vivo Y21d 4G 6GB RAM 128GB Storage

vivo Y21d Bangladesh model overview

The vivo Y21d Bangladesh model is a 4G smartphone built around the Unisoc T7225 platform, a 6.68-inch HD+ LCD with refresh rate up to 90Hz, and a 6500mAh typical-capacity battery. vivo Bangladesh lists a 6GB+128GB configuration priced at BDT 26,999 plus VAT; the official e-store and Star Tech selector both show this 6GB/128GB 4G option. That configuration also matches the catalog MSRP amount before VAT.

This catalog product has one variant and is mapped to 6GB LPDDR4X RAM and 128GB eMMC 5.1 storage. The exact BiponiBD sealed unit has not been inspected, so the order confirmation and box label still need to match. This is the Bangladesh Y21d 4G model. Do not confuse it with similarly named vivo devices or separate market configurations. The saved catalog MSRP is not a confirmed checkout total.

6.68-inch HD+ 90Hz display

vivo lists a 6.68-inch LCD with 1608 × 720 resolution, 264 PPI, up to 90Hz refresh rate, 83% NTSC color gamut and 1000-nit high-brightness mode. The large panel gives space for maps, messages, reading and video, while HD+ resolution offers less fine detail than Full HD. The HBM figure is a high-brightness mode measurement, not a claim that the screen stays at that brightness continuously in every scene.

A 90Hz display can make supported scrolling and interface motion look smoother, but it does not mean every app or video plays at 90 frames per second. Refresh rate depends on the application and system mode. vivo notes that the maximum refresh rate does not apply to all scenarios. No independent color, brightness or outdoor-legibility test was performed on the BiponiBD unit. Compare the display directly if fine text or sunlight visibility matters.

Unisoc T7225 processor correction

The official vivo Bangladesh specification identifies the Y21d processor as T7225, an octa-core platform on a 12nm process with two cores up to 1.8GHz and six cores up to 1.8GHz. The current catalog record and one Star Tech narrative section said Unisoc T612; Star Tech’s detailed specification table and vivo’s official Bangladesh page identify T7225. This product copy follows the manufacturer source and records the conflicting retailer narrative for traceability.

Processor name and clock speed are not benchmark results. App responsiveness and game performance depend on physical RAM, operating software, storage, heat, background tasks and network conditions. The catalog should not promise a frame rate or call this model a gaming phone on the basis of the chipset alone. Buyers comparing it with other Y-series models should verify the exact T7225 4G unit and memory tier.

6GB RAM and 128GB storage configuration

This catalog variant is mapped to 6GB LPDDR4X RAM and 128GB eMMC 5.1 storage. vivo Bangladesh publishes 6GB+128GB and 8GB+128GB options; its official page shows BDT 26,999 plus VAT for 6GB, and the official e-store selection is 6GB+128GB 4G. Star Tech’s selected local configuration is 6GB/128GB at the same pre-tax price point. This evidence supports the catalog mapping.

The operating system and preinstalled apps use some internal storage, leaving less free than the nominal 128GB. vivo also lists extended RAM implemented through software; this is virtual memory using storage and must not be presented as extra physical RAM. The Y21d 8GB tier is a distinct option and is not included in this single catalog variant. Check that the exact shipment label says 6GB+128GB before opening or setup.

microSD storage and dual-SIM tray

vivo Bangladesh lists expandable ROM up to 2TB with two nano-SIMs and one microSD card in the same dedicated tray arrangement. The official e-store describes the slot as dual SIM plus a dedicated microSD slot. This lets users keep two SIM cards and a memory card installed together, unlike hybrid trays that share the second SIM position. Check the physical tray and manufacturer documentation for the delivered regional unit.

The microSD card is not included unless the seller explicitly states it. A card can store compatible media and documents but does not make every app install to removable storage. The official maximum capacity is a manufacturer listing, not a statement that every card model or workload was tested. Back up important photos and files independently and verify card compatibility before relying on expansion as the only archive.

50MP rear camera and 0.08MP auxiliary camera

The Bangladesh specification lists a 50MP f/1.8 rear camera with an auxiliary 0.08MP f/3.0 camera and rear flash. Listed shooting modes include photo, night, portrait, video, live photo, slow motion, time-lapse, pro, panorama, documents, 50MP and underwater photography. The megapixel value describes the camera’s output specification; it does not guarantee sharpness or low-light performance. Scene conditions and image processing matter.

Underwater photography is a listed camera mode and does not mean routine underwater use is safe. vivo’s water-protection caveat warns against immersing the device in daily use and liquid ingress is excluded from warranty. There is no independent camera test of the BiponiBD unit in this review. Buyers who need detailed low-light or moving-subject images should compare sample photos from the same regional configuration and installed software.

5MP front camera and video

vivo lists a 5MP f/2.2 front camera and MP4 video recording. The model’s front-camera modes include photo, night, portrait, video and live photo; dual-view features are limited to models with at least 8GB RAM. That restriction matters for this 6GB catalog mapping, so this copy does not imply every family-level camera mode is available on the mapped variant.

Camera quality is affected by lighting, movement, focus, camera software and the app used to capture or share media. The official Bangladesh table does not give a detailed resolution/fps line for video recording, so this listing avoids adding unsupported video specifications from a retailer. Check the delivered phone’s camera settings if a specific mode, video resolution or microphone setup is essential.

6500mAh battery and 44W charging

vivo states a 6500mAh typical battery and 6355mAh rated capacity, with charging power up to 44W. Battery runtime depends on display brightness and refresh settings, mobile signal, video, navigation, games, background applications and battery age. The stated capacity is manufacturer data and does not predict a fixed number of hours for every user. The model specification identifies a 44W-capable vivo standard charger.

Charging power changes dynamically with use and conditions; a third-party charger or damaged cable may not provide the same behavior. vivo’s official package information lists a charger and USB cable, but confirm the exact BiponiBD bundle at checkout. Avoid charging when the phone is wet. The manufacturer cautions users to dry the device and USB port after liquid exposure and not to charge it while wet.

IP68/IP69 ratings and safe use

vivo says the Y21d was tested under controlled laboratory conditions and rated IP68 and IP69 under IEC 60529-2013. The official note describes the IP68 test as static fresh water up to 1.5 metres for up to 30 minutes and provides specified controlled conditions for IP69 testing. vivo also says the device is not a professional waterproof phone and that protection is not permanent. This rating does not justify routine immersion.

The manufacturer warns against seawater, beverages and other liquids, says resistance can decline through daily use and excludes liquid-ingress damage from warranty. Impacts, wear, repairs or damaged seals may change protection. Describe the ratings and test limits accurately; do not call the phone waterproof or encourage use underwater. If the device gets wet, follow vivo’s care guidance and do not connect the charger until the port is dry.

Network bands, SIM and NFC

For Bangladesh, vivo lists GSM 850/900/1800MHz, WCDMA B1/B5/B8, LTE FDD B1/B3/B5/B7/B8/B20/B28 and LTE TDD B38/B40/B41. It supports dual nano-SIM dual standby plus a dedicated microSD slot. Carrier availability and functionality depend on network coverage, regulations, infrastructure and software. This is the 4G Y21d variant; no 5G support is claimed.

The official Bangladesh specification explicitly says NFC is not supported. That matters for contactless payments and accessories that require NFC. Connectivity also includes dual-band Wi-Fi, Bluetooth 5.2, USB Type-C 2.0, OTG, FM and location support for GPS, BeiDou, GLONASS, Galileo and QZSS. Check carrier coverage in your area and confirm the exact local box model if network compatibility is critical.

Android 15 and Funtouch OS 15

vivo Bangladesh lists Android 15 with Funtouch OS 15. The installed build and security-update date of the BiponiBD unit were not read from device settings. The local official specification lists a side-mounted capacitive fingerprint sensor, accelerometer, ambient-light sensor, e-compass, proximity sensor and ordinary vibration motor. These facts describe the manufacturer’s model data and do not establish an update-support period.

After delivery, review the system version, update status, language and installed services on the phone. Software releases and features may vary with region, carrier and production time. No promise is made about future major Android upgrades because an exact Y21d Bangladesh update schedule was not established. Buyers with work or finance apps should check compatibility on the actual software build.

Dimensions, weight and colors

The official dimensions are 166.14 × 77.01 × 8.39mm with a listed weight of 209g and composite plastic sheet back cover. vivo warns that measurements can vary with processes, materials, methods and production batches. Coral Red and Jade Green are the Bangladesh color names shown by vivo and Star Tech. The exact BiponiBD stock color was not verified when this copy was prepared.

At about 209g and 166mm tall, the Y21d is a sizeable handset. Compare it with a phone you already use to judge one-handed reach, pocket fit and grip. A color name or image on another retailer page does not establish BiponiBD inventory. Confirm the selected finish on the order and the sealed box, especially when the color is a deciding factor or a return condition applies.

Included items and package details

vivo’s Bangladesh e-store lists the phone, charger, USB cable, eject tool, warranty card, quick-start guide and phone case in the box. The official specifications also list an applied protective film. This is manufacturer package guidance, not a physical inspection of the BiponiBD shipment. Keep those items distinct from extras that a retailer might add as a promotional bundle.

Check the seller’s written order details for the exact package and any separately advertised accessories. At delivery, compare the box and invoice, retain packaging and inspect the cable, charger and case. If contents differ, raise it promptly under the stated seller policy. The product record previously used generic authenticity and warranty claims; those claims were removed because they did not establish this merchant order’s terms.

Bangladesh price, VAT and warranty

vivo Bangladesh lists BDT 26,999 plus VAT for the 6GB option, and its e-store shows BDT 26,999 with VAT applicable for Y21d 6GB+128GB. Star Tech currently shows the selected 6GB/128GB configuration at BDT 26,999. The catalog MSRP of BDT 26,999 is preserved as a reference. Third-party Bangladesh price trackers show variant-specific offers that change over time; they are observations, not a BiponiBD checkout offer.

The final BiponiBD payable amount, VAT treatment, discount, stock, delivery and return terms have not been confirmed. The catalog’s former one-year official warranty claim was based on retailer copy, not BiponiBD order documentation, and has been removed. Ask for the written warranty and service route that apply to this exact purchase. Keep the invoice and box for any later service request.

Pros and trade-offs

Specification-based positives include the T7225 processor, 6GB/128GB local option, 6500mAh typical battery, 44W charging, dedicated two-SIM plus microSD tray, stereo speakers and officially tested IP68/IP69 protection. These facts can help buyers shortlist the device for general 4G use. They do not establish an independent performance ranking, guarantee two-day battery life or remove the manufacturer’s liquid-ingress limitations.

Trade-offs include HD+ rather than Full HD resolution, 90Hz rather than higher refresh tiers, no NFC, a 4G-only connection and a relatively large 209g body. IP ratings require care and do not mean waterproof use. The 6GB configuration does not receive every 8GB-only dual-view mode. Compare these limits with your priorities and verify the exact option and checkout terms before paying.

Who may want the Y21d 6GB/128GB

The 6GB/128GB option may suit someone who wants a large HD+ display, a high-capacity nominal battery, dual-SIM plus microSD support and a Bangladesh-specified 4G device. The official vivo page and current e-store selection provide a clear local configuration and price basis. Compare it with alternatives using physical memory, storage type, screen sharpness, connectivity and written warranty rather than virtual RAM headline numbers.

If NFC payments, 5G, Full HD resolution or a lighter compact phone is essential, verify those needs before ordering. Users interested in the camera’s underwater photography mode should follow vivo’s separate warning not to immerse the phone during daily use. This product is mapped to 6GB/128GB; confirm the exact sealed unit and color on the order confirmation.

Before ordering and after delivery

Before ordering, confirm 6GB RAM, 128GB storage, the selected color, VAT-inclusive checkout total, included charger and accessories, stock, delivery time, return rules and written BiponiBD warranty. The box model should be the Bangladesh Y21d 4G configuration. Check vivo’s published LTE bands if a particular carrier band matters, and remember that NFC is not supported.

After delivery, compare the invoice, sealed-box label and device settings. Check the memory tier and included accessories during any permitted inspection period. Retain the invoice and packaging and report mismatches promptly. This guide summarizes official manufacturer information and attributed Bangladesh market observations. It does not independently certify IMEI, authenticity, condition, manufacturing batch, charger output or warranty entitlement for one physical device.
