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.

This is brilliant. Thanks! Have been trying to find a complete, intelligible list for a few days now. Should have started at XDA of course ...
Small correction: XEH stands for Hungarian unlocked only, Vodafone, Telenor and T-Mobile all have their own CSC codes (VDH, PAN and TMH, respectively - PAN because Telenor used to be Pannon GSM Hungary).
Am i correct that in the US, the carrier variants and even the unlocked version are all identical hardware with the same bands supported and it's just the software is different?

Yeah, I saw the carrier switching guide. I was just confused as someone mentioned that the hardware was all the same so the band support is the same except the carrier might have their own bloatware but the page below seems to indicate that the unlocked US and US Carriers is different when it came to band support. Can I get the Verizon version and have all the bands enabled or do I have to get the unlocked US version?

Well actually, Samsung locked everyone out so it doesn't really matter which variant you have, both the N950U (carrier variants) and N950U1 (unlocked variants) have locked bootloaders.
All of them should work fine outside the US when roaming, wouldn't really recommend it if you live outside the US though.
Yeah, I meant I thought some bootloaders would become unlocked later, I just know the Verizon one never seems to get unlocked compared to T-Mobile for example even with other brands of phones. If I had a choice, I would get the 128GB model which is available outside the U.S. except I don't know if it supports all the U.S. bands. Just wished Samsung was like Apple when it came to band support like the unlocked SIM free which seems to have support for all bands except for Japan when it came to 4G LTE as without the proper support, it will roam but be in 3G for data instead of 4G. With that said, just looked at the chart you provided and it seems like the SM-N9500 would be ideal for the 128GB or 256GB internal storage except it is missing the following bands which is on the US models:
3G (UMTS/HSPA): 1700
4G (LTE): B13, B17, B18, B29, B30, B66, B252, B255
So it seems it is actually the US model that has more band support while the China model has more internal storage.

That is correct. Chinese variant and Korean variants have the most storage options while the rest of the world is left with 64GB only.

I am thinking of getting an S21 from AT&T because of the deal they have right now, but I don't like AT&T bloatware. I'm a noob when it comes to phone firmware and such, so I'm not sure what is or isn't possible.
My understanding is as follows:
Carrier unlock is possible via AT&T website to use other carrier SIM cards.
Bootloader unlock is not possible on AT&T devices (starting at V2 seemingly?).
I'm just not clear if you need an unlocked bootloader to flash the stock S21 ROM on an AT&T device. If not needed, what is the point of unlocking the bootloader, just for root?
Any clarity is appreciated.
You can use "patched ODIN" to do flash "U1" firmware, which removes bloatware.
Not sure about the bootloader, I think you're correct on that.
I flashed an Xfinity Mobile S21 (carrier unlocked by them) to U1 but so far the phone is refusing to use the proper carrier settings for VoWIFI (I have a VZW sim in it now). It worked for 1-2 weeks previously. Everything else seems to work properly including VoLTE.
I'll probably switch back to Xfnity Mobile to get VoWIFI working again.
Thanks for the response.
can I ask something related? I got my Samsung S21 from Amazon unlocked and I'm in International market. the phone has esim capability but it's locked up. my question is (can) I flash international firmware or let's say the one being sold in the middle east? I'm stuck with single sim which is pretty annoying. what do you guys recommend

My understanding is that the international firmware is not compatible with the US phones because the US version uses the Qualcomm Snapdragon processor, whereas the international phones use the Exynos chip. I think you're stick with single SIM, unfortunately.

Hello , can I ask a related question, I've an unlocked s21 5g with the Three carriers SM-G991B .. Can I install the global version ??
I have one unlocked Samsung G21+ International version under T-Mobile that doesn't connect to their 5G network. Is this a limitation in the phone? How can I check compatibility with their 5G?

I think if you look at specs from gsmarena, you can see the 5g bands your variant is capable of. Assuming t-mo uses the sub6 technology, then just check which bands they use, if there's a match, it should work.
But, if t-mo uses mmwave exclusively, your device doesn't have that ability.
Should be pretty easy to find that info with google.
Yes, I did and unfortunately the frequencies from T-Mobile is not in G996B/DS .

No. Definitely not with T-Mobile or AT&T, don't know about Verizon.
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?

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.

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.

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.
