Being that the 2 carrier's are GSM network's the band in each device are really similar right? Will I be able to get 4G LTE on my unlocked At&t Samsung Galaxy s9 plus running it on t-mobile's network. Thanks In advance!!!

There is no more att hardware and T-Mobile hardware everything is same and the phone will have every band. Hardware wise you are set. Software wise you probably need to flash unlocked or tmobile firmware to enable bands needed. This flashing doesn't void your warranty. There should be multiple threads in xda describing process to flash and links to firmware.
Is there other way to use or activate 5g on my samsung s21 us variant here in philippines?

You have 5G in the Philippines? Assuming you do, then there are 2 protocols used with 5G, pretty sure the US version phone isn't compatible with international, but could be wrong on that.
but if you're carrier doesn't have it, it will never work

Follow this link for the S21 specs on gsmarena.
The important part to look at is the Neworking 5G bands. You'll see that the US phone u have uses mmwave technology for 5G. And that the international version, the SM-G991B uses Sub6. They are not interchangeable.
Sorry, after looking at this closer, the US version does actually do both MMWave and Sub6, but still won't help you as it doesn't have band 78. And, unfortunately, you can't flash a rom for one of the other devices to yours, as they have different chipsets; exynos vs Qualcomm.
Does anyone have an authoritative link or source for the different S23 ultra regional model variants and their respective bandwidth frequencies such as for 4g and 5g?
Can't find this information for any including the USA variant eg which specific frequencies of 4g and 5g does the USA model support?
The chipset and x70 modem makes it possible for this phone to truly be a global phone but.....
asking the same as well, cant find these details.
Here's hoping that the band unlock methods for the s22's and s21's also work on the s23's.

I'm sure it will be the same to unlock the bands, no one will really know until they have one in hand.
Can you elaborate on these band unlock methods?
And could they unlock mmwave for example on the international variants so that 5g could work in US? And unlock international bands on US version so it could work everywhere else?

This is the thread you probably want to have a look at. This method also worked for the s21's.
How to Enable All Bands Through Service Menu on US/CA S22 series (including Sub-6 and mmWave)
What is this? This is a guide on how to enable all LTE and 5G bands on the US or Canadian S22 series phones by going through the service menu. This guide is mostly based on this S20U guide by mellojosh, but has been adapted for the S22U phone...

Interesting....
So basically you could enter the service menu and turn on all the extra bands?
In that case wouldn't the US version be the best one to have since it would have mmwave hardware baked in too? It should then work everywhere.
Though it sounds like you'll lose the function on os updates and resets?

OS updates from Samsung are never fast. Doing so once every 2 to 3 months isn't so bad for the extra band support.
Samsung's modem software works well for the US and Canada because the hardware is the same and only the modem software separates the bands based on carrier/region. Due to the wide spread of mess across North America, US and Canadian models are always a good choice for potential band support. In some cases though, mixed ROM's can also bridge the support. In the S9 days, you could.jeep.the base.for.your region but flash the carrier side of the firmware to unlock band 71 on some overseas models. I don't know if this is still possible today but with all devices being very similar. I am hoping the hardware, including dual-SIM pins on the main board, will be there to enable through a firmware change or mod.
Do we know if the international dual sim variant has the same USA hardware based on s22/21/20?
Does it have mmwave baked in but just disabled by software?
I am still not clear what 5G bands are supported on the SM-S918BZKPEUB, nor if unlocking the bands through the service menu works. @UK S23, your deliveries are in place already, has anyone tried?
It seems as though the bands might only be disabled in software? If so, then it should be possible to enable whatever band you need. The only exception would be if a hardware component is needed or missing then it wouldn't be possible which likely wouldn't be the case for your 3g, 4g and 5g standard range. Maybe only 5g mmwave which is essentially only in US anyway.
If that's the case it sounds like US variant might be the best to get for global coverage barring lack of dual sim (though it does have physical+esim).

Samsung's band support is mostly software, at least when it comes to 4G and 5G. I have never bothered to change 2G and 3G bands because there is no use for them unless you are in a very rural area or roaming. This is why it is so easy to convert the North American models and why in the days of the S9+, you could get band 71 on international models with dual-SIM.

Correct me if I'm wrong but you can't get mmwave bands on the international dual sim models right?

I'm not sure when it comes to mmWave. You can enable it on the W for Canada even though the cell coverage and technologies used up there are probably never going to deploy it. Overseas, I have no idea.

I've read that the US and CA models are basically identical so that might explain it. It's also possible I suppose that in s23 since it uses x70 modem, which has native support built in, that all model variants might be able to do it but for software. Though we won't know for sure till someone from different region goes into their service menu and checks.
mmWave requires a specific antenna to function. This antenna used to cost like $50 but I'd be surprised if it's gone down much beyond $30 so manufacturers will still leave it out if it's not necessary.

Thanks and that probably means it likely won't be in other region variants.
Personally, I'd just make a single phone that is globally universal and can be used everywhere. The massive scale should drop the component pricing considerably. Carrier exclusives and market restrictions if any needed in software only. But that's just me lol.

Yes, you would think they would do this, but Samsung has always customized difference models for different regions so it must not be that straightforward. I believe that regulatory bodies would require them to test and submit all the documentation for that extra antenna, for example. It also wouldn't surprise me if the mmWave equipment is outright banned in some regions either for whatever reason.

No. There are 5 different models of iPhone 14 Pro Max, for example, and each will have different band configurations.
That said, the NA models have the most complete bands of any device released so far this year and it was released last year with an older modem. They even have support for Dish Network's n70, a band exclusive to them worldwide, something Samsung didn't even choose to support on their NA variant this year despite having a contract with Dish for radio equipment supporting that band.
I actually think the NA iPhone 14 Pro models support every commercially available band worldwide but I don't really keep up on bands not used in the US.

I have an SM-S918B)
While I get 5g in the states, some bands are a little different so I fall back to 4g more often.
Is it possible to put a US firmware on the SM-S198B and get the US bands? I believe the hardware is the same.
I'd appreciate any education!
No you can't flash the International model with the US firmware, they are different hardware ,different motherboard and antennas , but i think T mobile supports the International version very well

It does once I enabled all the bands. But it's missing 71 which is what most of the T-Mobile 5G is Las Vegas uses.
Does anyone have this variant running on verizon? If so how does it work?
You can always check the bands that model supports vs the bands for Verizon in the area you plan on using it. Both sets of information are available online. Cell mapper I believe is the app you see what bands and networks are in your area and GSMArena should have the bands listed for that model.
I have looked and 4g has all the bands 5g is missing the mmv ones but can't find anything on 3g for either one.

I looked it up and yeah the only models that support us 5g mmw is U/U1 models so no 5g and likely 3g isn't supported on models that are outside us is my guess.
