An unlocked iPhone gives you the freedom to pick any carrier, but only if it is the right version of the phone. This guide lists the model number for every iPhone Apple still supports, from the iPhone 11 to the new foldable iPhone Duo, shows which versions are built for US carriers and which are eSIM-only, compares the network bands Verizon, AT&T, and T-Mobile use with the bands each iPhone supports, and explains how to confirm an unlocked iPhone will work on your network before you buy. A model-by-model rundown follows with each US model’s LTE and 5G bands and what each iPhone sells for on Swappa, plus the iPhone 8 through iPhone XS for anyone shopping older models.
Quick Answer
A factory unlocked, US-model iPhone from the iPhone 11 onward works on Verizon, AT&T, T-Mobile, and their prepaid brands, as long as it has a clean IMEI and no Activation Lock. Check the model number (the “A” number) against the table below: each iPhone has a US version, and most international versions lack T-Mobile’s 600 MHz band 71 and AT&T’s band 14. US models from the iPhone XR on support every LTE band the three major carriers use, and US models from the iPhone 12 on support all of their 5G bands. US iPhones from the iPhone 14 on have no SIM tray, so your carrier must support eSIM. Shop unlocked iPhones on Swappa.
What Unlocked Means for an iPhone
A carrier-locked iPhone only works with the carrier that sold it until that carrier removes the lock. An unlocked iPhone accepts service from any compatible carrier. There are three versions you will run into:
- Factory unlocked: sold by Apple without a carrier lock. On Swappa, only factory unlocked devices go in the Unlocked category.
- Carrier unlocked: bought from a carrier and unlocked later. It works like an unlocked phone, but Swappa lists it under the original carrier so buyers know its history.
- Unlocked Non-US: phones sold outside the US. Swappa lists them separately because they may not support everything your carrier uses.
Watch for one more label: a Flex (or “SIM OUT”) device is not factory unlocked. It locks to the first US carrier it connects to, which the US Reseller Flex Policy explains.
If a carrier iPhone is still locked, it works only on that carrier. Unlocked vs. Carrier-Locked Phones: What It Means When Buying Used covers how unlocking works and when it matters.
How to Find an iPhone’s Model Number
Every iPhone has a model number that starts with “A,” and it tells you which regional version you have.
- Open Settings > General > About.
- Find Model Number. It first shows a part number (for example, one ending in LL/A).
- Tap it once to reveal the model number that starts with “A.”
Then match it to the table below. When you are buying, ask the seller for the A-number in a listing comment if it is not in the description.
The same About screen also shows whether the phone is unlocked. Look for Carrier Lock: it reads “No SIM restrictions” on an unlocked iPhone. Ask the seller for a screenshot of that line along with the model number.
Unlocked iPhone Model Numbers: iPhone 11 to iPhone Duo
This table covers every iPhone that runs iOS 27. The US model is the version built for US carriers. Versions in the Canada, Japan, and Mexico column support nearly every US band, while the China and other-countries versions miss several, as the band sections below explain. Each model name links to its unlocked listings on Swappa.

Source: Apple’s Identify your iPhone model page, checked October 7, 2026. The iPhone Duo goes on sale October 23, 2026, and is not on that page yet, so its numbers come from Apple’s iPhone Duo tech specs and the matching Canada, UK, and China spec pages. Apple’s regional groupings vary by model. For example, the iPhone 13 through iPhone 15 “Canada and Japan” versions also cover Mexico and Saudi Arabia, and some China versions also cover Hong Kong and Macao. For the iPhone 13, iPhone 14, and iPhone SE (3rd gen), Apple also lists a separate model for Russia and nearby countries.
eSIM-Only iPhones: What Buyers Need to Know
Starting with the iPhone 14, Apple stopped putting a SIM tray in US iPhones. Every US iPhone 14, 15, and 16, the iPhone 16e, the entire iPhone 17 and iPhone 18 Pro lineups, and the iPhone Duo are eSIM-only. The iPhone Air and the iPhone Duo have no SIM tray in any country, and the iPhone 17 series, iPhone 17e, and iPhone 18 Pro models also skip the tray in Canada, Japan, Mexico, and several other countries.
For buyers, that means:
- Your carrier must support eSIM. All three major US carriers do, and so do most prepaid brands, but check before you buy if you use a smaller carrier.
- Activation happens in software. You transfer your number from your old iPhone during setup or through your carrier’s app or website instead of moving a physical card.
- A SIM tray can reveal an international model. If an iPhone 14 or newer has a physical SIM tray, it is not a US model. The reverse does not hold: an iPhone Air or iPhone Duo has no tray anywhere, so check its model number instead.

US Carrier Network Bands in 2026
A network band is a slice of radio spectrum. To get full coverage, an iPhone has to support the bands your carrier uses where you live and work. These are the main 4G LTE and 5G bands the three major US carriers run in 2026.
US carrier 4G LTE bands
| Carrier | LTE bands | Low-band coverage bands |
|---|---|---|
| Verizon | 2, 4, 5, 13, 66 | 13 (700 MHz) and 5 (850 MHz) |
| AT&T | 2, 4, 5, 12, 14, 17, 29, 30, 66 | 12, 14, 17, and 29 (700 MHz) and 5 (850 MHz) |
| T-Mobile | 2, 4, 12, 66, 71 | 71 (600 MHz) and 12 (700 MHz) |
Low-band spectrum travels the farthest and reaches deepest inside buildings, so these are the bands that matter most in rural areas. Band 13 is Verizon’s main coverage band, band 14 is the 700 MHz band AT&T built for the FirstNet public safety network and also uses for regular customers, and band 71 is T-Mobile’s 600 MHz layer.
US carrier 5G bands
| Carrier | Low-band | Mid-band | mmWave |
|---|---|---|---|
| Verizon | n5 | n2, n66, n77 (C-band) | n260, n261 |
| AT&T | n5 | n2, n66, n77 (C-band and 3.45 GHz) | n260 |
| T-Mobile | n71 | n25, n41 | n260, n261 |
Mid-band carries most of the fast 5G. Verizon sells its n77 C-band service as 5G Ultra Wideband, AT&T calls its n77 and mmWave service 5G+, and T-Mobile’s n41 network is its Ultra Capacity 5G. mmWave is the fastest of all but covers very little ground, mostly stadiums, arenas, and a few dense downtown areas.
AT&T closed its roughly $23 billion purchase of EchoStar’s 3.45 GHz and 600 MHz licenses on July 28, 2026. The 3.45 GHz spectrum already carries AT&T 5G on band n77. AT&T has said the 600 MHz spectrum will take years to put into service because it needs new equipment for it. When it does arrive, that spectrum uses bands 71 and n71, which US iPhones already support (band 71 since the iPhone XR, n71 since the iPhone 12).
Prepaid brands run on these same networks and use the same bands: Visible and Total Wireless on Verizon, Cricket on AT&T, and Metro by T-Mobile and Mint Mobile on T-Mobile.
Which iPhones support the US carrier bands
- US models from the iPhone XR on support every LTE band in the tables above, including Verizon’s band 13, AT&T’s band 14, and T-Mobile’s band 71.
- US models from the iPhone 12 on also support every 5G band above, including n77, n71, n41, and n25. All of them have mmWave except the iPhone SE (3rd gen), iPhone 16e, iPhone Air, and iPhone 17e, which skip mmWave in every version.
- The iPhone 11 series, iPhone SE (2nd gen), iPhone XR, and iPhone XS models are 4G LTE only, with no 5G.
- Every version of the iPhone 8, 8 Plus, and X lacks LTE bands 14 and 71. They miss T-Mobile’s 600 MHz layer and AT&T’s FirstNet band, which can mean weaker signal in rural areas and indoors on those two networks.
Apple also lists 3G (UMTS) and 2G (GSM) support for each iPhone. Those only matter abroad now that every US carrier has shut its 3G and 2G networks down, so the band lists in this guide leave them out. Carriers add and move spectrum over time, so your carrier’s BYOD checker has the final word on a specific phone.
US vs. International iPhones on US Carriers
A US-model iPhone is the safest choice for a US carrier, because it was designed and certified for US networks. International versions often work, but not always completely. They can miss some of the frequency bands a specific carrier relies on, lack features built for US networks, or behave differently with carrier services, and a few carriers restrict devices that were not sold in the US.
Apple’s band lists show a consistent pattern in what each group of non-US versions is missing compared with the US model:
| Version | Example model numbers | Missing US carrier bands |
|---|---|---|
| Canada, Japan, and Mexico versions, iPhone 12 to iPhone Duo | A3519 (iPhone 17), A3089 (iPhone 15), A2631 (iPhone 13) | mmWave only |
| Versions for other countries, China, and Russia, iPhone 12 to iPhone Duo | A3520 (iPhone 17), A3090 (iPhone 15), A2633 (iPhone 13) | LTE bands 14, 29, and 71, 5G band n71, and mmWave |
| Japan versions of the iPhone Air and iPhone SE (3rd gen) | A3516, A2782 | LTE bands 14, 29, and 71 and 5G band n71 |
| International iPhone 11, 11 Pro, 11 Pro Max, and SE (2nd gen) | A2221, A2215, A2218, A2296 | LTE bands 14 and 71 |
| International iPhone XR, XS, and XS Max | A2105, A2097, A2101 | LTE band 71 |
Here is what those gaps mean on each network:
- T-Mobile: without band 71 and n71, an international iPhone loses T-Mobile’s 600 MHz layer, the signal that reaches farthest in rural areas and deepest inside buildings. It still works on T-Mobile’s other LTE bands and on n41 and n25 5G, but coverage can drop where 600 MHz is the only signal.
- AT&T: without band 14, it loses AT&T’s FirstNet 700 MHz band, and band 29 is an extra download-only band. Bands 2, 4, 5, 12, 17, 30, and 66 remain, so the phone usually works, with less capacity in busy areas.
- Verizon: international versions keep band 13 and n77, so bands are rarely the problem on Verizon. The bigger question is whether Verizon will activate an imported device, which its BYOD checker answers.

On Swappa, those phones sit in the Unlocked Non-US category, and it is up to you to confirm with your carrier first. The reliable way to do that is to run the phone’s IMEI through your carrier’s BYOD (bring your own device) checker. Will This Used Phone Work on My Carrier? explains how bands and BYOD checks work.
CDMA Is Gone: Why Old GSM vs. CDMA Advice No Longer Applies
Older compatibility guides, including earlier versions of this one, spent a lot of time on GSM and CDMA versions of the same iPhone. That no longer matters. AT&T, T-Mobile (including the former Sprint network), and Verizon all shut down their 3G and CDMA networks in 2022, and every US carrier now runs on 4G LTE and 5G with voice over LTE (VoLTE). What matters now is LTE and 5G band support, covered above.
Every iPhone in the table above supports VoLTE and works on modern US networks. The iPhone XS, XR, X, 8, and earlier have also stopped getting new iOS versions, so most buyers are better off with a supported model.

- TD-LTE: 34, 38, 39, 40, 41, 42, 46, 48

Older iPhones: iPhone 8 to iPhone XS Max
These iPhones still work on US carriers’ LTE networks with VoLTE, but none of them can run iOS 26 or iOS 27. The iPhone XR, XS, and XS Max stopped at iOS 18, and the iPhone 8, 8 Plus, and X stopped at iOS 16. That means fewer app updates over time and no new features, so treat them as backup phones or a first phone for a kid, and run the IMEI through your carrier’s BYOD checker before you buy. Each one has a nano-SIM tray, and the XR, XS, and XS Max also support eSIM. None of them has 5G. The US XR, XS, and XS Max support every LTE band the major carriers use, while every version of the iPhone 8, 8 Plus, and X lacks band 14 and band 71.
iPhone XR
The iPhone XR for US carriers is model A1984. The A2105 is the global version, and it lacks LTE band 71, T-Mobile’s 600 MHz layer, so confirm it with your carrier’s BYOD checker before you buy. A 64GB iPhone XR averaged $109 on Swappa. Shop unlocked iPhone XR listings or check iPhone XR prices.
iPhone XR network bands (US model A1984):
- FDD-LTE: 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 29, 30, 32, 66, 71
- TD-LTE: 34, 38, 39, 40, 41
iPhone XS
Apple sold one iPhone XS model for every US carrier: A1920. The A2097 is the global model for Europe and Asia, and it lacks LTE band 71. A 64GB iPhone XS averaged $133 on Swappa. Shop unlocked iPhone XS listings or check iPhone XS prices.
iPhone XS network bands (US model A1920):
- FDD-LTE: 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 29, 30, 32, 66, 71
- TD-LTE: 34, 38, 39, 40, 41, 46
iPhone XS Max
The iPhone XS Max for US carriers is model A1921. The A2101 is the global model, and it lacks LTE band 71. A 64GB iPhone XS Max averaged $158 on Swappa. Shop unlocked iPhone XS Max listings or check iPhone XS Max prices.

- TD-LTE: 34, 38, 39, 40, 41, 46
iPhone X
Apple sold two iPhone X models in the US. The A1865 was the Verizon, Sprint, and SIM-free version, and the A1901 was the AT&T and T-Mobile version. With CDMA gone, the old reason to prefer the A1865 no longer applies: Apple lists the same LTE bands for both, and neither supports band 14 or band 71. Confirm either one with your carrier’s BYOD checker. A 64GB iPhone X averaged $118 on Swappa. Shop unlocked iPhone X listings or check iPhone X prices.
iPhone X network bands (A1865 and A1901):
- FDD-LTE: 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 28, 29, 30, 66
- TD-LTE: 34, 38, 39, 40, 41
iPhone 8
The iPhone 8 also came in two US versions: the A1863 (Verizon, Sprint, and SIM-free) and the A1905 (AT&T and T-Mobile). Apple lists the same LTE bands for both, without band 14 or band 71. A 64GB iPhone 8 averaged $67 on Swappa. Shop unlocked iPhone 8 listings or check iPhone 8 prices.

- TD-LTE: 34, 38, 39, 40, 41
iPhone 8 Plus
The iPhone 8 Plus came as the A1864 (Verizon, Sprint, and SIM-free) and the A1897 (AT&T and T-Mobile). Like the iPhone 8, both versions share the same LTE bands and lack band 14 and band 71. A 64GB iPhone 8 Plus averaged $87 on Swappa. Shop unlocked iPhone 8 Plus listings or check iPhone 8 Plus prices.
iPhone 8 Plus network bands (A1864 and A1897):

- TD-LTE: 34, 38, 39, 40, 41
How to Check an Unlocked iPhone Before You Buy
- Confirm the category. On Swappa, the Unlocked category is reserved for factory unlocked phones. A carrier phone that has been unlocked is listed under its original carrier.
- Check the model number against the table above, and ask the seller in a listing comment if it is not listed. Ask for the Carrier Lock line from the same About screen, too.
- Look for Unlocked Non-US labels if you specifically want a US model. Most non-US versions lack T-Mobile’s band 71 and AT&T’s band 14, so compare the model’s bands with your carrier’s in the tables above.
- Confirm eSIM support with your carrier if the phone is an iPhone 14 or newer.
- Run the IMEI after purchase. Sellers keep the IMEI private until the sale, and Swappa requires a clean IMEI on every listing. Once you have it, you can confirm with your carrier’s BYOD checker and Swappa’s free IMEI checker.
- Check for Activation Lock when the phone arrives. iCloud Activation Lock: How to Avoid It on a Used iPhone explains what to look for.
Carrier-Locked vs. Unlocked iPhones: Is Unlocked Worth Paying For?
Unlocked iPhones do not always cost more, so compare before you buy. Here is the average asking price of active 128GB iPhone 13 listings on Swappa on October 7, 2026:
| 128GB iPhone 13 | Average asking price on Swappa |
|---|---|
| Unlocked | $291 |
| AT&T | $265 |
| T-Mobile | $291 |
| Verizon | $326 |
Prices change daily and vary with condition, so check current iPhone 13 prices for the latest averages. If you are staying with AT&T, a phone listed under AT&T can save you around $25. If you might switch carriers, travel internationally with a local SIM, or resell later, a factory unlocked phone is worth paying a little extra for. It also holds its value better: Swappa’s trade-in quote for a 128GB iPhone 13 was $131 unlocked, compared with $96 to $109 for the carrier versions. And when a carrier listing costs more than an unlocked one, as Verizon does here, the unlocked phone is the easy pick.
FAQ
Will an unlocked iPhone work on Verizon?
Yes, if it is a US-model iPhone from the iPhone 11 or newer, it is truly unlocked, and it has a clean IMEI. US iPhone 14 and newer models activate on Verizon with eSIM. For an international model, run the IMEI through Verizon’s BYOD checker before you buy.
Do unlocked iPhones work on every carrier?
A factory unlocked US-model iPhone works on Verizon, AT&T, T-Mobile, and the prepaid brands that run on their networks. International models and carrier phones that were never unlocked may not, so check the model number and run the IMEI through your carrier’s BYOD tool.
What bands does an iPhone need for Verizon, AT&T, and T-Mobile?
Verizon’s key bands are LTE band 13 and 5G band n77. AT&T’s are LTE bands 2, 12, 14, 17, and 66 and 5G band n77. T-Mobile’s are LTE band 71 and 5G bands n71, n41, and n25. Every US-model iPhone from the iPhone XR on supports all of those LTE bands, and US models from the iPhone 12 on support all of those 5G bands.
Can I use a physical SIM card in a US iPhone 15?
No. US models of the iPhone 14 and every newer iPhone have no SIM tray and use eSIM only. If an iPhone 14 or newer has a SIM tray, it is an international version.
Are international iPhones worth buying in the US?
Sometimes, but they carry more risk. Most international versions lack LTE bands 14, 29, and 71 and 5G band n71, which weakens T-Mobile coverage in rural areas and indoors and trims AT&T capacity, and a few carriers restrict imported devices. Most Canada, Japan, and Mexico versions keep every US band except mmWave. Swappa lists these phones as Unlocked Non-US; confirm compatibility with your carrier before buying one.
Will the iPhone Duo work on my carrier?
The US iPhone Duo (model A3447) is built for US carriers and is eSIM-only, so your carrier needs to support eSIM. It goes on sale October 23, 2026. Before you buy a used one, confirm the A-number and check that Carrier Lock reads “No SIM restrictions.”
Does an unlocked iPhone XS or iPhone 8 still work in 2026?
Usually, yes. The US models of the iPhone 8, X, XR, XS, and XS Max support LTE and VoLTE, which US carriers now require. The iPhone 8, 8 Plus, and X lack LTE bands 14 and 71, so coverage on AT&T and T-Mobile can be weaker. None of them get new iOS versions, so run the IMEI through your carrier’s BYOD checker first and consider an iPhone 11 or newer if you want years of updates.
Which unlocked iPhone is the best value for all US carriers?
For most buyers, a factory unlocked US iPhone 13 is the best value. A 128GB iPhone 13 averaged $245 in sales on Swappa in early October 2026, and prices vary with condition. It works on every major US carrier, supports both a physical SIM and eSIM, and still runs iOS 27.
Conclusion
Carrier compatibility used to be complicated. For iPhones in 2026, it mostly comes down to three checks: a US model number, which brings every band your carrier uses on the iPhone XR and newer, a factory unlocked phone (or one unlocked from your carrier), and eSIM support on your plan. Match the A-number to the table, compare its bands with your carrier’s, confirm with your carrier’s BYOD tool, and you can buy with confidence.
