Shirley, I use TalkTalk and found that I could use the Internet OK and this site etc… . But, my email programme would receive email but it would not let me SEND email. This is down to TalkTalk blocking you sending unless you use a TalkTalk line. I believe several other internet providers do the same. If you are technical person you could alter the SMPT setting but it is not something I would advise.
If you have a HOTMAIL account you are OK, you can send and receive. I have now set up Gmail (GOOGLE – hotmail). HOWEVER, I did it whilst in the ward and I cannot transfer my email addresses from TalkTalk to Gmail for the same reason as above, so I have to type in the email addresses to GMAIL that I want to use. So my tip is to set up your Hotmail account and transfer any email address BEFORE you go in if you think you might need it.
