Does Fi have a way to require a pin code for SIM card replacement? To prevent phone number hijacking

Can Fi require a pin number to issue a replacement SIM card for my phone number? The goal is to prevent phone number hijacking. Thanks!

Since your Fi phone number is tied to your Google account, your account would need to be hijacked before your phone number could be.   I could mail you my  physical sim but you wouldn't be able to activate it on your phone without having logged into my Google account.

So, I'm not sure what a PIN adds to the equation.

Howdy do
 
No. The SIM [Subscriber Information Module] cannot be directly written to by the User.

This would be a pin that Google Fi support requires in order to ship out a new SIM. No writing to the SIM by the subscriber.

If Fi phones cannot be hijacked or are more resistent, this is a strong selling point for the service. There continue to be stories of exploits against one's phone number. Scary. Happy to be avoiding this particular pitfall of modern technology.

To protect your phone better you should also enable two-step verification for your Google account, starting at https://myaccount.google.com/security.  But! remember to print out the backup codes and store them somewhere safe that you will remember, so you can still get into your account if you lose your phone.
