The Sony Xperia Z3+, which was announced back in May this year and started rolling out globally last week, is now available for purchase in the US. Amazon is offering the unlocked version of the handset in black, white, copper, and aqua green colour variants, with prices starting at around $650. The dual-SIM variant is also available. Another point worth mentioning is that the models being offered will only work with GSM carriers (for example, AT&T and T-Mobile).
Over in the UK, it is now officially available on Sony Mobile Store, which is selling the unlocked version in all the aforementioned colour variants for £499, with standard delivery taking 3-5 working days. On the other hand, Amazon UK has the black and white colour models (unlocked) listed for £495.
As you might know, the Z3+ is plagued with over-heating issues, but the good news is that Sony has finally released an update to fix the problem.
