Roaming connect failure - Galaxy S III Q&A, Help & Troubleshooting

Hey,
I was wondering if someone have a problem with connecting to 3g while traveling to another country. I installed last week the JB version with Kies because OTA wasn't available due to many connections.
I live in the Netherlands and using KPN as provider. I bought my phone separate so no branding or lock.
I travel nearly every day to Germany but since the update the phone doesn't connect to 3g. I have to turn off the data roaming option. I also discovered that my 3g is not as stable as before.
Someone hints what to do?

Problem to connect to 3G

hi everybody,
i have a UK T-Mobile Motorola Atrix that i received as a gift (MB860; 45.31.2.MB860.T-Mobile.en.GB; android 2.3.4). I live in Morocco where there is no T-mobile. I try to set the phone up to get 3G connection but it never works. it keeps trying to synchronize and changing the signal from normal to 3G to H and so on.
i tried my simcard in other phones and it works and I tried other simcards with 3G in my phone but still the same problem. i called my network technical service and they told me to upgrade the OS. i did it since there was an update available in the t-mobile web to the version mentioned earlier yet the problem persists.
when i see other phones with android there is a option to activate the 3g that i don't have in mine, i think because it's a t-mobile version.
can anyone here give me a hand with this?
thanks in advance.

Network just lost

Hey guys I was just using the miui rom and I rebooted and the couldn't pick up any reception so I pulled out the sim and reinserted and then rebooted a few times. My contract is still up for 10 months and I'm constantly getting emergency calls only. I tried a wipe and then changing to cm9 but nothing. Should I call my operator or stock rom?

O2 is down in the UK mate for a few specific people.
I'm on Giffgaff (runs on O2 network) and I've had no signal since about 1pm. As said it's a network issue. Just wait, it'll get sorted.

Samsung S3 on Three

Hello,
Anyone one got one from three.co.uk? I'm finding the software is clunky out of the box. Is that because the three ROM is rubbish?
Thanks
What part do you find clunky?

When answering a call the screen transition lags, the animation when closing and opening apps stutters.
Have you tried upgrading the firmware?
The newer ones are significantly smoother than the original stock.
If you want more "smoothness" then I'd recommend a custom aftermarket rom such as Wanamlite or Omega

When I connected it to the wireless internet for the first time it said there was a software update. But when I clicked on the update it said there wasn't one? Where do I get the update from? I've currently got 4.0.4 (API 15)

Hi,
I'm also on Three UK. Currently using Omega 9.1 (Firmware:XXBLG1, Modem:XXLFB, CSC:H3GALE4).
It functioned better than the original stock but I bought the phone 2 days after it was released in the UK so I never tried any of the stock firmware upgrades via Kies. I'd be interested to hear how you get on of you go this way. What version on you on?
Aside from using it as a phone I primarilly bought it to act as my home broadband provider on the "All-you-can-eat" data package as my landline internet connection is appalling (I live in rural Cornwall!).
So I'd also be interested if you ever experiment with different ROM/MODEMS & CSCs and what works best for you. Three in the UK are unique in that the transmit using UMTS protocol on 2100MHz frequency so I wonder if the Three specific modem which for me was originally NELE4 works better - I am thinking of re-flashing that modem but at the moment I am offshore so there's little point.

[Q] Problem with signal...

My Galaxy Ace i (gt-s5839i) is having an issue, It cannot register SIM with it's mother network.
It was working perfectly fine, three or four days ago, when we're abroad. We were using Polish SIM. Now, when I am using a SIM with roaming (Polish one) it goes well, but when I insert a local SIM (UK, giffgaff [runs on O2], or plain O2), it doesn't.
You can actually see the signal bars, you can search for network providers, but you can not connect to any of them.
Simcards are working in other handset, so they're fine.
I've tried to reflash roms, both with clockworkmod and odin.
Both branded and unbranded.
I've SIM unlocked it again...
Has anybody any clues?
Thanks in advance.
Problem may be with the firmware..
Firmware may be of different country..

S2: No calls, but mobile internet works

Hello,
I'm trying to help a friend of mine from Italy. She has a S2 which had the strange problem that phoning was not possible.
First thing I did was resetting the phone which didn't help. Then I flashed paranoid android and at first it worked with Italian Sim Cards.
The phone was left untouched for a few weeks. When I used it, the old problem was back. Then I tried flashing CM, didn't work. Then the Samsung Stock Rom for Italy, then for Germany, then a branded one (the original), downgraded version also. Still, it didn't work. Just the mobile internet worked. IMEI is not corrupted.
The really strange thing is that every time it worked with my German Sim Card - over Roaming. I could call someone and receive calls.
Technically speaking, there is just one modem for both roaming and national calls, right? But how is it possible that it doesn't work for national calls? I tried several providers, but nothing.
When you say 'mobile internet works', do you mean 3g or wi fi?
If you mean wi fi and not 3g....is it possible that the phone has been blacklisted or the sim blocked?
Have you tried searching for and selecting the correct carrier in the phones settings?

No, I mean 3G. I don't think it's possible, she bought it regularly in a shop and had suddenly this problem. But what could be a reason for banning it?
Yes, I tried to connect manually. Different carries are found, but it cannot connect to any carrier, it says try later!
Check the battery.
Try some other battery you will be shocked to know that its caused due to battery loosing current and this especially happens on low charge levels
