SM-N920C vs SM-N920I

Although I've read through more than a 100 posts, I still wonder if there is any major or significant difference between the two models...
Specifically, I'm debating if the N920I can work smoothly in a network where the official sold device is the N920C ? Is there any foreseen performance degradation or incompatibility issues ?
Many Thanks.

Hello
I believe there is no differences.
I'm using 920i in Brazil, where the C model seems to be the official one. The phone is working great and smoothly.

N920I LTE bands:
B1 (2100MHz), B2 (1900MHz), B3 (1800MHz), B4 (AWS), B5 (850MHz), B7 (2600MHz), B8 (900MHz), B12 (700MHz), B17 (700MHz), B18 (800 MHz), B19 (800 MHz), B26 (800 MHz), B28 (700MHz)
N920C LTE bands:
B1 (2100MHz), B2 (1900MHz), B3 (1800MHz), B4 (AWS) B5 (850MHz), B7 (2600MHz), B8 (900MHz), B12 (700MHz), B17 (700MHz), B18 (800MHz) B19 (800MHz), B20 (800MHz), B26 (800MHz)

OTA support
Sir are you getting OTA updates in Brazil?

Correct frequency bands support in X526 (indian Le 2)

Hi,
As Lemall india is already dead, I don't find any reliable source to confirm what are the frequency bands supported by my Le 2.
As per flipkart:
GSM - 850, 900, 1800, 1900 (2/3/5/8);
WCDMA - 850, 900, 1900, 2100 (1/2/4??/5/8);
4G LTE (FDD) - 1/2/3/4/5/7/8/20,
LTE (TDD) - 38/40/41
Now, lets check on frequencycheck.com
GSM : 850, 900, 1800, 1900
UMTS: B1 (2100), B2 (1900), B5 (850), B8 (900), B34 (2000), B39 (1900)
LTE:
B1 (2100)
B3 (1800 +)
B7 (2600)
B38 (TD 2600)
B39 (TD 1900 +)
B40 (TD 2300)
B41 (TD 2500)
The data on different sites varies a lot..
I am planning to go US and wanted to check what bands are supported by Le 2?
Help will be appreciated.
Regards

I have x520 .

Thanks. I will check my box. Hope the information on it is correct.

The box for my phone suggests flipkart is right

What ATT bands are missing?

According to Z3 Play page it has bands
LTE:††† B1 (2100) B2 (1900) B3 (1800) B4 (1700/2100) B5 (850) B7 (2600) B8 (900) B12 (lower700 abc) B13 (upper700) B14 (700 PS) B17 (lower700 bc) B18 (Japan low850) B19 (Japan hi850) B20 (800 DD) B25 (1900+) B26 (850+) B28 (700 APT) B29 (lower700 de) B30 (2300) B38 (TD2600) B40 (TD2300) B41 (TD2500) B41 HPUE (TD2500) B66 (AWS3+4) B71 (600 US)
UMTS:††† B1 (2100) B2 (1900) B4 (1700/2100) B5 (850) B8 (900)
CDMA:††† BC0 (850) BC1 (1900) BC10 (850+)
GSM:††† B2 (1900) B3 (1800) B5 (850) B8 (900)
It appears that this is all the necessary bands. According to ATT you need:
**MAIN BAND
12 –700 MHz Lower B/C/A. This is a superset of band 17, so band 17 is not required if band 12 is available in the phone.
**ADDITIONAL CAPACITY
2 – 1900 MHz PCS, provides bandwidth in many markets; 25 is a superset of band 2 but 25 is not required for some reason
4 – 1700/2100 MHz AWS, provides bandwidth in many markets
5 – 850 MHz CLR, the main band for areas lacking 700 lower B and/or C blocks
29 – 700 MHz Lower D/E – supplemental downlink bandwidth only; implemented in key markets
30 – 2300 MHz WCS, provides additional bandwidth in many markets
So it appears it has all of these,
HOWEVER, according to Motorola's carrier compatibility page it does not have a solid check mark next to ATT. Stating "Device is compatible with service provider’s network but some service provider specific features may not be available. Please contact your service provider for details".
SO MY QUESTION IS -
What is it missing???
*I'd post source links but XDA doesn't allow newbies to post links.

Perhaps wireless calling. The phone might be compatible to handle wireless calls, but I know AT&T is infamous for turning features off unless you buy the phones from them.

Most likely two things, Wifi Calling and VOLTE. AT&T blocks these features on all unlocked phones that I've had so far.

I'm not sure about available bands, but I've been getting blazing fast download speeds in off peak hours (83MBps), and reasonable speeds at other times. Just got my z3 Play today, and love it so far.

Update! Volte or HD Voice does in fact work on At&t. You have to either call At&t or go online if you have a business account and change the IMEI to an At&t phone. I can confirm that Volte works once you change the IMEI.

Update: Volte wors on Cricket Wireless too!

Hi, I assume you have the phone. How long ago did you you set it up ? Meaning, did it at any point reversed VoLTE connectivity and defaulted back to HSPA only? I've seen some people making it work on other phones (after the IMEI trick) but as soon system recognizes - reads the right IMEI, the function is gone.
Thanks

So I first just swapped the Sim from my Note 8 and Volte was working. After a few calls it went back to HSPA during calls. A few days later I manually entered the IMEI in Premier and it stuck. That was over a week ago, and a million calls later. I'm still on Volte when making calls. Some calls even have a little HD symbol next to the call time to let me know I'm experiencing an HD Voice call.

That's interesting to hear. The problem is that I don't have that option to manually change IMEI, because my account is not Premier or Business. When you say Premier, can you clarify if that's just another name for business or something else? I have all things ATT - TV, internet and wireless, so I'm wondering if I can get some special treatment too.
Also, I don't have the phone neither, so not sure if it would work on OG ZPlay or Z2 Play. Definitely would. love to try it. when I tried with the Customer Rep changing IMEI for me I didn't work on any of the phones I mentioned.

Yes Premier is their business account portal. You should be able to use the IMEI from another at&t phone and call customer care as well. As long as they choose the right plan, Volte should work. Not sure about the OG ZPlay, I feel like I tried it before and it didn't work with that phone. Never had the Z2 Play so I can't speak to that phone. Tried to upload a picture of it but my phone won't cooperate right now.

Thanks a lot for the input!
Just tried with Z2 play and submitted the IMEI over the phone (for Z2 force ATT edition) and it didn't work not even for a second. I guess I gotta wait out a bit for the price to drop and have Motorola release more colors for Z3 play

4G/LT4-signal

How about 4G/LTE-signal on this phone?
Phone should work on these bandwiths:
B1 (2100)
B2 (1900)
B3 (1800)
B4 (1700/2100 AWS 1)
B5 (850)
B7 (2600)
B8 (900)
B12 (700)
B17 (700)
B18 (800)
B19 (800)
B20 (800)
B26 (850)
B28 (700)
B34 (TDD 2100)
B38 (TDD 2600)
B39 (TDD 1900)
B40 (TDD 2300)
B41 (TDD 2500)
In my country we use B3, B7 and B20. I currently have Pocophone F1 and it's LTE should work in those bandwiths but it doesn't.
Lots of problems all over Europe with LTE.

4g works fine in Ireland on EU model, but signal is sometimes weak but likely down to my provider

I live in Italy (B20) and I've never had a single signal problem. Never had any connection loss or weak signal (maybe a little lower but because of operator, but no calls or internet problems).

Even my current Pocophone should work here in Finland but it doesn't. And that's a bummer because I pay for 100 Mb network and all I get is 20.

General Samsung Galaxy S23 -- different models (SM-S911x) (B/U/W/N/0/E)

When new phones are released, I always find this confusing, and have difficulty tracking down accurate information. Perhaps writing it down here, and getting feedback from the community, can help some other people:
GSMArena reports the following models:
SM-S911B
SM-S911B/DS
SM-S911U
SM-S911U1
SM-S911W
SM-S911N
SM-S9110
SM-S911E
SM-S911E/DS
source: https://www.gsmarena.com/samsung_galaxy_s23-12082.php
Typically there are lists suggesting which model corresponds to which geographic market. I'll work to track that info down, and add it here.

Looking through the firmware listings on sammobile (and Kimovi for S911E) here are approximate geographic regions for models:
SM-S911B -- Europe / Africa / Middle East / Oceania
SM-S911B/DS -- (assumed same as above, Dual SIM)
SM-S911U -- USA
SM-S911U1 -- USA ( factory unlocked )
SM-S911W -- Canada
SM-S911N -- Korea
SM-S9110 -- China / Taiwan / Hong Kong
SM-S911E -- Latin America
SM-S911E/DS -- (assumed same as above, Dual SIM)

additional updates

Another thing I've tried to track down in the past is radio bands / frequencies.
Kimovil seems to have dedicated pages for five various models (which means it covers 8 of the 9 models from the OP list), so I'm posting them here.

Wow. I just realized that S23 has no Exynos models anymore. Has the Samsung gods answered our prayers to finally bring bootloader unlocking to Snapdragons or will it stay locked?

@webhook Right?!?! If I'm understanding correctly, this XDA article says:
... the bootloader of the US and Canadian Snapdragon models can't be unlocked, a design which essentially forced most of the modding jobs centered around the Exynos-powered editions. This changes with the Galaxy S23 series, as all regional variants are now powered by a modified Snapdragon 8 Gen 2 chipset.

Sounds like our prayers have indeed been answered!
And I think this post by @afaneh92 shows that's right :-D In fact, they have several examples of custom recoveries running on S23 models.
The reason I'd started this tread was becausefor the S22 I had all kinds of hassles trying to weigh which variant was the right choice; the US models couldn't be unlocked, but the international ones didn't have quite all the right radio bands/frequencies. I never ended up buying the S22 because of it.
Seems like that's all a thing of the past.

On another thread, someone else has indicated it's possible we may be celebrating too early. Apparently it is possible that, Sammy used a uniform chipset, and still went out of their way to create extra bootloader locks for specific region variants.
I pm'd afaneh92 to try to clear this up.
If my excitement has led us astray, I deeply apologize.
