Greetings, I am considering purchasing a Android Phone on T-Mobiles monthly unlimited 4g. There exists some information from years ago about T-Mobile blocking tethering. Most of the information I was able to find was old and speculatory. My question is, This year of 2013 on 4g network. Does T-Mobile still block tethering? If so, What methods do they employ? Is it just common ports such as 80, 22, etc. Or do they have all Ports on the tethered PC blocked? I thank anyone for any effort made to respond.
