I am not sure of the frequency differences between AT&T/T-Mobile and 521/520. I want to unlock my 521 and put in my AT&T SIM card and use this phone as my daily driver for a while. Will I be able to make calls without issues (are the cell frequencies compatible)? Also what kind of data speeds can you expect with an AT&T SIM on the 521?

It Supports AT&T 3g/4g HSPA Bands and should work fine on AT&T if you can get it unlocked.T-Mobile Lumia 435 Firm (Denim) OS ver (GDR2)

Sightings of T-Mobile 3G/4G/HSPA+ coverage on 1900MHz (PCS/UMTS band II)
So if you live in a major city, you are in luck.
The speed imo is enough for me. When I use friends VZW LTE phones, I notice a difference but its meh to me... since im on wifi 97% of the time.
Ironically, EDGE isnt that slow for me either if you use Opera Mini/Nokia Xpress Browser for simple things.
