T-Mobile is offering two lines for the price of one in a new BOGO deal

Source: Android Authority

TL;DR

• T‑Mobile is offering you the chance to add one paid line and get a second for free.
• To qualify, you’ll need two existing paid lines in addition to the two lines added by the BOGO offer.
• You’ll need to select a mid‑range plan like Experience More and keep both the paid and free lines for at least a year.

Offer Overview

All three major carriers occasionally run special promotions for free lines, though Verizon and T‑Mobile do this more regularly than AT&T. T‑Mobile’s latest BOGO promotion lets users add one paid line and receive a second line for free.

The deal was first spotted on Reddit (source) and is aimed at families looking to add a child’s line.

Eligible Plans

• Go5G Plus
• Go5G Next
• Experience More
• Experience Beyond

These plans are all eligible, but a few additional caveats apply.

Eligibility Requirements

1. Existing Paid Lines – You must have at least two paid voice lines on your account before enrolling.
2. Duration – The two new lines (one paid, one free) must remain active for a full year from the enrollment date.
3. Restoration Window – If you lose the free‑line credit due to a plan change, you have 90 days to restore the line or plan.
4. Post‑Year Options – After the year ends, you can cancel the extra paid line and keep the free line indefinitely, provided you still maintain at least two paid accounts.
