How to Unlock Optus iPhone

iPhones purchased through Optus usually already come unlocked, whether prepaid or postpaid. However, any Optus iPhones sold before September 11th, 2013, will need unlocking, which you can do free of charge.

Once again, if you have an iPhone with an iOS 7 or later or an iPhone 4 or higher, no extra steps are necessary, it’s already unlocked. If you have not updated your phone to iOS 7, you simply need to update the phone to unlock it for free.

Do not worry if you have an iPhone 3 or older. You will have to restore the phone with iTunes to get it ready for unlocking. Please take note that restoring your iPhone through iTunes will wipe it, so back up everything before proceeding.

How Much to Unlock Optus Device

Sometimes you will have to pay a fee to unlock your phone, whether because you have not upgraded your iOS or because you have not recharged your plan enough times yet.

You will also need to pay a few if you fill out a form to help unlock your phone.

Prepaid Optus Phone

  • If you have already spent $80 or more in recharging your phone’s prepaid plan, Optus will unlock your phone for free.
  • If not, you will pay an $80 fee (for a plan that is less than six months active) or $25 (for a plan that has been active for more than six months).

However, it is a slightly different story with tablets or other mobile broadband.

Prepaid Optus Tablet

  • If you have been activating your device for 12 months or longer, you can unlock the device free of charge.
  • If it has been less than that, you will not be able to unlock the Optus device until you spend an accumulated $100 or more recharging the plan.

That total will not include any included value you received in your initial starter kit.

Postpaid Phone
