Buying an unlocked iPhone may sound confusing, but Swappa is here to help make that process as easy as possible. The following guide walks you through everything you need to know about buying a cheap iPhone, so you can be sure it’s compatible with your wireless carrier.

What is an unlocked iPhone?
This part trips up a lot of folks. The word “unlocked” can be used to describe anything from the lock screen to iCloud, so it’s best to define what the term “unlocked iPhone” actually means.
- Factory Unlocked Phones: The iPhone was originally sold unlocked and is typically compatible with most or all US carriers
- Carrier Unlocked Phones: The iPhone was originally locked to a specific carrier but has been unlocked to work on other compatible networks
- iCloud Unlocked Phones: The iPhone is ready for use by a new user, and the original owner hasn’t reported the phone as lost or stolen
On Swappa, our unlocked iPhone category is exclusively for factory unlocked iPhones. In addition to being sold factory unlocked, this also means the iPhone has been paid in full and is no longer being financed through a wireless carrier. Oftentimes, factory unlocked iPhones are sold as “SIM-free” models directly from Apple, although it’s still worth looking at the specific model number to make sure it’s compatible with your specific network (US model vs global model).
If you’re looking to find carrier unlocked iPhones — for instance, a specific AT&T iPhone model that you can use with your T-Mobile SIM card — then you’ll need to search for these types of listings under the normal AT&T carrier category. Again, Swappa doesn’t allow carrier-unlocked iPhones to be sold in our dedicated unlocked category.
Factory unlocked phones are occasionally a little more expensive than carrier-locked phones because they give you the freedom of being able to shop around for the best wireless plans and deals. But don’t worry — you’ll always get the best deals on Swappa, and we make buying even easier with Buy Now, Pay Later. Get the tech you want today, and pay for it in 4 easy installments spread over time.
Can an unlocked iPhone be used on any carrier?
Although an unlocked iPhone is not locked to a specific wireless carrier, it may still have some hardware restrictions (such as missing wireless bands required by your carrier) that prevent it from working 100% optimally on every wireless carrier. You’ll want to verify the unlocked iPhone model in question is compatible with your network before buying, something we hope to answer in this post.
Once you find the right unlocked iPhone for you, you can either order a SIM card from a wireless carrier you want to switch to or, if you already have wireless service, insert your existing SIM card into an unlocked iPhone, and it will activate on your network. Simple as that.

Unlocked iPhone 12 Pro Max carrier compatibility
Unlocked
If you are buying a used iPhone 12 Pro Max to use in the United States, you’ll want to look for the A2342. This is Apple’s only model specifically for the US market and it supports the major three carriers, as well as the numerous MVNO carriers that operate on those networks.
This means you will want iPhone 12 Pro Max A2342 if you are planning to use it with Verizon, AT&T, or T-Mobile, with model A2342 supporting both 5G and LTE networks for these carriers. Similarly, the A2342 iPhone 12 Pro Max will work with MVNO carriers like Mint Mobile, Cricket Wireless, US Cellular, Straight Talk, and more.
Here are the iPhone 12 Pro Max network bands for model A2342:
- 5G NR (Bands n1, n2, n3, n5, n7, n8, n12, n20, n25, n28, n38, n40, n41, n66, n71, n77, n78, n79)
- 5G NR mmWave (Bands n260, n261)
- FDD-LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 32, 66, 71)
- TD-LTE (Bands 34, 38, 39, 40, 41, 42, 46, 48)
- CDMA EV-DO Rev. A (800, 1900 MHz)
- UMTS / HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
- GSM / EDGE (850, 900, 1800, 1900 MHz)
Previous generations of the iPhone had specific model numbers for various carriers — even within the US market. But things have been simplified and the iPhone 12 Pro Max now has a single model number that supports all US carriers, including GSM, CDMA, 4G LTE, and 5G networks.
If you live outside the US or find yourself frequently traveling, you may check out the iPhone 12 Pro Max model number A2411 which is the global model. The A2411 offers support for a wide range of countries and you can find band support for 5G and LTE networks as follows:
| 5G | LTE |
|---|---|
| n1 (2100 MHz) | 1 (2100 MHz) |
| n2 (1900 MHz) | 2 (1900 MHz) |

Unlocked iPhone 12 Pro carrier compatibility
Unlocked
There are a handful of used iPhone 12 Pro model numbers for various regions around the world, but if you live in the United States, the iPhone 12 Pro model number you’ll want is the A2341. This is the model that supports all US-based carriers including Verizon, AT&T, and T-Mobile — with support for both their 4G LTE and 5G networks.
In addition to supporting the big three wireless carriers, the A2341 will also support various smaller carriers (MVNOs) such as Mint Mobile, Cricket Wireless, US Cellular, Straight Talk, and others.
Here are the iPhone 12 Pro network bands for model A2341:
- 5G NR (Bands n1, n2, n3, n5, n7, n8, n12, n20, n25, n28, n38, n40, n41, n66, n71, n77, n78, n79)
- 5G NR mmWave (Bands n260, n261)
- FDD-LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 32, 66, 71)
- TD-LTE (Bands 34, 38, 39, 40, 41, 42, 46, 48)
- CDMA EV-DO Rev. A (800, 1900 MHz)
- UMTS / HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
- GSM / EDGE (850, 900, 1800, 1900 MHz)
In the past, US carriers used different bands for their networks, meaning you’d need a carrier-specific iPhone for the carrier you planned to use. Luckily, the iPhone 12 Pro has a single model number that supports all US carriers. This includes support for both GSM and CDMA networks, as well as 4G LTE and 5G bands. Of course, there are other models available outside the US market, so if you are buying a used iPhone 12 Pro, you’ll want to double-check the model number to ensure full carrier compatibility.
iPhone 12 Pro model numbers for other markets (countries) include the A2406, A2407, and the A2408. It’s the iPhone 12 Pro A2407 that’s considered the “global” model and offers support for a wide range of countries around the world. For the iPhone 12 Pro A2407 (global), band support is as follows:
| 5G | LTE |
|---|---|
| n1 (2100 MHz) | 1 (2100 MHz) |
| n2 (1900 MHz) | 2 (1900 MHz) |

Unlocked iPhone 12 mini carrier compatibility
Unlocked
Apple announced the iPhone 12 on October 13, 2020. The iPhone 12 becomes the 14th generation of the iPhone, and the full lineup consists of the iPhone 12, iPhone 12 mini, iPhone 12 Pro, and the iPhone 12 Pro Max. In this post, we’ll be going over the various model numbers that are available for the iPhone 12 mini.
If you are buying a used iPhone 12 mini for use in the United States, you will want the A2176. This model number is available for the U.S. market and it supports 5G and LTE connectivity for all three of the major wireless providers: AT&T, Verizon, and T-Mobile. Model number A2176 also supports most MVNO carriers that make use of the big three carrier networks. This includes Mint Mobile, Cricket Wireless, US Cellular, Straight Talk, and many others.
The bottom line is that you will want iPhone 12 mini model A2176 if you are planning to use the phone with any of the three major wireless providers, or through an MVNO that uses any of the big three associated networks.
Here are the iPhone 12 mini network bands for model A2176:
- 5G NR (Bands n1, n2, n3, n5, n7, n8, n12, n20, n25, n28, n38, n40, n41, n66, n71, n77, n78, n79)
- 5G NR mmWave (Bands n260, n261)
- FDD‑LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 32, 66, 71)
- TD‑LTE (Bands 34, 38, 39, 40, 41, 42, 46, 48)
- CDMA EV-DO Rev. A (800, 1900 MHz)
- UMTS/HSPA+/DC‑HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
- GSM/EDGE (850, 900, 1800, 1900 MHz)
Earlier generations of the iPhone often had more than one model number available for each market. Here in the United States, that often meant figuring out if the model was compatible with GSM networks, or CDMA networks. Apple has since simplified this, and the iPhone 12 mini has a single model number that supports all U.S. carrier networks. This means model number A2176 includes support for GSM and CDMA as well as 4G LTE and 5G networks.
If you are planning to use your iPhone 12 mini outside the United States — model number A2176 is not your best option. If you are shopping for an iPhone 12 mini to use in other parts of the world, model number A2399 is the global model and offers support for a wide range of countries. Band support for 5G and LTE networks for the iPhone 12 mini A2399 are as follows:
| 5G | LTE |
|---|---|
| n1 (2100 MHz) | 1 (2100 MHz) |
| n2 (1900 MHz) | 2 (1900 MHz) |
| n3 (1800 MHz) | 3 (1800 MHz) |
| n5 (850 MHz) | 4 (AWS) |
| n7 (2600 MHz) | 5 (850 MHz) |
| n8 (900 MHz) | 7 (2600 MHz) |
| n12 (700 MHz) | 8 (900 MHz) |
| n20 (800 DD) | 12 (700 MHz) |
| n25 (1900 MHz) | 13 (700c MHz) |
| n28 (700 APT) | 17 (700b MHz) |
| n38 (TD 2600) | 18 (800 MHz) |
| n40 (TD 2300) | 19 (800 MHz) |

Unlocked iPhone 12 carrier compatibility

If you are buying a cheap iPhone 12 for use in the United States, you will want the A2172. This single model number is available for the U.S. market and it supports all three of the major carriers; AT&T, Verizon, and T-Mobile.
Model number A2172 also offers support for most MVNO carriers that make use of the big three carrier networks. The MVNO support includes Mint Mobile, Cricket Wireless, US Cellular, Straight Talk, and many others.
The bottom line is that you will want iPhone 12 model A2172 if you are planning to use your phone with Verizon, AT&T, or T-Mobile, or through an MVNO using any of the big three associated networks. And, because there is a single iPhone 12 model for the U.S. market, this also means that the iPhone 12 model A2172 supports 5G and LTE networks.
Here are the iPhone 12 network bands for model A2172:
- 5G NR (Bands n1, n2, n3, n5, n7, n8, n12, n20, n25, n28, n38, n40, n41, n66, n71, n77, n78, n79)
- 5G NR mmWave (Bands n260, n261)
- FDD‑LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 32, 66, 71)
- TD‑LTE (Bands 34, 38, 39, 40, 41, 42, 46, 48)
- CDMA EV-DO Rev. A (800, 1900 MHz)
- UMTS/HSPA+/DC‑HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
- GSM/EDGE (850, 900, 1800, 1900 MHz)
Some of the earlier generations of the iPhone meant there would be more than one model number available for each market. In the U.S. that often meant trying to make sure the model was compatible with GSM networks, or CDMA networks. But thankfully, this has been simplified and the iPhone 12 has a single model number that supports all U.S. carrier networks. This means model number A2172 includes support for GSM and CDMA as well as 4G LTE and 5G networks.
If you live outside the United States or are planning any extended travel outside the United States — the A2172 will not be your best option. If you fall into this group, you should keep reading to ensure you pick up the correct iPhone 12 “A” model number for your country or region.
Model number A2403 is the global model and offers support for a wide range of countries. Band support for 5G and LTE networks for the iPhone 12 A2403 is as follows:
| 5G | LTE |

Unlocked iPhone SE 2020 carrier compatibility
The iPhone SE 2nd Generation launched in April 2020 with a single unlocked model for North America: A2275. The iPhone SE A2275 is the “SIM-free” factory-unlocked model you’ll receive when buying directly from Apple. This is the model you’ll want to keep an eye out for if you’re in the US and buying a used iPhone SE 2020.
You can also find the iPhone SE A2296, which is Apple’s global model meant for the rest of the world (excluding the US and China). This model will support most carriers in Europe, the Middle East, and even Japan. Although the A2296 is closely related to the North American model, it lacks the A2275’s CDMA bands. There’s also an iPhone SE exclusively for China with the model number A2298.

A2275 and A2296 — what’s the difference??
The unlocked iPhone SE (2020) A2275 is the “SIM-free” option by Apple and is used for AppleCare replacement devices. This version is fully compatible with all wireless carriers in the US — working on both GSM and CDMA networks — so if you’re looking for an unlocked iPhone SE (2020) that works with AT&T, Verizon, or T-Mobile, the A2275 is your best bet.
Meanwhile, the A2296 has support for GSM networks inside and outside of the US (AT&T and T-Mobile for example) but doesn’t fully support CDMA networks like Sprint or Verizon. This may not be a big deal as most carriers have already begun to retire their CMDA networks in favor of 4G LTE and now 5G. Seeing as how Apple doesn’t offer this model in the states, it’s not something you can find as easily.
Unlocked iPhone 11 carrier compatibility
There are three different models for the iPhone 11, the A2111, A2221, and the A2223. The A2111 is the model you’ll most often find in the US and Canada, and the A2221 is the global (International) model. The A2223 is limited to China and Hong Kong, so for the purpose of this compatibility guide, we’ll be focusing on the A2111 and the A2221.
The A2111 and A2221 each support many of the same carrier bands, and each can be used in the United States. However, there are some differences in band support, and depending on your carrier — there may be some limitations with US carriers if you have the A2221.
A2111 vs A2221 — what’s the difference?
If you are located in the United States — you will most often find the A2111. Apple offers the A2111, and the most common Unlocked iPhone 11 here on Swappa is also the A2111. The A2111 has support for GSM and CDMA networks, which means you will have the widest support for US carriers.

iPhone 11 (A2111) – United States and Canada
- FDD‑LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 29, 30, 66, 71)
- TD‑LTE (Bands 34, 38, 39, 40, 41, 42, 46, 48)

*Found on the A2111, but not on the A2221 – FDD-LTE (Bands 14, 71), CDMA EV‑DO Rev. A (800, 1900 MHz)
Bottom line, if you are looking for an Unlocked iPhone 11 for use with a US carrier — the A2111 is the model you should first consider.
Unlocked iPhone 11 Pro carrier compatibility
A2160 vs A2215 — what’s the difference?
Apple launched the iPhone 11 Pro in September 2019. And just like its bigger brother, the iPhone 11 Pro Max (compatibility guide), there is just a single unlocked iPhone 11 Pro model for carriers in the North American market: the A2160. This makes it incredibly simple to buy an iPhone 11 Pro that is fully compatible with North American carriers.
Apple also launched the A2215, otherwise known as the “international model,” which has better support for the network bands used by international carriers. In addition, there is also a version with dual physical SIM slots known as the A2217. However, the A2217 is only available in China and Hong Kong.
| iPhone 11 Pro (A2160) | iPhone 11 Pro (A2215) |
|---|---|
|
|
The A2160 is the model intended for the North American market, and it is fully compatible with both CDMA and GSM networks. It is available SIM-free and factory-unlocked directly from Apple, as well as from all of the major US carriers. This version is compatible with all wireless carriers in the US, thanks to its ability to operate both on GSM and CDMA networks. So if you’re looking for an unlocked iPhone 11 Pro that works on all US carriers, the A2160 is your best bet.
The A2215, on the other hand, was released in European and Asian markets. It is compatible with LTE networks and supports GSM fallback on carriers such as AT&T and T-Mobile. Known as the “international model,” it has better support for the network bands used by worldwide carriers. However, it doesn’t fully support Verizon’s or Sprint’s legacy 3G CDMA networks. This isn’t a major issue, however, as Verizon and Sprint are in the process of retiring their legacy CDMA networks in favor of nationwide 4G LTE.
Unlocked iPhone 11 Pro Max carrier compatibility
A2161 vs A2218 — what’s the difference?
Apple launched the iPhone 11 Pro Max in September 2019. Just like its little brother, the iPhone 11 Pro (compatibility guide), the unlocked iPhone 11 Pro Max launched with a single model for North American carriers: the A2161. This is the version that you can buy through carriers in the US, as well as unlocked through the Apple Store.
Apple also launched the A2218, which is also known as the “international model,” which offers better support for the network bands used by international carriers, but lacks support for legacy 3G CDMA networks currently in use on Verizon and Sprint. Finally, there’s also the A2220, which includes dual physical SIM slots and is sold exclusively in China and Hong Kong.
| iPhone 11 Pro Max (A2161) | iPhone 11 Pro Max (A2218) |
|---|---|
|
|
The A2161 is the model intended for use in the North American market — and as such, it is fully compatible with CDMA and GSM networks. You can buy the A2161 through all of the major US carriers, as well as SIM-free and factory-unlocked directly from the Apple Store. If you’re looking for a device that will primarily see use in North America, the A2161 is the iPhone to buy.
The A2218 is known as the “international model,” and it is intended for European and Asian markets. It can be used in the US on LTE networks and is compatible with the majority of common LTE bands worldwide. The A2218 supports legacy GSM networks on carriers such as AT&T and T-Mobile, but it does not support Verizon’s and Sprint’s legacy 3G CDMA networks. However, this shouldn’t be a deal-breaker for most since Verizon and Sprint are in the process of retiring these networks in favor of nationwide 4G LTE.
Unlocked iPhone XR carrier compatibility
Apple has a handful of different models for the iPhone XR. In total, you’ll find the A1984, A2105, A2106, A2107, and A2108. The A1984 is the model you will most often find when shipping here in the US, however, the A2105 also offers support for some US carriers. The A2106 is the Japanese model, and the A2107 and A2108 are both for mainland China.
A1984 vs A2105 — what’s the difference?
As we are highlighting US carrier support for the Unlocked iPhone XR — we will be focusing on the A1984 and the A2105. Both models are supported here in the US, however, the A1984 has full support for GSM and CDMA networks, which means it will have the widest support for US carriers. The A2105 does not offer the same CDMA support, so carrier support for Verizon may be limited.

Unlocked iPhone XS carrier compatibility
A1920 vs A2097 — what’s the difference?
In 2018, Apple made it easy for people looking for an unlocked iPhone XS that works on their carrier. In 2018, Apple introduced only a single unlocked iPhone XS model for carriers in the USA: A1920. The unlocked US variant makes it dead simple to figure out which unlocked iPhone XS is compatible with your wireless carrier.
Keep in mind there’s also the iPhone XS A2097 which is the “global model” for European and Asian markets (although it also shares some compatibility with US carriers), and an A2098 model intended for Japanese carriers. So, what’s the difference between the unlocked iPhone XS A1920 (US) and A2091 (Europe)?
The A1920 is the GSM+CDMA model and is fully compatible with any US carrier including AT&T, Verizon, T-Mobile, and Sprint. The A2091, on the other hand, is Apple’s GSM-only version and does not support CDMA networks. To find out which unlocked iPhone XS model will work for your carrier, see the table below.
| iPhone XS (1920) | iPhone XS (A2091) |
|---|---|
|
|
The A1920 is the de facto iPhone XS for the US, once sold as the “SIM-free” option by Apple and used for AppleCare replacement devices. This version is fully compatible with all wireless carriers in the US — working on both GSM and CDMA networks — and is the preferred model for anyone living in the states. If you want an unlocked iPhone XS that works with AT&T, Verizon, or T-Mobile and Sprint.
Meanwhile, the A2091 has better support for GSM networks (AT&T and T-Mobile) and worldwide carriers but doesn’t fully support CDMA networks (Sprint and Verizon’s 2G/3G network). This shouldn’t be a big deal since most carriers are already in the process of retiring their CMDA networks in favor of 4G LTE, something the A2091 does support.
Unlocked iPhone XS Max carrier compatibility
A1921 vs A2101 — what’s the difference?
In 2018, Apple introduced only one unlocked iPhone XS Max model for carriers in the USA: A1921. With only a single unlocked US variant, this makes it dead simple to figure out which unlocked iPhone XS Max is compatible with your wireless carrier.
There’s also the iPhone XS Max A2101 which is the “global model” for European and Asian markets (although it also shares some compatibility with US carriers), and an A2102 model intended for Japanese carriers. So, what’s the difference between the unlocked iPhone XS Max A1921 (US) and A2101 (EU)?
The A1920 is the GSM+CDMA model and is fully compatible with any US carrier including AT&T, Verizon, T-Mobile, and Sprint. The A2091, on the other hand, is GSM-only and does not support CDMA networks. Both the A2101 and A1920 have dual SIM functionality (eSIM+nano SIM). To find out which unlocked iPhone XS Max model works on your carrier, see the table below.
| iPhone XS Max (1921) | iPhone XS Max (A2101) |
|---|---|
|
|
The A1921 is the only unlocked iPhone XS Max for the US wireless carriers. This is the version Apple offers as their “SIM-free” model and is used for AppleCare replacement devices. This model is fully compatible with all wireless carriers in the US — working on both GSM and CDMA networks — and is the preferred model for anyone living in the states. If you want an unlocked iPhone XS Max that works with AT&T, Verizon, T-Mobile, or any MVNO in the US, the A1921 is your best bet.
Meanwhile, the A2101 is compatible with GSM networks (AT&T and T-Mobile) and while it has better support for worldwide carriers, it doesn’t fully support Verizon or Sprint’s 2G/3G CDMA networks. This shouldn’t be an issue as most US carriers are already in the process of retiring their CDMA networks in favor of 4G LTE, something the A2101 supports.
Unlocked iPhone X carrier compatibility
You can find two models of the unlocked iPhone X for US carriers: A1865 and A1901. There is also an A1902 model, but it’s strictly for Japanese carriers so we’ll be leaving it out of this post. For now, let’s focus on the only two US iPhone X models you should be caring about.
So, what’s the difference between the unlocked iPhone X A1865 and A1901, and more importantly, which model is compatible with your carrier network? Let’s go over the differences in carrier compatibility which should help you find the right iPhone X for Verizon, AT&T, T-Mobile, or your favorite prepaid MVNO.
A1865 vs A1901 — what’s the difference?
The iPhone X A1865 is the GSM+CDMA model and works on any US carrier, including Verizon. Meanwhile, the iPhone X A1901 is the GSM-only version — sold as the AT&T and T-Mobile carrier model — and is not 100% compatible with CDMA networks.
| iPhone X (A1865) | iPhone X (A1901) |
|---|---|
|

A1865 models have full CDMA support, which is what Verizon and Sprint use for their 2G and 3G connectivity. Although the A1901 will not support Verizon or Sprint 3G CDMA, it is compatible with their 4G LTE bands, which still makes it a viable option if you’re on those networks.
The A1865 is sold by Apple as the “SIM-free” model and is typically used by Apple for replacement devices, so if you want an iPhone that offers 100% compatibility with all four major US carriers (and a potentially better resale value), your best bet is to go with the A1865 model.
That doesn’t you should ignore the A1901 model (even if you’re on Verizon), especially if you come across a great deal. Whichever model you decide to go with, you can start shopping for unlocked iPhone X deals on Swappa by clicking the widget below.
Unlocked iPhone 8 carrier compatibility
A1863 vs A1905 — what’s the difference?
The unlocked iPhone 8 comes in two US carrier models: A1863 and A1905. There’s also the A1906 model, but it is intended for Japanese carriers so we’ll be leaving it out of this post. So, what’s the difference between the unlocked iPhone 8 A1863 and A1905?
The A1863 is the GSM+CDMA model that works on all US carriers, including AT&T, T-Mobile, and Verizon. Meanwhile, the A1905 is the GSM-only version — sold as the AT&T and T-Mobile carrier model — and is not 100% compatible with CDMA networks.
| iPhone 8 (A1863) | iPhone 8 (A1905) |
|---|---|
|
|
A1863 models offer full CDMA support, which is network technology Verizon uses for 2G and 3G connectivity. Meanwhile, the A1905 will not support Verizon’s CDMA networks (2G/3G) but is still compatible with their 4G LTE bands. This means the A1905 could still be a viable option if you already have a Verizon SIM.
The A1863 is sold by Apple as their “SIM-free” model and is typically used by Apple for replacement devices. So, if you want a phone that works on all three carriers, you’ll need to get the A1863 model.
Unlocked iPhone 8 Plus carrier compatibility
A1864 vs A1897 — what’s the difference?
The unlocked iPhone 8 Plus comes in two US carrier models: A1864 and A1897. There is also model A1898, but it is intended for Japanese carriers and isn’t covered in this article. So, what’s the difference between the unlocked iPhone 8 Plus A1864 and A1897?
The A1864 is the GSM+CDMA model and works with any US carrier, including AT&T, Verizon, and T-Mobile. Meanwhile, the A1897 is the GSM-only version — sold as the AT&T and T-Mobile carrier model — and does not support CDMA networks.
| iPhone 8 Plus (A1864) | iPhone 8 Plus (A1897) |
|---|---|
|

The A1864 offers full CDMA support (the wireless technology behind Verizon and Sprint’s 3G networks) and is sold by Apple as their “SIM-free” model, typically used by Apple for replacement devices. If you want a phone that works on all three carriers and has a potentially higher resale value, you’ll want to go with the A1864 model.
The A1897, on the other hand, does not support Verizon’s 3G CDMA networks but is still compatible with their 4G LTE bands. This means the A1897 could still be a viable option for those already with Verizon, especially if you find a great deal on this particular model.
