Is 10GB enough for a week in Bali?

For most holidaymakers, yes, and often for two weeks. If you use villa, hotel and cafe Wi-Fi for streaming and big downloads, 10GB comfortably covers maps, ride-hailing, messaging and everyday scrolling while you are out. Heavy daily video calls or streaming on mobile data are what push people up to 20GB.

Is 20GB enough for a month in Bali?

For a normal month it usually is, especially if you rely on Wi-Fi where you sleep. Remote workers with daily video calls should watch their usage in the first week: if it is climbing fast, a top-up or the 50GB plan gives you room without the stress of running dry.

How much data does Google Maps use in Bali?

Very little, roughly 5 to 20 MB an hour, and ride-hailing in Gojek and Grab is just as light. You could navigate all week and barely notice it. Streaming video and social autoplay use far more.

Does WhatsApp video calling use a lot of data?

More than you might expect: a video call runs roughly 200 to 700 MB an hour, against almost nothing for texts and voice notes. A daily call home is often what tips a working traveller from the 10GB plan to 20GB.

Can I just use hotel and cafe Wi-Fi in Bali instead of mobile data?

For a lot of your usage, yes, and it stretches any plan further. But Bali Wi-Fi is patchy and slows at peak times, and you still want data for maps, ride-hailing and messaging the moment you leave the building. Most people treat the eSIM as the reliable layer and Wi-Fi as the bonus.

What happens if I run out of data mid-trip?

You buy a top-up rather than starting over, so running low is a minor thing, not a trip-ender. That is why it is safe to choose the smaller plan when unsure: check your usage in your phone settings after a couple of days and top up only if you actually need it.

How much data do you need in Bali?

The short answer

For a typical Bali holiday, 10GB comfortably covers one to two weeks. If you work remotely, stream, or stay longer, 20GB is the safer pick, and 50GB is for hotspotting a laptop or sharing across a trip. The answer is a range rather than a single number because of Wi-Fi: almost every villa, hotel, cafe and coworking space in Bali has it, so your eSIM mostly fills the gaps when you are out on the scooter, at the beach, or stuck in traffic. The more you lean on Wi-Fi where you sleep, the further any plan stretches.

What actually uses your data

Most people overestimate the light stuff and underestimate the heavy stuff. Rough hourly figures, which shift with quality settings and signal:

Maps and navigation: about 5 to 20 MB an hour. A whole week of Google Maps barely dents a plan, and ride-hailing in Gojek and Grab is just as light.
Messaging and voice calls: under 30 MB an hour. WhatsApp texts, voice notes and voice calls cost almost nothing in data terms.
Social scrolling: roughly 500 MB to 1 GB an hour. Instagram and TikTok are the quiet budget-eaters, because autoplay video in feeds, Stories and Reels adds up fast.
Video calls: about 200 to 700 MB an hour. A daily call home or a work stand-up is the line that pushes remote workers from 10GB toward 20GB.
Streaming video: 1 to 3 GB an hour. Netflix or YouTube in HD is by far the heaviest thing you can do on a phone, and it is what fills a 50GB plan.

A realistic day in Bali

Picture an ordinary day: maps to breakfast, ride-hailing across town a few times, an hour of scrolling by the pool, a short video call home, and messaging throughout. Off Wi-Fi, that comes to roughly 1 to 1.5 GB. Swap the villa Wi-Fi for mobile data on a couple of evening episodes and you can double it. So a light-to-moderate week tends to land around 5 to 8 GB, and a heavier or longer trip climbs from there, which is exactly why the plans step up in the sizes they do.

What nudges Bali travellers up or down

A few things specific to Bali tip the balance. Cafe and coworking Wi-Fi is everywhere in Canggu, Ubud and Seminyak, but it slows to a crawl at busy times, so working travellers end up on mobile data more than they expect. Maps and ride-hailing run almost constantly, because the back lanes are hard to navigate and cars are best booked in the app rather than flagged down. And if you are here to work, daily video calls alone can decide your plan. At the other end, a villa-and-beach holiday with strong Wi-Fi where you sleep can make even a 10GB plan last a comfortable fortnight.

Matching it to a plan

The three plans map onto this simply. 10GB (€13.99) suits a normal one to two week holiday. 20GB (€19.99) is the comfortable choice for remote work, heavier social and streaming, or a longer stay. 50GB (€39.99) is for hotspotting a laptop, streaming freely, or sharing across a trip. All three run for 30 days on Telkomsel, Indonesia's largest network, and if you misjudge it you can buy a top-up instead of starting over, so it is safe to pick the smaller plan when you are unsure. See the plans or the Bali eSIM page for the full detail.

The only way to be certain

Your own habits beat any estimate, including this one. Your phone already tracks mobile data use in its settings (Cellular on iPhone, Network or SIM usage on Android). Install your eSIM before you fly, switch it on when you land, and check the number after your first two days. If you are using less than you feared, relax. If not, you have days of warning to top up rather than a nasty surprise at the end. It is a far better guide than any table.
