The install fee is a one-time $65 charge plus $15 to port an existing number. The service is $21.25 per month plus taxes and fees.  You can omit the $15 port fee if you wish to be assigned a new phone number for this landline.  This service is UNLIMITED local and long-distance calling.  If you have a need for international service, we have a plan for this as well — just let me know.

Please find below two links regarding our phone service.  The first link is for the digital telephone agreement for the service.  The second is for the port of your existing phone number from your current carrier to ours.  Please be sure that your “failover number” is a good working number in case there is an issue during the port process.  This is the number that your phone calls will be rerouted to in the meantime.
