Hi all, new here and phone ignorant.
My parents wanted new phones this past Christmas and they like Samsungs. They had Galaxy S3's and so I bought them 2 new Galaxy S9's, model SM-G960U1. They worked great out of the box. I moved over their ATT Straight Talk sims and they have had no issues. They live out in the country and these phones get great reception.
Fast forward to last week I decided to order the same for myself. The phone that arrived was a Galaxy S9 model SM-G960U. I stuck in my ATT Straight Talk SIM and at first thought everything was OK. But, then realized the phone is missing Volte, wifi calling, and gets horrible data coverage and very weak voice service in the country.
Is there anything I can do to fix this, like flash the firmware? Am I stuck with it? Should I try returning it?
Thanks!
Flash it to U1 (unlocked) as your phone currently has "U" firmware (originally carrier locked). Read this thread to see how: https://forum.xda-developers.com/galaxy-s9/how-to/how-to-flash-u1-firmware-to-device-t3765200 . My S9 is an AT&T variant and I flashed it to The unlocked US variant and I use it on Simple Mobile. Wifi calling works, cellular data and cell signal - everything works perfectly.

I have a verizon Galaxy S3 which I rooted and set up as a world gsm phone through the simplified tutorial here

I'm currently in Hong Kong using a prepaid 3 simcard, I can call and text perfectly fine but I don't have any 3g/lte internet. I can only access the internet through wifi but my simcard has data capabilities.
The APN that shows up is under "ipc.three.com.hk", i've tried the other ones but only the former shows up in the APN list.
Is there something I can do to fix it?
Well first of all, this is a SPRINT Galaxy S3 Forum. Why not ask this in the VERIZON Galaxy S3 forum, http://forum.xda-developers.com/forumdisplay.php?f=1708 . Might get better answers there.
so i just got my SM-900W8 for Wind mobile today, had to buy it with two months service, but then was able to send half of the money i put down on that service over to my old account, switch the sims, and now i have my same old number and plan on my new note, and i'm only out an extra 20 bucks (still bull****, i know, but i wanted it today and wasn't going to deal with waiting, for any reason.... maybe too impatient lol)
anyways, after i bought it, i stopped by the bell store and asked what model they sell... they showed me the box and it was the exact same model number... SM-900W8. i then went to rogers, same thing, and telus i presume will be the same since bell and telus share towers etc
so, my question is, if i unlocked my phone, could i simply go get a bell rogers or telus sim card, and throw it in, and have it work? the region issue is a non-starter for two reasons - first i didn't even have that region lock sticker on my box, but second, the robelus sims would all be the same region, so it shouldn't matter in the least. what i'm wondering is, would the bands be the same, or at least some of the same to the point of working? i know that wind uses AWS bands and robelus does not, but since they are the same model number, is it possible that they have radios that are compatible with all four carriers in this phone?
if not, can someone explain to me how to find out what networks this phone would work on? i mean, it sounds like people are unlocking their tmobile phone and using it on att, and from what i remembered, att is not aws, and i thought that rogers and att phones worked together... ARGG what gives here?
also, are the tmo phones the same model number as mine? or did they use different phones than wind this time around?
finally, if i'm looking to root this or put a rom on this, am i looking for the tmo roms and other stuff like i was with my sgs3 or am i looking for something else with this new phone? where can i find this info... i haven't been able to find much about this yet, i guess not many people have this phone on wind yet

Thanks for the answer, but I don't know for sure what bands the big three use, can anyone tell me if this phone will work on those big networks?
Also, any answers to my other questions ?
Rogers, Bell and Wind all use the SM-900W8 variant probably with just a different modem / QCP file.
So does this mean that there is some chance of, in the future when things get cracked, of flashing a new modem etc onto it our something

to answer my own question, yes, i unlocked my n900w8 from wind with an unlock code, and i was able to see whatever networks were attached to the sim i put in it. rogers, bell, telus, koodo, virgin, fido, wind, probabaly chatr if you really wanted to use this device on that dumb ass carrier
so yes, you dont even need to flash other modems... it just works
i did try flashing bell/rogers/puerto rico roms on my device and all had the same result, it all worked, and it all worked fine
Samsung galaxy note 3 SM-N900W8 from videotron (canada)
Hi, i have a Samsung galaxy note 3 SM-N900W8 from videotron (canada) and i unlock with a code to use it with fido and the phone show only the 3G internet, is there a way to enable the LTE? when i go to setting mobile network, network mode show me only 3 options WCDMA/GSM (auto connect) or WCDMA only or GSM only. I tried to root the device to do like this forum said ( http://forum.xda-developers.com/showthread.php?t=2489766 ) and when i root it it says pass but it stuck on rebooting and something red is written on the next line and samsung logo is there too. anyone can help me to enable the LTE network?
Just wondering if it works on all carriers or should I wait for the unlocked version ? Thanks.

I have a vzw line. Popped in vzw sim. Then popped in my tmo sim. Data and calls work. Speed was faster on tmo sim though.

mine works well but i cant get video or any of the tmobile **** like that to work
I just picked up a Verizon S8+ (i had a T-Mobile one but just returned it) and i popped a T-Mobile SIM Card in it and i got a message saying "This is not a Verizon Wireless SIM Card" and it wouldn't let me use it. I thought it was supposed to be unlocked??
It is unlocked. After swapping Sims the only change you got to make is change preffered network mode from LTE/CDMA to LTE/GSM oh and go to APN and choose your new sim card apn. And thats it. Ive tried all carriers on my Verizon S8+ with no problems

What probably will not work on any carrier phone other than TMobile will be WiFi calling when using TM SIM.
Hey! I need to know if I buy a s8+ in Verizon, I will can use in Chile with my local carrier? I can read that you don't have problems changing the carrier in USA, will be the same if I use the phone with a Chilean Sim? Thanks!
I have a Verizon S8+ on AT&T unlimited service and it works perfectly. So you'll be good for Tmo as well. I have no clue about Sprint tho.
I have a Verizon S8+ on att and it works great. Does anyone know if I get HD Voice with this combination ?
Verizon unlocked S8 plus on T-Mobile working flawlessly for me
Verizon unlocked and works very well in France on the Orange network.
When I got my VZW S8+ I popped in my tmo sim first thing. It worked flawlessly out of the box. I didnt even have to add any APN settings as all of the tmo settings were built in. Awesome job sammy!
What about video call ect I'm having issues getting that **** to work is u pres *#77467# it says false on all the **** why won't the ims register that controls all that
I have an issue with s8+ using AT&T sim. The issue is that the phone shows a plus sign in front of my all incoming calls treating them as international calls. Does anyone know the solution?
The phones are completely unlocked, what you need to do is look up the VPN settings that T-mobile, or at&t use for their phones and set them accordingly. Though some functions might not work with non-Verizon carriers through changing these functions. (messages, video calling, etc..)
Thank you all. I bought the s8+ from Verizon out right because I wasnt sure if I was going to stick with them. And it looks like I am moving to t-Mobile this month, I was going to look into flashing the firmware, but I was worried since I used Samsung pay like crazy. So I am fine with just disabling the verizon apps and going from there.
Anyone know if the phone will still get updates if I swap in a T-Mobile SIM, or a Verizon-compatible one from Straight Talk while still on the VZW firmware?

It will if you use the VZW software update assistant. I've done 2 updates this way on my Verizon S8+ with my tmo sim in there. Works fine.

Sounds good. Do you know of the Verizon phone has all the bands of the T-Mobile version?
Fully work - no. Things like HD calling and wifi calling wont work without t-mobile software.
I purchased a Verizon Galaxy Note 10+ 5g from ebay last year to use for Total Wireless. Well the phone wasnt compatible with Total Wireless at the time and I had to switch to Verizon prepaid. Now the phone is compatible but I cant add APN's to the device because Verizon has greyed out the option. I bought a US Mobile Sim card so I can switch all of our phones over since it is cheaper and is a Verizon MVNO, but I cant get everything to work on my note 10+ 5g. I was able to download an app that let me add APN's and the LTE comes up but now I cant get VoLTE to work. Its turned on but when I make a phone call, it switches to 1x. This is a problem since Verizon is doing away with their CDMA Network. I have spoken to Verizon, US Mobile, and Samsung with no help. My other Note 8 will work just fine when I put the US Mobile Sim card in and my Samsung a71 5g wont work at all and wont let me add APN's even with the app.
I have been doing research and found out about SamKEY and bought some credits to change the CSC from VZW to XAA. I was in the process and it gave a warning about locking the SEC so I decided to do more research before I screwed something up.
The phone is unlocked but for some reason, Verizon phones have these issues with a Verizon MVNO. I can add the TMO sim card from US Mobile and it will allow me to edit the APN's without an issue but I get zero coverage here so I cant use it. So how can I change the CSC to get VoLTE working on a Verizon MVNO? Or can I even change the CSC on this phone? I am so sick of Verizon phones but Im afraid to buy an unlocked phone since It doesnt support all of Verizon's bands.

IDK about unlocking an US device. I prefer unlocked devices.
US unlocked versions of Samsung devices are called "U1". It's part of the model number/name.
E.g. SM-G981U is the US locked Samsung Galaxy S20 5g (like for Verizon), and the SM-G981U1 is the US unlocked version of the same device.

Thanks for the reply. I ended up selling the phone and buying a Google Pixel 4 XL. Saved some money and its unlocked. Ill never buy another Verizon Edition of the phone again.
I have searched for hours without any luck. I have been with an AT&T MVNO (Unreal mobile) for two years. During the 3g shutdown I was unable to use VOLTE on my S8 (VERIZON FIRMWARE). I found out the only way to use my S8 on UNREAL was to have AT&T firmware. I spent countless hours trying to flash ATT firware onto the Verizon S8, but I was unable to do it by flashing, but I found another way. I put a TMOBILE SIM in my S8 and it automatically loaded the TMOBILE firmware. Once the S8 was booted up I was able to run a USSD code (*#272*IMEI#) through the dialer which allowed me to switch to ATT firmware! Problem solved!!!! But a few months later my S8 was lost and I got a S9 (Verizon Firmware). I tried the same method as I used on the S8, but it doesn't work. When I put a T-mobile sim in the S9 it does not automatically change the firmware like the S8 did. From the Verizon dialer on both the S8 and the S9 it will NOT ALLOW USSD codes. Does anyone know if there is a way to run the USSD code (*#272*IMEI#) on the Verizon S9? Does anyone know why the Verizon S9 doesn't automatically change to T-Mobile after inserting a T-Mobile sim? Are there any other sims I can insert in the S9 to change the Verizon firmware in order to run USSD codes? Flashing my S9 is not an option for me because I must be too stupid. Anyhow thanks for your help!!!!
Seem's you+I have similar problem! I have s9 verizon unlocked,but I am with consumer cellular. They went to 4g recently now no call or recieve call! They gave me new sim, still not working! Told me shorter mobile wavelength from tower's! Last update on this phone was 2018? Won't update normal procedure! Wondering since this is U.S.A version if any way to update to 4 g? I'm fine on micro-soldering but when it come's to tech,a little to old I guess!!Lol Any help appreciated!

In my case I had a Verizon unlocked s9 and it turns out Verizon has bloatware that prevents many MVNO's from using VolTE. After tons of research the only solution I found was using patched ODIN to flash unbranded stock firmware in order to chance my model from a U model to a a U1 model. Now the phone works perfectly. Someone should file a lawsuit against Verizon (and ATT) for circumventing federal law on unlocked phones (technically they are unlocked but you can't use them because of their bloatware). It really is a major scam.
