The S3, EVO LTE, and S4(pre spark) could do it fine because they had 2 radios. They were sold around the time AT&T and T-Mobile were marketing the ability to do Talk and Data at the same time.
Since that time has passed, the new Spark Phones will not be able to do Talk and Data until VoLTE is enabled.. Yay!
It is a step back so I will be keeping my EVO LTE around incase I need the ability more often then not. :/
