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.

I'm currently in Taiwan for about a week, and am trying to use my T-mobile SGSII with a Taiwanese SIM card. I got my phone unlocked before I left, and I'm not getting any errors with the SIM card. However it looks like it's not working. I'm not seeing any network signal. If I try to search for a network it says "Error while searching for networks". If I try to select a network automatically, it says "Your SIM card does not allow a connection to this network."
Anything I'm missing?
Thanks!

Well I eventually gave up on getting the Taiwanese SIM card working, but now I'm back in the states and my phone can't seem to recognize my original T-mobile SIM card anymore. I can't get any sort of network connection, and I get the same error messages when trying to change the network settings. Wifi is working fine.
The SIM card is fine, because I popped it into an old unlocked dumb phone I had, and was able to make calls with it... any ideas?
Thanks!
So it looks like my phone is stuck in flight mode, although Wifi works. When I goto Settings > About Phone > Status, the Service state says "Radio off"...
Hi there,
I have been having a very weird issue with my phone lately, I originally put a Simcard in my S3 and it happened to bend the Simcard reader pins. After purchasing a new model of the Simcard tray and getting it installed by a professional (OEM Part) It does not read my Simcard, instead it gives me a notifcation "Emergency Calls only" When putting the same Simcard into another same model (Samsung Galaxy s3 i747) It picks up a signal automatically. However, what is the weird issue is... When putting a bell/virgin simcard into my current phone it picks up a signal (Able to pickup calls & Send Messages) How can this be?
PS. I am almost certain this phone is Unlocked.
Thanks for your contributions.

Check the APN settings and make sure they are set to your carrier.

Could this be the actual issue? Since I am using the "PETRO CANADA MOBILITY" Sim/Network, And it does run/associated on the "Rogers Wireless Network" When booting up my phone it does detect a "Petro Canada Mobility" network in the phone menu after searching. However when pressing on it, it fails by saying "No Service Detected" Then quickly re-searches and hooks up to "ROGERS WIRELESS" (Also Gives me 4G DATA connection) Rogers - which is the factory setting APN setting. However, when placing a call it tells "Mobile Network Unavailable" why does this seem not to be the case when I put in a Virgin Mobile sim or Bell Mobility simcard?
I will try to change the APN hopefully this well effect the outcome. :good:
I have an unlocked t989 that I gave to my friend who was visiting me at the states. At the time in the states we put his Taiwan SIM card and it can receive phone calls. Upon returning to Taiwan the same SIM card can no longer make or receive calls. It cannot connect to any network. Try the manual and automatic network search but still cannot connect. Tried a bunch of different active Taiwan company SIM cards and only one SIM (Vibo or something) was able to connect to the network. All the SIM cards are confirmed working when used on any Taiwan phones.
Apn settings are blank except with US T-Mobile SIM card or Vibo SIM card.
I tried to use app "SIM card info" and it couldn't read any info from the SIM card except T-Mobile and Vibo.
Need some ideas as to what could be wrong. Thanks

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.
I unlocked my VZW g6 play by entering code in settings section to unlock phone (did not insert AT&T sim and wait for code request). It said code accepted but when I put in my AT&T sim I can't connect to their LTE network. It reads the sim, switches to global (gsm), and my network says AT&T with the proper phone number for that sim... But no 4g. I tried inputting the APN settings I found on several sites.. No luck. Same when I copied the APN settings from another AT&T prepaid phone I had available. No go. I called and asked for the APN settings from AT&T and they said I need to change the IMEI number on my sim to that of my g6. They said they did that for me. After power cycling the phone as instructed I still have no data service. Anybody have an idea what settings I need to use in order to use my AT&T sim? Or is that even my problem?
