Indonesia eSIM guide for Gulf travellers: Bali, Puncak and Jakarta

How to stay online in Bali, Puncak and Jakarta: which networks a travel eSIM uses, where coverage is weak, how much data you need and how to set it up before you fly.

For a trip to Indonesia, a travel eSIM gives you data from the moment you land, without a local SIM shop or roaming charges from your Gulf carrier. It runs on local networks in Indonesia (Telkomsel, Indosat, XL), and your home number stays on for WhatsApp, calls and bank texts.

Coverage in Bali, Puncak and Jakarta

Bali: strong in Kuta, Seminyak and Ubud; weaker on remote beaches and on boats.

Puncak and Bandung: good in towns; gaps on tea-hill roads.

Jakarta: strong across the city.

How much data do you need?

Light use (about 0.5 GB a day): maps, WhatsApp and ride apps.

Normal use (about 1 GB a day): the above plus photos, social media and some video calls.

Heavy use (2 GB or more a day): streaming, many video calls, or sharing data with the family.

Travelling as a family? Give each phone its own plan, or buy a bigger plan for one phone and share it with a hotspot.

A tip for Indonesia

Telkomsel has the widest coverage outside cities. Check that your plan lists it if you will travel beyond Bali and Jakarta.

How to set it up

Check that your phone is unlocked and supports eSIM on our supported devices page.

Buy your plan and install it at home on Wi-Fi. It takes about two minutes.

When you land, turn on the travel eSIM, choose it for mobile data and turn on data roaming for it.

Keep your home line on for calls and texts, with its data roaming off.

Bottom line

Install the plan before you fly and turn it on when you land. See all Indonesia eSIM plans, with prices updated live.
