Galaxy S8 Active 3g/4g in Europe? - AT&T Samsung Galaxy S8 Questions & Answers

Hi
I bought unlocked AT&T SM-G892A in US and brought it to Europe.
It says that it covers all GSM bands and should be compatibile, but on my European sim card it only works on 2G(EGDE) ("E" on top).
I've been playing with settings enabling all options in mobile network settings but to no avail.
You know what could be the reason? My software is g892aucu4bsc1 . Could the phone be damaged?

Only where I can buy it is in China Telecom, right?
It is locked on country region or smth?
I'm from Europe, will I be able to use it in my country?
Does it need to be activated in China and talk 5 minutes or smth..?
How about price? I saw it's about 660 euro, it is true?
Help will be appreciated

You will make your phone international without chinese...i don't have the 4.3 who marrkdaviid says but the former 4.2.2 wihout any problem.
So,it depends from whom and where you gonna buy it..as i said,mine brought me a friend from a shopping malll in Shangai
I thing antutu can check if it is original...so,from where are you plan to buy it?
P.s send an email to send you the info

I don't understand what you mean?..
I decided N9002..... Cause I've had S4 for a half a year already, so beter change.. So I'll fight with size somehow
But when I buy N9002 from china and see all those chinese apps, what to do, how to remove them? Can I just flash and let it be like stock without chinesse apps?

In samsung'sweb site says that first sim slot supports 3G cdma and 3G UMTS..WHat does it mean? Umts is supported network in europe?
network info
Found G9009D's chinese manual at http://downloadcenter.samsung.com/c...inaTelecom_China_Kitkat_Chi_Rev1.0_140514.pdf
I dont know chinese but on page# 13 it shows that SIM1 needs micro-UIM and SIM2 needs micro-SIM.
I thought I could use but slots with GSM-SIM but I was wrong. Now I know that if I want to use Slot1 then I need to get UIM card (if my carrier has CDMA network and can give me UIM card) or else I cannot use Slot1 (only Slot2 with any GSM SIM).
Although my seller claims that both slots are unlocked I cannot test Slot1 until I can get a UIM card (to confirm if it is not network-locked on China telecom).
@rankoradza
Why did you go back and delete all of your posts in this thread? That just devalues the thread for anyone who has similar questions and bothers to make a search.

International S7 edge please help

I previously owned an att variant S7 edge. It was used on Straight Talk towers. It broke and I was forced to buy a new one because of no insurance. I went on and bought the International version on Amazon SM G935f.
I notice that there is no "Mobile Networks" option on the phone whatsoever. Without that option, I can't set my apn settings. The Sim card doesn't seem to work either. Is there something I'm doing wrong? Has anyone else experienced this. Please help!
In the essence of the simplest solution is usually the right one... are you sure Flight Mode is not enabled as this occurs when it is?!
Sent from my SM-G935F using Tapatalk
I live in US and bought an international version also. It would not show mobile network until I inserted the sim card. Iam also on straight talk using att towers. so do u insert sim and recheck your setting and see if it appears?

Flash Verizon S8 with european firmware

Hi guys,
I bought a Verizon s8 in the states and wanted to use it in Europe. I live in the Netherlands, so I swapped in my Vodafone some instead of using the Verizon Sim and everything works fine besides mobile data. I can not change the APN settings as they are locked. Carrier says it's Verizon though it's using the Vodafone Network.
So I was wondering, can I flash the firmware with a european version to get access to the APN settings and remove the carrier lock?
Best
the s8 verizon is not locked just put your sim card in and thats it.you cannot flash international rom on the us version odin wont let you it will fail even if you somehow made it it will brick the phone.the reason is because the us s8 version uses snapdragon chipset and the s8 international version uses exynos chipset they are completely different.
the option you have is to flash the us unlocked version to the verizon s8 i did on mine i have verizon also.

I was wondering is there a way to add more international languages on my s8+. I have managed to change parts of it but on menu and while scrolling in facebook it doesn't recognise i.e some norwegian / turkish letters and doesn't switch language in parts of menu.
The model i have is G955U1 ?
Thanks again.

Tv87, I am in the exact situation as you. Have you resolved your problem? If so, what was the solution?
I just moved to the Netherlands a few weeks ago and switched my S8's SIM Card from Verizon to Vodafone. Everything worked fine except for mobile data. The Vodafone rep told me that my APN settings were grayed out / locked; therefore, until they could be edited, my phone would not receive mobile data.

They are not locked, the phone still thinks it has a verizon sim and that's why you cant edit the settings, do a complete factory reset.
And anyways, even with editable apn settings you wont get lte, because your s8 is lacking the european lte bands.

What makes you say that?
https://www.phonearena.com/news/Che...on-T-Mobile-and-Sprint-use-in-the-USA_id77933
Says:
"In Europe, most carriers base their networks on bands 3 (1800 MHz), 7 (2600 MHz) and 20 (800 MHz). China, on the other hand, uses a whole different 4G LTE standard - while the Western world has rolled out FDD-LTE networks, China and large parts of Asia use TDD-LTE."
And several places online show all those as being supported on the g950u.

I said that because most phones that verizon sells dont have the lte bands for europe, but according to frequency check, it is compatible !
Sorry about the error

I did a factory reset while my Vodafone SIM Card was in the phone. I am now getting the following message:
Sorry, we're having trouble activating your phone.
If you're moving your phone number from your old phone to this one, make sure your old phone is turned off.
In addition, I get the following message on the very next screen:
You can set up your phone using Wi-Fi, but you won't be able to make or receive calls until your phone has been activated on the Verizon network.
Is there anyway to unhinge my phone from the Verizon network!? Before I left the United States, Verizon assured me my phone was not locked to their network; however, it appears to be based on the messages received after factory resetting my phone.

What you can try is to flash the USA csc instead of the VZW one that you have right now.

if you have dual sim version you should check if the sim is in the correct slot (only first slot has lte)
else you propably dont have lte enabled either in the settings (search for lte in the phone settings) or your provider did not enable lte for you

I'm pretty sure that it is a GSM only phone. The W-CDMA listed in the specs is actually UMTS, the competitor to CDMA2000 and the 4G standard used by GSM networks.
What network are you trying to connect to?

Yes it is CDMA2000 EVDO.
When I insert *#*#4636#*#*
I have cdma among networks' list.
I don't think it is going to work. Which cell provider are you trying to use? In what country?
Most US reviews of unlocked phones specify that they will only work on GSM networks like T-Mobile.

I'm from Yemen Arabia. My network is Yemen Mobile Telecom.CDMA2000 3G EVDO.
and the rn7 reads the sim information like network name and services on the sim .
I have no idea about Yemeni carriers, sorry. Have you tried calling them?

Hi I don't know if this helps anyone and I know this is an older post but I think I found how to turn CDMA on. developer options enabled, go into about phone settings and tap "internal storage" until it opens up phone info. Choose the sim slot and there you can set preferred network to CDMA only or something like that. I don't know much about mobile network but I saw that CDMA setting in there.
That menu you get after clicking on internal storage is the same as typing *#*#4636#*#* in Phone. I've tried changing it to CDMA only or LTE/CDMA but nothing happens, the UIM card is recognized but it can't log on to the network.
More info: the Global Rom version of the phone only works with CDMA carriers that have LTE data and VoLTE voice. It does *not* work over CDMA 1x or EVDO. I had to swap a new China Telecom UIM to get VoLTE working.
Hi. I bought Redmi Note 7 Pro from aliexpress with global Rom. It does not connect to my carrier in Poland. The status of the sim keeps changing from no service to emergency calls only every 2 seconds. Is there any way to fix it?
RN7 not work on the network CDMA.
