Are you tired of your old phone number? Do you want to change your number on your O2 contract? Don`t worry, it`s easy and straightforward. In this article, we will guide you through the process step by step.

Step 1: Contact O2 customer service

The first thing you need to do is contact O2 customer service by calling 202 from your O2 phone or 0344 809 0202 from any other phone. You can also visit an O2 store or use their live chat feature on their website. Once you are connected, explain to the customer service representative that you want to change your phone number.

Step 2: Verify your account information

To change your phone number, you need to verify your account information with O2 customer service. This is to confirm that you are the account holder and have the necessary permission to make changes. You will be asked to provide your name, address, and other relevant details.

Step 3: Choose your new phone number

Once your account information is verified, the customer service representative will then provide you with a range of available phone numbers to choose from. You can select the number that best suits your preferences.

Step 4: Confirm your new phone number

After selecting your new phone number, the O2 customer service representative will confirm your selection and ask if you are happy with the chosen number. If you are happy, they will then finalize the process and activate your new phone number.

Step 5: Wait for the switchover

Once you have chosen your new number, it can take up to 24 hours for the switchover to take effect. During this time, you will still be able to use your current phone number. However, after the switchover, your old number will no longer be in use, and all calls and texts will be directed to your new phone number.
