Getting LTE on AT&T network with SM-G900F?

Is it possible? I mean both phones largely support the same bands and both use the same chipset.

I think it is possible but not so easy. All S5 branded have a lot of costumization about config and setting. Not just on kernel and system. I have G900L with same hardware of AT&T and g900F and i have try to flash a full stock g900f firmare and got brick.
Also flash custom rom brick the phone (it say can't boot in normal mode and bot always in download ODIN modem)
I also try change modem files phone work but not LTE
Maybe need flash all phone with Bootloader PIT/EFS and other partition not just kernel/System or need a custom Mod for fix some deep setting.
Actually with a sim 4g LTE but different carrier frequency i got every boot phone this message and is pretty annoyng

and if i try change manually 3g/LTE in network setting i miss menu voice at all

Sorry, can you explain how to change the modem files? and after it changes, the mobile network menu still displays a same option or added a new option? (like network mode, etc. as picture below)

Yes: your phone supports 4G/LTE
1. Do you have an U-SIM
2. Do you have 4G/LTE activated for your subscription
3. Do you have 4G/LTE coverage
4. Does your network support 4G/LTE

有難うございます．日本人の方ですよね．
どうやってＬＴＥバンドを切り替えますか？自分は402ＳＯを買って，ドコモのRomを焼いて使おうと思いましたが，成功できません．
そこで，AuのRomを焼いて，LTEバンドを切り替えれば良いと思いました．ですが，前代の401SOのようにできません．

Meizu Metal 3G and 4G connectivity not working

Hi Everybody,
I have bought Meizu Metal from Aliexpress and received it few days ago. Everything is working smoothly except the 3G and 4G connection. The system version is Flyme OS 5.1.2.0Y, YounOS version 3.1.6. The GSM network is working fine. The specifications of the phone clearly shows that it supports 3G and 4G networks : 4G FDD-LTE:Bands:B3,B1 , 3G WCDMA:900/1900/2100MHz. My local operators supports 2100mhz for 3G and B3 for 4G. The phone detects 3G and 4G connection , but when I try to start browser or any app that requires internet it fails to connect.

Have you set APN values? If you haven't, find out those values with your carrier.

Thank you. That was the problem. I set the APN values manually and it worked

[SM-G900F] Connected to GSM/WCDMA but it shows the "4G" icon

Hi everyone!
3 years ago, I purchased the Galaxy S5 (SM-G900F orignal) from Mobicom (Mongolia). The phone has the 4G LTE capability but it has some problems
1) I have a 4G LTE SIM card and a contract (and i'm near 4G LTE towers) but it doesn't connect to.
2)I set the network mode to GSM/WCDMA/LTE (auto connect) but still not showing LTE.
3) "Network type" shows EDGE/UMTS/HSPA not LTE, but my display shows 4G (confusing)
Is there any problems with my phone itself? How i can fix that?
Here is my screenshot:
