T-Mobile is offering a recurring promotion.
Another wave of free line offers hits T-Mobile customers.
T-Mobile is again offering a free line promotion to some subscribers. Many customers report receiving notifications about the offer, but the specific requirements for eligibility are not clear.
Currently, the offer appears to be available to subscribers on Family Choice and ONE plans. Other customers, including long-time subscribers, have not received the offer and have expressed frustration.
Some customers have commented on the situation.
One Reddit user, stylz168, posted in September 2025, “I haven’t gotten this offer at all. 25 years as a customer…”
Another Reddit user, Waste-Pay2775, posted in September 2025, “I never got a free line after 19 years with T-Mobile."
The terms and conditions appear to be a factor. For example, accounts with over two free or discounted lines are not eligible.
According to a Reddit user named Bwayan in September 2025, the offer is only valid if there are no more than two free or discounted lines on the account. They were told that they were ineligible because they had four active free lines.
Even if you are able to get the free line, it is not completely free. You will still have to pay taxes, the line is not eligible for a free phone or upgrade, and the free line could be canceled or converted to a paid line if a paid line is canceled within a year.
Subscribers should always read the fine print before agreeing to anything. Checking all the details can help you avoid surprises.
There are several benefits to adding a free line.
The most obvious advantage is a lower monthly payment. This can result in significant savings for families or groups sharing a plan. The additional line can also be used as a spare number for work, for a tablet or smartwatch, or for additional data.
T-Mobile benefits because customers are less likely to switch carriers when more lines are added to an account. Customers are more likely to remain locked in once multiple people are on the same plan.
This promotion is more of a customer retention strategy than a generous offer from T-Mobile. It can be a good way to save or get more flexibility if you qualify and understand the terms.
It is important to check the details before accepting the offer, but it is worth considering if it fits your needs. Free lines can help you get more out of your monthly plan, even though they do not include phones.
