   AT&T turned off 2G in 2017.  The other carriers plan to turn it   
   off this year about the same time as they turn off 3G.  They are   
   desperate to free up bandwidth for 5G.   
      
   Here's an odd turnoff story: I have an unlocked Samsung S9 phone I   
   have been using with an AT&T Tracfone SIM. Tracfone was recently sold   
   to Verizon and they are migrating all of their users to VZ SIMs and   
   all of their voice traffic to VoLTE. They sent many warnings that my   
   AT&T SIM would stop working when they turned off 3G, even though it's   
   a 4G phone. They also insisted that my phone wouldn't work on their   
   Verizon 4G network because it doesn't support VoLTE.   
      
   Whaddaya know, they were right, it didn't work with their VZ SIM. So I   
   switched to Ting, another VZ MVNO, and it works fine and says VoLTE is   
   turned on. I am baffled -- Tracfone has no reason to cripple my phone   
   but for some reason their SIM did just that.  The phone was originally   
   from Comcast, another VZ MVNO, and I wonder if VZ has some rule about   
   not poaching their resellers' phones.
