Stepping off the plane in Bali or Jakarta and hunting for a SIM kiosk is the last thing you want after a long flight. With a HelloSIM eSIM, you arrive already connected, ready to book a Grab, message your hotel, or pull up Google Maps the moment you switch on your phone.
Why use an eSIM in Indonesia
Indonesia is huge, spanning thousands of islands, and staying online keeps everything smooth, from ride-hailing apps to digital payments. An eSIM skips the queues and the language barrier at the airport.
- No physical SIM to swap or lose
- Install before you fly and activate on landing
- No surprise roaming charges from your home carrier
- Keep your home number active for calls and texts
Networks & coverage
HelloSIM connects to Indonesia's strongest networks, including Telkomsel, Indosat, and XL Axiata. You get fast 4G/LTE almost everywhere, with growing 5G in major hubs.
- Jakarta has dense 4G and expanding 5G coverage
- Bali (Denpasar, Ubud, Seminyak) offers reliable 4G across tourist areas
- Surabaya and other big cities are well covered
Remote islands and inland highlands can be patchier, so download offline maps for trips like Komodo or remote Sumatra.

- Regular use (social, browsing, some video): 5-10 GB for a week or two
- Heavy use (streaming, hotspot, remote work): 15-20 GB or an unlimited plan

FAQ
Is my phone compatible with an eSIM? Most recent iPhones (XS and newer), Google Pixels, and flagship Samsung Galaxy models support eSIM. Check your settings for an "Add eSIM" option, and make sure your phone is carrier-unlocked.
When should I install the eSIM? Install it before you travel using your home Wi-Fi, then simply activate the data line when you arrive in Indonesia. Installation does not start your plan.
Can I keep my WhatsApp number? Yes. WhatsApp is tied to your existing phone number, not the eSIM data line, so it keeps working normally while you use the eSIM for data.
