The Sony Xperia Z3 came out in 2014. Probably not: only the T-Mobile version had VoLTE, and it's no longer reliably supported.
The quick answer
- Calls: no
- Software: Android 6
- Still works offline for some features
- Worth keeping as a collectible
Why it can't connect
The T-Mobile Z3 supported VoLTE, but T-Mobile has dropped support for many older phones. The Verizon Z3v relied on CDMA. Unlocked international versions lack US VoLTE.
What still works
It's waterproof and the camera still works, but Android 6 can't run most current apps.
What it's worth
Values are low.
If you're replacing it
A new moto g 2026 or Galaxy A17 costs little, gets years of updates, and several carriers give them away when you switch. Pair it with a low-cost plan such as Mint Mobile ($15 a month for 6GB on a 12-month term) or Visible ($25 for unlimited, taxes included).
Current offers from Metro, T-Mobile, Verizon, AT&T and Xfinity.
