International vs ATT version lumia 1520

AT&T version doesn't support qi(wireless) charging. Also(although this may have changed)no 32GB version.
 
The bands are different:

3G Network Global and AT&T: 0HSDPA 850 / 900 / 1900 / 2100
4G Network Glbal: LTE 800 / 900 / 1800 / 2100 / 2600
AT&T: LTE 700 / 850 / 1700 / 1900 / 2100 / 2600
 
Int'l is 32 GB
ATT initially had a Qi-less 16 GB model, but soon got a 32 GB model. Still no Qi.

And of course band differences.
 
There are band differences, but 1520.3 RM-938 is perfectly compatible with the AT&T network at all data speeds up to and including LTE.

Internal storage is usually 16GB from AT&T or the 32GB at a premium and ONLY in black.

Wireless Qi charging is built into the 1520.3 and requires no additional case or jacket. AT&T uses a special case to wirelessly charge on a PowerMat standard.

There are several "international variants" of the 1520. The 1520.3 or RM-938 is the one you want for US use and it was made Factory Unlocked for Latin America, comes in several colors and all with 32GB. The 1520.1 or RM-937 was made for Europe and has the wrong LTE Classes for US compatibility. The 1520.4 or RM-939 is made for China and has no LTE radio.
 
AT&T one (RM-940) with Cyan will almost certainly not tether on T-Mobile.
1520.3 (RM-938) does tether successfully on T-Mobile.
