Similarities will exist between many companies, not just these sister companies. Since each has it's own separate web site, it's own branded handsets that cannot be used with the other company (some exceptions) and especially since Tracfone is so much different than the others; I think they should each have their own forum.
Net10 has pretty much separated itself from Tracfone with monthly plans, byod etc. And now they have officially announced a data cap which ST has not.
You wouldn't group all companies that have a BYOD plan, so why group Net10 and ST just because they share the same street address/phone number.
