Found this today and it’s a decent saving for anyone heading to Indonesia.
Klook charges $35 AUD for the 15‑day / 20GB Indonesia eSIM.
Switch the currency to IDR and it becomes 199,626 IDR.
Pay with Wise (~12,500 IDR per AUD) and it’s about:
≈ $15.97 AUD
Same product. Half the price. Klook’s AUD conversion is cooked.
And then there's Cashback:
ShopBack currently offering 20–21% on Klook and eSIMs are eligible.
Changing currency doesn’t void it as long as you:
Start from ShopBack AU → Klook AU
Keep your Klook account country = Australia
Stay on the AU domain
Don’t use promo codes
Note:
Currency change on Klook-
Works best for eSIMs
Some activities/spas also cheaper in IDR
Transfers don’t seem to move the needle
Use Wise/Revolut/etc.
Easy 50% saving for anyone going to Indonesia.






I always use https://esimdb.com/ find the cheapest esim for the time I am going, and data I will need and install it.
Never had a problem and a lot cheaper than this as I normally need 3 esims per trip.
