I contacted T-Mobile because I haven’t seen the discount for the free line from the t-life app yet and while trying to talk to a rep this free line offer popped up.

According to an AI-generated response to their query, a free line offer is available to subscribers on Go5G Plus and Go5G Next plans. Customers who add a new line can get up to $1,000 in bill credits applied over 24 months.
The promo doesn’t include the financing of a new phone, like the T Life offer.
No discounted phones are not supported with this free line unfortunately

T-Mobile is apparently also sending out texts to customers who qualify for the promo and it appears to be those who weren’t eligible for the T Life offer.
While it’s generous of T-Mobile to give away a free line, some customers aren’t impressed and would rather that the company not raise prices. Others are wondering if there’s any fine print here and whether the line will cease to be free after two years. T-Mobile‘s AI-powered chat system says customers will have to pay for the line after 24 months, meaning this isn’t a free-for-life promo.
I asked if what happens after the 24 months and the chat feature said we would be responsible for paying the line.

That said, even 24 months’ worth of savings in the form of a free line is not bad. If the offer interests you and you haven’t received a text about it yet, you might want to get in touch with support to see if you qualify.
