Does the eSIM work reliably everywhere in Bali?

In the tourist areas of Bali (Seminyak, Ubud, Sanur, Kuta and Nusa Dua) you get a stable 4G signal with Telkomsel. In remote mountain areas such as around Gunung Agung the signal can weaken, but it is usually enough for navigation and messaging.

Do I need a different SIM for each island?

No. The eSIM works on all the islands of Indonesia where Telkomsel has coverage, so on Bali, Java, Lombok, Flores, Sumatra and many more. A single plan is enough for your whole trip to Indonesia.

Do I have to register the eSIM in Indonesia?

No. Unlike SIM cards bought locally, which Indonesian authorities may require you to register, the Reisechip eSIM needs no registration on the spot. You activate it before you leave.

How much data do I need for two weeks in Bali?

For two weeks with maps, social media and occasional streaming, we recommend at least 5–10 GB. If you travel between islands a lot and book ferries or activities often, go for a 10 GB plan or an unlimited plan.

Does the eSIM also work on the Gili Islands and Komodo?

On Gili Trawangan and Komodo there is a mobile network, but it is weaker than on the main islands. It is enough for basics such as maps and messaging. For video streaming, rely on tourist Wi-Fi on site.

How much does an eSIM for Indonesia cost?

eSIM data plans for Indonesia start at €2.69. You pay once for the data you choose — no contract, no monthly fee and no surprise roaming bill. Bigger data packs and longer validity cost more.

Is an eSIM cheaper than roaming in Indonesia?

It depends on the destination. Inside the EU your German plan usually includes roaming, often with a fair-use data cap; outside the EU, roaming is typically charged per day or per megabyte, and a travel eSIM is usually much cheaper. With an eSIM you see the full price before you buy and pay only for your data pack.

Which mobile networks does the eSIM use in Indonesia?

In Indonesia the eSIM connects automatically to local networks such as Telkomsel, Indosat Ooredoo, Indosat Ooredoo Hutchison, XLSmart (XL Axiata + Smartfren), on 4G/LTE and on 5G where it is available. Coverage in populated areas is around 80% of the population. Your phone always picks the strongest network nearby.

Will I keep my German phone number with an eSIM in Indonesia?

Yes. Your German SIM and number stay active, and the travel eSIM runs alongside it as a data-only plan. You stay reachable on WhatsApp, iMessage or over Wi-Fi while browsing on the local network. Normal calls and texts still go through your German number, where roaming charges may apply.

Can I top up or extend my Indonesia data plan?

Yes. When your data runs out or the plan expires, just buy another pack. The eSIM profile already on your phone stays in place, so there is nothing to reinstall and you stay online without a break.

Can I use the eSIM as a Wi-Fi hotspot in Indonesia?

Yes. You can share the connection with a laptop, tablet or a travel companion through your phone's personal hotspot. Hotspot use comes out of the same data allowance, so choose a slightly larger pack if you plan to tether.

Should I install the eSIM before I leave or after I arrive?

Install it at home over Wi-Fi before you travel. The data plan switches on automatically when your phone joins a network in Indonesia, so you are online the moment you land instead of hunting for airport Wi-Fi.

Indonesia is an archipelago of more than 17,000 islands, from the rice terraces of Bali and the jungles of Sumatra to the Komodo dragons on Flores. If you are travelling between Ubud, Yogyakarta and the Gili Islands, you need mobile data that keeps up. Looking up temple locations, checking ferry times, booking a place to stay at the last minute: without a reliable connection that quickly becomes a chore. With a Reisechip eSIM you use the Telkomsel network, which reaches furthest across Indonesia, and you are online the moment you land in Denpasar or Jakarta, without any SIM card stress at the airport.

Why get an eSIM for Indonesia?

In Indonesia a local data plan is almost essential, and the roaming fees of German providers are especially high here outside the EU. If you want to buy a local SIM card, many counters ask for an Indonesian tax number, or you face long queues at the airport. An eSIM avoids all that: you install the profile at home, and as soon as you land in Denpasar, Jakarta or Medan your smartphone connects to the Telkomsel network automatically. With 80% coverage and 4G/LTE, Telkomsel is the most dependable partner for the major tourist islands such as Bali, Java, Lombok and Flores. On more remote islands the signal can be weaker, but in developed tourist areas you are almost always well covered. Your German number stays active for calls and WhatsApp messages home.
