I saw this deal yesterday https://slickdeals.net/f/14899711-t-mobile-free-add-a-line-aal-starting-3-17-march-madness-20-hookup-for-targeted-home-internet-connected-devices-customers?src=frontpage
Since I couldn’t use Google Voice, luckily I still had my Visible line that I had stopped paying back in January or so. I thought my number was cancelled, but I was able to log in and request a port out. They then emailed me the details.
Later in the afternoon I went into the Tmo store and asked if the promos could be stacked and the re said yes. So T-Mobile is giving out a non commitment free line. Then if you port over a line, you get the iPhone SE for free. I had to pay like $70 in taxes and fees but it’ll be worth it.
Not sure when deal ends but I wouldn’t wait till Monday. Offer is also only good once per account.
I’ve had 5 lines like this since mid 2020 all stacked with free phones. I also got them to add grandfathered Kickback to all the new lines (told the rep I have it on my primary line). So now each new line that’s not used which is all of them nets me a $10 discount. Essentially T-Mobile is paying me $10 a month for not using that free line.
