Understanding Network Locked Phones
Ever bought a new mobile only to find your mate’s SIM card won’t work in it? You’ve likely encountered a network locked phone. A network locked, or carrier locked phone, is a device that has been restricted by a mobile provider to only work with their SIM cards. If you have a phone locked to Telstra, for example, it simply won’t recognise a SIM from Optus or Vodafone. This is a common practice in Australia, especially when you get a phone on a plan. Carriers do this to ensure you stick with their service, particularly if they’ve sold you the handset at a subsidised price or as part of a prepaid deal. Unlocking your phone gives you the freedom to switch providers, find better deals, and use local SIM cards when travelling, which is essential for managing mobile data abroad. It’s also a crucial step when buying a second-hand phone to make sure it’s not tied to the previous owner’s provider. This guide will walk you through everything you need for a successful mobile unlock.
Summary
This guide provides a complete walkthrough on how to unlock your phone from any Australian carrier in 2026. You’ll learn what a network-locked phone is, how to check if your device is locked, and the step-by-step processes to unlock it for free from major providers like Telstra, Optus, and Vodafone. We also cover specific instructions for iPhones and Android devices, advice for unlocking US-based phones, and answer frequently asked questions to ensure you have all the information you need.
TLDR
- Check Your Lock Status: The easiest way to see if your phone is locked is to insert a SIM card from a different carrier. If it asks for an “unlock code,” it’s locked.
- Contact Your Carrier: In Australia, your carrier is the best and safest source for unlocking. They are often required to do it for free if your contract is over.
- Have Your IMEI Ready: You’ll need your phone’s unique IMEI number. You can find this by dialling *#06# on your phone.
- iPhone vs. Android: The unlocking process is different. iPhones are unlocked remotely by the carrier, while Androids usually require you to enter a code manually.
- Third-Party Services: Use these with caution. While some are legitimate, many are scams. Unlocking directly through your provider is always the preferred method.

How to Check if Your Phone is Unlocked
Before you try to unlock your phone, it’s a good idea to confirm whether it’s locked in the first place. Many phones sold in Australia today, especially those on postpaid plans, already come unlocked. Here are two simple methods to check your phone’s status.
Method 1: The SIM Card Swap
This is the most straightforward way to check. All you need is a SIM card from a different network. For instance, if your phone is from Telstra, borrow a friend’s Optus or Vodafone SIM.
- Turn off your phone and eject your current SIM card.
- Insert the SIM card from the other carrier.
- Turn your phone back on.
- If the phone connects to the new network and you can make calls, it’s unlocked! If you see a message like “SIM Not Supported,” “Enter Network Unlock Code,” or “SIM Network PIN,” your phone is locked to your original carrier.
Method 2: Using Your IMEI Number
Your phone’s International Mobile Equipment Identity (IMEI) is a 15-digit code unique to your device. You can use this to check the lock status.
First, find your IMEI by dialling *#06# on your phone’s keypad—the number will appear on the screen instantly. You can also find it in your phone’s settings under “About Phone” > “Status”. Once you have it, you can use an online IMEI check Australia service or contact your carrier directly and provide them with the number to confirm the lock status. Using your IMEI to see if phone is unlocked is a quick and reliable method.
How to Unlock Phone from Carrier for Free
In Australia, unlocking your phone is a consumer right, and the process is usually simple and free, especially if you’ve completed your contract. Here’s how to approach it to unlock phone for free.
The standard and most legitimate way is to contact your mobile carrier directly. Under the Telecommunications Consumer Protections (TCP) Code, providers must give you the unlock code free of charge if you’ve finished your contract period. For prepaid devices, a small fee might apply if you request an unlock within a certain period of first using the service (e.g., within the first 6 months).
📋 What You’ll Need
To process your request, your carrier will typically ask for the following information:
- Account Holder’s Details: The name, date of birth, and possibly the account number of the person who originally signed the contract.
- Your Phone’s IMEI Number: Dial *#06# to get this 15-digit code.
Having this ready will make the process to unlock phone free with IMEI number much smoother. Most carriers have an online portal or a dedicated phone number for unlocking requests.
Unlocking Guides for Major Australian Networks
Each Australian network has a slightly different process. Here’s a breakdown of how to unlock your device from the big three and other providers as of 2026.
