Indonesia

Yes, as long as you have an eSIM-capable, carrier-unlocked iPhone. That covers the iPhone XS, XR and every model since, so anything you take to Bali or Jakarta will almost certainly work. After purchase you receive a QR code by email; scan it to add the eSIM, then keep your usual SIM active for calls and texts. Your normal number stays put on the primary line while the Indonesia travel eSIM carries mobile internet. Turn roaming off on your home line so it never picks up costly charges. The prepaid data only starts counting once you land and connect to the local network, so you can set everything up at home and arrive ready to browse, map and message.

It does. The Indonesia eSIM works on most recent eSIM-capable, carrier-unlocked Android phones, including the Samsung Galaxy S20 and newer, the Z Fold and Z Flip range, Google Pixel 3 and later, and many other current models. If your phone supports eSIM and isn't locked to a single carrier, you're good to go. Setup is the same on Android as on iPhone: scan the QR code we email you, add the eSIM as a second line, and keep your home SIM for your usual number. Switch off roaming on that home line so it stays dormant. The prepaid data activates when you first connect in Indonesia, so you can install it before you leave and have working mobile internet the moment you reach Denpasar or Soekarno-Hatta.

The Indonesia eSIM connects to Telkomsel and XL, two of the country's strongest mobile networks, with fast 5G where it's available. Telkomsel has the widest national reach, while XL is well established across the busy tourist and business hubs, so your phone automatically latches onto the best available signal as you move around. That means dependable mobile internet across Bali, Jakarta and Yogyakarta, plus solid coverage in between. You don't choose or configure a carrier manually; the eSIM manages it for you. Because it's a prepaid travel eSIM with no roaming fees, you get this network access at a flat price agreed upfront, with no surprise charges when you stream, map your route or video-call home from your hotel or villa.

Coverage is strong well beyond Bali, Jakarta and Yogyakarta. Riding on Telkomsel and XL, the Indonesia eSIM keeps you connected across popular routes and regions, from Ubud's rice terraces and the Gili Islands to Lombok, Bandung and the temples around Borobudur. Telkomsel in particular reaches deep into smaller towns and rural areas, so you'll usually hold a usable signal on road trips and day excursions. As anywhere, very remote spots, dense jungle, high mountains or some of the more isolated islands can drop to slower speeds or no service at all. For reliable tourist coverage across the places most travellers actually visit, this prepaid eSIM gives you steady mobile internet without roaming fees.

It only takes a few minutes. After you buy, we email you a QR code. On your phone, open the eSIM or mobile data settings, choose to add a new eSIM or data plan, then scan the QR code to install it. We recommend doing this on Wi-Fi before you travel. The eSIM sits alongside your normal SIM, so your usual number stays active for any calls or texts. Crucially, the validity and prepaid data don't start until you arrive in Indonesia and the eSIM connects to Telkomsel or XL for the first time, so installing early costs you nothing. When you land, enable data roaming for the eSIM line only and you'll be online. If anything looks off, our 24/7 support can walk you through it.

Yes, and we recommend it. Install the Indonesia eSIM at home on Wi-Fi as soon as your QR code arrives, so you're not hunting for an airport connection after a long flight. Installing early does not start your plan: the validity and data allowance only begin when the eSIM first connects to the local network in Indonesia, whether that's at Ngurah Rai airport in Bali or once you reach your accommodation. Until then nothing is used up. When you land, simply switch on data for the eSIM line and you're connected straight away for maps, ride-hailing apps and messaging. Setting it up in advance also means our 24/7 support can help before you fly, rather than while you're standing in an arrivals hall.

For most travellers, yes, and far more predictable. Standard roaming from a home carrier can stack up daily fees or per-megabyte charges that are easy to lose track of, especially when you're streaming, mapping and posting from Bali. An Indonesia travel eSIM works differently: you pay a flat prepaid price that's known upfront, with no roaming fees and no bill shock when you get home. You buy the data you expect to use, and if you run low you simply add another plan rather than overpaying for a big bundle from the start. It also runs on strong local networks, so you're getting genuine local mobile internet rather than a marked-up roaming connection. For a clear, capped cost on your trip, the eSIM almost always wins.

It depends on how you use your phone, but a week of typical travel use, maps, messaging, social media, browsing and the odd video call, suits a mid-sized plan comfortably. If you stream a lot of video, upload plenty of photos and reels from the beaches of Bali, or rely heavily on ride-hailing and navigation around Jakarta, lean toward a larger allowance. Light users who mostly message and check directions can get by with less. A good tip is to use hotel and cafe Wi-Fi for big downloads and back-ups, keeping your prepaid eSIM data for when you're out and about. And because top-ups are easy, you can start moderate and simply add another plan if you run low, rather than overbuying upfront.

Yes to both. The Indonesia eSIM is data-only, so it doesn't provide a local phone number or native calls and texts, but it powers all the apps you actually use to stay in touch. WhatsApp, FaceTime, iMessage and other VoIP services run over the eSIM's mobile internet, so you can call and message family and friends as normal from Bali, Jakarta or Yogyakarta. Meanwhile your usual number stays on your primary SIM in the same phone, so you still receive important calls, texts and verification codes on your home line. Just keep roaming switched off on that home line to avoid charges, and let the eSIM handle data. It's the simplest way to stay reachable on your own number while paying local prepaid rates for everything online.

Yes, personal hotspot and tethering are supported. You can share your Indonesia eSIM's mobile internet with a laptop, tablet or a travel companion's phone, which is handy when you're working from a cafe in Canggu or getting everyone online during a day trip from Jakarta. Anything you share simply draws from the same prepaid data allowance, so heavy hotspot use, video calls, big downloads or streaming to another device, will use your data faster. To keep it lasting, switch the hotspot off when you're not actively using it and lean on Wi-Fi for large transfers. There are no roaming fees on tethered data, so you pay the same flat prepaid rate whether the data is used on your phone or a connected device.

The best eSIM for Indonesia is one that runs on the strongest local networks, installs in minutes and has no roaming fees, which is exactly what the GulfData Indonesia travel eSIM offers. It connects to Telkomsel and XL with fast 5G where available, giving you dependable mobile internet across Bali, Jakarta and Yogyakarta and well beyond. You get instant QR activation by email, the freedom to install before you fly, and a flat prepaid price known upfront with easy top-ups if you need more data. It keeps your normal number active for calls and texts, supports hotspot sharing, and works on recent iPhone and Android phones. Add 24/7 customer support before and during your trip and it's a genuinely hassle-free tourist SIM alternative for Indonesia.
