Is it okay to unplug my phone?

[#1]

I have had it 2 days and the cold calling has started -.- So is it okay to unplug it?

[#2]

yes

[#3]

Excellent. I don't use it for anything anyway

In case you ever need your landline phone, you could register with:
http://www.tpsonline.org.uk/tps/index.html
and also go ex-directory.

and that has absolutely no effect (tps that is)

Keep hold of the handset - if you ever have problems with the broadband you may need to plug it in to check if the phone is working OK.

I triedto register with tps but it says my number is already registered 
I will leave it unplugged

Well, it cut my unwanted calls substantially.

I still get loads and I have had it for ages
Used to be - free insulation
Then PPP claims
and of course all the ones from Microsoft and International Unavailable

Its also worth opting out of the 'Open' electoral register - https://www.gov.uk/electoral-register/opt-out-of-the-open-register

I used to get shed-loads of unwanted calls, but after ignoring any call where I didn't recognise the number (or it was unavailable/witheld), the incidence has dropped to 3 or 4 a week. Don't know if that's the reason, but I am happy.  
As a side-note, my 2 mobile numbers have had about half-a-dozen spam calls/texts between them, and I've had my Vodafone number for longer than I care to remember.
