And I've answered my own question about additional charges see
here. But still unsure about 0800 numbers - I assume these do not count as 'landline' numbers so are charged at 10p per minute all the time?
Also, incase anyone misses it - check out Note 5 down the bottom - not all 0870 numbers are the same now - another good reason to use
Say No to 0870!
