Design and Build
The design of the vivo Y21a is straightforward and practical with a contemporary touch. The phone measures 164.3 x 76.1 x 8 mm, making it reasonably compact and comfortable to hold. Weighing 182 grams, it feels solid yet not overly heavy. The device features a glass front with a plastic frame and back, which is common in this price category, providing durability without making it too fragile. The dual SIM capability is a plus for users who need to manage multiple lines efficiently.
