Note5 android update on AT&T phone on T-Mobile network

[AC Question]

Bought an Unlocked AT&T Note 5. Had it put on my T-mobile network. Has Android 6.0 need to update to 7.0. Can I just use the software update or is there a need for an AT&T sim card?

Welcome to Android Central! I believe you'll need to be on AT&T's network to get the update (even if using Smart Switch).
