You step off the plane at Jakarta Soekarno-Hatta (CGK) or Bali Ngurah Rai (DPS). The air is warm and the terminal is busy. You need a ride, a map, and a message to your family. A local SIM queue is not what you want after a long flight. With a Slashtel eSIM, you land connected.
Buy your Indonesia eSIM before you leave home. Your QR code arrives by email within a minute. Install it on your phone, and when you land, it connects automatically. You pay from $3.09, with no contract and no local address needed. It is data only, so no local number, calls, or SMS. But WhatsApp calls work over data, and you can top up online on the same eSIM if you need more. Days start counting only when it first connects in Indonesia.
UK travellers head to Indonesia for Bali holidays, backpacking and island hopping. They fly into Jakarta or Bali, then move between islands. They need data for booking hostels, finding warungs, and sharing photos. A reliable eSIM means they can navigate without hunting for Wi-Fi.
Indian travellers often choose Bali for holidays and honeymoons. They want to stay connected with family, share updates, and use ride-hailing apps. An eSIM keeps their Indian SIM active for OTPs while giving them local data. It is simple and works as soon as they land.
| Data | Duration | What it covers |
|---|---|---|
| 1GB | 3-5 days | Maps, WhatsApp text, light email. No video. |
| 3GB | 1 week | Maps, WhatsApp calls, occasional social media. |
| 5GB | 2 weeks | Maps, WhatsApp video, some music streaming. |
| 10GB | 1 month | Daily use including video and video calls. |
For a 1-2 week trip, 3GB to 5GB is a good starting point. If you plan to stream music or video, or work remotely, go for 10GB. You can always top up online if you run out.
Ride-hailing apps like Grab and Gojek need mobile data to book and track rides. These apps are essential in cities like Jakarta and Bali. Without data, you cannot book a car or bike. Make sure your eSIM is active before you try to get a ride from the airport.
Coverage is good in towns and tourist areas but can drop on small islands and during boat crossings. In Bali, Jakarta, and Lombok, you will have signal in most places. On the Gili Islands, coverage exists but can be slower. During boat trips between islands, expect no signal for a while. Download offline maps as a backup.
