Best eSIM for Bali & Indonesia

For a 1–3 week Bali trip, a 10–20 GB travel eSIM installed at home is the easy win: no airport queue, no IMEI registration and no spam SMS. Airalo and Saily are the most-reported working options; a Telkomsel tourist SIM is a bit faster and better in remote spots but needs passport/KYC.

Local SIM vs travel eSIM. Telkomsel has the best coverage (Nusa Penida, Lombok, Flores) but tourist SIMs require passport registration, and phones used beyond 90 days may need IMEI registration. Some sites (e.g. Reddit) are blocked on local networks under Indonesia's 'positive internet' rules; travel eSIMs routed via Singapore usually aren't affected.

Nusa Penida and the Gilis. Signal is patchier on every provider. Download offline maps before day trips.

Quick take

Buy Airalo or Saily 10–20 GB before you fly. Staying 1–3 months or heading far east (Flores, Raja Ampat)? A Telkomsel SIM is worth the registration hassle.

FAQ

Is Airalo good in Bali?

Yes — it is one of the most-reported working eSIMs in Bali, with good speeds in Ubud, Seminyak and Canggu. Coverage is weaker on Nusa Penida for every provider.

Is a local SIM cheaper in Bali?

Yes, a Telkomsel tourist SIM is usually cheaper per GB, but needs passport registration and you buy it after landing. A travel eSIM is easier for short trips.

Do I need to register my phone's IMEI in Indonesia?

Not for a travel eSIM on a short stay. IMEI rules mainly affect phones using a local Indonesian SIM for longer than 90 days.
