Yes, customers generally can keep their current phone number when switching to Cellular One. This process is known as number porting. It allows you to transfer your existing phone number from your current provider to Cellular One without having to change it. To ensure a smooth transition, it is important to check with Cellular One for any specific requirements or procedures they may have regarding number porting. It is recommended to have your account information from your previous provider on hand, as this may facilitate the process.
