Transferring an existing Optus Prepaid balance to a new number is generally not supported by Optus Prepaid Mobile. Typically, prepaid balances are associated with the specific mobile number on which they were activated. If you obtain a new number, the remaining balance on the old number cannot be directly transferred to the new account.
However, it may be possible to use the old number and new plans or services if you choose to keep the existing number. Customers often consider closing the old account once the balance has been fully utilized. For specific policies and options tailored to your situation, it is advisable to check the current Optus Prepaid Mobile website for detailed information. This ensures you have access to the latest guidelines regarding balance management and number transfers.
