A:Answer I did this when I got my phone Galaxy s5. My mother wanted a smart phone & needed a new phone anyway. My contract wasn't up until another yr so I found out I could add another line & still get the phone. Once the phone came, I had already synced my phone contents to the Verizon cloud so I downloaded them to the new S5. I logged into my Verizon account & clicked Switch Device to switch my phone number from my old phone to the new phone & then my old phone has the new phone number & the s5 has my old number. During the process I had to swap sim cards between the phones. I reset my old phone & gave it to my mom. Doing this increased my bill by about 40 something dollars each month because both devices are on a shared plan..unlimited talk/text 6 GB data, I got the 6 gigs of data through a promotional call since it was free. I think I originally had 3 gigs of data. So if you're willing to shell out an extra 40 something bucks each month & a higher bill the first month after you buy the phone due to the prorating & surcharges, then go for it. It would be even better if you have someone you trust that you could let use the 2nd line with your old phone & maybe they could even pay you each month for use. If you have someone use your old phone, make sure you erase & reset it. Then go through the setup & make sure that person uses their own Google account or create one & input their payment info so you don't get stuck with paying for their apps. Well good luck!
