Can I use my cell phone in Bali?
Yes, you’ll be able to use your phone abroad as long as it’s unlocked from your home carrier and supports GSM and 4G LTE networks, which all modern phones do.
If you’re traveling from Australia, in particular, the same conditions apply. All major Australian network providers, like Telstra, Optus, and Vodafone AU, operate in Bali via roaming.
Telstra roaming in Bali
As a Telstra user in Bali, you can stay connected with a Day Pass or a Pre-Paid International Roaming Pack. Otherwise, you’ll be subjected to standard pay-as-you-go rates.
- Day Pass for Indonesia (Zone 2): $10 AUD for 2 GB, unlimited calls and SMS
- Pre-Paid International Roaming Packs: $10-25 for 3, 7, and 14-day travel packs, which include 400 MB to 4 GB data allowance, 15-50 SMS/MMS, and 15-50 voice minutes.

If you’re on any of the following plans:

You can choose Optus Daily Roaming to use data, call, or text in Bali. You’ll get 5 GB of data per day, plus unlimited calls and texts, for $5/day.
For other plans, you can purchase a daily Optus Roaming Pass for Bali. This includes 1 GB of data allowance per 24 hours and unlimited calls and texts for $10 per day.
Prepaid roaming packs include 1 to 10 GB data allowances, 100-700 minutes, and 100 texts for $5-20. For more details on exact packs for Bali, visit our Optus roaming guide.
The last option would be to settle for Optus’ standard roaming rates: $1 per MB, $1.50 per voice minute, $0.50 per sent SMS.
Vodafone AU roaming in Bali
If you’re not on a roaming-inclusive Vodafone AU plan, you still have two options to stay connected in Bali.

What is the best way to use your phone in Bali?
Roaming with your home provider may seem like the convenient option, but it’s not so easy on the pocket. Charges can quickly rack up, especially if you’re a heavy-data user. Luckily, there are other ways to stay connected.
Travel eSIM for Bali
Downloading an eSIM in advance is the easiest way to get mobile data before the trip. Activate it online by scanning a QR code, and enjoy access as soon as you land.
eSIM providers like Holafly offer unlimited data in 200+ destinations, including Bali, with flexible eSIM plans and fixed prices. Holafly’s Always On feature includes 1 GB of monthly backup data at no extra cost, keeping you connected even after your eSIM expires. Simply keep the eSIM installed to avail the extra data every month.
Local SIM card in Bali
If you need a local mobile number for calls, a Bali SIM card might be worth it. These are available at Ngurah Rai International Airport at airport kiosks, local providers, convenience stores, and stalls across tourist areas. You will have to present your passport and register your phone’s details on arrival.
Things to know before you use your phone in Bali
Before you arrive in Bali, here are some practical tips to keep in mind:
- IMEI registration: Indonesian law requires IMEI registration for foreign devices that remain in Indonesia for more than 90 days. If your trip is shorter than this, you won’t need to do anything.
- WhatsApp accessibility: WhatsApp works seamlessly on local networks with an eSIM, physical SIM, or roaming services.
- Network coverage: In major cities and tourist areas like Seminyak, Kuta, Ubud, and Canggu, you can expect excellent coverage. However, this may get patchy in more remote areas.
- Download offline maps: It’s a good practice to download them in Google Maps before traveling to rural areas where the signal might dip.
- WiFi and VPN: You can find free public WiFi in most hotels, cafes, and restaurants. When using public WiFi hotspots, protect your data with a secure network connection. Check out our blog on the best VPNs in Indonesia to explore options.
Will your phone work in Bali? The verdict
Yes, your phone will work in Bali. The real choice comes down to how much you want to spend on mobile data, calls, or texts. Relying solely on international roaming can get expensive fast.
For most travelers, getting a Holafly eSIM for Bali allows the ultimate peace of mind: unlimited data, 24/7 customer support, and 5G speeds. If your trip includes other destinations in Indonesia, get Holafly’s eSIM for Indonesia instead.
Peace of mind before you fly
