Who I have the same questioned this topic

I'm probably going to leave Verizon for a less expensive service provider (USMobile) (which happens to use Verizon towers). I'd like to find out if I'll still be able to use Message+ (which I currently use with Verizon) in the same way, if it will have the exact same functionality; and specifically if I'll be able to receive text messages to the phone number on laptop when the phone is off (like I currently can with Verizon).
