T-Mobile Free Voice Line OfferSimilar to a deal Sprint customers are getting, T-Mobile is offering new and existing customers a free voice line! The deal will go live starting on March 17, 2021 in stores and online. You can also call 1-800-937-8997 or text 611 and reference “2021 Line On Us P6”.
That's right, T-Mobile ONE now includes all monthly taxes, surcharges and fees. So, when a family of four signs up to pay $40 each with autopay for the unlimited T-Mobile ONE, they actually pay just that for unlimited wireless service—$40 per person and not a penny more.
How many lines can you add on T-Mobile? You can have up to 12 voice lines and 20 mobile internet lines on a regular Magenta or Magenta MAX customer account, Essentials plans may have up to six voice lines. Customers may be subject to a deposit depending on their credit and the number of lines they want to add.
Aside from T-Mobile Tuesdays and the same amount of data, talk, and text, Essentials customers don't get any of the other perks that T-Mobile One customers get. That means no international data (except in Canada and Mexico where 2G data is free), no free Netflix, and no in-flight Wi-Fi and texting.

The T-Mobile Magenta plan has unlimited data and unlimited mobile hotspot, making it a great plan for big data users.
First thing's first, the name "T-Mobile ONE" is out. Starting June 2, it'll be replaced by "Magenta." Magenta is mostly the same as T-Mobile ONE, offering unlimited talk, text, LTE data, free international texting + 2G data, access to T-Mobile Tuesdays, and one hour of free in-flight Wi-Fi on Gogo-enabled planes.
