T-Mobile released new Magenta Plans and are offering a great deal for new subscribers. Right now you can get Magenta Plus 3 lines for pretty much the same price as Magenta if you are a new customer or a single line customer. If you are a current T-Mobile multiline subscriber, unfortunately, you can’t take advantage of the 3rd line free deal so Magenta Plus is about $10 month more per a line.
T-Mobile Magenta is not all that different from T-Mobile One. Both include unlimited high-speed data on your phone but the main benefit I see is you now get 3 GB LTE mobile hotspot. They also dropped the included Netflix subscription to SD with 1 Screen. If you upgrade to Magenta Plus you will get 20 GB of Mobile Hotspot plus HD Netflix with 2 Screens as well as a few other great benefits such as Name ID and Unlimited gogo Inflight Wifi.
