For travelers exploring the world in 2025, eSIMs—digital SIMs embedded in your device—offer a seamless, cost-effective alternative to physical SIMs and expensive roaming fees from providers like Telstra, Optus, or Vodafone. Whether you’re wandering Bali’s beaches, navigating Tokyo’s bustling streets, or working remotely in London, the right eSIM keeps you connected effortlessly. With the eSIM market evolving, I’ve reassessed the top providers based on recent web insights, focusing on coverage, pricing, usability, and reliability for Aussies traveling to popular destinations like Southeast Asia, Europe, and North America. Recent sources highlight Eskimo as a strong contender, so I’ve added it to the list.
1. Airalo: The Global Leader
Airalo tops the list with coverage in 200+ countries, including Aussie favorites like Japan, Thailand, and Europe. Its Asialink plan (18 Asian countries) ranges from AUD 7.30 (USD 5) for 1GB over 7 days to AUD 269 (USD 185) for 100GB over 180 days. Global plans cover 136 countries, up to 20GB for a year. Setup is easy: download the Airalo app, select a plan, scan a QR code, and connect. Payments include credit cards, Apple Pay, or Google Pay, with 5% Airmoney credits on purchases. Airalo partners with local networks like Optus (Australia) and Singtel (Singapore) for reliable 4G/5G.
Reviews praise Airalo’s fast 5G in urban Asia and Europe, ideal for navigation or social media. However, data-only plans require WhatsApp or iMessage for calls, and heavy users may need top-ups.
2. Holafly: Unlimited Data Champion
Holafly excels with unlimited data plans in 160 countries, including Australia, Bali, and the US, starting at AUD 28 (USD 19) for a week of unlimited data in Asia or Europe. Installation is straightforward via the app or QR code, with payment options like credit cards, PayPal, and Google Pay. Holafly connects to local networks like Optus (Australia) and AIS (Thailand) for 5G speeds. Tethering isn’t supported, so each traveler needs their own plan.
Reviews highlight Holafly’s reliable 5G and 24/7 support, perfect for streaming Netflix or working remotely. Its higher cost and lack of hotspot functionality are drawbacks for groups. Holafly is ideal for data-heavy Aussies seeking worry-free connectivity.
3. Jetpac: Asia-Pacific Specialist
Jetpac, a Singapore-based provider launched in 2022, covers 200+ countries with a focus on Asia-Pacific (e.g., Malaysia, Indonesia). Plans start at AUD 1.46 (USD 1) for 1GB over 4 days, up to AUD 57 (USD 39.50) for 40GB over 30 days. Setup is simple via the Jetpac app, with perks like free lounge access for flight delays and a 30-day ExpressVPN trial. Jetpac offers 4G/5G via local networks.
Reviews praise Jetpac’s affordability and reliability in Southeast Asia, including remote areas like Indonesia’s islands. Its bot-driven support can be less responsive. Jetpac is great for Aussies on regional getaways or budget-conscious trips.
4. Saily: Budget-Friendly with Security
Saily, backed by NordVPN, covers 200+ locations, including Australia and Thailand, with plans starting at AUD 2.80 (USD 1.95) for 1GB. Setup is intuitive via the app with QR code activation, and features like a built-in VPN and ad blocker save up to 28% on data usage. Saily connects to local networks for 5G-ready speeds, ensuring smooth performance for emails or social media.
Reviews commend Saily’s low costs and security, though coverage is slightly less extensive than Airalo’s, and support can be slow. Saily suits budget-conscious Aussies on short trips needing secure connectivity.
5. Eskimo: Long Validity and Data Sharing
Eskimo, a newer player, offers coverage in 130+ countries, including Australia, Japan, and Thailand, with a unique 2-year data validity period. Plans start at AUD 5.80 (USD 4) for 1GB, up to AUD 131 (USD 90) for 30GB, with tethering supported. Setup is quick via the Eskimo app, with direct installation or QR code activation. Eskimo connects to local networks like Optus (Australia) for 4G/5G and allows data transfers to other users, a rare feature. New users can try 500MB free with code “KT33933”
Reviews praise Eskimo’s long validity (the only provider with a 2-year validity), single-install eSIM for multiple countries, and data-sharing feature, ideal for travellers revisiting destinations or traveling in groups. Eskimo is perfect for long-term travelers or those sharing data.
6. Yesim: Unlimited Data Alternative
Yesim covers 160+ countries, including Australia, New Zealand, and Europe, with unlimited data plans starting at AUD 11.30 (USD 7.7) for 7 days. Setup is easy via the app or QR code, with payments via credit cards or PayPal. Yesim offers consistent high-speed 4G/5G via local networks, with tethering allowed in some plans, unlike Holafly.
Reviews highlight Yesim’s reliable unlimited data for work or heavy usage, though it’s more expensive than fixed-data options like Jetpac or Saily. Yesim is a great alternative for Aussies needing unlimited data with hotspot flexibility for trips to Asia or Europe.

- Buy Early: Purchase and install your eSIM before leaving Australia to avoid airport Wi-Fi dependency.
