HOW IT WORKS You own cellular number is your account with Primo Call; you get a passcode in SMS message or a phone call to authenticate you. Default calling method is Local Access, when you dial a phone number or choose one from your contacts; dialer attaches this number to a local number on our servers and dials that number. (Your Wifi/Data internet connection will be used for this local number setup). This local number automatically connects the call to the long distance number you originally dialed. If you have chosen “Callback” as calling method; when you dial a number or choose one from your contacts, dialer will send this number to our servers and our server will send you a call back on your phone number and connect this call to the number you originally dialed. Last but not the least is the “Internet” calling which makes the call using Wifi/Data internet connection without using allocated minutes from your provider. Internet dialing is also the best choice while you are roaming out from your provider’s coverage and have an internet connection available to you.
