I have been using TTN for a year now. The service was good in 2013. Lately I have been facing a lot of issues like:
1) Poor Speed(I have a 10 mb/ps connection. some times FB will not open)
2) Frequent Drop of connection
3) Foremost . No body responds on the helpline . I am trying for a week now .
TTN is not same as it startedbefore, will try some other service.
