Unlocked ATT On Tmobile

yes, you will get lte on tmobile, and 4g. just go to a corporate tmobile store and the will supply you with the latest sim card.
 
Yes. I have an unlocked lumia 1520 AT&T Varient. I was able to get a hold of a friend's tmobile sim card and I can confirm that I was able to make and receive calls, send and receive texts, browse the web with LTE, and etc.

You will get LTE alright on T-Mobile, but you won't get 3G. RM-940 doesn't have the band 4 on WCDMA. So, you will be dropping from LTE straight to 2G, of course, depending on your coverage. Only RM-938 has band 4 support on WCDMA.
 
^^ in addition to that, the AT&T variant does support HSPA+ in T-Mobile in places where T-Mobile has refarmed it's frequencies to 1900MHz, where it hasn't it'll only get 2G

Not quite correct. I have an RM-940 unlocked that I use on T-Mobile. You get LTE, 4G and then drop down to Edge. (4G is only HSPA+21 vice HSPA+42, assuming the towers have been refarmed. I believe T-Mo has said they are nearly done regarding too or will be done by the end of this year, so everyone should be covered.)
 
If unlocked att gets lte on tmobile , guess only difference between this and 1520.3 is that it has qi wireless and 32 GB right ?
 
Well att version doesn't have aws ,hopefully I have no issues with service on t-mobile

Do you have any link to support that? Because from my personal experience (and I'm RF person, so I pay attention on these things wherever I travel) they have not re-farmed much (OK, MO, IL, IN, OH)
