TL;DR
T-Mobile is running a limited buy-one-get-one promotion that can add a second line at no monthly charge after purchasing a new line. The deal surfaced on Reddit and PhoneArena and appears to require contacting T-Mobile support rather than finding it on the carrier's public website.
What happened
At the start of 2026, T-Mobile is offering a promotion that provides a free additional wireless line when a customer purchases a new line. The offer was reported by users on Reddit and highlighted by PhoneArena; it may not be visible on T-Mobile’s public site and often requires contacting the carrier directly by phone or chat to apply. Two promotion identifiers tied to the deal were shared by users: ID260060 and ID260164. The promotion is not universal across all legacy or current plans but has been confirmed to work with Go5G Plus and Next plans, and appears to be compatible with Experience Beyond and More plans as well. Customers taking advantage of the offer should confirm the full billing impact with a representative, since taxes and fees still apply and recent increases could affect the final amount on a bill. The report also notes internal employee dissatisfaction at T-Mobile, suggesting some behind-the-scenes friction.
Why it matters
- Potential immediate savings for customers who need an extra line, since the second line can be added without a monthly line charge.
- The deal may require extra effort to claim—representatives may need promotion IDs and the offer may not be listed online.
- Taxes and fees still apply to free lines, so total monthly costs may be higher than expected unless verified.
- Limited plan compatibility means not all customers will qualify; checking eligibility in advance can prevent billing surprises.
- Reports of employee dissatisfaction could affect in-store or support interactions for some customers.
