Spark's Wireless Broadband, Portable, Rural and Fibre service don't use a copper connection or phone jack points. You can use portable cordless phones if you need multiple phones at your location.
Your existing phone calling will work as normal when plugged into the back of the modem. If it's a cordless (DECT) phone, you’ll still need to have the base station connected to power. If you have multiple phones in other rooms that are connected via the jack point in the wall, these will not work.
If you want to use multiple phones, we recommend using a cordless (DECT) phone with multiple handsets.
