While hotels in Bali offer free Wi-Fi, mobile data is still essential when you’re out and about, needing to look up information, navigate, check in, or upload photos.

There are three ways to get mobile internet in Bali:

First, rent a 4G portable Wi-Fi device; second, use international roaming; third, purchase a local SIM card in Bali and top up for data.

Renting a 4G Portable Wi-Fi Device

If you’re considering renting a 4G portable Wi-Fi device for use in Indonesia/Bali, check out our Klook Bali 4G Portable Wi-Fi.

Take this high-speed 4G Wi-Fi device with you wherever you go. Whether you’re at the beach, a restaurant, or a tourist spot, as long as you have this device, you can stay connected without relying on public Wi-Fi.

Using International Roaming

The second option is to use international roaming, which has become quite affordable these days. It’s recommended to check with your telecom provider for their international roaming packages, as there are usually multiple options available. The advantage of using your original number for roaming is that you don’t need to change SIM cards or rent a WiFi device, saving a lot of hassle.

Purchasing Local SIM Cards

Additionally, for those staying longer in Bali or requiring more data usage, it’s advisable to get a local SIM card and purchase data packages, which can be more cost-effective. Just bring your passport to register, and it’s best to have your driver take you to avoid being scammed.

SIM cards and data packages bought at the airport are the most expensive, with some people paying up to three times the normal price! Therefore, it’s recommended to go to an outside store. Since they need to register your passport, having your driver take you ensures you go to a legitimate store, preventing identity theft or being overcharged.

In Bali, Telkomsel, the state-owned Indonesian telecommunications company, offers the best signal for local SIM cards, for your reference.
