Google Fi is a great and economic service, it provides low rates and transparent billing, you know your service is pretty good when it is provided by Google,

Great ‘new’ news: 
Google Fi no longer requiers the number be ported to a mobile line first, you may port directly from us to Google Fi, Porting will take between 3-5 days, though we’ve seen it port sometimes the same day. 

(But just like Google Voice, Fi only allows mobile numbers to be ported into their system, and since 212 numbers are primarily landlines, we’ve set up a nice (and free) workaround for you, here’s how we’ll make it work for your new 212 phone number:

We’ll port the number you purchased into a mobile carrier, and of course, there’s no extra charge for this, but keep in mind that it will take approximately 3-5 days to complete, and as soon as the number is ready for porting into your Google Fi account, we’ll send you concise and clear instructions along with all the relevant account information on how to complete the port to Google Fi.)

So, you should be well on your way to selecting a new 212 phone number for Google Fi: Start browsing for a new number today.
