I have a unlocked Samsung SGH-I747 from ATT its mobile data tethering is not working. Error message "Mobile data is not available or invalid SIM" appears. I have rooted the phone with SUPERSU. I am a amateur at this I rooted the phone following instructions on youtube and xdadevelopers. Its working fine otherwise.
Could someone help? I don't have internet at home and want to use the simcard to connect. I am using a simcard that allows tethering on a normal smartphone. No problem with the simcard.
Thank you for your help.

Hello Everyone, I am using Samsung Ace s5830i and since yesterday I am not able to make any calls, when I try to call a number it says "Mobile Network not available" but I can see good signal strength and I am also able to use GPRS. In the notification area it says "Emergency calls only".
I went to Settings -> mobile networks, when I try to manually select my operator(TATA Docomo, i'm from India) i get the error "Your SIM card does not allow a connection to this network".
I have removed the sim card, inserted in another mobile, it works fine. When I try try to insert a sim card of some other operator into ace I get the same errors listed above.
These are the things that I have tried.
1. Removed the sim card, battery inserted them back and restarted the phone
2. Restored my Nandroid backup
3. Complete factory reset
None of these worked and still I get the same error.
Information regarding the phone:
Model- Samsung Galaxy Ace s5830i rooted with CWM 5.0.2.6
Android version - 2.3.6
Mobile network type - GPRS
Network- TATA Docomo
Signal Strength - -90dBm
Service state - Out of service
Mobile network state - Disconnected
IMEI - Unknown
I have called Network provider they say fault is with the phone.
Any help would be really appreciated...

you have lost your IMEI... u'll need to flash stock firmware via odin!
see this thread for procedure!

Re: Help "Your SIM card does not allow a connection to this network"
Just for the knowledge, what may be the reason for losing imei and does flashing stock rom retrieve my imei.
Sent from my GT-S5830i using xda app-developers app
possible reasons are many...i don't know what files did you flash? (Rom/kernel/scripts)
Cronmod script is known to have this issue...did you flash this script?
Flashing stock rom with odin will give back your imei!
What's your ROM/kernel? and what scripts did u flash?
Re: Help "Your SIM card does not allow a connection to this network"
I am using stock rom. No i didn't flash cronmod script. I'm not sure but i think problems started after installing Online Nandroid backup tool maybe it has installed some scripts, i'm not blaming the tool it is fanastic app to make nandroid backups.
Let me flash custom rom, hope problem goes off.

Please make it @ proper section
Hello guys!
I bought a Samsung Galaxy S III GT-I9305 from a friend.
Unfortunately my network doesn't work, First of all I thought that my telefon is locked. I downgrad with Odin to jb 4,1,1 and after that I unblocked my telefon with dialing the following keys *#197328640#. I checked IMIEI code and it's not blocked.
I have the same problem after unblocking, Before I unblock my phone I start it once and I could call one of my friend just for checking if it works and it did but after 30 seconds it disconnected from the network and I see at the top of the window that there is no connection and there is a "block icon". I tried to scan manually for find the network and tried to connect me to all of them but it doesn't work. When I try to connect me manually to some network I get this message (!) : "Selected Network (name of the network) unavailable". the strangest thing is that I tried to connect me to the internet and it works. I can surf the web but can't make or receive calls. When I try to call some one I get this message: "Mobile network not available."
Where is the problem?
What do you suggest that I do?
Thank you!
Suggest you post I9305 questions in the I9305 Q&A
usual reply to your question.
IMEI wrong .
Modem Wrong
CSC Wrong / APN settings wrong
NETWORK problem
SIM problem

How much do you trust your 'friend'? Do you get to browse internet on wifi only? I'm thinking your phone is locked due to being stolen. They block the IMEI so no network will work for you, but a wifi connection would still work I think as it doesn't bother with IMEI but issues an ip address.
But try the 9305 forum for Help and Troubleshooting - maybe it's a 9305 issue?
Hi Ladies & gents,
I'm new to this forum, and new to android.
Basically i was given a Samsung Galaxy ace by my brother (was on o2 network, all working fine), and i decided that i wanted to try & unlock it.
In the process, i rooted the phone successfully, and downloaded galaxy tool box, to unlock it. This was all carried out using an sd card from my pc.
After the procedure i changed sim to 3 network, and found the phone saying "no network coverage."
I checked the settings, and under mobile networks\network operators if i click on search networks, "searching flashes up for a second and thats it!
If i try select automatically it says "unable to connect to network. Try again"
The phone shows 3 out of 4 bars signal, and when i try & call someone it says "no network coverage."
Have i goofed up, as i now have a phone that works fine on wifi and everything else except to make non voip (skype etc) calls!
Please help?
Thanks in advance.
Chek your imei num.
If not there fix it with HEX EDITOR. Your network connection wiil be start.
Hit thanks if I help

Hi,
so I have an unlocked AT&T G850A that I'm using on T-mobile. When I tried to enable the hotspot, it gave me an error "Mobile data is not available or invalid sim card'. After long research, I learned that i need to root the phone and replace a file. I searched all over the web, but couldn't find root files for the G850A.. I'm currently using PDanet to connect to the internet using a USB, but i really need to get the wifi hotspot working.
IF anyone knows any solutions please let me know.

I am in the same situation but I dont need hotspot on this phone. I remember someone telling me it cannot be done if you are on KK 4.4.4.
But once you update to Lollipop, then the Hotspot will work on T-mobile. I read someone. Maybe someone can confirm.

See I can't even do that because I have a t-mobile sim card, and it won't let me update unless i have an AT&T sim card.

SM-G850A AT&T Unlock Issue
Hello,
Hope you guys are doing well. I followed the above thread and re-flashed the firmware as recommended. However when I try to enable the mobile hotspot functionality it states that I must contact att to enable hot spot functionality. My carrier is straight talk. I just wondered if they are locking the tether functionality at the sim card level? I was planning on using the hotspot with pda net. I will mention that I left the EFS partition entact since it contains me IMEI info. Not sure if I needed to wipe any other partitions before I flashed this firmware. Thank you guys for all the help.
Thanks,
Coop
How to Hack Your Samsung Galaxy Alpha SM- G850A into a Free Wireless Hotspot even it is unlocked from AT&T?
Hello Guys,
I have a Tmobile s6 edge. I have unlocked it to use in Brazil. Everything was working fine but I had a trouble with root and ended up soft bricking (not passing the Tmobile logo screen)
I managed to reinstall Tmobile stock rom and make it work again. All was fine but this afternoon the phone decided not to register on the network anymore. Weird thing is that I still have connectivity over 4g. I tried a Tmobile Sim card and get the same problem.
Any suggestions? Should I root it and flash a custom rom? Different radio? Everything else is working fine.
Thanks!
Turned out that the imei was blocked. I managed to change it through a company in the US. Now it's back to normal.
Go to settings > mobile networks > network operators and select search automatically.
If this doesn't helps then tap on search networks and select manually,this worked for me.
