[Q] Network/Data Connection not working with overseas SIM - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I have this problem occurring which I don't understand how to fix. I'm currently overseas in the Philippines and I'm using a Globe SIM Card though I'm not getting any network connection, my data bars are completely grayed out showing though it's full but it shows no signal type next to it. I know for a fact that my phone is unlocked since I am able to call and text using the SIM I have, but I just can't get any internet connection. I am running Resurrection Remix ICS Final Version (which I believe is: v2.7). I'm running on a Siyah Kernel and my Baseband/Modem is I9100XXKI4. Should I return to stock in order to fix this? Or change my modem/baseband or flash a more updated ROM? Any suggestions?
Thanks.

I think it could be a problem of the modem or of the rom,
this summer I was in greece with a greek sim using cm9 with its stock kernel and I hadn't any problem with data connection

Check your APNs while the Globe SIM card is in.

What I meant, was are they set correctly for the local carrier you are using while you are in the Philippines?

Thanks so much! I did a quick google search on the correct APN settings for GLOBE seems some of them were incorrect now it's working good! Do you know which modem/baseband would be best suited for GLOBE or Philippines?

Connected to carrier but signal says Roaming, no APN settings, but have internet

OK guys the title explains my predicament. I live in Costa Rica and am currently with the I.C.E for any of you that may be from here. I purchased a used S2 from a guy that bought it from Claro. So the first thing I did was get rid of the stock and I flashed everything like I wanted which is:
CheckROM v6
Using DarkKnight's Kernel
I'm using the KI3 radio but I have about 20 others and none of them changes my situation (coming up)
Original info was:
PDA-KG7
Phone- KG4
CSC - KH2
NOW here's the deal, my network icon has full bars but with an R for roaming. The phone works fine, I somewhat have data connectivity although SLOW, BUT when I go to APN settings there is nothing there NOR will it let me save a new APN, BUT I do get the 3G and H icons depending on where I am, I just can't program in a new APN or get rid of the Roaming icon no matter what ROM I flash, kernel or radio combination...
I have tried automatically and manually selecting my networks also, no dice...
I have of course already gone to *#*#4696#*#* and changed settings and tried all the variants but currently have it on WCDMA preferred.
I have also gone to *#2263# and tried all those variants but left it on WCDMA All Channels.
So I am more than open for any suggestions.
Go to Sammobile.com & search for stock firmware for your country/carrier (or just your country if they don't have any carrier specific firmware for your region), flash this firmware via Odin following whatever instructions Sammobile have for firmware downloaded from their site.
Once you've done that, check your APN setting & see if you have full connectivity. If for whatever reason your APN settings are blank (if you only end up downloading/flashing a country specific firmware only, for example), call your carrier for the APN settings and then enter these manually.
First thing you do when you have these problems is go back to stock & see if you can reproduce the problem or whether going back to stock fixes same

Thanks alot for your response MistahBungle.
Well on stock firmware is where I originally have the problem, that's the reason I began flashing ROMs and radios. IF I use a SIM from the original carrier which is Claro then all is well. BUT if I use a SIM from one of the other two carriers then the phone signal says roaming and I can't save any APN settings, no matter if I'm on stock firmware or any of the other ROMs or radio combinations that I have tried.
OK. Looks like we'll have to dig a bit deeper
So do you have baseband & IMEI in settings/about phone ? That issue of not being able to save APN settings with those other carriers sounds to me like a SIM or network issue. My first thought was it's a problem with the baseband, hence I suggested to flash a stock rom. But if that was the issue, you probably wouldn't be able to enter APN details for any sim/carrier.
Actually, now that I think about it. You know what it sounds like ? That the phone is network locked to your original carrier. That would explain everything.
If your phone *should* be locked (like you're on a contract where you only 'own' the phone at the end of the contract, etc), then I guess you can either pay the original carrier to unlock it. Or you can try one of the many unlock methods you can read about on here/apps you can get on the Market. Or if it shouldn't be locked yet it is, maybe ask the original carrier to unlock it.
You could also try flashing a specific rom for one of the other carriers, but I'm pretty sure that phone is network locked.

Ok just to clarify... all that makes sense, but what is ODD to me is that I don't think the phone is locked... I have full phone capabilities. I can make and answer calls, send texts, I even have full internet capability (even if I can't save any APN settings and there are none to be seen in the menu to choose from), I have the full speed of what I'm paying for from my carrier... the phone just won't let me SEE what APN settings it's using and in the signal it says R for roaming, but in networks it shows that it's connected to MY network...
Yes my IMEI does come up, BUT when I try one of those unlock apps I always get the message that it was unable to unlock it, but it's working with my carrier.
Ahhhh. OK. Yep that's a bit clearer now
OK. So we're pretty sure it isn't locked. That is really weird that it won't let you enter APN settings (regardless of which rom you're using), but you still have internet connectivity. Again, showing your network as the network connected to, yet showing up as roaming on the taskbar, is weird.
I've gotta say I"m pretty much stumped then. Haven't read a similar situation on here in the 4 mths I've been following the Q&A section of the board pretty much every day. Sorry I can't be of more help
Hopefully someone better qualified that me reads your post & can help. If you don't get a reply in a day or two, give it a bump.

Hey don't apologize, as you see no one else has ventured to give me a response either and I'm completely stumped myself. I looked for 5 days for an answer before I started a new thread because no one will go off on a noob for not searching quicker than I will, but I just haven't seen anyone with a similar situation on any forum anywhere...
THANKS AGAIN!!
Now to the rest of you devs, come on help a fella out and tell me what files I need to be looking for or modifying
Ok MistahBungles I got an update for ya... I decided to download a different firmware package (the PDA and Phone match mine but not the CSC), it's for Claro Argentina, BUT the ROM isn't branded when I booted it (the ROM the phone came had a CLARO boot logo (another reason I started looking for a different ROM)) and THIS ROM automatically has my APN settings in the menu without me doing a thing and the R in the signal is gone....
So now my question is how do I go about flashing the ROM I wanna use which is CheckROM but not lose my new found freedom (I ask because I'm not sure if this is a simple radio issue)

The Phone maybe Network Locked.(Not sim locked) As taken from gsmlocker.com:
Q. What sorts of locks are there?
A.
- lock phone to SIM
- lock phone to OPERATOR (network lock)
- lock phone to CODE (product lock = offer lock)
If your phone is locked to the sim you cannot use any other sim than the one you have: SIM broken makes phone useless.
If your phone is locked to an operator, you can use any SIM from this operator in your phone. You can switch between contract and prepaid as you wish, but not to a different operator.
If your phone is locked to a code, the phone checks a special "password" (GID) on the SIM that must match your phone. Providers often use different passwords for contract and prepaid.

OK I get your point BUT the phone if fully functional, I'm using a SIM from a different carrier, I have a data connection, make and receive calls, the whole nine yards, it just won't let me see what APN setting it's using and the R symbol is in the signal... once again, IT IS allowing the use of a different SIM from another carrier
Yes its the same as me! I have the R showing as well.(if you put the Claro sim in the R will disappear yes?)

Yes when I use a CLARO SIM the R disappears....
BREAKTHROUGH... I think that I have found the culprit... since I live in Costa Rica I use Market Enabler... apparently whatever it changes is causing the problem, which is weird because I have 3 other android devices, I use the same app on all of them and don't have this issue... NOW I'm really scratching my head... guess I need to contact the dev?
Ahhh. So Market Enabler is changing the CSC which is causing the network settings to disappear/barf.
Nice work finding the source of the problem Yeah tell the dev. Hopefully they can find some sort of fix/workaround so you can still use Market Enabler.

Well I just through and installed and tried ALL the market unlocking apps and they all apparently do the same thing and causing the same result, my phone thinks it's roaming, so now the head scratcher is why my other Android devices don't behave in the same way? This is my only Samsung. The others are Dell Streaks.

Sorry to bump this up, but I'm having the exact same problem. I was wondering if you ever figured out how to fix it.
I have a HTC Sensation and it happened to me right after I upgraded my custom kernel version to a newer one.
I never installed Market Enabler nor Market Access but when I check the SIM info it shows incorrect MNC and MCC values which
I can't change... they won't save in the system options.
I thought maybe my SIM card is screwed up, so I'm thinking of getting a new one from my service provider.
I just have to check it on a different phone first.

[Q] CM9 Rom displaying No service since switch to EE (formally t-mobile UK)

I have been running the CM9 rom on my Galaxy S3 fine until I recieved an SMS from Tmobile stating that my signal has been switched to EE.
However now my Carrier is displaying 'No Service'
My phone still works correctly so appears to just not reconise EE as the carrier.
Has anybody else had this? and does anybody know if there is a fix for this.
I want it to properly display when have signal not just a custom carrier name. Is there a way to update the carrier list?

I'm on Orange, using XXDLIB. I had a SIM update text, deleted and rebooted, and lost my signal too!
I left it about an hour, rang Orange, and during the 28 minutes of queing I rebooted and got another text, rebooted again and it was working, with "[email protected]@@@@@@@@@" showing as the carrier in the pulldown thingy. Not sure what the @'s are about!
So my solution... patience!

Contact your network the phone cannot know that the name has changed .
Unless you have a brand new Sim or an update as per the other post.

Sorry mate, don't use CM.. I prefer the sammy ROMs.
A wild guess - maybe the T-Mobile CSC isn't in the ROM? Don't know if that would affect actually connecting to the network though.
Might be worth posting in the CM9 thread.
Help us sort this please!?

Same problem here yet Im on CM10 Dark Paranoid Android. Does same on any other CM10 ROM that I've tried too (Slim bean, CM10 Milestone 1 etc). Doesn't affect usage, just looks unpretty because now displays "NO SERVICE". Now and again says T-Mobile, but never lasts long. Have tried the option of editing a file - I think was callled spn, and also have tried Carrier Name Changer from google market with no avail.
Any help would be much appreciated

Problem with data internet

Hey guys,
Few days ago I bought new S2 for my girlfriend, put in a sim card, then got a message from operator with internet and mms configuration, I installed it and after that I noticed that mobile data internet connects only on EDGE, but not 3g. ROM is stock.
Any suggestions how to fix it ?

No mobile network but data works

Hi all,
So my friend has a galaxy s 3 and he's not getting service so I said i'll take a look at it.
So i rooted it and changed roms and stuff and I put my sim in and add the apn settings of Giffgaff and
I got data connection H+ but then I tried to make a call and it says No mobile network phone.
I checked the imei and doesn't appear to be corrupt and I checked *#0011# and it said IMEI CERT = Pass.
So don't know what the problem is and the phone is sim unlocked .
I checked online to make sure that the phone he gave me wasn't blacklisted or anything just in case lol
Thanks!

Must be hardware failure then..If phone is not stolen/blocked different stock software doesn't work imei is intact apn settings are ok and patched modems kernels not working than all options are pointing to some sort of hardware failure.

Getting a H+ signal is different from actually getting a working data. Try to check if data is really working (browsing etc).
If there's no data even with the right APN, means the phone is probably black-listed from the carrier or you need a new (patched) modem. The right modem will solve this issue if it's not black-listed
If the data works but no phone calls, means you can try to flash stock rom and see if the problem persists.
If you were on 4.3, don't flash to 4.1.2 btw
PS: There have been a lot of refurbished/refreshed Sammy phones on the market. Their hardware issues are well known like bluetooth stops working etc etc. So if he/she got a refurb, then probably hardware issue as well.

Data sometimes works even if the phone is black-listed depending on the carrier and their implementation policies. Wifi always works though.
You mentioned changing roms.
So which rom are you currently using?
More questions:
Can you try stock 4.3 for your device/carrier?
Are you using the same telcom operator (carrier)?
Is your phone carrier-locked?

Anyone, please help.

I've tested my SIM on another phone and I didn't get any network problem. I guess this is a software or hardware problem

Well a little more information would help you get a better answer.
Are you using the stock rom, custom rom, rooted, kernals, any mods....

I'm using latest March update Android 12.1. Rooted. Installed VoLTE Module via Magisk.
This all had happened after December update. On January 8 I got updated carrier services and SIM tray area got too hot and I had to reboot and eject my my SIM. After that my Pixel 6 couldn't receive and make calls on 4G/3G, only 2G works. Tried many things: reset network settings, reset factory settings, downgrade firmware, install custom rom, nothing helped.
So, that's my weird problem

Borrow a friend's SIM and try it in your unit. If it fails to work the issue is hardware. Otherwise it's likely a conflict between an update and the Magisk module.
I do believe however yours is a hardware issue. I don't know what caused it but the end result is a burned-out modem chip.

Thank you guys for your kind and prompt response.

I had a similar problem, look for "carrier services" on the play store and join their beta program after few mins it will ask to update to the latest software do that and reboot your phone, come back here and let us know if it fixed your problem

I've been using beta Google Carrier Services since I had a network problem.
Didn't solve my problem yet unfortunately.
