The Best Phone and Internet Options For Your Bali Travels

If you’re planning a trip to Bali, get ready for an incredible adventure! One thing you’ll absolutely need, though, is a reliable way to stay connected. Whether it’s navigating the island, keeping in touch with loved ones, or sharing your journey on social media, a dependable phone and internet setup can make all the difference. Here’s a complete guide to staying connected in Bali - from the top mobile networks and eSIM options to managing IMEI registration for longer stays.

Best Mobile Networks in Bali


Bali's mobile coverage is generally good in most tourist spots, though you might find some remote areas with weaker signals. Here’s a breakdown of the top networks:


Why it’s the best: Telkomsel offers the widest coverage across Bali, including more remote areas like Nusa Penida and the Gili Islands. If you’re planning on exploring beyond the main tourist hubs, this is your go-to.

Cost: Plans start around IDR 100,000 (~$10 AUD) for 25–30 GB. This should be enough for most travellers, covering your data needs for social media, maps, and browsing.


Why it’s good: XL Axiata offers solid coverage in urban areas like Denpasar and Kuta, plus good 4G speeds in tourist hotspots.

Cost: Plans begin at IDR 50,000 (~$5 AUD) for about 20 GB. This makes it an affordable option for short stays or minimal data usage.


Why it’s worth considering: While it’s not as widespread as Telkomsel, IM3 Ooredoo still delivers reliable service in most popular tourist areas.

Cost: Plans start at IDR 50,000 (~$5 AUD) for 10–20 GB, so it's another budget-friendly option if you're sticking mainly to the cities.


Why it’s cheaper: Smartfren offers decent coverage in more popular tourist spots, but you might run into issues in more remote areas.

Cost: You can get 10 GB for just IDR 30,000 (~$3 AUD), which is great for anyone on a tight budget or staying in a specific area.

SIM Cards vs. eSIMs: What’s the Best Option for You?


When it comes to staying connected in Bali, there are two main options: physical SIM cards and eSIMs. Here’s the breakdown to help you decide which one’s best for you:


Physical SIM Cards

You can buy a prepaid SIM card when you arrive at the airport or at local stores throughout Bali. Just make sure to bring your passport, as they’ll need it for registration. 

SIM cards are super easy to swap out and get working right away, but you’ll need to be cautious of losing your original SIM if you travel a lot.


eSIMs

If you have a phone that supports eSIMs, they can be a fantastic option. You don’t have to physically swap out a SIM card, and you can activate it before you even arrive in Bali, so you’re all set the minute you land.

International eSIM providers like Airalo and Holafly offer plans that work well in Bali, with packages starting at $8 AUD for 5–10 GB. Just make sure your phone supports eSIM before purchasing an eSIM plan - most recent models do, but it’s always good to double-check.

IMEI Registration for Long-Term Visitors


If you’re planning to stay in Bali for more than 90 days, you’ll need to register your phone’s IMEI (International Mobile Equipment Identity) number with the Indonesian authorities. Here’s what you need to know:


  1. Who Needs to Register

    • If you’re staying less than 90 days, you’re good to go - no registration required.

    • For stays over 90 days, you’ll need to register your phone to continue using it on local networks.


  2. How to Register

    • Take your phone and passport to an official store or customs office. The one located at the airport is the most convenient for registration when you arrive. They’ll need to input your IMEI into their system to authorize your phone.

    • Be aware that there is a fee depending on your phone’s value. For phones worth more than $500 you will need to pay 40% of the remaining value after a $500 deduction. For example, if your phone costs $900, you pay 40% of $400, or about $160. 


  3. What Happens if You Don’t Register?

    • After 90 days, your phone will be blocked from accessing local networks, so you’ll need to register it if you want to continue using it.


  4. Alternatives

    • If the whole IMEI process sounds like a hassle, you can opt for an eSIM or rely on international roaming plans.

Pro Tips for Staying Connected in Bali


  1. Skip the airport SIM card stalls. They’re convenient, but prices are usually quite a bit higher than what you’ll find in local stores.

  2. Look for free Wi-Fi. Many cafes, hotels, and coworking spaces offer free Wi-Fi - just make sure you use a VPN for security.

  3. Download offline maps. Internet can be spotty in remote areas, so it’s always a good idea to have your maps saved offline.


Whether you’re in Bali for a quick getaway or a longer stay, staying connected is easy and affordable. With plenty of SIM card and eSIM options, and clear steps to follow for IMEI registration, you’ll have no problem staying in touch, navigating the island, or sharing your amazing moments with the world.


If you feel like you're being offered an unreasonable price for a SIM plan or worry you’re being overcharged as a tourist, make sure you check out Tengah. Tengah is the ultimate travel app that ensures you’re getting a fair deal. It shows average prices for bartered goods and services based on what other travellers have paid. Plus, it provides photos, descriptions, and currency conversions all tailored to your location. 


Happy travels!
