What is an eSIM and does your phone support it?
An eSIM (embedded SIM) is a digital SIM card built directly into your phone’s hardware. Unlike a physical SIM, it can be activated remotely by scanning a QR code — no SIM tray, no tiny card, no fumbling at the airport.
Compatible devices include:
- iPhone 14 and newer (all models)
- iPhone 13, 12, 11 and XS/XR (some eSIM support)
- Samsung Galaxy S23, S24, S25 series
- Google Pixel 7 and newer
- Most flagship Android phones released after 2022
Check compatibility: Settings > General > About (iPhone) or Settings > Connections > SIM Manager (Samsung).
Dual SIM advantage: Keep your Australian number active for calls and SMS while using the travel eSIM for data — no need to give up your Australian number.
The 5 best eSIMs for Australian travellers in 2026
1. Airalo — Best overall
Coverage: 170+ countries Best for: Most travellers — cities, popular tourist destinations, Asia, Europe, Americas Pricing: From USD $4 for 1GB/3 days; global plans from USD $8.50 for 1GB/7 days; unlimited plans available
Airalo is the world’s largest eSIM marketplace — and for most Australians heading overseas, it is the default recommendation. Its 170-country global coverage, reliable 5G speeds in major cities, one-tap top-ups and dual-SIM compatibility make it the safest choice for first-time eSIM users and experienced travellers alike.
Points Brotherhood (July 2026), written specifically for Australian travellers: “for most Australian travellers, Airalo is the one I reach for. It isn’t always the cheapest to the cent, but the coverage, the dual-SIM trick, and the fact that I’ve run it across more than a dozen countries without drama make it the safe default.”
Strengths: Widest coverage; competitive pricing; easy top-ups; works on Optus 5G in Australia Weaknesses: Customer support slower than Holafly; longer plans (30+ days) more expensive
2. Holafly — Best unlimited data
Coverage: 142+ destinations Best for: Heavy data users, remote destinations, travellers who want peace of mind Pricing: From USD $24.90 for unlimited/3 days; scales to 90+ day plans
Holafly’s defining feature is unlimited data — no caps, no throttling. If you are working remotely, streaming, video calling or uploading while travelling, unlimited removes all anxiety about running out of data mid-trip. Trustpilot rating: 4.6/5 — one of the highest in the eSIM industry.
Strengths: Genuinely unlimited data; runs on Telstra in Australia (widest rural coverage); 24/7 live chat support with fast response times Weaknesses: More expensive than Airalo for similar trips; coverage of some Asia-Pacific destinations more limited
Discount: 5% off with code ANDREAONDIGITAL (confirmed August 2026)
3. Saily — Best budget + security
Coverage: 150+ countries Best for: Budget travellers; those who want built-in security features Pricing: From USD $3.99; unlimited 15-day plan from USD $48.99

Gizmodo (July 2026): “Saily is the best eSIM for Australia overall. It delivers 5G, uncapped tethering, an ad blocker, a virtual location tool and airport lounge access in the app.”

Strengths: 200+ destinations; most flexible billing options; reusable eSIM profile; offline top-ups Weaknesses: Less known than Airalo or Holafly; app experience less polished

Do I lose my Australian number when using a travel eSIM?
