The Sydney Streets, hiking in the Blue Mountains, and watching the perfect Gold Coast Sunset, you need to visit Australia. You have a dream to travel through Australia, and you are all set! 

But what have you decided about the connectivity? How are you gonna share all those memories with your social circle? If considering international roaming on your physical SIM, do you have enough budget?

Roaming charges from your home provider can be shockingly high. Local SIM cards might seem like an alternative, but who wants to spend time hunting for one at the airport or a mobile shop when you're jet-lagged? 

You're going to need an eSIM. Yes! A perfect connectivity companion that kills all the hassles and sky-high roaming fees. Not just any eSIM, it should be the Defy Mobile eSIM. Why? 

Let’s learn about Defy Mobile for Australia eSIM plans and how it might be the best travel upgrade you have ever made!

Is our Phone eSIM Compatible with Australia’s Mobile Networks?

Before jumping in, let’s make sure your device supports eSIM technology. Most recent smartphones, including iPhone 13 models and up, Google Pixel 4 and newer, and high-end Samsung Galaxy phones, are eSIM-ready. Some other companies like Huawei, Oppo, Honor, and OnePlus + are also offering some eSIM-compatible variants.

To check eSIM device compatibility:

  • On iPhone: Go to Settings > General > About > Carrier Lock

If it says "No SIM restrictions", you're good to go.

  • On Android: Go to Settings > Network & Internet Connection > Mobile Network > Advanced

If you see options for eSIMs or network switching, your phone likely supports eSIM.

Also, some phones support dual SIM (eSIM + physical SIM card), so you can keep your home phone number active while using a Defy Mobile eSIM.

How to Set Up and Activate Your Defy Mobile eSIM in Australia?

Getting started with your travel eSIM should feel as easy as checking into your hotel. Here’s how to activate Defy Mobile eSIM and enjoy seamless data access across Australia.

Follow these easy steps to set up your eSIM before or after arrival:

  • Choose Your Plan: Pick from Defy Mobile eSIM for Australia-specific data plans or go with a global option if you're continuing on to nearby countries like New Zealand or Southeast Asia.
  • Check Compatibility: Make sure your phone supports eSIM technology. Almost all recent models (iPhone XS and up, Google Pixel 3 and newer, Samsung Galaxy S20+) work just fine. Check here!
  • Buy & Receive QR Code: Once you purchase your plan, you’ll instantly receive an email with a QR code and manual activation code, so you’re covered even if your camera doesn’t work. 
  • Scan the QR Code: Open your phone settings, go to Cellular or Mobile Data, and tap Add eSIM. Then simply scan the code provided.
  • Manual Activation Option: If scanning isn’t possible, you can manually enter the activation code in your device settings. This works well in offline scenarios or poor lighting.
  • Stay Connected: Within seconds, your digital SIM activates and your phone connects to a local Telstra network or Optus network, offering premium coverage nationwide.

Tip: If you're travelling to multiple Australian cities, install the eSIM before you fly. No more airport SIM card hunts or language hassles.
