Phones don't get hacked, but phone accounts do. Just google "simjacking" or "Sim swap fraud". All it takes is a little social engineering to get the representative at your phone company to move your number to a new phone, and now all the 2FA and password recovery texts from your bank are going to the scammer. T-Mobile has been hit with this pretty hard recently because scammers are able to use the data from the data breach to get into people's accounts.
