The way the told me is once my land line stops working then then my Connect will be activated. Was told to leave the Connect off until my land line is cut off or it might cause some type of delay. So really I'm not without a phone for 10 days. I also know the person I was dealing with at the store was a new person nor did I think about asking for a temporary number. But he did tell me if I used a different number, and then wanted to use my home number, I would have to bring back the unit to be reprogrammed. I don't think that was right, but I went with the flow of things. Just keep in mind they told me 2-3 day for port, but I think in reality it's about 10 days for a land line. But your landline will work until the port occurs.
