While checking my Fi account, noticed upgrade offer for Samsung A71 5G for $299 and for new customer with port in $199 with 90 days service.
A71 MSRP - $599
New customers get $400 off Samsung Galaxy A71 when you buy and activate on Google Fi. Existing customers can upgrade and receive $300 off.
Trade in will reduce this price much lower. I tried with iPhone 8 which shows estimated value as $100. For new port in, final price will be $99 with trade in iPhone8.
