Learn how to transfer your number with a step-by-step guide.

What you need to know about transferring

How long it takes to transfer a number

You’ll start the transfer once you open the Fi app to activate your phone.

  • Mobile numbers usually transfer within 24 hours.
  • Google Voice and landlines can take a few business days.

Check to see if you can transfer your number to Google Fi in the section below.

Eligibility, family plans, & keeping your number

How do I know if my number can be transferred? When you sign up for Google Fi, we'll tell you if your number can be transferred.

If I’m on a family plan, can I transfer my number? Yes. Keep in mind that depending on your current plan, this may impact the other people still on the family plan. We recommended calling your carrier to check.

If I transfer my number, can I take it with me if I decide to switch carriers? Yes. You can cancel your Google Fi service and transfer your number to another carrier at any time.

Can I activate Google Fi service with a new number and transfer my number later? Yes. Once your Google Fi account is active, you can contact support to start the process.

Can I use my own phone and transfer my number? Yes. Download the Google Fi app and follow the instructions to sign up or start your transfer.

Using your number while it’s being transferred
  • You can still use your old phone for calls and texts until your transfer completes. You’ll also be able to use data on your active phone while the transfer is happening. Once the transfer completes, you get a notification on the phone you use with Fi.
  • If you bring your own phone to Fi, you can use your old SIM card.

What to do before you start the transfer

Keep your current phone service active

Don’t cancel your current phone service. It needs to be active for the transfer to go through. Once your transfer is finished, you’ll also want to make sure your plan with your previous carrier is canceled. Many carriers will cancel it automatically after you transfer out your number, but you should still check with the carrier.

If your phone is new, make sure to keep your previous phone around. While the transfer is happening, you can still use your previous phone for calls and texts until the transfer completes.

Check if there are any early termination fees

If you’re under contract with your current carrier, check if there are any early termination fees. If so, you might be charged a fee for leaving your contract early. If you have questions, contact your current carrier.

Check transferring fees. Check if your current carrier charges any fees for transferring out your number.

Make sure your number is unlocked & ready to transfer out

To make sure the transfer request is authorized, some carriers have locks on customer’s numbers. To make sure your number is ready to be transferred, go to your current carrier’s website or app and sign in to your account. To make sure the number is unlocked and ready to be transferred out, follow their steps.

If you can't find where to check if the number is unlocked, you may need to call your current carrier for assistance.

AT&T port protection

To start a number transfer, make a Number Transfer PIN. Use that PIN to initiate the number transfer on the Google Fi website.

After you initiate the number transfer, you may get a text message from AT&T that asks you to confirm the transfer. Once you respond to the text message, retry the number transfer. 

If you do not receive a text message from AT&T, make sure that your AT&T service is still active and that your AT&T SIM card is still in your device.
