The vivo Y31d is a 4G phone in the cited regional listings, with a 6.75-inch LCD, a 7,200 mAh typical-capacity battery and a 50 MP main rear camera in the Mexico configuration. Its specifications are not identical in every market: memory options, cellular bands and even the way water-resistance ratings are listed vary by country. Treat the Mexico specifications below as one clearly identified example, and check vivo’s page for your country before choosing a variant or deciding whether it will work with your carrier.

Are all vivo Y31d versions the same?
No. Official vivo pages show different RAM and storage combinations by market, and the cellular-band lists are country-specific. The listed protection ratings also differ, so a rating shown on one country’s page should not be generalized to every Y31d.

Check carrier compatibility before buying
The Mexico and Nigeria listings identify the phone as a 4G model and state that 5G is not supported. Their listed network bands differ. A SIM that fits the dual nano-SIM tray does not by itself confirm that the phone supports the bands your carrier uses. Check the exact local model and its band list against your carrier’s requirements.
Battery capacity and charging
For the Mexico listing, vivo specifies a 7200 mAh typical battery capacity and a 7060 mAh rated capacity. These are two different manufacturer specifications, not competing measurements. The phone supports charging up to 44 W FlashCharge; the Mexico page says a standard vivo charger is included and supports FlashCharge up to 44 W.

vivo also promotes battery-life and endurance figures, including a “6-year” battery-life claim and usage-duration claims. These are manufacturer claims based on design parameters and controlled testing, not independent measurements of every owner’s experience. The Bangladesh overview says results can vary with software, environment, model and user habits. See vivo’s Bangladesh product overview and Bangladesh specifications for its qualifications.

The Mexico configuration has a 6.75-inch LCD with a resolution of 1570 × 720 pixels, or 256 pixels per inch. Its listed refresh rate is up to 120 Hz, which can make supported motion appear smoother than on a standard 60 Hz screen. “Up to” matters: vivo notes that 120 Hz does not apply in every situation. The same page lists 1250 nits HBM brightness and 83% NTSC color coverage.

The resolution is HD+ rather than Full HD. If you prioritize fine detail for small text or high-resolution video, compare the screen’s resolution as well as its size and refresh rate.
Camera specifications
The Mexico listing gives the Y31d a 50 MP f/2.0 main rear camera, a 2 MP f/2.4 secondary rear camera and an 8 MP f/2.05 front camera. Megapixel counts describe image dimensions; they do not establish overall photo quality. The available specifications do not provide independent camera-test results, so they cannot show how the phone performs in low light, motion, portrait shots or video.
Rank #4

Water and dust resistance: understand the ratings
vivo lists IP68 and IP69 for the Mexico configuration and describes laboratory testing under IEC 60529-2013 conditions. The company cautions that the Y31d is not a professional waterproof phone and that resistance can decline through everyday wear. An ingress-protection rating is not a guarantee against damage in every liquid, depth, duration or real-world situation; do not treat “waterproof” as a description of the phone.
Regional listings do not present a single universal rating: the Belarus page also lists IP69+. Use the rating and qualifications on the page for the specific market and model you are considering. Sources: Mexico specifications and Belarus specifications.

Memory, storage and connectivity details
The Mexico version pairs 6 GB of LPDDR4X RAM with 256 GB of UFS 2.2 storage. vivo says extended RAM is software-based, so it should not be confused with additional physical RAM. The Mexico page says ROM is not expandable.
For Mexico, the listed connections include dual nano-SIM, 2.4/5 GHz Wi-Fi, Bluetooth 5.1, USB 2.0 Type-C and an infrared port. NFC is not supported on that listing. Cellular bands are market-specific; consult the relevant country page rather than relying on a band list copied from another region.
What comes in the Mexico box?
The Mexico package listing includes a quick-start guide, USB cable, charger, SIM eject tool, phone case, protective film applied to the phone and warranty card. Box contents can vary by market or retailer, so check the package details for the exact version you are buying. Source: vivo México specifications.

What to verify before choosing a Y31d
- Country and exact variant: confirm the RAM/storage option on the official page for your market.
- Carrier bands: compare the local model’s 4G bands with your carrier; the cited listings do not support 5G.
- Screen needs: weigh the large 6.75-inch, up-to-120-Hz LCD against its 1570 × 720 resolution.
- Protection expectations: read the regional IP rating and its limitations; resistance is not permanent or a promise of damage-free submersion.
- Included items: confirm charger and accessory contents with the local seller, since the Mexico package is not proof of every region’s box contents.
