If you let your VL account expire, then you lose your number, and will not be able to port
If you want to port from VL, you need to choose a provider
(if you want to port to GV, you will have to port to a mobile phone first)
You MUST keep your VL account paid up and current in order not to lose your Phone Number.
You MUST not cancel your VL account if you want to keep your number
If and when you port your number, the act of porting your number will cancel your old provider (in your case VL)
In case I have not been clear
If you let your VL account expire, then you lose your number, and will not be able to port
(and you lose your number- did I mention that?)
You MUST not cancel your VL account if you want to keep your number
