I am a Canadian who had a working Canadian phone plan. I am traveling in South America and I had canceled my Canadian plan and removed my sim card. I have been traveling in airport mode. Yesterday I tried to buy a Colombian prepaid sim card/plan. The phone was unable to scan for networks. The top right icon is greyed out, in settings about phone network mobile network type "unknown". Mobile Network State "disconnected". I have already done a factory reset.
Please suggest solutions.

We all know that there's a setting called "data roaming" or "use mobile data while roaming". I'm wondering what is considered "roaming" to the phone? And how does the phone know it's currently "roaming"?
My guess is, the phone considers itself being roaming when the network it picks up is not the default network specified by the SIM card. For example, if I have a Rogers SIM and I travel to US where Rogers network is not available but only AT&T network is available, the phone will pick up AT&T signal, and thus the phone considers itself as "roaming"?
Is my understanding correct?
it's defined by your SIM card not the phone
once you jump carrier you are roaming
Hello I have an odd problem. I have an unlocked ZL which has been working fine on AT&T in the US. I travel to London a lot and have the international data option on my account and has always worked fine with my other phones. However after arriving in London my phone is stuck on Everything Everywhere (EE) and they don't have a roaming agreement with AT&T. This would be an easy problem to solve by manually selecting a different network but this is my problem. On my phone network selection, below, APN is not showing up. I originally thought this may have been disabled by the original network (Indonesia I believe) so I flashed the US generic firmware and Nordic but nothing I do makes it show up. Anyone else have this problem or solution?
Thanks

Its DISABLED by your AT&T sim not the phone. If you notice by putting another Sim (Non AT&T) You can then use network search. Also ANY AT&T Branded Phone Network Search is LOCKED. I know your ZL is not AT&T branded but your SIM is which is causing it to lock it. My disapers when using an AT&T Sim, But when putting a T-Mobile USA sim or Orange UK sim BAM Network search shows up..
Also I think AT&T has Agremeants with EE , as EE can roam on AT&T here in the USA, EE is basically ORANGE UK, If they did not have aggremeants your phone WOULD NOT connect to the network. Make sure your data roaming is checked..
Thanks you are correct. Crazy considering they wanted me to manually select a network other than EE.
They're support is sometimes ehh. If they had never been out of the county they probably won't know. How is it over there . Always wanted to go.

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.
im obviously on tmobile
and at my work i have barely any service there but a coworker has verizone and has pretty good service
in the settings app under mobile networks there is the Network Operators i click search now and it searches for a network
AT&T and Verizon usually pop up
i try to connect to one of those and it say unable to connect try again later or unable to select network select automatically
anyone know the problem here? do i need to be unlocked? is it the apn settings? do i need to turn on data roaming?
thanks
No one?

You have a T Mobile Sim card and will only connect to T Mobile towers.
You would need to swap and activate an AT&T Sim card to connect to AT&T.
Verizon is CDMA so very different network.
