I am currently in Italy using a Vodafone UK sim card, it's been working perfectly (apart from randomly dropping complete signal periodically) but now it's just completely died, as in it won't find a signal at all to connect to any network let alone data roaming. I have contacted Vodafone who said there's nothing wrong at their end and the worst thing is it was working perfectly till this evening. So now it sometimes says emergency calls only or just the ring with a line through it as it cannot find any signal at all. I have tried doing manual network operator selection and automatic but still nothing... Any ideas? It's a g9550 128/6gb
Update I now have 3g data but it says "no network connection" and I cannot send receive texts or phone calls, yet I have full data...

Consequences of buying a CN/HK variant....
They usually have network connectivity issues, not surprising. Try removing the SIM card, turning the phone off, wiping cache in recovery, insert the SIM card, and then reboot. Then manually go and search for a network in settings and force it to connect to Vodafone Italy, should work.
It's working now again, I didn't do anything lol it just started working on its own accord! I'm now in Switzerland and all is good. My life is empty without my phone
It always happens to me when abroad. I am on O2. I have to select network manually and pickup different to the one which auto connect shows emergency calls only. Looks like some cells allowing me to connect but won't pass through calls
Do you also have a usa/china variant?
No, o2 UK from Samsung

Hi,
I have a Nexus S I9023 with baseband I9023XXKI1
Provider is Telenet in Belgium, which is a full MVNO with its own MNC
When running any Gingerbread version, the phone works fine when going out of the country, and returning.
But with any ICS rom (stock or CyanogenMod) the phone will not be able to connect to any international providers, when my providers SIM is installed. But when I stick my providers SIM into another phone the SIM will switch over, after which I can put it back into my Nexus S and I can roam to any other international provider without problems, but the phone will not switch back to my own provider when I get back into the country. At this point I again have to put the Telenet SIM into another phone to force it out of roaming mode after which I can put it back into my Nexus S and it works again on my own provider.
I also tried with another Telenet SIM and had the exact same problem, so it is not a problem with the specific SIM itself. But when I stick in a non-Telenet SIM it does switch to roaming and non-roaming without problems. So it clearly is a combination of the ICS ROM with the Telenet SIM.
The only other thing I found is that the MNC code in apns-conf.xml is wrong for Telenet. It is listed as MNC=10 which used to be correct until sometime last year when everyone was issued a new SIM with MNC=05. But with a custom APN setup mobile data works fine.
If anyone has any idea how I could solve this issue, I would love to hear about it!
Cant Activate/Deactivate International Call Roaming on Nexus S.
Hi,
Same issue here, mine is Nexus S, running ICS 4.0.4, baseband version I9020XXKI1. I am not able to make calls in roaming. I spoke to my provider (O2 Germany) and they say that, I have to deactivate the lock (Lock to activate roaming). I haven't found any way to unlock this service. I have not tried what the OP has mentioned in his post (i.e., to put the sim into another phone and then try back in Nexus S). But I would like to know, how can I Activate or Deactivate the roaming lock ??
Thanks,
Cheers!!

The only roaming feature you can enable is for Data. This has no effect on roaming for normal phone usage.
You can change this setting under "System Settings" -> "More..." (under Wireless & Networks) -> "Mobile Networks"
Here you will find a "Data roaming" option, and possibly a "National data roaming" option
I have a Desire Z with Android 4.0.4 and Telenet for the cellphone also. I noticed I have to activate the romaing in Belgium to have the data connection which is strange as I'm in Belgium. Now I hear that they can be issues calling/sending sms abroad... I'll see when I'll be in Croatia.
I activated for the moment all the option (data roaming, national roaming) for the moment, nothing more strange than having the romaing activated and the 'R' in the network signal.
National Roaming seems to be needed on some phones, since the Telenet SIM swap last year to get a data connection in Belgium. On my own Nexus S phone I don't have the problem. But on my wife's SE Xperia Mini Pro (2011 model) with stock Android 2.3.4 it does have this issue.
The old sim used MNC=10, while the new SIM uses MNC=05 and it seems that some phones have some kind of issue with that.
MNC is the Mobile Network Code, which together with the MCC (Mobile Country Code) forms a identifier per provider.
http://en.wikipedia.org/wiki/Mobile_Network_Code
I narrowed down the issue somewhat.
Basically my prior workaround that the SIM needed to be swapped to another phone to force the network to connect was false.
What actually needs to happen to force the phone to enter or exit roaming is to pull the battery.
Rebooting the phone, or shutting it down and rebooting (cold boot) does not make a difference, the battery needs to be pulled and then the phone will switch networks.
I found this by accident, because I was out of the country and it was as normal refusing to switch to roaming mode. Then the battery died and I connected power to the phone and booted it, and it suddenly connected to a foreign provider in roaming mode.
Getting back to Belgium, it again refused to switch back, so I verified it by just pulling out the battery and putting it back and the phone successfully was able to connect to Telenet again.
In other words, some component needs to be reset for it to successfully switch to roaming and back. This component does not get turned off when the phone is turned off, so the battery needs to be pulled.
Hi,
I have H60-L02 version with B307 from some time now and lately I noticed that, without warning, one or both sims are been disconnected from network, putting me in the situation in which I cannot make or receive calls. If I change from 2G to 3G on sim 1 it reconnects.
The fact which is more annoying is that in disconnected state on the status bar it shows that I have network signal on both sims. For checking if I'm effectively connected to network I have to go in "Settings-About phone-Status-Network" and verify the Service state.
Anyone had this problem, and if so, is there a workaround ?
Thank you.
I got similar problems with the SIM card. I've got the international h60-l04 on stock firmware with one SIM slot and the mobile connection fails every time. The Status Bar says there is a connection, but it isnt stable. It switches every few seconds.
I tried to delete the APN, forcing 2G and 3G and havent got a sollten, yet. I first thought it's a firmware failure.
Is there any solution for this? I have the similar problem as well... My model is H60-L02.
Thanks..
Hi folks,
This is my first post on here. I'm having a problem with my phone which I think is quite unique and I hope someone on here can help me fix it before I buy a new device.
I have a galaxy nexus (maguro) running cyaogenmod.
Previously I was running CM11 (cm-11-20141115-SNAPSHOT-M12-maguro) from the CM website and updated it to CM12.1 cm-12.1-20160719-SNAPSHOT-YOG7DAO8DL-maguro) a few weeks ago.
When I rebooted my phone it was running very slow (and getting very warm) so I did a factory reset and re-installed CM12.1.
It started working ok but I noticed that my phone was displaying 'emergency calls only' even though the network reception in the status bar was full, displaying 'H' (3g) and allowing me to connect to the internet using 3G.
Whenever I make a call it states 'Mobile network not available' and I cannot send text messages.
I tried phoning O2 and they gave me a new sim but the problem was still happening. I then tried putting my girlfriend's EE sim into the phone and I could make calls/send messages. I also went to France on holiday and could use my phone to phone/text using my O2 sim abroad. Whenever I put my O2 sim into another phone I can make calls and text.
So basically it is only when my O2 sim is specifically in the Galaxy Nexus that I cannot make calls/send texts but can still use 3g.
Oh yeah when I go to Settings>Mobile Network Settings>Network Operators the following available networks are shown:
O2-UK
T-Mobile UK
3 UK
vodafone UK
Orange
When I select O2-UK is states 'cannot connect at this time. Please try again later'
I've tried re-installing the older version of CM11 and today I tried wiping the entire phone (internal sd card etc) and it is still happening. Can anyone help? Is there something else I can wipe, or setting I can change?
Thanks in advance
Hi
I'm having a strange problem with my new A51, with two SIM cards in it.
After an indeterminate time the phone disconnects from cellular network.
It still shows on to the both cards the signal strength, but the phone no longer receives calls or has internet access throw cellular network.
And if I call any of the SIM card numbers from another phone, I get a network message saying the phone is disconnected.
All other functions on the phone seams to be ok. Turning wifi on and off has no effect in reconnecting to the cellular network.
But... If I try to call from A51 to any other number, the phone reregisters on cell network, the call is done and from that point on, all goes to normal. I can receive calls again and access the internet using the cellular network...
I went to the store were I bought it, and the gave me another one, but with the exact same problem.
So I believe is not a hardware problem.
I believe now that It could be a SIM problem, on one or both SIMS, which is odd
A software problem on A51 the need's to be patched, which is odd because it has effect on the most basic feature of the phone, which is receiving calls...
A strange behavior of the phone with my cellular service provider, which is odd too...
I'm trying now with only one SIM to see if the problems happens too...
Can any one suggest any other test or debug to try to clarify this issue ?
Thanks

My wife have exact same issue with single sim.
I have a network issue with my OnePlus 8T. Whenever I enter an area that doesn't have great signal, if my phone connects to 4G, I completely lose all signal and the phone will read "No Service" or "Emergency Calls Only". The best thing I can do is toggle Airplane mode or restart the phone to fix it. The issue does not occur if I set my phone to 2G/3G only. My phone will have signal absolutely everywhere, there isn't a spot that I know of that doesn't get reception. However, the moment I tap "Mobile Data", if the phone connects to 4G and the signal isn't 50% or better. My phone just loses all network on the spot and refuses to return unless I do the two things I listed above. I've been in contact with my service provider, tried swapping SIM slots and cards, reset my network, verified APN is properly setup. Just about everything by now. Does anybody know of a possible solution to this?
