If you had let's say the the Nationwide 450 plan as well as the Unlimited Texting with Mobile to any Mobile Calling plan and got a call from a CELL PHONE, then nope it wouldn't count against your minutes. If you got a call from a LANDLINE, then yes, it would count against your minutes.
Now let's take the same example above, but no unlimited texting with mobile to any mobile calling, if you had gotten a call from a cell phone or landline, yes it would count against your plan.
