I’m very happy with my new phone. The whole process was very easy - arrived safely at the post office. I’m not expecting any problems - but it’s good to have the warranty.

ElizabethVerified buyer · 31 October 2026

Bought an Iphone 15 pro as good but it looks excellent. I also choose the 100% battery and it is. Basically perfect, such a bargain.

Paul P.Verified buyer · 30 October 2026

I bought an iPhone 13 just to give it a try. I didn't expect it to be this good—it's even better than described. From now on, I'll only buy phones here.

Hongyue W.Verified buyer · 29 October 2026

Phone quality as promised. Arrived as on time. Great selection.

Brad S.Verified buyer · 29 October 2026

Great service, fast response and the refurbished phone is as good as new at half the price.

Jo O.Verified buyer · 29 October 2026

Ozmobiles has done it again. Great prices and fantastic iPhone 16 pro max. Just like new. This is my fourth iPhone from them. Brilliant work from Ozmobiles. Delivery was fast and well protected.

Ray P.Verified buyer · 28 October 2026

Great used phone for a great price. Quick delivery with notifications.

Johan D.Verified buyer · 28 October 2026

Looking to upgrade from Samsung S10+ and found this S24 Ultra at OzMobiles. This suited me as the cost of current models is totally exhorbitant! Phone arrived quickly in excellant condition. My only comment on this phone is the lack of availability to use an SD Card which means downloading data etc when you need to release more memory. Note:- This was avalable on the S10+
