T-Mobile makes changes to some grandfathered promos


It’s common practice for plans to lose some features and promotions when they get grandfathered. This is why there are those who are hesitant to change their plan once they know their existing plan will be discontinued by their carrier. For this same reason, T-Mobile has made some changes to the way they discontinue their old plans. 

This was initially shared on a Reddit post and was confirmed by The T-Mo Report. According to the report, T-Mobile’s free line promos and insider hookup promotions that they offered in the past can now be transferred to a newer plan when you decide to migrate.

The report also shared some internal documents that reveal details about the offer. One of these is for customers who migrate to a Magenta, Magenta MAX, or T-Mobile for Business 13+ rate plan. The good news is that T-Mo will now allow subscribers to keep their free line.

The report also confirmed that Insider Hookups from previous years will migrate too. Support can occasionally add a newer version of the 20% off to the new plan. 

If you are interested to learn more about this announcement, you can get in touch with T-Mobile support to confirm if your free line will transfer too.

    This is true I just transfer all my lines and keep my promos but I was told only on magenta max plan I can keep promos

    • dave

      Incorrect according to the other customers in this article and what I read online but does it really matter they’re going to give you one way or the other.p

      • Guillermo Eduardo Ortega-ibarr

        Base on my experience I was avail to keep all my 2 free lines as well as my 50% off on 1 only think I lost was kick back wish I never hit

    • The Waz

      I would double and triple check…Im speaking with the Executive Team and what Tforce was telling me is not accurate…i ended up canceling my migration

      • Guillermo Eduardo Ortega-ibarr

        Well it happen to me with no problem

  • vedichymn

    I was able to jump to Magenta Max and keep my insider discount and free lines through Tforce. Did lose kickback, but otherwise good.

    • dave

      Why would you change if I may ask?

  • The Waz

    They are giving me mixed information, sounds like they don’t even know

      Try Twitter or Facebook messenger you get the best help

  • Wait so, I have 5 lines on Simple Choice with 2gb of data for $113, I don’t really need the 5th line and would rather have 4 Unlimited lines. Am I able to take 4 of my lines to Magenta and have 4 Unlimited lines on Magenta for $120 once this promo starts?

    • TheTruthIsOutThere

      Strange. All 7 of my Simple Choice lines were automatically upgraded to 4GB of data… It is rare for a line to go over 1GB considering everyone is near wifi most of the time.

  • I’m on the all-in promo for $80 ($100 before 20% discount). I have two paid lines and one free. I can transfer this over and only pay for two lines (still have the third free), get my 20% off, not pay the taxes/fees, and get the perks of Magenta Max? Are we also eligible for future free lines or Bogo lines when they do that in the future?

    • Sharti24

      Im on the same exact plan as you. Im gonna call and ask to switch over to magenta max and see if that changes my bill at all.

      I know we are not eligible for free lines or to add lines in the future for that plan.

      • Sharti24

        I just called 611 and talked to an expert named “Corey”. He said he has not heard about any free upgrades and I was the first person who mentioned it to him

        • Guillermo Eduardo Ortega-ibarr

          Do tmobie Twitter or Facebook best help

      • Andrew Dunn

        If you find out let me know. I’d be interested to know if we can take advantage of free line promotions on magenta max if we switch over

  • dave

    Called tonight no one know about this at t mobile lol I’m sure they’ll find out in a day or two. 16 year customer if it matters… Thank you for the $1 coupon to Dunkin’ donuts on Tuesday that makes up for all the aggravation of being on hold for an hour and a half.

    • Sharti24

      Lol DD started at $2 now it’s down to $1. Next tmobile will shutdown TM Tuesday’s because too many people are taking advantage of it. Ie free pizzas

  • Gerald Mark

    I have the best discount you could ever ask for outside of military/1st responder honestly.
    9 lines: $240
    Except its with the benefits of Magenta Max. That’s normally $355. But I don’t get any of the amazing trade in promos magenta max customers get. I’m on T-Mobile One with One Plus for free on all lines and one free line ($30 off)

    • Austin8480

      I am still on a Simple Choice plan that originally gave us unlimited talk, text and 6GB or data. All lines have now been upgraded to unlimited talk, text and data, and I now get 6GB for hotspot. I have a total of 7 phone lines and 2 wearables for $200. I do receive a discount of 15% for my job. I haven’t been eligible for any trade in promos and I am ok with that. For me to move to a different plan with all the goodies would raise my bill to over $300.

    • dcmanryan

      I have 9 lines and at $126 before kickback kicks in and I know many with a way better deal than me. I have T-Mobile One with the One Plus Promo and the 20% off Hookup code applied. You have a decent deal but far from the best. 3 lines free I should add too.

      ONE Plan $126.00/mo
      Applied discounts and promotions:
      $40 AutoPay Discount
      $54 Insider Discount
      $30 2020 Line On Us
      $30 2020 Line On Us 2
      $30 2021 Line on Us 6
