Yes, it is possible to keep your current phone number when switching to Google Fi. This process is known as number portability, and Google Fi supports it for most carriers. To initiate the transfer, the user will need to have some key information on hand, such as the account number and the PIN associated with the existing phone service. It is important to ensure that the current service is active during the porting process, as deactivating the account before the transfer is complete can result in losing the phone number. Typically, the transfer can be completed within minutes, but there can be cases where it may take longer. As always, it is advisable to consult the current Google Fi website for specific instructions and to verify any additional requirements related to number portability.
