Since I got my 3G USB connector last week I am using it every day while driving to and from work. So far the experience has been great, but there is one small annoyance: China Telecom sometimes serves up ads for its 3G service while you’re surfing. Not sure what triggers it and I certainly don’t see what the use is. I am already using 3G so why bother to tell me I should use it? It happened to me twice so far when I click a link, the page then redirects to another one owned by Shanghai Telecom. When I go back and click the link again the ad does not reappear and the requested page loads. Very strange, I cannot explain why this happens.
