Why can't I send emails on my BlackBerry Passport?

Just got a new Passport. I receive emails and texts and phone calls no problem, but I cannot return emails, texts or send new texts or emails.

Can anyone help, otherwise I'll have to change the phone, which I really do not want to do.

Thanks,
Brian

Hi Brian,

What do you mean exactly by can't?
Are you getting some sort of error message, are they not sending or are you having trouble finding out how to return a text or email?
