Staying connected during your Bali trip is easier than you might think. Whether you prefer the convenience of an eSIM or the reliability of a physical SIM card, this guide covers everything you need to know about mobile internet in Bali.
eSIM vs Physical SIM Card
An eSIM is a digital SIM that you activate on your phone without needing a physical card. It's instant — you can set it up before you even board your flight. A physical SIM card, on the other hand, gives you a local Indonesian number for calls and SMS, plus it works on any unlocked phone including older models that don't support eSIM.
Why Telkomsel?
Telkomsel is Indonesia's largest mobile operator with the widest 4G/LTE coverage across Bali. Whether you're in busy Seminyak, remote Sidemen, or on a boat to Nusa Penida, Telkomsel consistently provides the most reliable signal. This is why we exclusively offer Telkomsel packages.
How Much Data Do You Need?
For a typical tourist trip: 1-2 GB per day covers Maps navigation, social media, messaging, and light video calls. A 7-day trip would need about 8-15 GB. If you're a digital nomad working remotely with video calls and streaming, consider 20 GB or more for a 2-week stay. Our Unlimited plan is ideal for heavy users.
How to Activate Your eSIM
Activating an eSIM takes just a few minutes. After purchasing, you'll receive a QR code via WhatsApp. On iPhone, go to Settings → Cellular → Add eSIM → Use QR Code. On Android, go to Settings → Network → SIMs → Add eSIM. Scan the QR code and your eSIM will be ready. We recommend setting it up before landing so you're connected the moment you arrive.

Physical SIM Card Delivery
If you prefer a physical SIM card, we offer free delivery to your hotel or accommodation in Kuta, Denpasar, Canggu, Ubud, Sukawati, Dalung, and Tanah Lot. Just provide your address during checkout and we'll deliver it to you — ready to use. For other areas, contact us via WhatsApp and we'll work something out.
Coverage Across Bali
Telkomsel 4G coverage is excellent throughout southern Bali (Kuta, Seminyak, Canggu, Uluwatu), Ubud, and Sanur. You'll also get solid coverage in Nusa Dua, Jimbaran, and along the main roads to North Bali. Remote mountain areas and some parts of the western coast may drop to 3G, but you'll still have a usable connection.
Tips for Saving Data
Download offline maps in Google Maps before your trip. Use Wi-Fi at hotels and cafes for large downloads. Turn off auto-play videos on social media. These simple steps can help your data plan last much longer than expected.
