I know with my IPhone I have to have 2 different logins. One for in my house where I access it directly through the wireless network in my house using wifi. And then when I am using 3G I have to use my dyndns name. Why don't you try getting a dyndns domain name and try using it. Also with telus I found that I could not ise the default port 80 for the emails and texts.
