About this ZDC × Three unlock

Three locks devices to its network when sold on contract or financed. Unlocking your ZDC is straightforward once your account meets Three's eligibility criteria — typically the device must be paid off and not reported lost or stolen.

DeviceDecoded uses the manufacturer's official unlock channel. We submit your ZDC's IMEI directly, and once approved, the device is permanently whitelisted. The unlock survives factory resets, OS updates, and SIM swaps.

Three country coverage

Three operates in 9 countries. Your ZDC unlock works regardless of which country it was originally sold in.

  • 🇦🇺 Australia
  • 🇦🇹 Austria
  • 🇮🇪 Ireland

FAQ — ZDC on Three

Can Three block this unlock?
No. Once your ZDC's IMEI is whitelisted on the manufacturer's database, Three cannot reverse it.
Will my ZDC stay unlocked after a factory reset?
Yes. The unlock is permanent at the factory level — it persists through factory resets, OS updates, and SIM changes.
Do I need my Three account credentials?
No. We unlock by IMEI alone. You don't need to provide your Three username, PIN, or account number.
What if my ZDC is still on a Three payment plan?
It depends on the device's status. Start with the eligibility check at our unlock checkout — that page explains how the two-stage payment works before you commit.
