Does Optus lock phones?
The policy distinguishes prepaid locked devices from postpaid devices and modern iPhones.
Who is eligible for an unlock?
- Optus can unlock only an Optus-sold device that is locked to its network.
- Prepaid cost depends on recharge and activation history.
- A non-customer fee can apply under the current policy.
How to request or confirm an unlock
- Have IMEI 1 ready.
- Use the Optus web tool or 9999 SMS menu.
- Follow the model-specific code or activation instructions; manufacturer lookup can take additional business days.
iPhone, Android and unlock codes
Not every unlocked Optus phone is compatible with another network.
Do not repeatedly enter a code that is rejected.
SIM and eSIM information
SIM or eSIM compatibility is separate from whether the handset has been network unlocked.
If the unlock or SIM test fails
- Update the phone software before testing another SIM.
- If Optus cannot find a code, follow its manufacturer-request timing rather than using a third party.
