Carrier unlocks are an incredibly useful thing that benefits mobile phone owners in a lot of ways. At first, having a locked phone isn’t the worst thing in the world.

Generally speaking, if you sign a contract with O2 then you shouldn’t be surprised that your phone will be locked to the network for a while. But after a contract expires, some people like having the option to use a separate carrier and usually because it works out cheaper.

To do this, you must unlock O2 phone and we’re going to be explaining how this works.

  • Android smartphones bought from O2 after the 1st of January 2019 should be unlocked
  • If you bought an Alcatel or Doro brand device from O2, it won’t be unlocked

Now onto the first method, the approach we recommend the most – using a carrier unlocking service to unlock without O2 account.

  • The fastest way: usually get your phone unlocked within 24 hours

Part 3. Unlock O2 Phone with Unlock Code (Up to 14 Days)

On the other hand, you can request an unlock code from O2. This will cost you a pretty penny and it’ll take longer than a service, but it’ll unlock O2 phone anyway.

3.1 How to request O2 unlock code?

Step #1 – Go to O2 unlock request page.

Step #2 – Fill out the form with your phone’s details.

Step #3 – After providing the information requested, wait until O2’s team contact you.

Step #4 – O2 will contact you with further instructions on how to complete the unlock.

That’s as straight forward as it gets, but getting your unlock code can take 2 weeks maximum, so if you’re in a hurry this isn’t the ideal way to unlock O2 iPhone.

3.2 How Can I Receive Unlock Code?

If you are an iPhone owner then O2 will text message you the unlocking code with instructions on how to proceed. For Android owners, an email will be sent instead.

Simply follow the instructions after you receive the text or email and then switch out the O2 SIM card with another carrier’s SIM card.

3.3 Why I Cannot Get an Unlock Code?

Basically, for O2 to provide customers with an unlock code, they have to contact the device’s manufacturer. Newer devices like iPhones and Samsung Galaxy models don’t usually take a long time, but older models can take as long as 10 working days (2 weeks) before the code is received and you can unlock O2 phone.

3.4 Cons of using O2 Unlock Code

  • It can take a long time (10 working days) for O2 to provide the unlock code
  • If you’re not currently in the UK, you won’t be able to use O2’s unlocking service
  • O2 are only able to unlock phones that were bought from them


That wraps up everything you need to know in order to unlock O2 phone successfully. Keep in mind all of the benefits of doing this, as well as the methods for approaching this task, and you won’t run into any problems along the way.

Our recommendation is that you use DirectUnlocks O2 unlock, a service that is known for successful phone unlocks. Using a flawless process, there’s no doubting it as the best way to unlock any phone from any carrier.
