Using a SIM card or eSIM helps you:
-

Avoid depending on public WiFi
For many visitors, mobile data is a more reliable option while traveling.
Local SIM Cards in Bali
Indonesia has several mobile network operators. Coverage and speed can be different depending on the area.
Main Providers
-
Telkomsel – Widest coverage and often considered the most reliable in Bali
-
XL Axiata – Often good value and stable in popular tourist areas
-
Indosat Ooredoo Hutchison – Can be cheaper, but coverage may be less consistent in rural or remote areas
Coverage is typically strongest in South Bali (for example Denpasar, Kuta, Seminyak, and Canggu) and Ubud.
In northern Bali, mountains, and remote beaches, the signal can be weaker depending on the exact location.

Buying from official or authorized sellers helps reduce problems with registration and service quality.
What Is an eSIM?
An eSIM is a digital SIM you install by scanning a QR code. You do not need to insert a physical SIM card (your phone must support eSIM).
Common eSIM Types in Bali
-
Travel eSIMs (international providers):
Usually data-only, activated online, and made for short trips.
-
Local operator eSIMs:
Provided by Indonesian operators and may include a local phone number and other services.
Features and requirements depend on the provider and the product.
Important Information for Foreign Visitors
-
SIM Registration:
Foreign visitors using local operator SIM cards or eSIMs generally need identity verification (such as a passport). This is usually handled by official or authorized sellers.
-
IMEI Registration (Longer stays):
If a mobile device uses Indonesian cellular networks for more than 90 days, it may require IMEI registration through Indonesian Customs.
Short-term visitors usually do not need IMEI registration.
Rules and procedures can change, so long-stay visitors should check official information if needed.
Which Option Should You Choose?
-
Short trips (1–3 weeks): Travel eSIM
-
Long stays (1 month or more): Local SIM card
-
Remote work or frequent travel: Local SIM + WiFi as backup
Final Notes
Both SIM cards and eSIMs work well in Bali. The best choice depends on how long you stay, your phone compatibility, and whether you prefer convenience or better value for longer use.
With the right option, you can stay connected in Bali with more confidence and less stress.
