AT&T Says It Will Be 'Disruptive' With Cricket

That's funny. I'm not the most up-to-date on ATT's network, but I'm pretty sure they don't have VOLTE working nationwide. It's going to be kind of hard to just flip a switch where millions of CDMA phones suddenly do their voice calling over a GSM network. And even if they do have blanket VOLTE coverage across the US, I seriously doubt that most cricket phones support it. I imagine that in 3 or 4 years they can have Cricket's customers all migrated over to their network, but that's hardly overnight.
