanur and Uluwatu all have strong 4G coverage. More remote areas like Munduk or Amed will have slower speeds but still workable for maps and messaging.
