I just received my unlocked ATT S3, rooted it, cut my sim card down and setup all my apps etc. Problem is that I am having really sporadic network access issues. I am currently in Afghanistan and using AWCC. I had the same sim card in a Skyrocket and didn't have any issues. I have setup the APN (I pay for unlimited edge internet) and randomly get internet access and network access.
Right now I show 3 bars
Info shows
Network: AF AWCC
Signal Strength -89dBm 12 asu
Mobile Network type: Edge:2
Service State: In Service
When I try to check my balance (*123# dial) It says connection problem or invalid MMI code EDIT: sometimes it goes through and I get my balance.
When I try to make a call it just says dialing then goes to Call Ended after about 30 seconds. Same thing happens when I try to call AWCC customer service at 151 (actually I just got through on the 151 number once)
When I go to Settings/More Settings, Network Operators and try manual settings, about half the time I see the awcc network but it always fails to connect. If I leave it is automatic, it will eventually connect. Right now it is showing AWCC in the top menu bar. Other times it says not registered on the network. FYI AWCC doesn't register the sim card to a specific phone. You just buy the sim card without giving any info about your phone.
Every once in awhile it connects as I received emails on the phone over night. As I am typing this I just got edge connectivity and am online.
So, anyone have any suggestions? Maybe I should try flashing another modem?
Thanks

Hi.
Galaxy Nexus, 4.2.1, bot unlocked from amazon about 6 months ago.
On dec 2nd signal just went off. So no calls nor receiving can be done. While mobile internet is still ok.
Network is giffgaff, running through O2 - UK.
Taking this sim to other phone - works fine.
Support from giffgaff said that everything is perfect on their end.
Putting any sim in this phone, shows same issues - no signal, but there is mobile internet.
Checked status of IMEI, and it says in online services that phone is unblocked.
I have tried on/off airplane mode, restarting, taking battery off for a while, with sim in and out, as well did factory reset - still issue is here.
It is unrooted, just original rom.
Going to settings > mobile networks > network operators > I select any network and it says: "Can't connect to this network at the moment. Try again later.". Same when choose automatically.
It allows to do emergency calls, and in status bar shows: "emergency calls only | giffgaff".
In About Phone section, network is "O2 - UK" as suppose to be, Signal strength "-101 dBm 7 asu", mobile network type "HSPDA:8", service status "Out of service", Roaming "Not roaming".
Please ask any questions if any additional information is needed.
King regards.
I am looking forward to anyone to try assist with this issue, and kin to help.
Contact your operator for change your sim, it happens to me this summer, my Sim card was working well with other phones but with my Gnex everything was disabled. Then I've received my new Sim card and everything is working well

Then other SIMs would work well. But inserting any SIM in this phone - doesn't work for calling. Only mobile internet.

Based on this info, I suspect your radio simply died. You could of course try to reflash the radio firmware yourself, but I would not get my hopes up.

Thanks for info. I thought about that as well.
So would it be the option if I have bought the device from amazon, to use their RMA services - they should replace device.
Is that right?
Thanks for helping out.
Hi Guys.
So received the phone on Thursday, Friday I did a sim swap from my normal sized sim to a micro sim. I waited the whole day but the phone didn't have any network access.
Today when I woke up I I switched the phone on hoping that everything will be fine, thinking the simswap just hasn't gone through yet, still no network access. I took out the swim from the phone and switched with my ipad, the sim was working in the ipad, and the ipads sim also didnt give the phone network access.
In the top right corner it shows full bars in grey, cant make emergency calls or anyhting.
In the about section of the phone, I have ALL the details present, baseband version is there, kernel version is there.
In Status section, network is unkown, signal strenght is -83 dbm 15 asu, network type unkown, service state is out of service, and the rest is also present.
I thought the phone didn't properly register to a network, so went into settings - wireless networks - more settings - mobile networks, but it gives me a insert sim card message.
The phone is reading the simcard fine because it asked for the PIN when switching on.
When trying to make a call I get, it says "Not registered on network"..
So what am I to do? Vodacom can only pickup the phone and exchange it on Tuesday, so was hoping that this might just be a software issue that can be resolved by a flash.
I have tried resetting / hard resetting the phone numerous times.
Its the Note 2 N7105 LTE Version
Any help would be highly appreciated.
Wrong forum.

Great thanks.
I tried this but didn't solve the problem. I am using the same sim that I received from the carrier with the phone they shipped.
I have played around in the menu however, maunally setting the band and so forth, just restarted and started receiving sms, so basically if not for your post I would not have solved this.
Thanks
I have isolated the problem.
In the service menu - UMTS - DEBUG SCREEN - PHONE CONTROL - NETWORK CONTROL - SERVICE DOMAIN
There are 3 options
1 CS + PS
2 CS ONLY
3 PS ONLY
CS seems to be for making calls and sending smses
PS seems to be for data connections (When this is selected, the bars are replaced with a circle with a stripe through)
I Could be wrong with the above, so anyone with experience please shed some light
Those 2 work seperately, but when CS + PS is selected, none of them work? Very odd, anyone know what the issue could be?
anyone?
Its a unlocked TMobile samsung galaxy S2 (SGH - T989) from US which I am trying to use in India. I had bought it from t-mobile as part of a 2 year contract. After completing my two years contract, I got the phone unlocked from t-mobile before coming to India. The phone worked fine for first 15 days here in India but stopped working since then. I have tried many different SIM cards from different Indian mobile service providers. These SIM cards work perfectly fine on other handsets . *#06# shows correct IMEI which matches with what is printed on the back side. Phone shows signal towers with varying signal strength. I could see the signal towers even after disabling Wifi and location services but when i try to make a call, it says "Not registered on network". Wifi, if enabled, works fine though. When I try to select a network operator from Mobile networks menu, it does say registered to network occasionally but mostly it fails to connect to any network (i have tried both manual and automatic selection) but even if it says registered to network, when i try to make call, it says not registered on network so I am not able to make any calls at all. I have tried factory reset and upgraded to JB 4.1.2 (radio: UVMC6) but problem still stays. Please help me.
Did you try entering the correct apn ? Similar thing happened to me but i took it to the sim card company and they entered the apn manually and it worked.

I did try APN but I believe that is for GPRS/EDGE and 3D and these will take effect once cell network is established.
Hi All,
I have a Canadian T989D from Koodo mobile which I unlocked using unlock code. I took it abroad to Pakistan and after using for 6 months, one day all of a sudden I got NO SERVICE.
Trying to manually select networks, I come across different networks available but clicking on any one of them results in NETWORK REGISTERED sign but still doesn't connect to any network. When I go into the APN settings, I can see different APN settings for the respective sim cards that I put in. E.g. If I put UFONE sim card in, I can see APN settings for UFONE SERVICE PROVIDER.
Here is the twist though. I came back to Canada yesterday and when I put any Canadian Sim in it (FIDO/VIRGIN), it connects to the network without any problems.
Next, I tried T-Mobile sim in the phone. At first few attempts I would receive NO SERVICE/EMERGENCY CALLS ONLY messages. However, just recently I was able to connect to the network by repeatedly changing sim cards and restarting the phone.
So the specific questions to all of you is that "Why can't I connect to ANY network in PAKISTAN when I can see the APN settings for each sim card I put in?" Is there something I can do to fix the issue? I have a running sim card from PAKISTAN with me which I had previously used to connect to the network. Please help/guide me.
Any response will be greatly appreciated.
