The easiest pick for most Indonesia trips: one app, the widest island reach, and plans you can top up mid-trip.
NordVPN's eSIM brand and the budget winner here, with ad and tracker blocking built into the app.
A global eSIM that shines on big data allowances and tethering, with a VPN bundled in - handy if you stream or work off your phone in Bali.
Long-stay pricing that gets cheaper the longer you stay, aimed at a month-plus working from Bali.
Worth it only if your trip includes a ferry, a Komodo liveaboard or a cruise. Niche, but one of the few providers with real maritime coverage.
Popular and easy if you are already booking Bali activities on Klook - one app, one login. But it is a reseller, so the underlying network and speeds are a bit of a lottery.
Four things that matter more than the marketing copy.
Most unlimited plans slow hard after a daily GB threshold buried in the fine print. In Indonesia a generous capped plan on Telkomsel often gives you more usable speed than an "unlimited" one with a 5 GB ceiling.
Telkomsel has the widest reach across Bali, Lombok, Flores and the smaller islands. A cheaper eSIM that only rides Indosat or XL can drop out the moment you leave the main tourist strips.
The airport Telkomsel tourist SIM is marked up well above local pricing, still needs IMEI registration, and lands you with an Indonesian number you probably won't use. Unless you specifically want a local number, an eSIM is the simpler call for similar money.
Bali long-stayers burn data fast. Pick for what a refill or the throttled scenario costs, not the sticker price. That's where Nomad's long-stay pricing pulls ahead.
The things that come up most for an Indonesia trip.
An eSIM is a SIM built into your phone, with no plastic card. You buy a data plan online, install it by scanning a QR code or tapping a link (do this at home on wifi), then switch it on when you land. Your home SIM stays in the phone, so you keep your normal number for calls and texts while the eSIM handles data. Works on most phones from around 2018 onward.
Most phones from the last five years do: iPhone XS and later, Pixel 3 and later, and most flagship Androids since 2020. US iPhones from the 14 onwards are eSIM-only. Check Settings > Cellular > Add eSIM before you buy. Older or carrier-locked handsets often can’t use eSIMs at all.
Rough daily guide: light use (maps, messaging, a little browsing) about 0.5-1 GB a day; normal use (social, navigation, some video) 1-2 GB; heavy use (streaming, hotspot, video calls) 3 GB or more. For a two-week Bali trip most travellers are fine on 5-10 GB, and hotel and cafe wifi stretches it further. If you work off your phone, get a bigger plan or one you can top up.
Most travel eSIMs are data-only: no local number, no regular calls or SMS. That is usually fine, since you keep your home SIM for calls and 2FA codes, and apps like WhatsApp work over data. If you specifically need a number, Saily offers a phone-number add-on in some markets, or pick up a local physical SIM. For most trips data-only is the simpler setup.
Yes, this is the best setup. Leave your home SIM in the phone for SMS codes and calls, and run the travel eSIM alongside it for data. Indonesian banks and Gojek/Grab send a lot of OTPs, so keeping your home line active matters here.
Most providers here sell regional (Asia) or global plans that cover several countries on one eSIM, which is convenient if you are hopping borders. The catch: a regional plan is often pricier per GB than buying a separate local eSIM in each country. Rule of thumb: one regional plan for short multi-country trips, individual country eSIMs if you are spending real time in each and want the best price.
Indonesia blocks foreign phones from local Indonesian SIM cards unless the handset’s IMEI is registered, and once the short tourist grace period ends that means paying import tax on the phone to keep a local SIM working. A travel eSIM sidesteps it: it connects as roaming through a partner network, which isn’t subject to IMEI registration, so you stay online without registering your phone or paying the tax. That makes an eSIM especially worth it for longer Indonesia stays.
Telkomsel has the strongest coverage outside the cities and across the islands; Indosat and XL are fine in Bali, Jakarta and Surabaya but thinner in remote areas. Most travel eSIMs don’t publish which local network they use. Airalo currently uses Indosat in Indonesia; for the others, coverage depends on whichever Indonesian network they’ve partnered with, so test it on arrival.
Yes. Telkomsel sells an eSIM, including a tourist option, and it puts you directly on Indonesia’s strongest network. The catch is setup: activation and top-ups run through the MyTelkomsel app, which is Indonesian-language and can ask for passport or ID registration. Worth it for a longer stay if you don’t mind the friction; for a short trip the travel eSIMs above are far less hassle.
Real local prepaid data is cheap, but as a visitor you buy the tourist SIM at the airport counter, which costs far more than residents pay and means handing over your passport at the desk. Against a budget eSIM like Saily the gap is small, and the eSIM skips the arrivals queue and has you online before you reach baggage claim. A physical SIM mostly earns its place on a long stay, when you want the rock-bottom local rates and a local number and don’t mind topping up through the Indonesian-language MyTelkomsel app.
There are hundreds of travel eSIMs out there. We deliberately stick to the big, proven names (Airalo is the world's largest) rather than no-name resellers that might be a few cents cheaper but come with clunky installs, thin support, or security question marks. From there we compared each provider's published Indonesia coverage, local network partner, current pricing, fair-use and hotspot policies, App Store and Google Play ratings, and traveller reports from Reddit and Bali digital-nomad communities. The signal rating is our own honest read, and providers differ on purpose. Prices shift often, so confirm the live figure on the provider's site for your dates.
