I'm a Google Fi customer and experienced a very disconcerting fraud attack a year or 2 ago. I made an outbound call to the support number for my bank (I triple-checked that it was the correct number for the bank's support line). My call was routed to fraudsters impersonating my bank's support and I gave them all of my debit card information through what I initially thought was an authentication process. The 1) strange call quality, 2) that they asked for all of my card details and 3) the lack of an automated menu tipped me off and I realized pretty much immediately after the call was over that I had been scammed. I called the exact same support line a second time and got the actual customer service for my bank, at which point I promptly canceled my debit card (but not before the fraudsters performed what appeared to be a test charge of my card for $5 to a random merchant name in Connecticut). I had no idea this kind of attack was possible and I don't know how it works or whether it was related to the T-Mobile breach. Had the hackers attempted an account takeover using the information they collected from me they could conceivably have stolen all of my savings.
