A practical, step-by-step guide for getting connected in Bali reliably, keep costs under control and stay compliant while working remotely.
Step-by-step plan
- Check your phone: ensure it’s unlocked and supports Indonesian bands. If unsure, confirm with your manufacturer or seller before travel.
- Decide physical SIM vs eSIM: eSIMs can be purchased online before arrival; physical SIMs are sold at the airport, convenience stores and official provider shops. Consider eSIM for immediate arrival convenience and physical SIM for easier top-ups locally.
- Buy & register: purchase at the airport or provider store (Telkomsel, XL, Indosat, others). Expect to register with passport details, have your passport and a clear selfie ready to confirm identity; requirements may vary so confirm locally.
- Choose a data plan: start with a short tourist pack if you’re unsure, then switch to a monthly package for remote work after you settle. Test speed and reliability from your accommodation.
- Set up top-ups: install the provider’s app, or use local payment apps or convenience stores to top up credit. Save the app and your login for remote troubleshooting.
- Backup & fallback: keep a small second SIM (or an eSIM with a separate provider) as a backup for meetings or when visiting areas with patchy coverage.
- Review regularly: re-evaluate your plan after the first month, data usage and coverage needs become clearer after a few work weeks.
Documents & requirements
- Passport: bring the original; many sellers will ask to copy passport information for registration.
- Visa details: keep your visa stamp/permit handy; some registration systems may ask for visa type.
- Clear selfie / biometric photo: some providers verify identity with a selfie or live photo. Have your camera ready.
- Unlocked device: your phone must be unlocked to accept another network’s SIM.
- eSIM-capable device (if choosing eSIM): confirm device supports eSIM profiles and compatible bands.
- Payment method: cash (IDR) is widely accepted for in-person purchases; set up an Indonesian-friendly card or local payments for app top-ups.
- Local address (optional): some sellers may ask for a local address; your accommodation address is normally fine.
Requirements may differ between stores and providers. Always confirm current registration rules at the point of sale.
Costs & budget notes
Below are typical price ranges to budget for data and SIMs. These are estimates and may change so confirm locally before purchasing.
| Item | Typical cost (approx.) | Notes |
|---|---|---|
| Physical SIM purchase | Free–IDR 20,000 (~£0.80) | Often free with a small starter top-up; airport kiosks sometimes charge more. |
| Tourist data pack (short stay) | IDR 50,000–200,000 (~£2–£8) | Valid 7–30 days; suitable for initial arrival and testing coverage. |
| Monthly data for heavy remote use | IDR 200,000–600,000 (~£8–£24) | Unlimited calls + generous data bundles available; costs vary by speed and provider. |
| eSIM purchase (prepaid) | From ~IDR 50,000 (~£2) upward | Convenient to set up before arrival; check roaming/eSIM provider terms. |
If you’re working remotely full-time, plan for 100–300GB+/month depending on video calls and uploads. Consider a fixed broadband option for long-term stays.
Common pitfalls & how to avoid them
- Buying the wrong SIM: confirm the SIM size (nano/micro) or choose eSIM to avoid fit issues.
- Unregistered phones: ensure your device is unlocked and supports Indonesian frequencies before leaving home.
- Poor coverage expectations: coastal towns and central tourist areas have good 4G, but remote parts of the island may be patchy so test coverage from your accommodation.
- Running out of credit during a meeting: set auto-top-up in the provider app or keep an emergency backup SIM/eSIM.
- Not keeping documentation: keep digital copies of passport and registration details for troubleshooting or re-registration.
- Using public Wi‑Fi for sensitive work: treat public networks as untrusted; use a VPN for remote work and banking.
- Assuming long-term plans are cheaper: short promo bundles often expire, review monthly plans after arrival to secure the best value.
FAQs
Can I use my UK number in Bali?
Your UK SIM will work only if you enable international roaming so expect higher costs. For regular work, buy a local SIM or eSIM for better rates and local numbers. Consider forwarding or keeping your UK number active for essential calls.
Do I need to register my SIM with my passport?
Most Indonesian providers require identity registration for SIM activation. Be prepared to show your passport and possibly take a selfie for verification; practices can vary, so confirm at the point of sale.
Are eSIMs reliable for remote work?
Yes, eSIMs are convenient and work well in urban areas. For critical meetings keep a secondary option (physical SIM or another eSIM) as backup, especially when travelling to less-covered parts of the island.
Which provider has the best coverage in Bali?
Major national providers generally cover popular areas reliably. Coverage quality can differ by neighbourhood. Test reception from your accommodation and choose the provider that performs best locally.
How do I top up credit from abroad?
Use the provider’s app, authorised resellers, or international top-up services. Setting up local payment options once you arrive is usually simplest for recurring top-ups.
Will 5G be useful in Bali?
5G availability is growing in main towns, but 4G remains the most widely accessible technology for consistent work. 5G can help with high-throughput tasks where available, but don’t rely on it island-wide.
