Hi,
I'm new to the smartphone in general and android in particular.
I have Samsung galaxy SII i9100XXLPS.
Recently I have changed my network provider to a new one that builds its network from scratch. Mean while, the network roams to an existing network.
The problem is that although the data roaming is enabled, I keep getting the data roaming alert ("you have lost your data connectivity...") and I can't get internet.
Other people I know on the same network, some with android, others with Symbian(!) don't have this problem.
Thanks

First thing. You may want to try heading over to the S2 forum. Providing the location and carrier name, along with the rom and baseband from the phone (settings, and about phone) might help troubleshoot the problem also. I would guess though, so based on the little information you gave that the sim card is messed up, and or the phone does not support the frequencies for your carrier.

I bought my n7100 on taobao here in China, and it's a Korean version. I put my China Mobile sim card in, and it makes and receives calls, and text messages and can use wifi with no problem.
The only thing is the mobile data doesn't work. I rooted and tried tweakker, and HiNet, to reset my APN and MMS settings, but that didn't work. My phone still thinks I'm roaming.. it displays
this message "Data Roaming, You have lost data connectivity because you let your home network with data roaming turned off".
I've also tried updating the APN and MMS settings manualy with information i've found on the web.
I've googled and searched this forum and I can't find much. I thought it would be an easy APN settings fix but it seems not to be...
I took my phone in to the local China Mobile store they couldn't fix it. I took it to a local android expert here and they didn't know what to do.
Any ideas would be greatly appreciated.
If you bought a Korean Note 2, you don't (shouldn't) have an N7100. I also purchased one through Taobao.
You should have an SHV-E250S, E250L, or E250K. Which one do you have? Check the baseband version under Settings > About device page.
No matter what, you're going to be limited to 2G only with China Mobile.
You're right, It's SHV-E250S, and I'm fine using the 2g in China on China mobile, but I'd just like to know how..any help?
Baseband Version is E-250SKSVLJK
Try removing all modifications to your APN settings.
Next, go into Settings > More settings > Mobile networks > Network mode and change it to GSM only. Also make sure that Data roaming is not selected. Run a new scan for network operators while you're in there to refresh your APN settings to the right ones.
In data network mode I only have 2 options "3g only" or "LTE Preferred" I have it on 3g only. I have now unchecked data roaming, but I don't see any place to scan for network operators. I have included a few screenshots here, sorry i don't know how to insert them.. http://tinypic.com/r/2198djn/6 http://tinypic.com/r/24dhfmx/6 http://tinypic.com/r/2zof98w/6
Now it's obvious why you don't have data. Is this the stock Korean ROM? Are you rooted?
I can point you to a decent ROM that will fix all of this, provided you have the patience to fix it. It's relatively easy.
Yes it seems to be the stock Korean ROM. I am rooted using http://forum.xda-developers.com/showpost.php?p=31801060&postcount=2 I'm more than willing to flash another rom. I've put about 20 hours into this so far, I imagine I can muster enough patience to finish it
Once they give us a damn Korean Note II section, this kind of information will be a lot easier to find.
Try this ROM for now, it's the one I've been using for a few weeks and I love it.

Thanks a lot the rom (715mb) is downloading now, I have tried to flash ROM's on my old galaxy nexus, and on this note II, but I never succeeded, can you please link me to a good guide, on how to flash this rom? thanks.
Odin is included in the download. If you're using Windows 7 you may or may not have the drivers for the phone, and can grab them out of the All-in-one Toolkit. Just installing the toolkit should install the drivers necessary.

The ROM you're downloading has two files and two pictures, as well. Open the pictures and follow along. All you have to do is click two buttons, select two files, then hit start. It WILL wipe your phone.
I installed that rom you suggested, I went into settings and did GSM only, and had it automatically find my network (china mobile) selected it, rebooted, and still it says i'm roaming so there is no connectivity... any more ideas?
Can you try somebody else's SIM?
There's no reason you should not be getting service unless something is not right with your SIM or phone.
I installed the rom you suggested, i went into settings and made it GSM only, also had it automatically correctly locate my network (china mobile) and it said "registered on network".. but it still isn't working, same problem, it says no connectivity cus i'm roaming.. any ideas now?
my gf will be home from work in a couple hours, I can try her sim card then.. my sim card was cut by me for my old iPhone.. is it possible or likely that the phone can still make and receive calls, but that somehow data connectivity was affected by me cutting the card? also one guy at the phone fixing store tried his sim card (from another company) and internet worked fine he said..

China mobile have various sim plans, from local to province to national. Are you using the sim in the same city in which you bought it? If not and you don't have a national plan, it could be why the phone is showing roaming. In China going from one province to another is already considered roaming unless you have a national plan. This is from my experience back 2 years ago. Also, you best check at a China mobile shop if you have data activated, gprs/edge is not activated by default, you need to ask them to do it.
I would advise you to switch to China unicom as they have 3g/hspa which is much faster than china mobile.

For clarfication, I am in Hainan, and the card is from hainan. I use the same sim card in my galaxy nexus without any problem. I tried my gf's card just now, it didn't say any problem with connectivity, and did not display roaming.. And it shows the G symbol (for 2 or 3 G I assume), and has up and down arrows next to it.. but it doesn't actually work for browsing the web or using apps over the data network.. I even reset all the APN settings and let it automatically find the China Mobile network, but it didn't help.. what if I try to set the APN settings manualy? and any other ideas??
Showing the G symbol is GPRS, which is 2G. You will not get 3G on the N7100, N7105, or Korean model Note 2 on China Mobile.
Sounds like you need a new SIM card. You can try to set the APN manually to make the data work with hers. I've never had to set an APN manually and I've used many phones here with all 3 carriers, so it's a bit odd to me. No clue why your card doesn't work, but since hers is working fine, it's definitely not your phone.
For the record, her card displayed G, but even after messing with settings, I couldn't get it to have working data network..
Today I bought a new card, and had it officially cut to size, put it in the note II and it's still telling me no data connectivity due to i'm roaming.. i'm so frustrated
edit: after restarting a few times and trying to automatically make it register on china mobile .. it worked on the 4th attempt.. it still displays data roaming, and I had to enable data roaming... but now it works, even though it says i'm roaming?? wtf
Ive the same problem with my Korean galaxy note 2 all voice service work perfect but when I tried to turn on data it says insert Usim Card to access network please help
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. I'll simply explain what happend.
I went by plane. I switch my phone on to airplane mode, but when I switch it back phone can't connect to my home network.
It detected networks and can connect to the internet but I can't make any call or recive it (the same with SMS).
It show Me the error message - Mobile Network Not Available or just simply Call ended after two beeps signal.
Show me yellow triangle on the top notification bar and message - No service, Selected network unavailable
I checked IMEI - it's correct
I used PC Companion tool to Repair My Phone - doesn't help
SIM card work well in other phone
other SIM cards - the same problem - not working (I even tryed SIM card from different country network operator).
Phone has no SIM lock
Back to factory settings doesn't solve the problem.
Any ideas what going on with my phone and how to fix it? Please
Model: D5503
Android version: 4.4.2
Build number: 14.3.A.0.757
So it did work before in your home network?
Or is it an issue with a new phone?
Sounds strange to me... If your SIM works in other phones, it can't be a provider issue.
I can't imagine that it is a software issue since it keeps happening after a factory reset.
If it's the hardware it is a warranty issue...
But maybe somebody has a suggestion for you.

I had some unusual problems with an inability to xfer data over the mobile network (as opposed to the WiFi) on my wife's Z1c, after both had been fitted with what seemed to be brand-new sim cards by the local T-Mobile store, and I found that in:
*Settings
*Wireless & Networks: More
*Mobile networks
*Access point names
...that she (somehow) had an access point name of "epic.t-mobile.com" as opposed to my APN of "fast.t-mobile.com"
So, I deleted that, and selected "create default APN", and fixed the problem.
There are other settings in that same menu, such as "preferred network type" that might be messing you up.
She could make calls and send texts with this problem, but had no internet unless she turned on WiFi.
But I cannot imagine what would be re-provisioned by switching airplane mode on and then off.
Perhaps you need to declare your sim card a dead parrot, and get a fresh one from your service provider.
This is pure speculation, I have no evidence or experience, just guessing at things that MIGHT cause such a symptom.
Hi Team,
I have purchsed a brand new Xperia Z1 from a retail store.
I am having problem with mobile network connectivity, its not behaving in normal manners.
Many times it drops network and many times it gets auto switch off in a single day and I need to restart it 2-3 times in a single day to make it work properly.
Many times it happens that its showing full network strength and when somebody calls me it says that this number doesn't exist, this is not a simcard issue as my sim is working perfectly when I use it in any other mobile.
I have already given it to sony service center two times and they use to say that softwer was required to be updated that's why you were having network problem but its not resolved yet.
Its is very costly mobile phone and as of now I can't afford to buy any new phone as I have spent my whole savings to buy this phone.
Can you please help me?
Thanks in advance.

Solution:
I struggled for 2 days to resolve this. And the solution was so simple. I resolved the issue accidentally.
Besides following all the recommendations (except the hardware part) on different online forums I was exhausted. Doing nothing, I started making a backup of my cell phone with an idle mind. And there I found an option to reset your network. I have Sony Xperia Z3 Dual. You should try this.
Go to Settings -> Back up and Reset
Scroll down
Go to "Network Settings Reset".
Then reset your cellular network. And bingo. It worked for me. I was able to make calls and use my cellphone in normal mode.
Please let me know if it worked for you. I can guide you for some more tricks.
Hello, I bought and unlocked a HTC M8 but now I have put my sim in everything apart from there is no data connection, Wi Fi works but not data. When I go to Mobile Data in settings it says "disconnected" and when I go to APN it says " Access Point Name settings are not available for this user" Is this the problem ? Can anyone help figuring how to data connect ?
Thanks
Have you selected your network operator first.

This is one of those things that can be most easily solved by calling your operator. When I got my phone and put in the sim card, I had no data. I called O2 and they guy walked me through the setup. It might be a noob way to solve problems, but it definitely works.

It did not matter for me. I have an unlocked phone and a sim card from O2. O2 is providing me with the service, it's their job to make sure it works. My phone was brand new, so it would be safe to assume that there was nothing special about it. Also, here in Germany I can always return the sim card and void the contract within two weeks after buying it, so the network wants to keep me happy .
