T-Mobile has begun advertising a new promotion that offers the Apple iPhone 18 Pro "On Us" ahead of the official preorder launch. The offer is detailed on T-Mobile's website, with preorders scheduled to begin on September 12. The iPhone 18 Duo preorder date is October 16.

To qualify for the "On Us" deal, customers must either switch carriers and port in their number or trade in an eligible phone in any condition. Additionally, they must subscribe to the Experience Beyond plan. The discount will be applied as bill credits over a 36-month period, and a one-time $35 connection charge applies. The Experience Beyond plan is priced at $100 per month for a single line with AutoPay, offering unlimited talk, text, and premium 5G data. This plan also includes subscriptions to Netflix (Standard with ads) and Hulu, Apple TV for $3 per month, unlimited mobile hotspot, T-Satellite, annual phone upgrade eligibility, and a five-year price guarantee. International perks include unlimited text and 30GB of high-speed data in Canada and Mexico, as well as 15GB of high-speed data in over 215 other countries.

Currently, the promotion explicitly mentions the iPhone 18 Pro. However, it is anticipated that similar discounts may be extended to the iPhone 18 Pro Max and the iPhone Duo, which is expected to retail for $1,999. This foldable device will feature dual displays: a 5.4-inch screen when closed and a 7.6-inch screen when unfolded, making it Apple's thinnest iPhone to date in its unfolded state. Both the Pro and Pro Max models are equipped with the new Apple A20 Pro processor, built on a 2-nanometer process, promising a 40% increase in graphics performance over previous generations. Notable camera upgrades include a main sensor with variable aperture (f/1.48 to f/4.0) and faster 60W charging. The iPhone Duo will also feature the A20 Pro processor.

This offer allows customers to acquire the latest iPhone model without the significant upfront cost, provided they plan to remain on T-Mobile's network and utilize their 5G service.
