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.
I came to Japan after speaking0 to sprint about the possibility of using a Japanese SIM card in my phone. They said there'd be no problems I'll just have to unlock the phone before I left which was a completely doable thing by myself without their help. Now once I set up the Japanese sim I can make calls and text but have no access to LTE on my phone. Whenever I'm outside of Wi-Fi range I get a message saying mobile data connection could not be established LTE: ESM - 30 EMM - X I've called Sprint from Japan and tried to resolve the issue, they have walk me through the same steps three different times assuring me that the phone is unlocked on their end and never with a new result. Is there something that I missing it I need to address before I can connect for mobile data connection in Japan with this USA phone.
I just purchased a brand new Xperia Z3 (D6603) and cannot get my LTE to work! I am on Giff Gaff
I followed instructions on how to setup the APN on this page:
https://community.giffgaff.com/t5/Settings-for-your-device/Sony-Xperia-range/ta-p/8630180#faq_no_1
Has anyone on GiffGaff in the UK managed to get their 4G to work?
If so, could you please post your APN settings here?
Thanks!

You have problay already sorted this one however just incase anybody else is looking for a solution here is a few
giffgaff internet and MMS settings are normally automatic and you should not need to do anything other than what is listed below: (Please ignore anything you have already tried)
1. Turn the mobile OFF and then Back ON again. (80% of all issues can be sorted by doing this))
2. Make sure Mobile (cellular) Data is enabled.
3. Make sure 3G or 4G is enabled.
4. Check you have credit and or a goodybag DATA plan (specific to giffgaff)
:: Dial *100*7# from the keypad*and press send - to check goodybag balance (specific to giffgaff)
:: Dial **100# from the keypad*press send - to check airtime credit*balance (specific to giffgaff)
Alternative solutions: (specific to android)
Toggle 3G/4G OFF and enable 2G instead then wait a while then toggle 3G/4G back ON
wifi is known to interfere with DATA (Internet) so turn wifi OFF
There maybe an issue with the 4G signal in the area check you can check the signal on the o2 service checker site
Reseting / factory restore and or messing with settings and tech APN stuff should be a last resort!!!!
Is it possible to enable wifi calling on a unlocked D6603 that has an AT&T sim inside and already downloaded the network settings?
Hello everyone,
I am from Europe, France, Using a sim card from Free Mobile. When i was in the US last week, i bought a Verizon Note 5, i saw on WillMyphonework, that it has the necessary bands to work with my network provider, and i checked the bands myself. the problem is that when getting home and putting my french sim card in, i can see the 3G, H, LTE text next to the network bars, but it is greyed out and i don't have access to internet through mobile data.
Has anyone had the same problem before ? is there a way to correct that ?
By the way, i put the apn information of my network provider, so it is not that.
Solved,
for those who have the same problem, update the apn setting then REBOOT the phone.
