Again. Read my post. The subsidy was good on the original mobile share plans if you had 4 or more lines.
ATT has kinda of rigged their mobile share to make it look like no subsidy is cheaper by INCREASING the rates and than claiming a $25 savings if you pay in full or next or BYOD.
The carriers will do what's best for them. And making plans cheaper PER LINE is not one of them.
Verizon stopped reporting PER LINE revenue a couple of years ago cause PER LINE revenue was going down.
It's all a shell game with carriers these days and "family plans".
If they just offer POSTPAID euro/Asia single line plans we wouldn't have this conversation.
They rely on post paid FAMILY plans for most of their consumer revenue.
