Determining whether your Samsung Galaxy S21 Ultra 5G uses a single SIM or dual SIM configuration is essential before ordering a replacement SIM tray. The easiest way to check is by examining your current SIM tray when you eject it from the device. A single SIM tray has space for only one nano-SIM card, while a dual SIM tray has space for two nano-SIM cards or one nano-SIM plus a microSD card in hybrid configurations. You can also check your device model number in Settings by navigating to About Phone and looking at the Model Number field. Generally, models sold in Australia through major carriers like Telstra, Optus, and Vodafone are single SIM variants, while models purchased from international retailers or unlocked from certain regions may be dual SIM. The SM-G998B variant commonly sold in Europe and Australia is typically dual SIM capable, while SM-G998U sold through US carriers is often single SIM only. Additionally, you can check your device packaging or original documentation which usually specifies the SIM configuration. If you currently have mobile network connectivity with just one SIM card and there is no second SIM slot visible on your tray, you have a single SIM model and this Phantom Black replacement tray is the correct choice for your device.

A stuck SIM tray that refuses to eject is a common issue that can occur due to several reasons including debris accumulation, bent eject mechanism, physical damage to the tray, or internal component issues. Before attempting any forceful removal, first ensure you are using the correct tool and inserting it fully into the eject hole with firm but controlled pressure. The eject hole on the Galaxy S21 Ultra is located on the top edge of the device. Try using the original Samsung SIM eject tool if available, as generic paperclips may not be the correct diameter or length. If gentle pressure does not work, try inserting the tool while gently pulling the tray outward with your fingernail on the exposed edge. Avoid using excessive force as this can damage the internal spring mechanism or break the tray inside the phone, making extraction much more difficult. If the tray remains stuck after multiple careful attempts, we strongly recommend professional assistance rather than risking damage to your device. At JPC Mobile in Forest Lake, our technicians have specialized tools and experience to safely extract stuck SIM trays without damaging the internal slot mechanism. Once extracted, this replacement Phantom Black tray will restore full SIM card functionality to your Galaxy S21 Ultra.

Yes, this Phantom Black SIM tray is designed specifically for the Samsung Galaxy S21 Ultra 5G and is compatible with Australian models including those purchased from major retailers like JB Hi-Fi, Harvey Norman, Officeworks, and carrier stores including Telstra, Optus, and Vodafone. The Galaxy S21 Ultra sold in Australia typically carries model numbers SM-G998B or G998, both of which are fully compatible with this replacement tray. The Phantom Black colour finish is an exact match to the original Samsung Phantom Black devices, ensuring your replacement tray blends seamlessly with your phone's aesthetic without any visible colour difference. Australian models are generally 5G capable and this tray supports all network connectivity features without any compatibility concerns. Whether your device was purchased outright, on a plan, or as an unlocked handset, this SIM tray will function identically to the original equipment manufacturer part. The only consideration for Australian buyers is confirming whether your specific device uses a single SIM or dual SIM configuration, as this listing is for the single SIM variant. Most carrier-locked Australian devices are single SIM, making this the appropriate choice for the majority of Australian Galaxy S21 Ultra owners.

No, the Samsung Galaxy S21 Ultra 5G does not support microSD card storage expansion. Samsung made the design decision to remove the SD card slot starting with the Galaxy S21 series, meaning the SIM tray on all S21, S21 Plus, and S21 Ultra models is designed exclusively for SIM cards without any SD card functionality. This differs from earlier Galaxy S models like the S10 and S20 series which featured hybrid trays that could accept either a second SIM card or a microSD card for storage expansion. The Galaxy S21 Ultra comes with generous internal storage options ranging from 128GB to 512GB depending on the variant, and Samsung compensated for the lack of expandable storage by offering cloud storage solutions and larger base storage configurations. This single SIM replacement tray is the correct specification for the Galaxy S21 Ultra since there is no SD card slot to accommodate. If you require additional storage for your S21 Ultra, options include utilizing Samsung Cloud, Google Drive, or other cloud storage services, or transferring files via USB-C to external storage devices. The removal of SD card support allowed Samsung to make the device more water resistant and reduced internal component complexity.

The Samsung Galaxy S21 Ultra 5G uses a nano-SIM card, which is the smallest physical SIM card format currently in widespread use. The nano-SIM measures 12.3mm by 8.8mm and has been the standard SIM size for Samsung flagship devices for several years. If you are upgrading from another recent smartphone including any Samsung Galaxy S series from S6 onwards, most recent iPhone models from iPhone 5 onwards, or other modern Android devices, your existing SIM card should already be nano-SIM sized and will fit directly into this replacement tray without modification. If you are coming from an older device that uses a micro-SIM or standard SIM, you will need to contact your mobile carrier to obtain a new nano-SIM card with your existing number transferred. Most Australian carriers including Telstra, Optus, Vodafone, and MVNOs like Boost, Amaysim, and Woolworths Mobile can provide replacement nano-SIM cards either in-store or by mail, usually at no charge or for a small fee. When inserting your nano-SIM into this replacement tray, ensure the gold contact points face downward and the angled corner of the SIM card aligns with the angled corner of the tray slot for proper orientation and secure contact with the device's SIM reader.

SIM tray replacement is one of the simplest smartphone repairs and most users can successfully complete it at home without any specialized tools or technical expertise. The entire process takes less than two minutes and requires only a SIM eject tool, which is typically included with your phone or can be substituted with a straightened paperclip or earring post of similar diameter. The basic steps involve powering off your device, inserting the eject tool into the small hole next to the SIM tray slot until the tray pops out, transferring your SIM card from the old tray to the new replacement tray ensuring correct orientation, and gently sliding the new tray back into the phone until it sits flush with the device frame. However, professional installation is recommended in certain situations including when the old SIM tray is stuck or broken inside the device, when the SIM slot mechanism appears damaged, if you are uncomfortable handling small electronic components, or if previous insertion attempts have been unsuccessful. At JPC Mobile in Forest Lake, we can perform SIM tray replacement quickly and can also diagnose any underlying issues if your device is not recognizing SIM cards even with a new tray. Professional installation ensures the tray is seated correctly and the SIM slot mechanism is functioning properly.

A "No SIM card detected" error after inserting a new SIM tray can occur due to several reasons, most of which are easily resolved. First, ensure the SIM card is properly seated in the tray with the gold contacts facing down and the angled corner aligned correctly with the tray's corner cutout. Remove the tray and reseat the SIM card, ensuring it sits flat without any lifting at the edges. Next, verify the tray is fully inserted into the phone by pushing it gently until it clicks into place and sits completely flush with the device frame. If the SIM card is properly positioned and the tray is fully inserted, try restarting your Galaxy S21 Ultra as this clears temporary software glitches that can prevent SIM detection. Also check that your SIM card is not damaged, expired, or deactivated by your carrier by testing it in another compatible device if available. Clean both the SIM card gold contacts and the inside of the SIM tray with a soft dry cloth to remove any dust or fingerprint residue that might interfere with electrical contact. If the error persists after trying these steps, the issue may be with the SIM card reader mechanism inside the phone rather than the tray itself, which would require professional diagnosis and potential repair of the internal SIM slot connector.

The colour of the SIM tray is purely cosmetic and has absolutely no impact on functionality, network connectivity, or device performance. All Samsung Galaxy S21 Ultra SIM trays regardless of colour are manufactured to identical specifications with the same dimensions, materials, and tolerances to ensure perfect fit and reliable SIM card contact. The colour variation exists solely to match the various device finishes Samsung offers, including Phantom Black, Phantom Silver, Phantom Navy, and Phantom Titanium for the S21 Ultra. While using a different colour tray would not affect your phone's operation, many users prefer colour-matched components for aesthetic consistency, particularly since the SIM tray is visible on the edge of the device. This Phantom Black tray is specifically designed to match the Phantom Black Galaxy S21 Ultra finish, blending seamlessly when the tray is inserted. If your device is a different colour but you prefer black or cannot find a matching colour, using this tray will function identically with only a minor visual difference on the device edge. From a practical standpoint, the material composition, contact points, and structural integrity are identical across all colour variants of the S21 Ultra SIM tray.

This replacement SIM tray is manufactured to OEM-equivalent specifications meaning it matches the original Samsung part in terms of dimensions, material quality, colour accuracy, and functional performance. The tray is made from the same high-grade plastic and metal composite materials used in original equipment, ensuring durability through repeated insertions and removals over the lifetime of your device. The precision manufacturing process ensures exact dimensional accuracy so the tray slides smoothly into the SIM slot without forcing, binds, or excessive looseness, and sits perfectly flush with the device frame when fully inserted. The SIM card retention clips are designed to hold your nano-SIM securely in place during normal device use including drops and vibrations, while still allowing easy removal when needed. The Phantom Black colour finish is matched to Samsung's original Phantom Black specification so there is no visible colour difference when the tray is installed in your device. Every SIM tray we sell is tested before shipping to verify proper dimensions and clip functionality, ensuring you receive a part that performs identically to the original Samsung component. This quality standard means you get original-equivalent performance at a fraction of the cost of sourcing a replacement through Samsung official channels.
