I recently purchased an Australia eSIM through Klook for my trip, and overall, I was very satisfied with the experience. As someone who relies heavily on mobile data for navigation, ride-hailing apps, social media, messaging, and staying connected with family and friends, having reliable internet access throughout the trip was extremely important. The booking process on Klook was straightforward and user-friendly. After completing the purchase, I received the eSIM details and installation instructions almost immediately. The instructions were clear and easy to follow, making the setup process quick even for someone who was using an eSIM for travel. I was able to install the eSIM before departure and activate it once I arrived in Australia, which saved me the hassle of searching for a local SIM card at the airport.

had a really smooth experience using an eSIM for Australia that I purchased through the Klook app. The whole process was incredibly convenient—from booking to activation. Right after purchase, I received clear instructions, and setting up the eSIM took just a few minutes with no need to visit a store or swap physical SIM cards. Coverage was excellent throughout my trip. The connection was stable, fast enough for navigation, video calls, and even streaming without frustrating interruptions. What I appreciated most was the flexibility. I could choose a plan that matched my travel duration and data needs, and everything was transparent—no hidden charges or complicated terms. Overall, it made traveling so much easier. No hunting for local SIM cards, no language barriers, and no stress. I’d definitely recommend using an eSIM through Klook for anyone visiting Australia—it’s a simple, reliable, and hassle-free.

Easy set up and fast connection. I did an online purchase in Klook prior departure from ATL and the moment I landed Sydney, I just turned my phone on and got connected to the local Optus provider. Unlimited data browsing and usage was a breeze. Absolutely helpful when using the maps. There was a little bit of a spotty slow connection when we drove up the Blue Mountains (of course as expected since mountains always have a tricky spot). Instead of staying within the motorway, our map had a delay and we ended up driving through a back road. We got rerouted to enter back the motorway 30mins later, but heck yeah it was a beautiful countryside view we had for few minutes! What an adventure! Overall the signal was satisfactory to keep us updated.

Was I hesitant at first? Absolutely. Am I now a full-blown fan? 100% YES! I’m so glad I took the leap and got this E-SIM AUSTRALIA OPTUS from KLOOK. I activated it before my trip, and—like magic—it only kicked in when I landed in Australia 🇦🇺. No fuss, no stress, just instant connectivity. 📶 The signal? Flawless. From the busy streets of Sydney to the scenic corners we explored, the 5G was strong and steady. No dropped calls. No loading circles. Just smooth-sailing browsing, navigating, posting, and Googling where to eat next. 😎 ⭐ 5 stars from me! I’ll definitely grab this again on my next adventure. Travel smart, stay connected—highly recommended! ✨📱

Generally the esim has awesome internet speed and coverage and I would recommend this esim to anyone travelling to Australia plus it is very easy to use and activate. Rxcept for when you are on train or land travel as it sometimes lag or cuts off. i hope they sell it with a tied up Australian phone number so when you dont have data you can still be easily reached.

How can I activate the eSIM directly from the Klook app?

  • Tap the “Activate” button and wait for the eSIM to get activated.
  • After activation, make sure the eSIM is installed on your device. You can check it from Settings > Cellular > SIMs.
  • You can name the eSIM in Settings > Cellular > eSIM > Cellular Plan Label.
  • Note: Be careful not to turn on the data roaming before arriving at your destination!
  • After arriving at the destination, please turn on eSIM data roaming and switch the cellular plan to this eSIM card to connect to the network.

How can I activate the eSIM with a QR code?

You can find the QR code from the booking details on the Klook app or on your Klook account.

The QR code should be visible next to the "Activate" button if your device is compatible with the eSIM and the eSIM plan. If not, you can scan the QR code with a device that is eSIM compatible by following these steps:

  2. Name the eSIM at your convenience from the "Cellular Plan Label."
  3. Do not turn on data roaming until you arrive at your destination

Android

Network & Internet > SIMs > Add Cellular Plan

The eSIM didn't get activated on my device. What should I do?

Check if your device is locked to a carrier, as eSIMs can't be activated on locked devices. Please contact your carrier for more information.

Can I scan one QR code with multiple devices?

No. You can use the eSIM only on one device. As such, one QR code can't be used multiple times or on multiple devices. Make sure to scan the QR code and activate the eSIM on the device you intend to use it on.

Should I turn on data roaming when I'm using the eSIM?

Yes. Make sure to turn on data roaming after you arrive at your destination. You can toggle it on from the eSIM settings.

An error occurred while I was installing the eSIM. What should I do?

The solutions depend on the error message you saw:

  • Cellular Plans from This Carrier Cannot Be Added:

Your device might be locked to a specific carrier. Please double-check from Settings > General > About > Carrier Lock. It should say "No SIM restrictions." If that's not the case, contact your original carrier to unlock the restrictions of your device.

  • Unable to Complete Cellular Plan Change:

It might be because too many eSIMs are installed on the device. Please double-check if your device has reached the maximum eSIM capacity, which eSIM service is on it, and try removing one of the unnecessary eSIMs.

Please make sure to turn on the mobile data on your device.

Please make sure that the eSIM plan hasn't been installed on another device.

Please make sure you have a stable connection while you're installing the eSIM.

  • This code is no longer valid:

Please make sure that the eSIM plan hasn't been activated on another device.

Please make sure you have a stable connection while you're installing the eSIM.

Try installing the eSIM using a different activation method. (There are two methods: In-app activation and QR code activation. You can try either on the same phone.)
