Bali & Indonesia eSIM
data from $3.09.

Looking for an eSIM for Indonesia? Slashtel offers data only plans from $3.09 that connect to Telkomsel, XL, Indosat and 3, with 5G where available. No local SIM queue, no roaming shock. Buy online, install before you fly, and land in Bali or Jakarta with data ready.

Choosing an eSIM for Indonesia

The right eSIM for Indonesia gives you coverage on the main networks, enough data for your trip, a validity that matches your stay, hotspot support and easy installation before departure. Start by checking that your phone supports eSIM; most recent iPhones and many Android models do. Our guide /guides/is-my-phone-esim-compatible explains how to confirm. Next, decide how much data you need. A one week Bali holiday with maps, messaging and social media typically uses 1 to 3GB, while a month of island hopping or remote work can need 10GB or more. Validity matters: choose a plan that covers your whole trip so you are not left without data. If you plan to share your connection with a laptop or tablet, check that hotspot is included; all Slashtel Indonesia plans support hotspot. Finally, install the eSIM before you fly so you can activate it on arrival without hunting for Wi Fi. Many travellers ask us what is the best eSIM for Indonesia; we cannot answer that for you, but we can say our plans are data only, use the main networks and are priced from $3.09. That gives you a clear starting point.

Plans and prices for Indonesia

Slashtel Indonesia eSIMs come in seven data sizes and three durations, with prices from $3.09. You can pick a plan that matches your trip length and data habits. The table below shows the options and live prices. All plans are data only and include hotspot. The price you see is the price you pay; no hidden fees.

If you need a different combination, you can buy multiple plans and top up later. The 1GB plan suits a short break, while the 50GB plan is for heavy users or long stays. Prices are checked on 2026-10-29 and may change; the live price is shown at checkout.

Networks and coverage in Indonesia

Your eSIM connects to Telkomsel, XL, Indosat or 3, and the network is chosen automatically. These are the main mobile networks in Indonesia, and coverage varies by island and region. Telkomsel generally has the widest footprint, including in Bali, Jakarta, Java and many tourist areas. XL, Indosat and 3 also provide good service in cities and popular destinations. Your phone will select the strongest available network, so you do not need to manually switch. 5G is available on parts of these networks, but availability depends on your location and device. We do not claim specific speeds or coverage percentages; actual experience depends on where you are and network conditions. For island hopping, check coverage expectations for more remote islands; main islands and tourist hubs are well served. If you travel to very remote areas, download offline maps in advance.

How much data you need

Most travellers need between 1GB and 5GB for a typical holiday, but heavy users or long stays may need 10GB or more. Here are some common trip types with suggested sizes from our plans:

• One week: 1GB for 7 days, enough for maps, messaging and light browsing.
• Two weeks: 2GB for 15 days, or 3GB if you use social media often.
• One month: 3GB for 30 days as a baseline; choose 5GB or 10GB if you work remotely or stream.
• Island hopping: 5GB or 10GB for 30 days, depending on how much you share photos and use navigation.
• Heavy use: 20GB or 50GB for 30 days for digital nomads and families.

These are guidelines only. Your actual usage depends on apps, video quality and whether you use hotspot. You can monitor your data in your phone settings and top up if needed.

Install it before you fly

Install your eSIM before departure so it is ready the moment you land. Installation takes a few minutes and requires an internet connection. You can install on iPhone or Android; our step by step guide /guides/install-esim-iphone-android covers both. After installation, keep the eSIM turned off until you arrive, then enable it and turn on data roaming. The eSIM will connect automatically to a local network. Do not remove the eSIM from your phone before your trip, as you may not be able to reinstall it. If you have problems, contact support before you fly.

Calls, texts and your home number

The Indonesia eSIM is data only: no local phone number, no calls or SMS. You can still use WhatsApp, FaceTime and other apps that work over data for calls and messages. Keep your home SIM in the phone for calls and bank verification codes; you can receive SMS on your home number if your phone supports dual SIM. Make sure data roaming is turned off on your home SIM to avoid charges. The eSIM handles data, while your home SIM stays active for calls and texts.
