Buying an iPhone Duo? These are T-Mobile's deals to save big on Apple's first foldable

Pre-orders for the iPhone Duo begin tomorrow, and carriers are rolling out aggressive promotions to get Apple’s first foldable into users’ hands. We’ve seen competitors like AT&T and Xfinity Mobile roll out the red carpet with their iPhone Duo deals, and now, T-Mobile has announced its pre-order deals for the brand-new iPhone Duo, offering up to $1,000 off for consumer accounts and up to $1,400 off for business lines.

Customers on T-Mobile’s Experience Beyond or Go5G Next plans can secure up to $1,000 off the iPhone Duo (or any iPhone 18 Pro model). Notably, the full discount applies either via an eligible trade-in in any condition or, alternatively, without a trade-in when adding a new line and switching from another network.

T-Mobile is also offering financing over 36 months with a zero down payment at checkout via its EIP Flex 36 option, which covers device taxes and fees upfront for well-qualified buyers. Eligible plans continue to bundle carrier perks, including access to T-Mobile’s 5G Advanced network, T-Mobile Tuesdays rewards, discounted Apple TV ($3 per month), and free streaming subscriptions like Netflix, Hulu, and MLB.TV.

Business accounts on T-Mobile’s SuperMobile tier receive even steeper incentives:

• Switching with eligible trade-in: Up to $1,400 off the iPhone Duo (dropping financing payments down to $25 per month) or any iPhone 18 Pro model.
• Switching without trade-in: Up to $1,100 off when porting a line to SuperMobile.
• Existing line upgrades: Up to $1,200 off with an eligible trade-in in any condition.

Pre-orders for the iPhone Duo kick off tomorrow, October 16, with deliveries beginning October 23.

Beyond these deals, T-Mobile confirmed it will support Apple’s new iPhone Handoff feature on day one. The capability allows customers to assign a single mobile number to two compatible devices and seamlessly switch which handset serves as the active primary line.
