My Samsung S9's sim card and WiFi(Internet) are not working. - General Questions and Answers

I have a Samsung S9(SM-G960F/DS). Actually when I got this phone, It was rooted via Magisk App. Every thing was working perfect, internet and Sim-cards, games etc. But when I tried to run my banking app, it said "Rooted devices not supported". I looked for unroot solutions on internet and most of people suggested to complete unroot via Magisk manager APP. I did this and my phone restarted after unroot. But since then, my sim-card and internet are not working. Sim-card is completely disabled and WIFI is acting in a weird way. WIFI is connected but still "!" sign appears, secondly internet is working in a very weird way again. We can only search on google but cant open any site, similarly we can search video on YouTube but cannot play any video, we can send and receive messages and pics on WhatsApp but cant download voice notes. This is the issue I am facing. If any one can understand this situation and could provide some solutions then it will be really appreciated. I can explain further if someone's willing to discuss this issue. Thanks.

How do i get messenger working on my S740

I've already posted this on the Rose forum, but i'm positive it's something fundamental ive missed on account of this being my first real HTC device.
I've just picked up my S740 and i'm trying to get it working with my Three sim card. The phone and the internet work oK, but i can't seem to get MSN working. I just get a cannot connect message.
In fact, i've even connected to my wifi network and messenger still does not want to work. There must be something simple i am missing!
I've even downloaded parlingo but it does not connect to either msn or yahoo messenger. The odd thing is that i browsed to the parlingo site on the phone, downloaded it on the phone, but when i run it can't connect.
I hope someone can help.

OK, i've worked out the problem.
There's nothing wrong with the phone. The problem is with the f*@#ed up 3 Mobile SIM which totally locks up the device and does not allow you to do anything. I suspected something was up when i couldnt install the newer Live file due to insufficient rights.
So for anyone searching for a similar issue, you cannot use this device with a Three mobile SIM. Unless someone knows how to unlock it?

[Q] Can't establish a reliable data connection to the server.

Not solved. Apparently I needed to use a VPN to connect my account though Talk. But now when my VPN isn't on nothing will sync and my gmail won't load. Until today I have never needed a VPN to log into my Google account. Something is obviously still wrong.
So I've flashed dozens of ROM's at this point and have never had this problem before. I have read all the threads and tried the following fixes ...
Pulled SIM and used WIFI
Factory reset
You Tube account ... This actually registers my Google info under accounts but won't sync at all. When I try to sync contacts or anything I get a red exclamation point and nothing happens.
Flashed other ROM's and different gapps.
Tried logging in though other gapps such as Talk and Gmail. Again YouTube will show up on my account tab as synced. It's green and looks synced but if I try to manually sync it the red error shows up again and nothing has actually been synced.
There must be a reason for this yes?
I should also mention that I'm in Shanghai. However I have never had a problem before. What gives? Why now? Could it really be that the server is down and I should just try again tomorrow?
Any advice would be greatly appreciated. Thanks in advance.
Yeah... i've been having a similar problem in xiamen for about 3 days... china unicom?
Oh? And also never had this happen before? Happened after you flashed a new ROM?
I'm with CMCC.
What makes me think something is rotten is Chinatown is the fact that if I do use my VPN everything is OK. I'm hoping this isn't the case.
I'm searching for some old TB files I can toss on my phone to try and restore it to an earlier date. If that doesn't work maybe a super crusty old ROM will work. I really am out of ideas at this point.
I wonder if getting rid of root and going stock would fix anything?
Error Message
I have also same problem for past 3 days on China Mobile in Shanghai. I belive it should be something to do with the carrier or Network accessibility to Google products... I am on Galaxy S2.
Today I checked on couple of my friends with Nexus and Galaxy S1 and confirmed that they also face same problem...
Currently the only Google app that's working is Google Translate ... The rest however won't work without my VPN on.
So it looks like this is both CMCC and Unicom so far. I don't even know if there is anything else.
The funny thing is Google + has been working on my phone from launch with no problems. Not anymore though.
Anyway there are so many places selling Android devices in China I could only imagine that this is temporary.
I wonder if there is any way to edit some of the carrier info to make things work?
Apparently there is something going on, it looks like.
It looks like it's happened before, and after about 3-4 days it sets itself aright...
Anyone figure out a workaround? I was using a pretty good VPN, but the android version only has pptp and therefore barely works here. I can't get any programs, email, or anything on my phone after a factory reset... this makes me sad.
*had some links posted but I guess I need to post a few more times before it lets me*
Anyone figure out any updates or fixes for this yet?
It's been like that for several days now...I'm with CMCC. After sometimes it'll be okay as usual....black "magic" I would call it.
VPN is a no no for me, used to work fine till they block it. I'm using SSH Tunnel now...no problem in general except from time to time (once in a very blue moon like now) when "they" cast their "magic"
Without tunneling. market couldn't get through these days.
How annoying. I even tried taking out my SIM card, and doing a hard reset, and then trying to download my software from my WIFI, but it's not a DDWRT router so I can't access the VPN.
Is there software that can turn an OpenVPN connected computer into a Wifi router? If I logged into my computer which is on a VPN, maybe I could at least re-download all my apps from the market......
*sigh* or wait heh
I got the same problem like last 5 days ...i m in China too ..with china unicom ...i tried everything possible like factory reset, uninsalling and installing gapps, install stock image , cache cleaning ....BUT ...CAN'T LOGIC GOOGLE ....
at last i used VPN on my phone ..and its sync and connect in a second ...problem gone...Happy to have my fully functional phone back
MAGIC Happened again
Just trying to log into the market .. yes now we can access the market and other google products..

phone not receiving sent links/apps

whenever i download an app via android market web store, or send a link from chrome to phone, my phone will NEVER receive it.
it has worked flawlessly before, but seems to have stopped after i rooted.
any way to fix this?
phone: nexus s
Sending links to your phone requires an app called Google Chrome To Phone. You need to start up the app and agree to the terms before it will receive links, so give that a shot, even if you feel you have done that before.
Both sending links and having apps automatically installed rely on a Google Talk connection. You'll want to also check if Talk is connected as well.

i've used chrome to phone many times before, and have uninstalled/reinstalled on desktop and phone, logged in with another account, and nothing is working! i've also downloaded many apps from android market web store with no issues until recently when i rooted.
and it worked before without me being signed into google talk.
Try to reinstall the market can work in it
You may want to make sure you can log into Talk just to confirm the talk connection is working for things other than push. But if you know that already works...
I think it's time to go back to your Nandroid backup you took before rooting. If you're using a custom ROM, it may also be worth taking a backup and going back to stock to see if that improves the situation.
Then when you try rooting again, just test C2DM every now and then to isolate the step that causes things to stop working properly.

i had same problem try to reinstall market
lol I have no idea I'd my talk connection is working or not. when i launch talk, there is a little 'x' button beside 'Offline' under my gmail account, and when i sign in, the 'x' button is still there, although i have seemed to sign in. i dont have any contacts in google talk so i cant test if its properly working.
will try redownloading market to see if that works as well, thanks!
ill save unrooting to a last resort i guess :/
update:
ive tried redownloading market, but nothing changed. when i downloaded an app from the android market on the desktop, i didnt receive it on my phone, although the button said 'installed' on my computer.
i've also tried removing my account from the phone, and then downloading an app. the market (on desktop) still said 'installed' when there wasn't any phone linked to the email...
honestly i have no idea how to fix this.

NO connectivity even after factory reboot. Big problem, need help!

Sprint Samsung Galaxy S6 G920P.02
Android 5.1.1
Rooted, No ROMS
I am very, VERY confused. This makes absolutely no sense to me. I believe my phone is just fried but I will find out when I take it into the sprint store tomorrow. I will most likely get a new/replacement phone but they will have no idea what caused the problem and I need to figure out how this happened so it won't happen again. I'm also very curious as I don't understand at all.
The problem: It started with me not being able to connect to the internet on ANY of my apps. No crashes or anything, just no connectivity to the internet. Calls and SMS still worked like normal. After calling sprint support they told me dial ##72786#, which then just simply broke calls and SMS. Now NOTHING works.
What caused the problem: This is where I am most confused. I was trying to setup a VPN (purevpn, to be exact) on my Xbox One. In the process of this, I was modifying my router settings on my Windows 8 PC, plugged in a 2nd router, and constantly turned the wifi off and on. I was using my phone to test if the wifi was still working. (e.g. going to google.com on firefox or launching clash of clans...literally that was it) The only thing that I can think may have messed it up was a step in settings up the VPN. On my computer, after I installed the purevpn software I located myself to "Network and Sharing Center", then clicked "Adapter Settings", then clicked on "Pure VPN", then "Sharing", then checked the box "Allow other network users to connect through this computer's internet connection", and lastly from the drop down menu, selected "Local Area Network." This allowed all devices on my network to use the VPN. Somehow this messed up my phone that hard?
See image below for clarification:

Steps I have taken to fix this: I tried rebooting my times a million times. Then I cleared DNS cache in firefox and tried to connect. Then I tried hard rebooting my phone to flush DNS cache. Then I called sprint support, who told me dial ##72786#. After dialing this, calling and SMS DO NOT WORK. "Hands free activation" starting running after dialing that number and fails to work everytime. When I wasn't able to call the phone rep back, I used the sprint online chat support. I told the online rep what happened, and they assured me the only way to fix this was to factory reset my phone. As frustrated as I was, I did it. After the factory reboot, my phone STILL CAN'T CONNECT TO ****. Exactly how it was before the reboot, except I lost all of my stuff. I have done countless google searches and am clueless and need help.
Google will push all your stuff back to the phone after you log into your account. But you'll need the internet for that.
How did you get root?

I really don't remember, It was months ago. I paid $30 for it though and have never had issues with it.
Just brought it into a sprint tech store and they fixed by putting in a fresh sim card, reseting the phone, cache, dns, and everything they could reset. After that did not work they flashed an updated version of my phones software on the phone, which removed the root , and fixed the issue.
I explained what I did to all of the employees in the store (I was the only one there) and they were all as clueless as me.
Does anyone know what could have possibly caused this?

Internet connection problem with the most apps

Hi, Forum,
Huawei y625 u51, android 442 here. Rooted.
My problem is with the networking user apps. All of them, besides chrome and play store, are unable to connect to the internet, having my phone connected.
So basically i have chrome connected perfectly, i read news, i read mail, whatever i want and it is all fine. Sadly, when i run skype, viber, or other user netapp, they sign me in, but do not send data and specifically give message "no connection", when there actually is one.
After i reinstall the app, it works fine. On the next day, it is all repeated - i connect and use chrome to surf, but when run skype or viber - it is to stubborn to connect i guess :d Thus i have to literally reinstall several webapps every morning after i wake up. This is a torture and irritates me heavily.
It has all begun, when i deactivated some google apps, that i dont use, in order to hide their icons from the menus. Right from the next day the above mentioned has started. I have them activated all back, but i guess the damage was already done and no solution but reinstall returns my ability to use whatsapp, viber and ect.
Any cure?
Greetings.
Ps: I have to admit, that i have pretty unfortunate experience up to now with android and i firmly believe to use it for a no further device i buy, if no major improvements are held. I feel like in a coop with it - restrictions, restrictions, restrictions.
