Xfinity Mobile iPhone Duo deals

Checked Nov 4, 2026. Offers below are as of Nov 4, 2026, from Xfinity's own pages unless a dated report is named, and Xfinity changes deals often.

Xfinity Mobile opened iPhone Duo pre-orders on Friday, Oct 16 and started availability on Friday, Oct 23, per Comcast's Sept 9 announcement. As of Nov 4, 2026, Xfinity's iPhone Duo page lists the phone on backorder with an estimated shipment date of Dec 3, 2026. The catch comes first: Xfinity Mobile is a perk for Xfinity Internet customers, not a standalone carrier.

The iPhone Duo offer

As of Nov 4, 2026, Xfinity's Apple deals page advertises up to $1,000 off the iPhone Duo. Xfinity says that takes a new Mobile Plus line, a qualifying trade-in and a device payment plan, and adds that Xfinity Internet is required, with taxes and fees extra.

Who qualifies? Tom's Guide reported on Oct 8 that the offer covered new Xfinity Mobile Plus customers, existing Diamond members with Mobile Plus, and customers on legacy Premium Unlimited plans. Xfinity's iPhone Duo page also lists $400 off a new Mobile Plus line with no trade-in, as of Nov 4, 2026.

The discount arrives slowly. Xfinity's offer details say the credits come off your bill monthly over a 36-month device payment agreement. Existing Mobile Plus customers who upgrade can get up to $1,000 off with a trade-in only if they're Diamond members; other upgraders get up to $500 off with a trade-in or $200 off without one, and the current phone must be fully paid off.

Xfinity's Apple deals page doesn't spell out which trade-ins earn the full $1,000, so check the value Xfinity quotes for your phone before you commit. Xfinity's fine print says the trade-in must be completed within 21 days of the ship date and that its value varies and can't exceed the phone's retail price.

One date to watch: Xfinity's offer details for the iPhone Duo say the $1,000 offer ends Nov 10, 2026, and that out-of-stock phones aren't eligible, which matters because the Duo is on backorder as of Nov 4, 2026. Before you order, confirm at checkout that the offer applies to your order.

Price and financing

As of Nov 4, 2026, Apple's US prices are $1,999 for 256GB, $2,199 for 512GB, $2,599 for 1TB and $3,199 for 2TB, per MacRumors. Xfinity lists the 256GB iPhone Duo at $1,999.99, or $55.55 a month for 36 months at 0% APR before promotions ($61.11 for 512GB, $72.22 for 1TB, $88.88 for 2TB), and its product page says the estimate may require a down payment.

With the $1,000 trade-in estimate, Xfinity's page shows the 256GB model at $27.77 a month for 36 months, after a $27.77 monthly promo device credit, with $0 down and device taxes extra. The Mobile Plus line costs $45 a month on top of that.

Xfinity Support says on its device payment plan FAQ that devices can be paid over 36 months, that eligibility depends on a soft credit check, and that taxes on the full device price are paid up front.

You need Xfinity Internet

Comcast's plan page is blunt: "All plans require an Xfinity Internet account at sign up." That rules out anyone outside Xfinity's home internet footprint, and it means the real comparison is your combined internet and phone bill.

What if you drop internet later? As of Nov 4, 2026, Xfinity's cancellation details page says customers on the latest plans can keep Xfinity Mobile, but lose the $10 Multi-Product Discount, which raises the monthly bill. Lines bought between March 22, 2024 and April 21, 2026 that haven't moved to the latest plans pay a $25 standalone mobile fee per account each month instead.

Plans: Mobile Plus and Mobile Select

If you remember Xfinity's Unlimited and By the Gig plans, those are gone for new customers. Comcast launched Mobile Plus and Mobile Select on April 22, 2026, and Phone Scoop reported that Mobile Select replaced Unlimited and Mobile Plus replaced Premium Unlimited. Xfinity's By the Gig support page says that plan is only for customers who joined before April 22, 2026.

As of Nov 4, 2026, Mobile Plus costs $45 a line per month, per Comcast, with unlimited premium data, 4K streaming, device upgrades for eligible customers and lifetime device protection against damage, loss and theft. Mobile Select costs $30 a line with 50GB of premium data and HD streaming. Both include Global Travel Pass for 215+ destinations and WiFi PowerBoost on Xfinity WiFi hotspots.

The iPhone Duo offer needs Mobile Plus, so Select's lower price doesn't help with the $1,000. Comcast also says qualifying Xfinity Internet customers can try a free line of Mobile Select for 12 months.

What happens if you leave or pay off early

Xfinity Support's device credits FAQ says that making extra payments to pay off the device ends your eligibility for device credits. It also says credits stop and are forfeited if the line is cancelled, whether you cancel it or it's shut off, and that upgrading to a new device stops credits on the current one.

That FAQ describes paying over 24 months, but the Duo offer's own fine print requires a 36-month device payment agreement and says remaining credits are forfeited if the Mobile Plus line isn't kept or payments are accelerated.

It runs on Verizon's network

Xfinity Mobile has used Verizon's network since its 2017 launch, under an MVNO deal Comcast signed years earlier, per RCR Wireless. Android Authority reported in April 2026 that both new plans run on Verizon's 5G network, with WiFi PowerBoost handling hotspot data. If Verizon coverage is weak where you live, Xfinity's coverage likely is too.

eSIM setup on Xfinity Mobile

The iPhone Duo doesn't take a physical SIM. Apple's spec page lists dual eSIM and says the phone isn't compatible with physical SIM cards.

Switching from Android is easier than it used to be. Apple's Android eSIM transfer document lists Xfinity Mobile among the supported US carriers, with iOS 26 or later on the iPhone and Android 16 or later on the Android phone, both on Wi-Fi with Bluetooth on.

Protection: Mobile Care Plus vs. AppleCare+

Mobile Plus includes Xfinity Mobile Care Plus at no extra cost, per Xfinity's protection plan page, which lists $0 screen-only repairs for smartphones. As of Nov 4, 2026, on other plans Xfinity Mobile Care costs $9 to $19 a month plus tax, depending on the device. Xfinity's page doesn't list the iPhone Duo's service fees or deductibles, so look them up for the Duo before you rely on it for an inner-display repair.

As of Nov 4, 2026, AppleCare+ for iPhone Duo is $329 upfront or $16.49 a month, and AppleCare+ with Theft and Loss is $399 upfront or $19.99 a month, per Apple's AppleCare+ terms. Xfinity's AppleCare+ support page says AppleCare+ bought through Xfinity is a one-time upfront charge for 24 months, offered only when you buy the device, and warns that adding it alongside Xfinity Mobile Care may duplicate coverage. Our AppleCare+ vs. carrier insurance guide covers the trade-offs.

Bottom line

The Xfinity Mobile iPhone Duo deal suits existing Xfinity Internet customers who were going to pay for an unlimited plan anyway, have a phone worth trading in, and plan to stay three years. At $45 a line as of Nov 4, 2026, Mobile Plus with protection included is a fair price on paper.

It's the wrong pick if you don't have Xfinity Internet, might move outside Comcast's area, or want to sell the Duo early. Buying unlocked costs more up front but keeps you free. Compare it with our Verizon, AT&T and T-Mobile guides, and where to buy. More on iPhone Duo deals.
