Ensure Bluetooth is on, the band is awake, and Mi Fitness has Bluetooth/location permission. Close other Bluetooth apps and try again.

Can I pair the band with two phones at once?

Usually no; unpair from the first phone before pairing with a second.

What to do if pairing keeps failing?

Charge the band, toggle Bluetooth on your phone, grant permissions, and if needed perform a factory reset then try pairing again.
