[Q] HELP !!! Unlocked Galaxy S GT-I9000M - Data Connection Not working

Hi
If anyone can help me out i'm having a little bit of an issue. I just unlocked my Galaxy S phone with one of your guides on this website, but now i face the issue of not be able to connect to my Data. I'm with Rogers just unlocked the phone from Bell, and having a real hard time figuring out how to get it to work.
Now i can make calls and SMS and such but i cannot use my Data Plan ?
Anyone
Thank you in advance.

You need to enter the APN information for Rogers. I don't know it, sorry, however it should be easy to come by.

How would i go about changing the APN ?
Sorry real newb to all this

Hey Ben
I figured it out, thanks a bunch
Take Care

Same Problem - How did you solve it?
I have a Samsung Galaxy S Vibrant (From T-Mobile) which is receiveing calls and texts on Rogers (CAnada) wireless network, but my data connection is not working.
Can you tell me how you got yours to work.
Cheers
Sam

Make sure your on CDMA and not global mode. Settings :network then make sure CDMA is checked and not global

They did not set up your phone in store your you? They are kind of Nazi about that.
Do you have your SIM card installed correctly? If the SIM is not in, or not in correctly then 4G wont work.
Also do you have mobile data turned on, have to ask.
Mine data is set to global and works but yeah try setting it to CDMA/LTE

Settings, Tethering & Networks, Mobile Networks, System Select, LTE/CDMA. If you don't have that option, something is up with your phone, might be a bad sim or something, take it back to the store.

I've had mine on global since forever. Global does not turn off LTE. Perhaps something is physically wrong. Check the SIM

You need a new SIM. Happened to me. Did a bunch of research and there was hints of the SIM that comes with the phone by default sometimes having an issue with 4G. I called Verizon and they sent me one next day. Installed it and been fine ever since.
Try it, It is free and I am pretty sure it will fix it.

If you have a local (not 3rd party) store, you can get a SIM free there also.

Didn't have any issues with mine out of the box or now that I've finally got all the T-Mobile stuff working with it's CSC and apps. I've called out and received calls in both circumstances and had zero issues. What provider are you with here?

How did you get the tmobile csc? I was having call issues too but when i changed the ims settings and enabled volte calls got better but when im in a area with bad lte service calls are taking long to go thru. Could that be a csc issue? Also i dont see a link that the op is saying you provided that fixed the problem

Extracted it from the T-mobile ROM and dropped the files into a CSC changer flashable zip for an S8, modified it so it would work on my Note 8 and flashed it.

i spent 45 mns on t mobile call then i realized why i'm calling them since my phone isn't a t mobile one lol
i flashed Kalm file
and that fixed my issue
hopefully the main dev can port it over
i don't think he's gonna be too happy with his file being modified like that

Not Odin, it is a flashable zip so you'll need a custom recovery and probably root

Ok cool glad i asked before i did anything lol

Ended up calling t mobile and they had me reset my network settings then turn off my phone while they did something on their end. Turned my phone back on and boom no more problems. Didn't want to try root yet until there was a more stable one available. Thanks for all the help

yeah it's in my thread here https://forum.xda-developers.com/showpost.php?p=73858645&postcount=17
But I redid it last night after someone confirmed that they didn't even need the Note 8 CSC files, and I deleted out everything for other carriers so the new file is only about 120mb instead of 300-something.
I can post that up after work if you want to wait, uploading is blocked here at work for some reason.
Have to add that wifi calling still doesn't seem to be working, but VoLTE does since calling does not drop me from LTE. I have no menu settings for either still, but after doing a full reset, reflashing etc I have the wifi calling quick toggle but it doesn't seem to turn on all the way - the "on" color is light-grey instead of white like everything else (dark grey when off) and in the System UI tuner app, no icon is set for Wifi Calling or VoLTE.

Yeah it's in my Exynos T-mobile CSC thread but I've got a better smaller one now. I took a pack that @TEKHD made for the S8+ F variant and switched out the files with Note 8 T-mobile files but there is a little bit left to go to make WiFi Calling work on our N950N, VoLTE works, HD voice works, video calling works, but I'm still trying to figure out what's missing for WiFi calling. It's menu isn't even showing up yet.
Current flashable zip is only 88mb and I'm fairly sure whenever I figure out the remaining files that need to be copied over it won't be much larger.

I'm about to do a factory Odin flash to stock and test the latest version - if it works properly I'll post it up with a link - though I don't want to step on anyone's toes since the core script and idea belongs to TEKHD.
Fair warning as far as right now I still haven't figured out why WiFi Calling is missing, I set up this the same way he has his S8+ pack for their F variant aside from adding a few framework files that I found referenced in the Tmo Wifi Calling apk that don't exist on a factory Korean N950N but are on the Tmo ROM, and my theory if this next attempt doesn't enable WiFi Calling is that the N950N is fundamentally either just missing more files that need to be in place for it to work and I haven't found them yet, or that it has different/incompatible versions of some files that the T-Mobile Wifi Calling needs to function.
In other words I have 2 more things to test, then I am going to try fully wiping, flashing an N950F-based ROM and apply the T-Mobile WFC pack to that, since the S8/S8+ options that enable it for those folks are for the F variants, not the N variant but the F and N have the same hardware.

Sounds good. I went through the same things with my Note 2 years ago. I figured it out and got WiFi Calling working.
Fwiw, I have no interest in Wifi Calling on my Note 8, as my signal (also T-Mobile) is always good, and I use Hangouts (or whatever) when I'm on Wifi, for free calling.
I don't have Note 8 yet, but will order soon from the same seller as you.
Do you have any other suggestions for getting everything up and running for T-Mobile (except WiFi Calling), or is simply flashing the CSC file?

If you don't care about Wifi Calling yeah I would say just root, custom kernel, and flash the CSC. You'll get VoLTE, HD voice, video calling etc

Can I install stock AT&T ROM on an unlocked S10 from Samsung

I just got my new unlocked S10 all set up dialed in. Model SMG973U1ZBAX.
I put in my AT&T SIM card in and went to turn on Wifi calling and couldn't find it. I've since learned that if you have an unlocked phone, you can USE the AT&T network, but you can't get Wifi calling (which is a must for me), Visual Voicemail or HD Voice.
Instead of flat out returning it, can I just flash the AT&T ROM and it would be as if it was a a stock AT&T phone?
I know I would get all the bloatware and stuff like that, But I have to have wifi calling.
Are there links yet to Stock AT&T ROM for the S10? I couldn't find any on the site.
Thanks

Yes you can there's a thread somewhere in here with specifics on how to do it. I know you have to flash thru patched Odin and make sure you also flash userdata and csc to corresponding carrier.

Root is unrelated to firmware flashing. You only need Odin and the fw package. Your computer may, or may not need the Samsung USB drivers to be recognized.
Samfirm can be used to pull updates. You might find it on sammobile or updato, haven't checked.

Sigh. Well. I can report and confirm that you can not use Wifi calling on the AT&T network with an unlocked S10.
Even though I loaded stock AT&T firmware, and was up to date, it just won't work. Gotta return the phone.
I've been dealing with their advanced tech team for over a week and they said that because the IMEI number shows it's an unlocked phone, the system keeps denying Wifi calling.
We actually got it to work at one point. It was a 3 day process with one of their techs forcing my IMEI number through their system. It worked for about an hour, then their system caught it and kicked out it's provisioning.

Galaxy S10 unlocked ATT firmware question
Hi I recently got Galaxy S10 Unlocked phone on online. At first i didnt get ATT wifi calling options appeared in my phone. Later i followed same thread that has 973U ATT firmware links, and flashed using ODIN. I can see all ATT apps and ATT wifi calling option now but i cannot enable it. When i enable it i got a message saying we cannot turn on WIFI calling on this a device and error code EDS0008. I tried to call ATT folks, but they are saying WIFI calling and HD voice is not supported on this unlocked device. Somehow they are seeing 973U1 as model number, but i had 973U as model number. I tried chaining sim to old iphone and I saw WIFI calling is working with IPHONE, but its just this phone I am seeing error. I am not sure what to do now. Did you see this issue ?
Can you give me exactly about the files you used and post steps to get att wifi calling ?
sorry for posting questions in multiple threads

I have an unlocked S10e and I use T-Mobile and before even flashing T-Mo firmware, I did have WiFi calling out of the box. Change carrier

Your best bet is to do an exchange for an AT&T version.
You can Flash the AT&T firmware. But there will be no way in h*** for you to actually enable the Wi-Fi calling feature since they block those IMEI numbers on their servers. YOU HAVE BEEN WARNED. YOU MIGHT NOT BE ABLE TO REVERT IT BACK TO THE OTHER FIRMWARE.

I can confirm Wifi calling works, HD voice and a WAY WAY WAY better signal. Prior to flashing to ATT I could barely use my phone on my subway ride home... Now it works very well the entire trip.

I'm going to attempt to flash with the clean boot version and see if that changes anything. Did you do anything different or additional to get it up and running. Not sure if it matters but I'm in Southern CA.

I'm away from the computer I did it on but I used the SAT1 firmware file and then manually updated all the way back up to the June update.
The updating part is/was a major PITA as it wiped the device each time. I'm hoping i'll get OTA's when they are released. Time will tell.
I'm in the Bay Area on ATT and it activated right away on the base february firmware I installed initially. Also I don't think I did any userdata stuff as I don't remember choosing it... I'll update this post tonight when I can check all the files I d/loaded on my machine at home.
Couple other things:
I can't find it right now but I followed a post that stated to make sure the SIM and SD card were removed during the flashing process. Not sure if that makes a difference.

did you ever run the unlocked firmware on ATT or did you flash to att before ever using an active sim? i had heard some speculation that once you run an unlocked phone, then it gets registered as "non att"... keep in mind this is 3rd hand info and hearsay.
edit. i guess i failed to read you short post... i see "prior to flashing" spelled out for me right there....

Any chance you found those other posts you mentioned above? I continue to be unable to get wifi calling on my phone.
By the way for anyone else, while I did not get wifi calling, visual voicemail, etc. I do see an improvement on my cell reception over the ATT network.

T-Mobile to AT&T

Hi All, I'm trying to make my T-Mobile Note 9 work on AT&T. Using odin I put on the latest ATT version on my phone that I could find -- N960USQU1ARG6. It boots and works fine, but it shows Android 8.1, I don't get wifi calling or there's no place to turn on VOLTE, and when I say update software it says "software up to date." So, I'm assuming that ATT still doesn't think this is their phone.
Any ideas on how to fix this?
Thanks!

Any ideas on how to fix this?
Thanks!

Att has Pie firmware for the Note 9. Just do a search for the newest Pue update and flash it using Odin.

Thanks for the response. That will fix the Wifi calling and VoLTE too?

That I do not know for sure. It doesn't hurt to try though.

Well, it might. I'd really like to understand what's wrong with it before I flash more.

Well the first thing you could do is do a factory reset, or verify with At&t if it's a feature on your account. Not sure how theirs is setup compared to T-Mobile's Wi-Fi calling. It won't hurt to flash unless you've got stuff you need to backup and have no way to do so.
I don't think anything is wrong with your device. All of the N960U devices are the exact same. The only difference is the software. You don't even need to flash a different firmware for it to put the carrier bloat on the device based on the sim card inserted. It's already included in the Software package on the device, just dormant.

I can't see AT&T Mobility (or any carrier, really) willingly remaining in the trailing position vs. the UnCarrier (who has offered Wi-Fi Calling as a feature (even to their MVNO customers) for over a year - yes, I have had it that long personally) - the only time I don't use it is due to support of the *router* being iffy (some residential routers have issues with Voice over Wi-Fi; the same applies to some business routers).

I went to ATT as well and it took some time for me to see the update to 9. Not sure, when I was with T-Mobile it always showed updates right away. For ATT, I was able to find the ARJA firmware with a CSA7 update that expedited the process. It also took around a day for wifi calling to show up. ATT is just slow to enable things perhaps?
