Carrier Compatibility (USA / Global)

The Xiaomi Redmi K90 supports GSM / HSPA / LTE and 5G (SA/NSA) network technologies with dual Nano‑SIM:

Advanced carrier features like VoLTE, Wi‑Fi Calling, and full 5G NR support depend on carrier certification and regional firmware — it’s recommended to verify exact supported bands with your carrier before buying.
• Global: With broad LTE and 5G band support typical of modern smartphones, Redmi K90 can operate on carriers across Asia, Europe, Africa, the Middle East, and other regions when unlocked and frequency bands align with local networks.
