I had a phoneline from BT and they gave me free evening & weekend calls. I would rather have paid for what I used (especially now I use email so much) but they took that option away.
Then my daughter told me about 18185. If you register and dial 18185 in front of the number you are dialing it is much cheaper. For normal calls 5p/call 0p/min. Mobile calls are cheaper too. So I used that for weekday calls.
I've changed my phone to Plusnet, the same as my email. I looked on the 18185 website and it says I can still use it. But I am confused. There seems to be no way you can Contact them to ask a question other than links to pages of website. There it say you can dial a freephone no for your international calls. It gives a chart of prices for UK & International calls but doesn't say if you dial the same freephone no, or still use 18185 for UK calls
