T-Mobile is continuing its "Un-carrier Unwrapped" holiday initiative, this time with a couple of offers for AT&T customers. For a limited time, customers switching from AT&T to T-Mobile can get up to 50 percent, or up to $125, off items like speakers and headphones, chargers, fitness trackers, and even smartwatches.

These offers are open to all AT&T customers, including post-paid, GoPhone users, along with those using AT&T's Cricket pre-paid brand. When you switch, T-Mobile will pay up to $650 per line in early termination fees, or the balance owed on your AT&T phone.

This deal kicks off on Friday, December 4, and will run through Sunday, December 13.
