The best SIM card for Bali depends on whether you need an Indonesian phone number or only mobile data. A local prepaid SIM may provide a domestic number, while a travel eSIM can be installed before departure and leaves the physical SIM slot unchanged.
Purchase location, registration requirements and network coverage matter as much as price. A large allowance does not help if the chosen network is weak around the accommodation or planned island route.
NoveSIM travel eSIMs are data-only. They support maps, Grab and internet messaging but do not include an Indonesian number, conventional calls or SMS.
Quick answer: Choose a local SIM when an Indonesian number or current domestic package is essential. Choose an eSIM when you want data prepared before arrival and a compatible unlocked phone can keep the home SIM active. Verify the network and full package terms in either case.

Best SIM card for Bali: compare the actual requirement

| Indonesian number | Eligible local prepaid SIM |

Buying a local SIM after arrival
Use an authorised seller and confirm the current identification or device-registration process. Ask what the package includes, when it expires, whether the quoted data is general-purpose and which network provides service.
Airport counters are convenient but may not offer the same packages as city shops. Travellers comparing arrival purchases should read the Denpasar Airport SIM guide before depending on a particular counter or price.
Using a travel eSIM instead
An eSIM avoids removing the physical SIM and can provide mobile data soon after landing. It requires an eSIM-compatible, carrier-unlocked device and does not meet a requirement for a local number.
Compare plan coverage with the route in Best eSIM for Bali. If the trip extends beyond Bali, use the wider Indonesia islands guide.
Check coverage beyond the resort area
- Check signal near the accommodation.
- Include Ubud, northern or eastern routes when relevant.
- Review the network around departure ports.
- Download maps before remote road journeys.
- Do not assume a Bali test predicts Lombok or Gili coverage.
The Indonesia network comparison explains why network access—not physical or embedded SIM format—determines reception.
Keep control of both SIM lines
On a dual-SIM phone, select the travel line for data and disable automatic data switching. Keep roaming off on the home SIM if it should remain available only for calls or verification texts.
Review the cost risk in Indonesia Roaming Charges. For a NoveSIM profile requiring manual APN entry, use data.esim.
If the eSIM does not connect
Check activation, the selected data line, roaming, plan validity and signal. Keep the installed profile and follow Indonesia eSIM troubleshooting; delete it only if support explicitly instructs you to.
