Adding Phone to my Broadband only Package

[#1]

Hi All,
I have the broadband only package at present and was thinking about adding my phone to Plusnet too from BT to save some money.
If I add the Evening and Weekend call package, does this mean that I can only use the phone in the evening and at weekends and what happens if I need to make a call during the day at peak hours?  Is it worth getting this package or the unlimited package and paying £5.00 extra for this?
Thanks

The evening and weekend package means that outside that time you will pay for the calls http://www.plus.net/home-broadband/tariffs/
Whether the anytime version  is better for you depends on the use of your phone outside evening and weekends

Okay, thanks Jim.  I might start with the Evenings and Weekends and see how it goes.  Just seems sensible to keep everything under one roof and it will be cheaper as BT are increasing their line rental from December.
