T-Mobile has launched a limited-time holiday promotion that lets customers get up to four free iPhones when switching carriers with four new lines. The offer targets families and groups who want to upgrade multiple devices without paying up front.
The carrier covers the full cost of the phones through monthly bill credits, provided customers keep all lines active for the full term.
How the deal works
T-Mobile includes four new iPhones with four new lines on a qualifying Essentials plan. Instead of an upfront discount, the carrier applies 24 monthly bill credits that offset the entire retail price over two years.
Customers still pay applicable taxes and a device connection fee per phone, but the deal does not require any trade-ins.
Steps to get the free iPhones
Customers need to follow a specific setup process to qualify for the credits:
- Switch to T-Mobile and open four new lines on a qualifying Essentials plan.
- Choose four eligible iPhone models at signup, either online or in-store.
- Port existing phone numbers from another carrier or activate new numbers.
- Enable AutoPay on the account to receive the advertised monthly pricing.
- Keep all four lines active for 24 months to receive the full bill credits.
If a customer cancels a line or leaves early, T-Mobile charges the remaining phone balance.
Monthly plan cost and conditions
The Essentials four-line plan costs about $100 per month total, before taxes and fees, with AutoPay enabled. Credits apply monthly, so customers need to maintain the account in good standing to keep the phones effectively free.
No trade-in required
This promotion skips the usual trade-in requirement. Customers can keep their old phones or sell them independently and still qualify for the credits, which simplifies the switching process.
Other devices included in holiday promos
T-Mobile also runs similar holiday deals on select Samsung Galaxy phones and other devices. Some offers include accessory discounts or bundled connected devices, depending on availability.
Why the offer stands out
Most carrier deals rely on trade-ins or single-device discounts. This promotion removes that friction by covering multiple iPhones at once with no trade-in requirement. For families already planning to switch carriers, the savings can add up quickly if they stay through the full credit period.
The offer remains time-limited, and T-Mobile may change or end it as the holiday sales window closes.
