"Your listening port is blocked because of the reasons I mentioned previously. You don't have a full internet connection so you'll never get good results from torrents unless you can get them to give you a dedicated port to use, or get a different internet connection. \nThis won't prevent you from uploading, but anyone who wants you to send them data will get no reply from you because their connection is blocked by your ISP. If you connect to them first, then they request data, you'll be able to upload. \nOne less then optimal solution is to use NAT Traversal (available in bitcomet version 1.02 and some prior versions). It will enable you to get some remote connections, but is far from a solution to the problem. \nThe only real solution would be to get a different internet provider, however as far as I know, all cellular connections have this problem. \n"
