Can I keep my existing phone number when switching to Optus Prepaid Mobile?
Yes, you can keep your existing phone number when switching to Optus Prepaid Mobile. This process is known as number portability. To successfully transfer your number, you will need to initiate the porting process when you sign up for an Optus Prepaid plan. It is important to ensure that your current mobile service is active and not canceled, as this will allow the porting process to occur smoothly.
When you start the process, you will typically be required to provide the account details from your current service provider. This information may include your account number and possibly some identification. Optus will then take care of contacting your old provider to facilitate the transfer. The porting process usually completes within a few hours, although it can take up to a day in some cases.
For the most accurate and up-to-date information, refer to the official Optus website, as it will provide detailed guidance on number portability and any specific steps you may need to follow.
