Carrier Compatibility (USA / Global)

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

• USA: An unlocked unit can work on GSM‑based carriers such as T‑Mobile and AT&T if the phone’s supported LTE and 5G bands align with each carrier’s network frequency requirements (e.g., broad global 5G NR and LTE band support). Advanced features like VoLTE, Wi‑Fi Calling, and full 5G NR data depend on carrier certification and regional firmware, so check the exact supported bands with your carrier before purchasing.
• Global: With wide band support across 2G/3G/4G/5G, the phone also works on major carriers in Asia, Europe, Africa, the Middle East, and other regions when unlocked and bands match local networks.
