The Straight Talk Wireless Home Phone plan does not require a connected land line. It will work with your disconnected phone.
Yes you can use your existing home phone. Just disconnect the wire coming from your wall jack from your current home phone. The Straight Talk phone unit will have a new wire in the box to connect to the back of the Straight Talk unit that is labeled 'PHONE" the other end of the wire is plugged into the jack on your phone. After you plug in the power cord and wait for the signal lights to lite up (need two of the three for good service) you can follow the instructions to set up your service by using a separate cell phone and the manual that comes with the unit. You will need to make a refill purchase during the set up. Use a credit card for this.
jerni, Straight Talk does not support (nor recommend) that you use your existing phone jacks by "backfeeding" it though your existing wiring. However, many have done so successfully. If doing so, you have to make sure that the wired service coming into the house has been completely disconnected and disabled.
The recommended manner to use the Straight Talk Wireless home Phone and what Straight Talk DOES support is to plug your corded phones into the back of the device (and not using the existing wall jacks in your house at all).
There are two jacks/ports on the back of the Straight Talk Wireless Home Phone device. You can plug two corded phones into the back or use a cordless phone system where you would plug the base station into the Straight Talk Wireless Home Phone device and then use multiple handsets in different rooms in the house.
So, NO, you do not have to have a land line connected. The Straight Talk Wireless Home Phone works totally independent of your current land line. It is a cellular-based unit and needs to be within an adequate distance from a Verizon Wireless cell tower (this uses Verizon for service).
