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..

Can anyone help?
Have xda atom but cannot use it on t-mobile uk! Keeps connecting then disconnecting and have no gprs signal. Have had a new sim card sent but still having the same problem :evil: The sim is a 3g sim but t-mobile says that does'nt make a difference should be able to use in a non 3g phone? Is that True??
Put my orange or vodafone sim's in and connect to their networks no probs.
Anyone any suggestions please? :wink:
Try it on other non 3G phone? or try it at different geographic location
Thanks for your suggestion hanmin. Have tried different location but still the same. tried in another non 3 g phone and had the same. Have signed up on an o2 payg chip and no probs and have also now tried an orange 3g chip and that worked too. Now in dispute with t mobile as the chip is now playing up in my mda pro too and has been for a while (not a faulty pro after all maybe!)
Wished never switched to t mobile as always been an orange user!! why oh why!! :roll:
Have the same problem as you but on Virgin MObile UK. Am thinking of changing providers. Just moved from australia and brought my o2 atom with me.
Just to confirm, you've tested with vodaphone and o2 SIM and both worked fine?
Hi tristrem21 sorry have'nt looked on xda developers for a while! so did'nt notice your question regarding service providers. Yes have tried it on o2 and Vodafone and the sims work fine. It will also work well on Orange too.
same problem, bump for solutions
anyone though of anything yet?
thanks for the tip lob. have switched to o2. works fine now. cheers
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.
I've seen similar threads but my case may help to solve the issue.
I was using my Turkish sim card without any problem for 2 years.
My latest ROM was official leaked 4.1.2 XXLSJ .
I've traveled to Norway from Turkey. After I switched from Airplane Mode to normal mode I saw that my phone can't register on any of the networks here. I tried to do it manually but it didn't work either.
Then I used my second cell phone (E72) and it was fine and it got registered.
I bought a norwegian sim card from here (MyCall-a telecom company that uses Mobile Norway infrastructure) it was working for few minutes but it lost registration as well. When it was working for first few minutes it showed that it registered to Mobile Norway not MyCall.
When I used the MyCall sim card on my other phone it showed MyCall and worked without any problem.
When I activate Mobile Data on S2 it shows an R letter on signal bars so I'm assuming it thinks it's registered with Roaming to Mobile Norway even tough the sim card is MyCall.
I went back to 4.0.4 it was same. Worked for few minutes than I saw "emergency calls only" (not registered)
I went back to 4.0.3 and S2 started working fine and it showed MyCall not Mobile Norway.
So I think it definitely has something to do with MyCall working on Mobile Norway or my turkish sim card working on other Network.
Anyone has done roaming with 4.1.2?
Do you guys have any idea why it's orking in 4.0.3 but not in 4.0.4 and 4.1.2?
Recently, I got a prepaid T-mobile sim for using in a business trip. After the trip, I put back my original T-mobile sim in. But, the Amaze does not recongize it. I tried my original sim in my wife phone, it is recongized. I have tried several working sim in the Amaze. The Amaze does not recongize any of them.
I put back the prepaid sim, it works. It only recongize that particular prepaid sim. All other sim does work in it, it just shows No SIM Emergency Calling only.
It is a very very strange problem. Any luck to solve it ？
my amaze is running custome 4.2.2 rom. sim unlocked. s-off.
It worked fine (can use different sim). before using thatparticular prepaid sim card. Now, it seems that it is locked that particular prepaid SIM.
please help!

Have you tried putting in the SIM you want to use then going into your Mobile Network Settings and searching Network Operators, then selecting the network; and/or, resetting your APN to default?
yes. but it did not work.

My understanding is that a phone does register on T-mo and associate the IMEI and SIM. If you've ever looked at your Plan on My T-mobile you see that your phone is listed. When I switched from a Wildfire S to the Amaze it did switch after a couple days and show the amaze...all on its own, and of course for that phone number...but I was not switching SIMs with different numbers or 2 different SIMs with the same number, whichever is your case. There are a lot of variables that you didn't mention, so instead of the 20 question thing I would respectfully suggest you just call T-mobile and get them to switch things. I know, I know, I like to figure this stuff out too, but sometimes you just have to have them help. Alternately, of course, you could just do a live chat with support...might have to get a support login (they are separate from My T-mobile logins).
My phone is sim unlocked. When I put in att sim , it still say no sim card. I tried different sims, it always says no sim card. It only recongizes that particular sim card

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
