Hello all, I’ve just moved into a property (rather old) and I have two landline “boxes”. One newish one connected to an old one with blue and white wires. The new box has orange and white and green and white. Only the orange ones are connected inside the box. Can I get rid of the blue ones? I don’t intend on having a land line and don’t particularly want WiFi (good mobile data package). Help us greatly appreciated for this house newbie!
