Compared: The best eSIM for Bali in 2025
Bali is a tropical paradise that is much-loved by Australian tourists.
However, too many Australians still pay too much to stay connected while visiting the Indonesian island.
International roaming fees charged by most Australian mobile networks are a rip-off, and huge savings are available for those who opt for a travel eSIM instead.
So what is the best Bali eSIM for 2025?
We’ve put together this guide, which looks at four of the most popular providers, to help you make your own decision.
How does a travel eSIM work?
An eSIM is a virtual SIM card that can be easily installed on most modern mobile phones, including Apple and Android devices.
You can leave your physical SIM card from your Australian mobile network in your phone and have it work in tandem with an eSIM to access data while travelling overseas.
Most eSIMs are very easy to install through mobile phone apps for different providers.
Why choose a Bali eSIM for your trip?
Travel eSIMs offer many benefits for Australian travellers, including:
Convenience: You can set up an eSIM before you depart Australia so that you are connected as soon as you land at Denpasar International Airport.
Cost-Effective: Travel eSIM’s can be a fraction of the cost of Telstra international roaming plans, as well as roaming options from other Australian mobile networks.
More Options: Whether you are a heavy mobile data user or only expect to require a little bit of data during your Bali travels, there are suitable eSIM plans to suit your needs.
Bali eSIM v Telstra International Roaming
Telstra charges $10 per day for international roaming in Bali, which includes 2GB of data each day as well as unlimited calls and SMS.
However, depending on your data needs, Australian travellers could instead get away with paying less than $1 per day for a travel eSIM in Bali.
