It is super simple to add a line of service to your account. Family members need phones too! Just log in to your Twigby account. From there, click on the add a phone tab (circled in blue below). Then just follow the steps. These are the same steps used for adding the first line to the account, so they should look familiar! If you have any questions, please chat with us by clicking the orange CHAT NOW button below. We are here to help!
