T-Mobile has a deal if you already have 1 line and are looking at add 2 more lines. You can switch to the Magenta Plus plan and when you add the 2nd line, you get the 3rd line for free. Total for service is $140 for the 3 lines. This includes 2 screen HD Netflix. You can also combine this deal with a bogo iPhone deal. You can get the iPhone XR for $750 and get a free iPhone XR for the 3rd line. I suggest upgrading to the 128 GB for $50 more per phone.
