Yes you can add 2 lines on 1 phone. It works on any Verizon phone or any service. I just signed up for a service called secondvoice. It's cell phone Service, it offers a second phone line on a single cell phone. It works for me. Keep my buisness and personal call seperate. Perfect for the small business owner. check it out. Its great to have two numbers on one cell.
This is a VERY interesting service and one that I can see might be handy for some. However, I think a couple of things should be clarified. First, this is NOT a second line "IN" your phone. That is just not possible with Verizon (at least not with full call in and out service). It is however a third party service that established a second number for you and when someone calls that number that call is ROUTED to your phone by the service. You do have a second number and separate voice mail but that number and voice mail has ZERO to do with Verizon. It just has the appearance of two lines on one phone. It's very important that members understand this.
Voice mail for that second line will NOT go to your Verizon voicemail but to a second voicemail box the service sets up for you. In reality this is just a third party that establishes a second phone line for you elsewhere and merely TRANSFERS those calls to your phone when a call comes in.
You cannot make any emergency phone calls (911) with that second line. You will NOT get a detailed bill of your calls either from them. Verizon will bill you for minutes used for all of those calls coming in and out to and from that second service. This will be in addition to the $14 bucks it will cost you a month for Second Voice to give you this service. Honestly, Verizon can give you a second line and number for just $9.99 . . . it's called a Family Share program LOL! The only difference there is you'll have two phones. Some will view a second phone to carry as a drawback.
Frankly, I'd get a second tiny phone that shoves easily in a pocket and go that route. I view this method as an advantage because if one phone goes down or loses reception you've got a second small phone in your pocket! It's what I do now . . . two lines - two phones - one bill and company to deal with and it's cheaper! Still . . . this is an interesting option and some people may like it
Oh believe me I tried that, just as a bunch of others have and we all got met with the same response . . . NOPE! Theoretically, with Nam1 and Nam2 it should be possible but Verizon's policy is they won't do it. Give 'em a call now and ask. That will be the response.
The response they give me and pretty much everyone else is they want one MEID/ESN number associated with one phone line for security and fraud reasons. At one point I asked to have an extension phone "one number shared by two phones" similar to what you would have on a landline. They gave me the exact same response. They want ONE phone identified with ONE MEID/ESN at a time. You can read their verbiage about this online as well. Here it is below. This is for the Extension phone question but it is the same response they'll give you for two lines on one device as well:
Does Verizon Wireless offer extension phones?
We have thoroughly weighed the costs against the benefits of offering this feature. We have made the decision not to offer the capability to use two wireless phones with one wireless phone number. The current wireless system we use identifies the wireless phone's Mobile Equipment Identifier (MEID) and matches the MEID with the wireless phone number. This process is integral to our system as it helps protect against wireless phone misuse and fraud.
