Can I pair Amazfit T-REX with an account which has already paired with Amazfit watch?

Yes, you can pair Amazfit T-REX with an account that you have already used to pair other models.

But you can’t connect them at the same time. One of them can be an active device and connected with your mobile phone and the other one will disconnect.

Note: You can’t pair two Amazfit T-REX in one account at the same time.
