It will be December 2021 before you can port out any lines. Just to be safe, wait till January 2022. Then port the paid line to google voice for 3 months in January 2022.

Then April 2022, port from google voice back into tmobile free line.
So, I have a total of 6 lines on Magenta Plus and I'm paying for only two (4 lines are free). My parents are on the 55+ plan and so they will port out for three months and then take up 2 out of the 4 free lines. Would I be able to port my line (currently one I am paying for) and port back in after 3 months? Would I only be paying for one line out of 5?

Or for these free lines to stay active, will I always have to pay for two lines?

My bill generates this morning with extra charge of $30 as I see under my account. After I added a new line on 12/22, the system removed LOU 3, which caused $30 bill increase. This is headache.
Update:
Called in and rep was nice to make adjustment of $30 credit. And they are trying to fix it. Hopefully will get an update tomorrow.

Then you should see something like this:
Applied discounts and promotions:

No, you can only get 1 free line this week. Wait for another promotion in 2021 to get another line.

This worked for me. I didnt see a change in the amount of 2020 Line on Us 3 until I did this trick. I didnt get a text like the other person did but did see the amount change for that promo to account for the new line change.
