T-Mobile is offering the newly released Samsung Galaxy A17 5G for free when you add a new line with most unlimited plans. The deal requires no trade-in, applying enough promo credits over 24 months to zero out the phone's $229.99 price. You'll still pay a $35 activation fee and taxes, but the handset itself costs nothing.

The offer works on the carrier's entry-level Essentials plan, alongside the more expensive Experience More and Experience Beyond plans. This budget phone features a 6.7-inch AMOLED display, a 5,000mAh battery, and a rare six-year software support promise. It's a straightforward way to get a reliable Samsung device without a high upfront cost.

This promotion is a classic carrier move to lock in subscribers with a low-cost incentive. For consumers, it makes a solid mid-range phone essentially free with a new plan. Watch for similar deals as carriers compete for subscribers ahead of the next flagship season, with other free phone offers already available for the Samsung Galaxy S25 and Google Pixel 10 Pro.
