How to Decide Between a Carrier-Locked or Unlocked Xiaomi / Redmi Phone

Most Xiaomi phones sold outside of North America are already SIM-unlocked. In markets where carriers do sell locked Xiaomi devices, here's what you need to know.

Key Differences

When to Choose Carrier-Locked

• You already use that carrier and plan to stay for 1–2 years.
• The monthly payment plan makes a $600 phone affordable at $25/month.
• The carrier offer includes perks (free streaming service, extra data).

When to Choose Unlocked

• You travel internationally regularly.
• You want to switch carriers for better deals.
• You prefer receiving Xiaomi software updates immediately without carrier delays.
• You want the highest resale value.

How to Check If Your Xiaomi Is Locked

1. Insert a SIM from a different carrier.
2. If the phone asks for an unlock code or shows "SIM not supported," it's locked.
3. If it connects normally, it's unlocked.

How to Unlock a Carrier-Locked Xiaomi

1. Contact your carrier after completing the contract period.
2. Request an unlock code (usually free after contract end).
3. Enter the unlock code when prompted with a new SIM inserted.
4. Some carriers unlock remotely via account settings.
