realme C21Y

The realme C21Y is an older entry-level 4G phone offering a large battery and basic cameras, but its software and performance are dated.

• Battery: The 5,000 mAh battery supports daily use and occasional reverse wired charging.
• Display: The 6.5-inch HD+ LCD provides ample viewing space for everyday browsing and videos.
• Camera: A 13MP main camera accompanies macro and monochrome lenses for basic photography.
• Storage: A dedicated microSD slot expands storage without replacing either of the SIM cards.

You can also buy a new smartphone on Easy EMIs at over 1.5 lakh partner stores across 4,000 cities, including Reliance Digital, Croma, and Vijay Sales.

The realme C21Y arrived in India in 2021 as an affordable smartphone for calls, messaging, basic photography, and media. It combines a 6.5-inch HD+ display, Unisoc T610 processor, 3GB or 4GB RAM, and a 5,000 mAh battery. A 13MP main camera is joined by macro and monochrome sensors, while the dedicated microSD slot is useful for photos and downloads. However, Android 11-based software, micro-USB charging, and limited performance make it less suitable for demanding apps today. Buyers should verify stock, warranty, battery condition, and update support before considering remaining inventory or refurbished units.

You can get a new smartphone without exhausting your savings. Visit any of Bajaj Finance's 1.5 lakh partner stores — like Vijay Sales, Croma, Reliance Digital, and more — across 4,000 cities, including Tier 2 cities like Jaipur, Lucknow, Kochi, Bhopal, and more in India. Choose your preferred model, then use the Bajaj Finance Insta EMI Card or Bajaj Finance Easy EMI Loan to finance it. Convert the cost into Easy EMIs that suit your monthly budget and enjoy zero down payment on select models — take it home without any upfront payment.

These common questions focus on everyday performance, camera quality, battery endurance, software support, and whether this model remains a practical purchase.

➜ Is the realme C21Y still suitable for everyday use?

It can manage calls, messaging, light browsing, and basic video streaming, particularly when storage is kept free. However, the Unisoc T610 and 3GB or 4GB RAM may struggle with demanding games or extensive multitasking. Older software support and uncertain new-stock availability make a current entry-level smartphone a more practical long-term choice.

➜ How good is the realme C21Y camera?

The 13MP main camera is intended for simple everyday photography in favourable lighting. The 2MP macro and 2MP monochrome sensors add limited creative options, while the 5MP front camera handles basic selfies and video calls. Expect modest low-light results and fewer stabilisation features than those found on newer budget smartphones.

➜ Does the realme C21Y support 5G and fast charging?

No, the realme C21Y is a 4G smartphone and uses a micro-USB charging port. It has a 5,000 mAh battery with reverse wired charging, but it does not provide the high-speed charging systems found on many newer phones. Consider newer alternatives if 5G connectivity or short charging times matter.

Bajaj Finance offers two financing options at over 1.5 lakh partner stores across 4,000 cities in India. Here is how they compare:

How to choose?

Both options require you to be physically present at a partner store. The Insta EMI Card is ideal for shoppers who want to purchase across multiple categories over time. The Easy EMI Loan suits buyers looking to finance a higher-value purchase in a single transaction.

Example:

Ananya, 29, Bengaluru, compares an older realme C21Y with a new eligible 4G smartphone costing Rs. 12,000 at a participating Reliance Digital store. With approval for a 12-month, zero-interest plan and zero down payment, the principal equals Rs. 1,000 per month. The actual EMI and total repayment depend on charges, offers, and eligibility; availability of the C21Y itself is not assumed.

The process is simple and typically takes 10 to 15 minutes once you are at the store.
