phones like the nexus 5?


One of the features of nexus 5 that I like is the ability to have a phone that has all the bands for AT&T and Tmobile built in so it can be fully used on either. I have been reading that just becasue you unlock a phone it does not necessarily mean it will work on the LTE or 4G networks for both providers. Are there any other phones (like the nexus 5) that offer this? Thank you.
