# Swappa Devices, Questions and Answers ## What is an unlocked device? Smartphones can be locked or unlocked. A carrier-locked smartphone is only meant for use with a specific wireless carrier. An [unlocked smartphone](https://swappa.com/buy/unlocked) can be used with any carrier with compatible bands. Unlocked smartphones can either be carrier-unlocked or factory-unlocked. Swappa only allows factory-unlocked devices to be listed in the unlocked category. Devices that were originally purchased from, or locked to a specific carrier, must be listed under their original carrier. * **Carrier unlocked:** Originally purchased from or locked to a single wireless carrier, but later unlocked by the carrier for use on other carrier networks. * **Factory unlocked:** Often originally purchased directly from the manufacturer, and has never been locked to a specific carrier. * **Flex Device:** US Reseller Flex Policy, also known as [SIM OUT](https://swappa.com/faq/answer/us-reseller-flex-policy), allows retail stores to sell devices that have not yet been locked for use on a specific US cell carrier. However, these devices will lock to the first US carrier they connect to after inserting a compatible SIM card. **Network Compatibility:** Not all unlocked devices are compatible with all carriers. For example, an unlocked smartphone intended for use with a US carrier may not work with an international carrier. **Unlocked Non-US:** Swappa is a U.S.-based marketplace, but we do include a category for international factory unlocked devices, labeled as "Unlocked Non-US". Devices in this category might work in the U.S., but buyers are expected to confirm compatibility with their carrier prior to purchasing an "Unlocked Non-US" device. **Samsung U vs U1:** Factory unlocked U1 Samsung devices should be listed in the unlocked section. Samsung carrier U devices **must** be listed in the original carrier section, even if sim unlocked or software flashed. **Google Pixel:** Only factory unlocked Google edition Pixels should be listed in the unlocked section. Carrier Pixels **must** be listed in the original carrier section, even if sim locked, due to bootloader restrictions. Learn more about carrier compatibility on the Swappa blog: * [Unlocked iPhone Carrier Compatibility Guide](https://swappa.com/blog/unlocked-iphone-buyers-guide/) * [Android Phone Compatibility Guides](https://swappa.com/blog/tag/carrier-compatibility-guide/) ## What criteria does a product have to meet to be listed on Swappa? Devices must meet the following criteria to be listed for sale on Swappa: * Fully functional * No cracked or chipped glass, water damage, or structural issues * Clean IMEI / ESN and ready for activation * No OS or activation lock * Must not be financed or leased * Must comply with [Swappa's Terms of Use](https://swappa.com/terms) Devices listed for sale on Swappa can be listed in [New, Mint, Good, or Fair condition](https://swappa.com/faq/general/condition-requirements). Under certain circumstances, some devices cannot be sold on Swappa: * Devices returned to a seller and repaired more than once due to functional issues * Devices that have been factory recalled for defects * Devices marked "Not for Resale" * Device is a pre-production or demo unit * Device chargers and power cables that have frayed or exposed wires Note: Trade-in devices have a different set of criteria requirements. Review details of Swappa's [Trade-In Program](https://swappa.com/trade-in), or review the [trade-in FAQs](https://swappa.com/faq/trade-in). ---- ### Fully Functional All hardware and software features must work, including the display, camera, buttons, ports, and the battery, which needs to properly charge and discharge (see our [iPhone specific battery criteria here](https://swappa.com/faq/answer/apple-battery-health-requirements)). Simply put, if the device had a hardware or software feature from the factory, those features need to be working in order to be listed for sale on Swappa. ### Device Integrity Devices cannot have any structural issues such as any cracked (or chipped) glass, or broken buttons, keys, or switches, and the SIM card tray cannot be missing or damaged. Devices with water damage or missing moisture indicator stickers cannot be listed. Devices that are advertised as waterproof must include all port covers and other functionality that make them waterproof, if applicable. ### IMEI / ESN Integrity All devices must be clean and ready for activation. * The device IMEI / ESN cannot be blocklisted. * The hardware and software IMEI / ESN must match. * If the device IMEI / ESN has been altered or "repaired" it cannot be listed. Use Swappa’s [free ESN / IMEI checker](https://swappa.com/imei) to verify the integrity of your device. ### OS Lock Devices need to be fully reset, free of any operating system software / activation locks, and ready for activation before they are listed for sale on Swappa. Operating System software / activation locks include (but are not limited to): * Apple iCloud * Google Android Factory Reset Protections * Remote Management Software (RMS) * Mobile Device Management (MDM) ### Outstanding Financial Obligation Devices must be fully paid off – devices on equipment installation plans (EIP) or standard contracts cannot be listed until they are paid off. ---- ## What is an ESN number? An ESN (Electronic Serial Number) is a unique identifier tied to all cellular devices. ESNs can be found in a few different formats. The most common is the IMEI (International Mobile Equipment Identity). However, some older mobile devices have a MEID (Mobile Equipment Identifier). No two devices should ever have the same ESN / IMEI, and reviewing this number is one of the most important steps in Swappa's [listing review process](https://swappa.com/faq/esn/listing-reviewed-approved). Thus, it's crucial to ensure that you provide the [proper ESN](https://swappa.com/faq/esn/serial-number-field) when creating a listing on Swappa. - Check the status of your phone with Swappa’s **[free ESN check](https://swappa.com/imei)** - Learn more on the Swappa Blog: **[How to find your phone’s IMEI / ESN](https://swappa.com/blog/how-to-find-imei/)** ## How do I factory reset my device and prepare it for sale? Devices must be factory reset prior to being listed on Swappa. The steps will vary from device to device, but we’ve compiled a few resources to help you below. **Please note:** Swappa is not responsible for any lost data.

Unlocked devices can generally be used on any compatible cellular network, rather than being restricted to one specific cellular provider. A phone can be factory unlocked, meaning it’s originally sold as unlocked. Or a phone can be carrier unlocked, meaning it’s originally just for one carrier, but is then unlocked by that carrier for broader use on other carriers (such as an MVNO). On Swappa, our unlocked device categories are for factory unlocked devices that are not and were not previously restricted to a single carrier. [Why buy an Unlocked phone?

No, devices with cracked or chipped glass cannot be sold on Swappa. This includes all glass on the device, such as the screen, body, back, and camera lens. Swappa has a strict No Junk policy. That means tech has to work in order to be sold on Swappa. Learn more by reading Swappa's [listing criteria](https://swappa.com/faq/general/listing-device-criteria). ## What are the Apple Battery Health requirements on Swappa? Swappa requires all devices to meet certain [criteria requirements](https://swappa.com/faq/answer/listing-device-criteria) in order to be listed for sale. One of the requirements is having a fully functional battery. Swappa defines a fully functional battery as one that properly charges and discharges. Additionally, if you are listing an iPhone for sale on Swappa, and the battery health is below 80% and an Apple battery message is showing in the settings, this must be disclosed on the listing. Read more: [Understanding Apple's Battery Health](https://swappa.com/blog/swappa-understanding-apples-battery-health/) ## What is the US Reseller Flex Policy (SIM OUT)? The US Reseller Flex Policy, also known as SIM OUT, allows retail stores to sell devices that have not yet been locked for use on a specific US cell carrier. However, these devices are programmed to lock to the first US carrier they connect to after inserting a compatible SIM card. * For example, if the first SIM card inserted is from Verizon, the device will function exactly as if it was bought directly from Verizon, and the device will be locked to Verizon. * In addition, the first SIM card put into the device MUST be from a US cell carrier. If the first SIM card is not one from a US cell carrier, the SIM card will not be activated on that device. Due to how these US Reseller Flex Policy (SIM OUT) devices lock to the first cell carrier’s SIM, they cannot be listed in the [Unlocked](https://swappa.com/faq/answer/unlocked-device) category here on Swappa. If a seller wishes to list a device sold to them using the US Reseller Flex Policy, they must choose a specific US cell carrier in which to list the device. ## How do I select a SIM card add-on through Swappa? When purchasing an eligible listing, buyers can purchase a SIM card add-on at two different stages: right after making a purchase, and on the [sale page](https://swappa.com/faq/answer/sale-page) tied to the purchase. * The first option is shown right after making a purchase, but before proceeding to the sale page * Otherwise, the sale page will display a promotion box where this can be selected after purchase SIM card options will only be shown when purchasing a device that displays a small badge for the carrier on the listing page, so please be on the lookout for this before making a purchase if you wish to order a SIM card at the same time. ## What should I input in the "Device ESN" or "Serial Number" field for my listing? Serial numbers are typically required when listing products for sale on Swappa because we check them during the [listing review process](https://swappa.com/faq/sell/listing-reviewed-approved). * **Smartphones and other cellular devices:** Provide your [IMEI number](https://swappa.com/faq/sell/what-is-imei) * **Phones with Dual or Digital SIM:** Provide the IMEI number for the primary SIM (not the secondary or digital eSIM) * **WiFi-only devices like laptops and game consoles:** Provide the serial number. Finding your IMEI or serial number will differ from device to device. [Click here](https://swappa.com/faq/sell/how-to-find-esn) to learn how to find the serial number on many common devices. ## Should SIM cards be included with devices sold on Swappa? SIM cards should not be included with devices sold on Swappa. * Buyers are responsible for supplying their own SIM card obtained from their carrier or pulled from their existing device * Sellers need remove their SIM card before shipping a device to the buyer. The primary exception to this is for devices that come with a SIM card and are listed as New, which means the box is unopened and still sealed from the factory. * Sellers need to remove any cellular plans attached to the eSIM card of the device. ## Can I sell a device if it's iCloud locked or blocked by any other software locks? Devices that are locked by any software limitations cannot be listed for sale on Swappa. Common software locks include: * Apple devices that are locked via [iCloud](https://support.apple.com/guide/icloud/remove-a-device-mmfc0eeddd/icloud) or [MDM](https://support.apple.com/guide/deployment/intro-to-mdm-depc0aadd3fe/web) * Android devices that are locked via [Android Factory Reset Protection](https://support.google.com/android/answer/9459346?hl=en) * Windows devices that are locked via [Microsoft's Find My Device](https://support.microsoft.com/en-us/windows/remove-a-device-from-your-microsoft-account-dda2c664-9d57-e5db-acf0-67f14d5fdf3c) All products listed for sale on Swappa must be [fully reset](https://swappa.com/faq/sell/factory-reset) (and fully functional) when shipped to a buyer. Swappa’s full listing device criteria requirements can be found in our [FAQ](https://swappa.com/faq/sell/listing-device-criteria). ## Can modified devices be sold on Swappa? Swappa allows jailbroken or rooted phones and tablets to be listed for sale, along with phones or tablets running a custom ROM (modified version of the operating system). Other devices with software modifications cannot be listed for sale unless they are fully restored to a factory state. This extends to all other devices in our marketplace such as laptops, game consoles, etc. For any phone or tablet listings: * The seller is required to note any modifications in the listing description * The seller is required to note any device limitations (for example, Samsung Pay may not work after tripping Samsung Knox) in the listing description Any phones or tablets with flashed or modified firmware must also be ready for activation in the carrier category they're listed under. For example, if you have a device that was purchased through one carrier but has been modified with firmware intended for another carrier, the device is required to be fully functional on the original carrier's network. As a buyer, if you're not familiar with what these different terms mean, please be sure to hold off on purchasing any listings that mention them being jailbroken, rooted, or software modified. Please also note that many devices are also void of any [manufacturer warranties](https://swappa.com/faq/sell/manufacturer-warranty) once they have been jailbroken, rooted, or modified by flashing a custom ROM. We also recommend that any devices running a beta operating system be restored back to the stable version of the OS before listing it for sale. Here are some helpful manufacturer pages for a few common device types to assist with this: * [Restore iOS to stable version](https://beta.apple.com/sp/betaprogram/restore#ios) * [Restore macOS to stable version](https://beta.apple.com/sp/betaprogram/restore#macos) * [Restore Windows to stable version](https://insider.windows.com/en-us/leave-program) * [Restore Chrome OS to stable channel](https://support.google.com/chromebook/answer/1086915?hl=en) * [Return Android to stable version (for Pixel devices)](https://www.google.com/android/beta#faq) ## Are warranty replacements or refurbished devices allowed for sale on Swappa? Yes, refurbished devices and warranty replacement devices can be sold on Swappa. In order for a refurbished device to be listed: * The device needs to be restored to full working order by a repair professional through the replacement of any defective parts. * All repairs must be disclosed by the seller on the listing. * Non-OEM parts are allowed if disclosed by the seller and the device is [fully functional](https://swappa.com/faq/answer/listing-device-criteria). Warranty replacement devices (and refurbished devices) cannot be listed as “New” on Swappa, even if they are in a sealed box. Swappa’s [“New” condition category](https://swappa.com/faq/general/condition-requirements) is only for items that are factory sealed in unopened retail packaging. ## Why am I unable to list older devices?

Please include as much information as you can about the product, including a link to the manufacturer’s website and any other pertinent details.

Here at Swappa we welcome all devices that our product catalog team have made listings for. This categories are not only for U.S. domestic devices but for devices made for and sold outside the U.S. to consumers. However Swappa still remains a U.S. based online marketplace so with that, there are some limitations on international devices that can be listed and here on Swappa. * All laptops must have a English alphabet keyboard QWERTY layout (BS 4822 standard) * Any gaming console must be the model sold in the U.S. with the U.S. charging cord. No international versions of gaming consoles will be allowed. ## Are refurbished devices allowed on Swappa? Yes, refurbished devices and warranty replacement devices can be sold on Swappa. In order for a refurbished device to be listed: * The device needs to be restored to full working order by a repair professional through the replacement of any defective parts. * All repairs must be disclosed by the seller on the listing. * Non-OEM parts are allowed if disclosed by the seller and the device is [fully functional](https://swappa.com/faq/answer/listing-device-criteria). Warranty replacement devices (and refurbished devices) cannot be listed as “New” on Swappa, even if they are in a sealed box. Swappa’s [“New” condition category](https://swappa.com/faq/general/condition-requirements) is only for items that are factory sealed in unopened retail packaging. ## Can I list a device with pre-installed applications or digital games? Swappa requires that all devices are [factory reset](https://swappa.com/faq/general/factory-reset) before they are shipped to a buyer. So unless the applications or digital games were on the device when it was new, they cannot be included when selling a device on Swappa. ## Can I sell a device that has screen burn-in and/or dead pixels? Devices that have *minor* burn-in or a *few* dead pixels, that do not interfere with the ability to view content on the screen, can be listed in the [Good or Fair condition category](https://swappa.com/faq/answer/condition-requirements), depending on the severity. If you are listing a device with burn-in or dead pixels, the issue must be mentioned in the listing description. We also recommend including a picture of the burn-in or dead pixels. Devices that have *major* burn-in or *more than a few* dead pixels, to the extent that it interferes with the ability to view content on the screen, should not be listed. Swappa also does not allow devices with major screen defects, such as large patches of dead pixels or colored lines running through the display to be listed. If you're not sure if your device should be listed, feel free to reach out to our support team using our [help form](https://swappa.com/help). ## Can I list a device on Swappa if a skin or wrap is applied? Devices with skins or wraps can be sold here on Swappa. The only limitation is that they can’t be listed in our [mint condition](https://swappa.com/faq/sell/condition-requirements) category unless the skin is removed. ## Can I sell my Galaxy Note or another similar device without the integrated stylus? Devices that originally came with an integrated stylus [cannot be listed](https://swappa.com/faq/answer/listing-device-criteria) without it. This is to help prevent failed sales where a buyer may overlook this missing detail. This means that all Samsung Galaxy Note, Nintendo 3DS, Galaxy S22 Ultra, and any tablet or laptop devices where an integrated stylus is originally included (one that is inserted into the device for holding) must have a fully functional stylus. If you'd like to sell a device like this but don't have a stylus, simply purchase a proper replacement before listing it on Swappa. Just be sure to note in your listing description that it was replaced! ## More Questions and Answers - [Marketplace FAQ](https://swappa.com/faq/marketplace.md) - [Buying FAQ](https://swappa.com/faq/buying.md) - [Selling FAQ](https://swappa.com/faq/selling.md) - [Payments FAQ](https://swappa.com/faq/payments.md) - [International FAQ](https://swappa.com/faq/international.md) - [Shipping FAQ](https://swappa.com/faq/shipping.md) - [Devices FAQ](https://swappa.com/faq/devices.md) - [Warranty FAQ](https://swappa.com/faq/warranty.md) - [ESN Check FAQ](https://swappa.com/faq/esn.md) - [Trade-In FAQ](https://swappa.com/faq/trade-in.md) - [AirPods FAQ](https://swappa.com/faq/airpods.md)
