# Bali SIM card or eSIM from the UK: roaming costs and the Denpasar airport question

The best eSIM for Bali depends on what your UK network charges in Indonesia. EE charges £26.50 for a 7-day pass in ROW Zone 1, Sky £2 a day and Vodafone £8 a day (checked on 24 October 2026, [EE price guide](https://ee.co.uk/content/dam/help/terms-and-conditions/price-plans/mobile/sim-only-price-plans/_ee-pay-monthly-standard-and-non-standard-price-guide-31st_March_2026_1.1.pdf)). Our Bali (Indonesia) eSIM from the UK is £2.99 for 1 GB over 7 days, data only. You have four ways to stay connected: your UK network, a travel eSIM, a local SIM or pocket Wi-Fi.

This site is not affiliated with any of the networks mentioned here; we sell eSIMs. [How we compare](https://esimworld.co.uk/how-we-compare/)

You may not need us. O2 Ultimate plans and Three Complete include Indonesia, and Sky VIP Diamond customers roam free (checked on 24 October 2026). For a short trip, Sky's £2 a day or Lyca's £5 pass (1GB, 7 days) can be enough.

## What do UK networks charge in Bali and Indonesia?

Roaming in Bali (Indonesia) on UK networks costs £2 a day on Sky, £26.50 a week on EE and £5 per MB on Tesco Mobile (checked on 24 October 2026). Your network's zone sets the price. EE, O2 and Talkmobile give no data in Indonesia without a pass.

Per-MB rates add up fast. At Tesco's £5 a MB, 100MB costs £500. iD's £45 limit buys about 12MB (our arithmetic). Vodafone, Three and Sky charge for each day you use the phone, not each day away.

Your network's page is the final word on your plan. Our guides to [EE](https://esimworld.co.uk/roaming/ee/), [Vodafone](https://esimworld.co.uk/roaming/vodafone/), [O2](https://esimworld.co.uk/roaming/o2/) and [Three](https://esimworld.co.uk/roaming/three/) give full rates.

## Bali SIM at Denpasar airport or eSIM?

A SIM from a Denpasar airport shop is bought after you land and gives you an Indonesian number; we have not checked its price. An eSIM installs at home: ours is £7.99 for 5 GB over 30 days, data only. Two weeks on your UK network cost £28 on Sky and £112 on Vodafone (our arithmetic).

| Network or plan | 14 days | 21 days | How we added it up |
|---|---|---|---|
| EE, ROW Zone 1 | £53 | £79.50 | 2 or 3 weekly passes |
| Vodafone, pay monthly from 11 August 2021 | £112 | £168 | £8 a day of use |
| Three, Lite and Lite+ from 18 December 2025 | £60 | £90 | 14-day pass; + 7-day pass £30 |
| Sky, not VIP Diamond | £28 | £42 | £2 a day of use |
| Lyca, pay as you go | £10 | £15 | 14-day pass (2.5GB); + 7-day pass (1GB) £5 |
| Lebara | £12 | £16 | 15-day add-on (3GB); + 8-day add-on (1GB) £4 |
| Our Bali plan, data only | 5 GB, £7.99 | 5 GB, £7.99 | one 30-day plan; 10 GB is £10.99 |

Prices: each network's own page, checked on 24 October 2026. Totals: ours.

These are different products. Network passes use your UK allowance and number. Our plan is a data-only eSIM on a second line, and calls stay on your UK SIM ([keeping your UK number](https://esimworld.co.uk/help/keep-your-uk-number/)). [Roaming or eSIM](https://esimworld.co.uk/roaming-or-esim/) covers the choice for any country.

The Bali (Indonesia) SIM card vs eSIM choice comes down to where you buy it. A local SIM is sold in person, so bring your passport. We have not checked airport stock, prices or the Indonesian IMEI registration question. Pocket Wi-Fi is one more device to carry and charge.

Our plan needs no ID check, only an eSIM-compatible phone. Dial *#06#: if an EID shows, it takes one. [How to install an eSIM](https://esimworld.co.uk/how-to-install-esim/) has the steps.

## Bali and Lombok on one plan

Our Indonesia eSIM lists Bali, Java, Lombok and the Gili Islands, so a trip from Ubud to Lombok needs one Bali eSIM, not two (plan listing, checked 24 October 2026). The listing says cover is not limited to those four but names no others, so on Nusa Penida or Flores keep Wi-Fi as a backup.

Local networks: Telkomsel and Indosat Ooredoo, both marked 5G in the listing. We give no 4G/5G coverage map or speeds.

Our GB and days plans run from 1 GB over 7 days to 20 GB over 30 days. Each starts on first connection to a network in Indonesia, not at purchase, and you can install it up to 365 days after purchase. Install [before you travel](https://esimworld.co.uk/help/before-you-travel/), on home Wi-Fi.

On landing, pick the travel line for mobile data and turn [data roaming on](https://esimworld.co.uk/help/data-roaming-settings/) for that line only. Keep it off on your UK line. That stops data charges, not every charge: on Sky, a call or text you make still starts the £2 day.

We state no hotspot rule for this plan, so check the plan card before you use hotspot and tethering.

The Foreign, Commonwealth & Development Office (FCDO) last updated its Indonesia advice on 18 September 2026 (checked 26 October 2026). It says: "Volcanic eruptions occur frequently across Indonesia." Read the full [FCDO travel advice for Indonesia](https://www.gov.uk/foreign-travel-advice/indonesia) before you book.

## Frequently asked questions

### Is it worth getting an eSIM for Bali?

Yes, if your UK network charges by the day or the MB in Indonesia. Sky charges £2 a day, EE £26.50 for 7 days and Vodafone £8 a day (checked on 24 October 2026). A data-only eSIM covers a week or a month for one price. Keep your UK SIM for calls.

### What is the best eSIM for Bali?

There is no best eSIM for Bali on price alone, and we rank no seller. For data, pick the GB and days you would use at home and install before you fly. For calls on your number, use your UK network's pass. For an Indonesian number, buy a local SIM; we have not checked its price.

### Do you need a SIM in Bali?

No, but without one you depend on Wi-Fi. Without a pass, EE, O2 and Talkmobile give no data in Indonesia; Vodafone, Three and Sky charge by the day; giffgaff, iD, Tesco, SMARTY and Asda charge per MB (checked on 24 October 2026).
