T-Mobile: 4 Phones + Plans $100 per Month

New T-Mobile customers who switch and port in their existing number can get an iPhone 16 for free. If you add four devices with four new lines, you can stack the Essentials 4-Line Offer, which drops the price of the Essentials unlimited plan from $120 to $100 per month with auto-pay. That means you'll pay just $100 per month for four iPhones and four unlimited plans! This is one of the best deals we've seen for four phones with T-Mobile, and with access to freebies and exclusive offers through T-Mobile Tuesdays, it's one of the best deals available from any major carrier.
