Backstory: My sister bought Samsung Galaxy S8. She lives in Canada and after using it for a while, she sent it to me. I live in India and i factory resetted the phone, put my jio sim in and to my surprise it didn't work.
So my problem is, how do I make my sim work with this phone.
Model name: SM-950W
Android version: 9.0
CSC: KDO
No root
Things I have tried:
- restarting with sim in it
- turning on and off VoLTE option
- changing bands with some makeshift methods
- installing jioPhone application (this worked, but it is very messy as I need to have my mobile data turned on, and I can't use my Wi-Fi with it. So that's a major issue)
Please someone find a solution because I really can't make do without it ;-;

You need to swap the SIM card/the phone with another phone/SIM card to eliminate the causes from the SIM card/the subscription/the network...
After eliminating all causes from another sources, you can start to fix your phone.
Thanks for your advice i change my sim but nothing so i do a factory reset and everything now is ok ....:laugh::laugh:
:good: FINALLY SOLVED :good:

My friend has the same problem. He was using Iphone 5s and I convinced him to switch to Samsung/android and he did . But so far its been problems for him on his S5 duel sim SM-G900FD.
I tried to fix it for him but no luck so far. Things I tried,
- Factory reset
- swap sim
- use only one sim
- software update from (XXU1ANF7) to (XXU1ANH2)
Last thing i am doing for him before I give up is to turn off the smart switch between data and wife. Other than that i'm not sure what to do. He always fix the issue by going to airplane mod then turn it off, but it will come again eventually.
Any help is appreciate it as i am trying to get a new guy into android world

1- Does this SIM works fine on another smartphone without any data connection problem?
2- Check the APN settings. Consult your service provider for the proper parameters.
3- Check for the baseband version? Try to flash another baseband...

I was able to fix it for him. It turns out it was the smart switch thing on his phone was enabled. I found it under wireless icon
Hello, first to say, im not a newb, noob, newly registered, or a guy who dont understand anything from android.
Im not posting stupid topics, or topics which answers can be found easily on internet/google/xda/forums and such.
I am running stock rom, only rooted (i used to root it only to apply some xposed settings and clear some unnessesary apps, nothing more, nothing less).
Here is the description:
My phone has no warranty, i bought it online, brand new from UK, simfree. At that point, i had no problems with the connection. i received OTA Update - about 50-60 mb, but the phone remain 4.2.2 as it was. I still had no problems with the connection. After some time, the phone was left alone inhome for a few days, may be a week, it was turned off and it was not used at all. When i got back, i inserted my sim card, and i saw it is showing only G icon, and no 3g/h/h+, nor even 2g. I live in big city with very good network coverage, so its not network problem. I dialed up the customer service (Globul Telenor Bulgaria) , explained them my problem and asked them to check if its operator's problem or sim card problem, but it is not. The sim is fine, so is the network coverage. I dont have other operator's sim card to check the phone. I tryed several possible solutions found in google/xda - turned off the phone, removed sim and battery and left that way for few hours, still have the problem, tryed to switch operators manually and register sim card to other operator then back to mine, not working. Several times reseting/ deleting APNs, switching airplane mode, data off/on, adding apns/searching for networks and all available combos, not working asked Globul Customer support to send me new settings- not working. The only obvious thing i havent tryed is the factory reset (I still need to do a backup first and dont have time to do it right now.)
In Settings- More networks - Mobile networks- Network mode i have 2 options - 2g/3g auto connect and 3g Only. When I choose only 3g - i lose any signal, like there is no sim card. Reverting back to auto 2g/3g is registering my sim back to Globul network.
Then i decided to root my phone if i can find a fix for the connection. Rooted with CF-Auto-Root thru Odin. (The 30sec Root)
Looked for some tweaks in xposed modules and settings, i couldnt find anything related to 3g. Still looking for a solution...
I repeat - my phone was completely stock and non-rooted when the problem occurs! Now is rooted with stock rom. (this is the diffirent from every topic i searched.)
Im attaching some screenshots, if someone can help me. 2g is really annoying and slow as hell.
Well the first thing I would do is update your phone. You are running 4.2.2 which is old. Update to the latest version, that could either be a stock rom or a custom rom.
After that do a factory reset. Make sure you backup your internal storage etc, because it will wipe it clean.
Factory reset, updated to 4,3, after that 4.4.2 problem still persists.
No 3g at all. Its not the sim. Any way to fix it ?
Soo no way to fix it? Should i give it for repair?

Hi XDA
So i came across a very serious issue 2 days ago basically rendering my phone almost useless as calling is very important to me.
I have been running purify CM13 rom on my samsung note 3 N9005 Snapdragon flawlessly for 2 months and out of the blue yesterday my phone displays Emergency calls only- then my service provider name, i tried the sim in another phone and it worked i also tried other SIM cards form other service providers in my phone and they all show the same thing but the phone can actually identify the network provider also when i remove the sim it says no sim inserted.
Hours upon hours of googling and troubleshooting and still no luck in fixing this issue whatsoever. I tried a lot of stuff like resting the APNs, manually setting the network, Switching form 3g to 2g and even wiping my device and flashing the newest version of the rom again but the problem still presists.
At this point i have no idea what to do, any help is appreciated.

Ever found a solution?
Phone: Galaxy S8 / SM-G950W
Network: Telus
Problem: This is the strangest thing I've ever seen! My phone is showing incoming calls from my wife's number and another relative as "Private Number". All other calls are identified correctly. Their network is 7-Eleven Speakout.
The strangest thing is, if i take my SIM and use it on a different phone, their numbers show up just fine. Also, if i put another SIM from a different provider in my S8, it also works fine. I even changed the SIM from Telus and got a new one but it didn't help. I've reset the network settings on the phone, reset the data on the phone app, nothing worked.
It seems that the problem only happens when I use my Telus SIM on that specific S8 phone!
Unfortunately, wiping the phone is the least favorable solution as it's not rooted and I have tons of apps that it'll take considerable effort to re-configure them. I don't backup to samsung or google for privacy reasons. Used to use TitaniumBackup, but since no root exists for this phone yet i cannot use TB in this case.
My question is: Does anyone knows the process of call identification on android phones and may have a good guess why such a behavior may happen? I have a bit of a technical background so i may be able to understand any technical explanation...
I need help on this, as now i have to answer any private number that calls me when i'm away as it could be a family emergency, unfortunately telemarketers and spammers are not making my life any easier and i would love to be able to block all unknown calls again like i used to...
Thank you all for your help in advance, this is one of the strangest issues i've seen and i only ask for help here after i depleted all other ways...
Cheers!

A friend is having the same problem, albeit worse - it's all incoming calls show as unknown.
Swapped my SIM in and it's fine. Swap back and it's stuffed again. The suspect SIM works fine in my phone tho.
Even got a new SIM and ported the number to it, but same problem.
Out of ideas to try.
Looks like it's time to replace the phone

Hi guys,
Been into android modification since 7 years but gave up since my last 2 phones. So i got this unlocked at&t galaxy s7 in uae and it worked like charm, the network and coverage. I then started usingthe phone in pakistan too and it worked well even here. So one day i connected to gear vr so that i can initiate the oculus data installation as first time setup but the gear vr kept on disconnecting automatically. I have used it before too but never had problem. Then i rebooted the phone and i find that i have no signals at all even though my sim contacts are being displayed and there is no “no sim” message on statusbar even. But dont have any signals at all. I then inserted my sim to iphone and it was working perfect. Then i inserted different carriers sims to s7 but yet they werent working even. I then cleared the cache, factory reset, cleaned the sim slot and the sim , but no success. I left ky ohone turned off for days andeven drained battery 100% many times to calibrate and perform hardware reset but no success. I then sent the phone back to uae for repairing from my friend as i thought that the antennae were the one’s responsible but before he even thought of disassembling the ohone, he inserted uae sim and it worked perfectly. Call and data were working perfectly. Any idea what is the problem? Kindly let me know pleaseeee. Is there any problem with frequency? Like gsm or cdma? But the phone worked before. I tried to enter the settings of manually selecting networks but there was error popup “No service and signal”. Signal strength 0asu -113dvm

Forgot to tell, my phone has never been rooted, i even tried to enable/disable “Enable hd LTE features” but no luck. Its on 7.0. Dont recieve OTA. Not blacklisted either. Pakistan doesnt have CDMA. I have even noticed it recieving weak signals compared to my iphone when the phone was working ok. And my radio is showing to be off and when i turn it on from the dial code menu. It doesnt keep turned on and it turns off automatically. I still have the imei amd baseband version. Dunno what the issue is.
Kindly reply guys
Please help

Manually enter your carriers information you'll have to ask them or look it up online sure its easy to find they might even help you in store
Its not good for you to buy these US phones outside of the US because changing CSC to INS/INU/PAK could prove to be difficult being it was never supported by snapdragon G930A model but only exynos G930F although it's not impossible
/system/csc/others.xml is where your answers are waiting for you unless you update to oreo then it'll be in /system/omc/cscfeature.xml and cscfeature_network.xml
You will need a root file manger to be able to see what I'm talking about then you will have to figure out what those "strings" mean
Unless you want to mod and figure out make your phone awesome just flash other US firmware that uses gsm network only i think ATT only uses gsm and you can root to debloat ect.
Here's a method for rooting
https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616/amp/
I'm sure there's people in your surrounding area that are into androids and rooting that understand and can help you figure things out if you know any one woth a G930F/G935F INS/INU/PAK thatd be awesome. If your imei number is truly gone from your phone its should still be on the back of the phone
I know this isn't the best help but you aren't the first post I've seen of Pakistanian with US S7 tryjng to figure it out.. idk if he ever did but if you learn you can help others as well
*note: when I say change csc I don't mean flashing firmware in odin, that is impossible. I mean porting it yourself with root like in the link below this one
*another note: I am not saying use the link below as anything other than an example because again that link was developed for Eynos phones and not your snapdragon so it probably wouldn't work but just so you have an idea of csc
