[Q] 920i vs 920f?

So does anyone know the difference between these two models? I live in the US using straight talk on AT&T's network. From what I can tell, they both should work, but I am not sure if there is any difference I should be aware of before buying the phone.

I have the G920i that I'm using on cricket (cricket uses att bands) and it works perfectly with LTE. I'm not sure about the 920F but I know that the f is the global unlocked version whereas the I is also unlocked but for selected regions.

How does it work in areas where LTE is not available, i.e. on 3G and HSPA networks? I live in an area where half my day is spent on the fringe of LTE service and the other half in.

Well just like US carrier phones, you'll get LTE signal when you get LTE signal and you'll fall to HSPA+ or 3g when that is the signal you get.

I'm asking more along the lines of can the phone receive the 3G bands in the area? I was wondering if the phone actually could receive what was being broadcast.

That I don't know. You gotta check the bands with your phone and carrier.

My G920I does on AT&T. I've seen it go all the way down to EDGE because I have really bad signal at my house.

I can also confirm that the 920i works fine on AT&T. I have seen it go from Edge to LTE and everything in between.

Does the International version support Wi-Fi calling and VolTE on T-Mobile?

I'm on T-Mobile, but I would rather buy the International version of the S7 to eliminate bloatware and to have the Exynos processor, not to mention the unlocked S7 is cheaper. However, I would like to use VolTE and Wi-Fi calling too. Will I have these features if I buy the international unlocked version?

I've never had any of my unlocked phones support WiFi calling or VoLTE, only T-Mobile branded phones did.

you will probably have to flash the t-mobile roms from your country (I guess states?!). If you get a exynos S7 and some t-mobile usa branded roms for that VoLTE and WiFiCalling shouldn't be a problem. Getting those roms for the SM-G930F might be your biggest problem.
-Acid

How readily will the roms be available? I remember doing it for my HTC One M7 a few times and it wasn't too bad.
I also thought some phones like the Nexus 6P supported VoLTE and Wi-Fi Calling on T-Mobile?

The intl version does not have band 12, wifi calling on TMO, or VoLTE support on TMO.
Don't do it.

Thanks.

oh yeah, and finally, heres the actual samsung product page

so, there it is...the g935 has band 12...unless samsung is wrong?

Man, those sites provide confusing answers because there's one g935f owner on this forum who has T-Mobile who said it doesn't support VoLTE and Wi-Fi calling.

That's because t mobile used to add their specific code to their phones' firmware. But now they're built into android so they may work.

When you state now they're built in, do you mean in Marshmallow?

I remember reading that's how the Nexus 6p gained the ability to use band 12 LTE support.
http://www.tmonews.com/2015/12/some...nd-12-lte-support-after-android-6-0-1-update/

Unbranded versions of the firmware do not support VOLTE for some inexplicable reason (the feature is there, just hidden), while some carriers do, they even use the same firmware with only a CSC change (like unbranded the XEF French unbranded firmware vs French Bouygues BOG firmware)
There is no T-mobile USA firmware for the Exynos/international variant but there are plenty of European carrier that handle VOLTE and have no branding, just flash the respective firmwares or CSC using ODIN (does not trip knox) which will enable the feature (you may need to perform a factory init to apply the CSC change)

I'm using the latest XEF firmware in my s6 intl 920F. Where do you get the csc to flash to enable these features?

That's for nexus devices, Samsung only enables WiFi calling on carrier branded ROM's.
If you buy the unlocked international version, you will not get VOLTE or WiFi calling. You will get band 12.

Isn't this the first Samsung phone that comes with marshmallow?
Before marshmallow, wifi calling had to be added by the carrier to their rom like t-mobile did on moto and samsung phones.
I don't know for sure, just speculating

Can anyone actually confirm who had the Intl version that volte doesn't work

I don't have the s7, but I did have the international note 5. When i received the marshmallow ota, a volte icon appeared in the quick toggles bar. When i tried to click it to turn volte on an error message popped saying that carrier is not supported. I tried both with a T-Mobile and at&t sim.
The s7 may be different, but I highly doubt it.

Exynos in the US?

Has anyone gotten an Exynos S7 to work in the US with any of our carriers?
I'm so desperate for a rooted S7 Edge that I'm ready to change carriers if I have to. :crying:

It probably will work but it won't work well, especially with T-Mobile (no band 12 or VoLTE). Just wait m8

I have been using g930s variant along with g930f kernel + roms in the us tmobile. I live in DC and LTE has been just fine. Maybe i am missing a band but whatever

I'm using the Exynos S7 on cricket and it works flawlessly. Performance is stellar, battery life is incredible and I get great LTE coverage everywhere.

How can you confirm that? I got the Exynos international version, with T-Mobile SIM card. I have AIDA64 but not sure where to look to confirm or deny that the LTE Band 12 is not there.

T-Mobile has to certify and allow the phone to work on band 12 or else it won't be able to make 911 calls. They've verified the US S7 but I don't think they verified the international version.

Hello there,
Well, I can confirm that LTE Discovery App shows the LTE Band 12 working with T-Mobile. I have walked around the building where I work, and it switches back and forth from Band 4 to Band 12.
Hope this helps someone asking if the Samsung Galaxy Exynos International Version SM-G930F works with T-Mobile LTE Band 12 !
Cheers,

it's frustrating that others have said recently that band 12 is NOT supported. what about wifi calling?

Hi there !
I belive that WIFI calling and the reduced Internet speed while on a phone call, are the two things that are different on the Exynos. Tell me how to check and make sure WiFi doea not work and I will try for you. I have tested the second one, and indeed the Internet speed is way reduced when talking on phone. Depending where you are, it is either H+ or 3G.
Hope that helps !

i believe there should be a setting for wifi calling within the "more connection settings". if it's not showing within the settings, then it's not supported.
as for band 12, how reliable is that app you used? a lot of people have mentioned that band 12 is not supported on the exynos model, so i'm really curious how yours has it.
thanks!

OK, there is no WiFi calling setting under there.
As for how reliable the App is, I have no idea, sorry. I searched and found it was mentioned in XDA for checking this kind of settings/capabilities. I will take a screen capture of it once I am in a building and it is showing the band used. My understanding is that LTE Band 12 is particularly good and improves signal inside buildings.

The Internattional version does support band 12. and it works, however for VoLTE you have to find a firmware that has it which is hard. the Czech t-mobile firmware has VoLTE but no WiFi calling

The "F" international version also has Band 17 for AT&T

why do people who DON'T have the phone act like they know what they are talking about.
Works fine on T-Mo, and ATT. you just miss out on some of the bands, and also carrier features like VoLTE.
my 930F works fine on Tmo. and it'll work fine on ATT as well.

Band 12 on Model SM-G955F?

I cannot get a definitive answer on this. When I check some sites it shows that this international model SM-G955F has band 12 which is what I need for Volte on T Mobile:
https://www.frequencycheck.com/models/G9Yo5/samsung-sm-g955f-galaxy-s8-plus-td-lte-samsung-dream-2
http://www.phonemore.com/phone/samsung-galaxy-s8-plus-sm-g955f/3234
But on the Amazon site to order the device it does not list Band 12.......
https://www.amazon.com/dp/B06XYKR7GP
Here is another posting of it and this list no bands....
https://www.amazon.com/Samsung-Galaxy-64GB-Unlocked-Phone/dp/B06XZRMCS7/ref=pd_sbs_107_1?_encoding=UTF8&pd_rd_i=B06Y15D6RP&pd_rd_r=S8FN2DDKWM54QN8JXJ6D&pd_rd_w=5nH47&pd_rd_wg=uVQ72&refRID=S8FN2DDKWM54QN8JXJ6D&th=1
SO, does anyone have this actual model and can actually check the LTE bands available on that model for me? I would greatly appreciate it before I spend that kind of money. I definitely want the Exynos unlocked for ROM, root, etc. If you are nopt sure how to check here is an app I found to check what 4G bands your phone supports...

The SM-G955F? Has band 12. If you plan on using it on T-Mobile you need to make sure it also supports VOLTE on their network.
I'll be getting mine next week and will try to confirm if it has VOLTE on T-Mobile.

According to the FCC listing it supports the following US bands 12, 17, 13, 26, 5, 66, 4, 25, 2, 41 so aside from band 30 it has all the bands needed to work great on AT&T and T-Mobile.
It also has carrier aggregation with US bands with the following combinations:
2+12
4+12
4+17
12+12
66+17
41+41
66+66
and 3 band carrier aggregation at the following bands:
4+12+12
66+12+66
41+41+41
Usually the FCC info is the most accurate!

*#2263#

Will like to know as well

I also looked the options.. this is what i understood..
amazon and other ebay list the International version of ASIA where Band 12 is not listed.. and no Region lock.. you can use any SIM on this..
EU version has Band 12 listed, but it has region lock enabled, so you need EU sim and get it activated by making call for 5 min. then you can put any SIM. but band 30 is not supported (ATT)
i enquired on Clove they listed Band 12 is supported.. whoever have the device can confirm on this.

Does Anyone from the Us have the Hk N980 Note 20 ultra?

Loooook long story short, I returned My US note 20 ultra once i found out it couldn’t be rooted, Ive been rooting phones for over 8 years now i cant stop now lol anyway I ordered The hong kong N980 edition and im just wondering how is the 4g signal in the US Especially considering that theres only gonna be only 3 bands available for my carrier.

4g is finebut 5g is non existent lol
Maybe because I'm on fi

Exactly the same experience.
Though I read elsewhere on this forum that 5g doesn't work on this device outside HK regardless of whether you are in a location with the right 5G bands.
I actually had an aTT 5g version but need dual sim. Got 5G everywhere (more like filling in dead zones gaps where I used to have no signal). It was great. If carriers enable esim like apple devices do on their networks I will switch back immediately, as the carrier models have 2 imeis
The other disadvantage is that these seem to get the slowest updates.

Yeah, The hongkong variant 5g Wont work in the us because Hongkong doesnt share the same 5g band The us do. But it does work in The uk and some parts of europe and ofcourse in hongkong. 4G is all i need personally but is the 4g fast for you?

Yes. But it could be that city centers are emptier because of covid

you need to downgrade to TGM version of the firmware using Odin and 5G will work again from the SIM2 slot only!
