Openline works across Australia on Tier-1 partner networks — currently Telstra, Optus, Vodafone/TPG. In practice you're routed to whichever of those has the strongest signal for your specific location, which is typically 5G in Sydney, Melbourne, Brisbane and 4G/LTE across the rest of the country.

What to expect

  • Speed: 5G where available. Typical download speeds of 50–300 Mbps in major cities on 5G, 20–100 Mbps on 4G/LTE.
  • Coverage: country-wide across populated areas. Very remote regions may fall back to 3G.
  • Latency: low enough for video calls in urban areas.

Plans

  • Country plan for Australia — cheapest for a single-country trip. Data options from 1 GB to Unlimited.
  • Regional plan covering Australia plus its neighbours — best for multi-country itineraries.
  • Global plan — if you're travelling widely.

Buying

Search "Australia" on openline.com, pick your data and days, and pay by card, wallet, PayPal, or crypto. Install the eSIM before flying — activation happens automatically on arrival.

Local tips

  • Keep your home SIM in and let Openline handle data — you'll keep receiving 2FA and iMessage on your home number over the Openline data path or Wi-Fi.
  • Data Roaming must be on for the Openline line even though there is no roaming charge to you.
  • In Sydney 5G is dense enough that turning off Wi-Fi and using Openline directly often outperforms local hotel Wi-Fi.

Still stuck?

Reach Openline support 24/7 through any of these channels:

When you write in, include your purchase code (the OL-… code we emailed you) and, if the eSIM is already installed, its ICCID (Settings → Cellular → tap the Openline line). That's enough for us to find your plan and diagnose without back-and-forth.
