Will a Tmobile Note 2 work on AT&T? Verizon?

[AC Question]

I have a decommissioned Note 2 (broken screen) that I was thinking of reviving and using on AT&T. Maybe Verizon. Can I?

I should work on AT&T, but not Verizon. T-Mobile phones are GSM only, while Verizon phones are CDMA (for voice) and GSM for LTE (for data). Verizon now has Voice Over LTE, but only more recent phones can take advantage of that. Your Note 2 most likely can't.
