You do not need a landline connection from BT to get a Swale Life connection.
Once you have Swale Life internet service you can cancel your BT Broadband connection and just keep your landline telephone. As a basic option this should be less than £10/month.
It is possible to get rid of your BT service completely and use IP telephony – so called VoIP (voice over internet protocol) which runs on SIP (Session Initiation Protocol). There are many ways of doing this – please start a conversation with us – they can be very cheap.
You can get a new number with 01748 STD or you can move your BT landline number to the SIP supplier.
In addition you can use WiFiCalling within your house using your mobile – this works well with EE.
