It has not happened yet but will do by default.
I rarely use my landline for outgoing calls. I am with Plusnet on a 'free calls at weekends' basis. I find their wifi is great so I am happy to stay with them, but it seems that if I want to retain my landline I have to switch to EE for both landline and broadband.
The reason I would prefer to keep my landline is that my mobile is by default on silent. This is because otherwise I would forget to turn it off during church services, rehearsals etc, occasions where it would be extremely dispruptive. So my family know that if they need to speak to me urgently they need to ring my landline which , if I am at home, I can hear anywhere in the house. Even if I have my mobile switched on, I might not have it beside me all the time around the house, so I might miss a call.
I also give my landline number to tradesmen, GP surgery etc.
So my choice seems to be to switch to EE or lose my landline. I haven't yet checked out the costs. My Plusnet bill is going up by £3 next month.
What would you do?
