Yes, customers can typically keep their existing phone numbers when switching to Altice Mobile. This process is commonly referred to as "porting" a number. To initiate the porting process, customers usually need to provide specific information from their current service provider, such as the account number, PIN, and possibly other personal details. It is advisable to ensure that the account with the existing provider is active, as it may need to be active for the porting to be successful.
While the porting process generally goes smoothly, it can sometimes take a few hours to a couple of days for the number to be fully transferred. During this time, the current phone service may remain active until the port is completed. For additional details, it is recommended to check the current web page for more information on the requirements and steps involved in the number porting process.
