No Service" Error in Galaxy Ace S5830

Hi,
My issue is:
I purchased a brand new Samsung Galaxy Ace S5830 on 14-Apr-2011.
I am facing the issue related to the connection to my phone network. After I switch on the phone, I get my mobile network signal for about 30 minutes and after that the "No Service" icon is enabled and there is no signal at all in my phone.
I checked the SIM card on a difference phone and there is abosolutely no issue in getting the network signal.
I tried a different service provider SIM on Samsung Galaxy Ace S5830 and I find there is no issue either.
The problem seems to occur only with my SIM card on this phone. I changed to a new SIM and apparently that also did not solve the issue.
I am also unable to find the "Network Mode" option under the network settings, which I would normally find in other phones.
I tried with the option "Use only 2G network" but that also did not help. I am not using any 3G service at the moment.
I am now stuck in this situation and not able to use my new phone.
I am from Chennai, India and use Vodafine India post paid service.
Hence seeking your kind advice to help me resolve this issue at the earlier.
Thanks and Regards,
Venakatraman R.

Same issue
Hi guys,
I am facing the very same issue.
I contacted my dealer and got the phone replaced.
They supposedly diagnozed some problem and issues a doa on the device
Now, even in my new phone i am facing the same issue
I am using vodafone postpaid and it works fine on any other phone
Also, ive tried my dad's airtel prepaid sim on this phone and it worked perfectly fine for over 2 days
I have tried searching for this issue on any thread for sometime and finally found this
Any luck with any of you guys?

Hi ,
I too have the same problem.
The Network often gets disabled.
i have to either switch off and on it (or go into flight mode and come back) for it to get enabled.
My Sim Card is fine since when i use it in a nokia phone i never get this problem.
Whats worrying me is that this looks more like a hardware problem ... i recently updated my firmware through kies from froyo (2.2) to gingerbread (2.3.4) ... still the problem is persisting.
Many guys are suggesting to contact my dealer .. but i purchased this phone through letsbuy.com. So that option might be a hassle.
So guys any info on this issue ...?

Hi Folks, same problem here in Brazil with S5830B, no service all the time! any ideas????????????????????

U can try to change the modem of the firmware with Odin Multidownloader... try to put an unbranded rom... that works for me in my ACE.
I hope your trouble is silved with this option.... check in the forum of the developement of galaxy Ace a forum for flashing the galaxy ace...

The problem is you guys didn't post in the device-specific forum .
Try flashing a different modem through ODIN
Forever living in my Galaxy Ace using XDA App

My issue is resolved once I updraded firmware of my phone thru Kies tp 2.3 from 2.2
also you can try following:
dial *#2263#
select GSM mode and then select 900/1800 (or may be if that does not work..select other bands. my was fixed when I selected 900/1800 after I got few emergency call only issue)

It's helpful for me

Just got a Galaxy s 4g..... Us Cellular.......

I been on the search on how to root my Galaxy s 4g from Us Cellular called the Aviator... (Brand New... Only been out for a week.)
The thing is that USCC is CDMA but their 4g network must be GSM. I don't know if this is a hybrid of CDMA and GSM together or what. (<------ Don't know if that is relevant but tossed it in.) Cant find much on the phone yet....
Anyway my question is the steps to root and flash the same as the T-Mobile sgs4g?
I have tried several different ways and all have been unsuccessful and nothing seemed to work. All that I tried were Software based rooting programs. Super One Click was the most recent and failed.

You need to check the model number under the battery and tell us what it says before we can give you proper advice.

Its the SCH-R930.....

We can't help you in this forum. This is for the SGH-T959V.

For future reference, it appears the name of the phone is Galaxy S Aviator (Samsung Stealth). Your phone is VERY new. Give it some time and you will likely find develpment for it before long.

Problem with Galaxy S4-I9505 not accessing Network

Hi there,
First of all my galaxy S4 international version suddenly stopped reading or accessing the cellular network after updating from 4.2.2 to 4.3.
Note that: I bought my mobile from Kuwait and i am currently relocated to Egypt.
I heard about the Regional locking samsung did but i don't know if this is the issue or what?
So if you could help me to revert/downgrade back to 4.2.2 to get rid of this new feature samsung added to the new 4.3?!
btw I am currently on cyanogenmod 10.2
please any help would be appreciated.
Thank you,
Mohamed

The ragional locking should be mentioned on device's original box.
Are you unable to make/receive calls, or getting 'network unavailable' message?
If true- try to flash stock rom available for your country in sammobile etc.
If not- try to reconfigure your APN settings depending on your carrier,
Or try to find appropriate flashable modem in I9505 thread

Why did you create 2 threads for the same issue?
Anyways, what data network mode did you select? It should be LTE/WCDMA/GSM Auto connect.

Maybe you can flash your old radio from previous rom where LTE works? Did you try flashing roms before it happened?

6.0.1 Verizon S6 on T-Mobile?

Hey guys, so I recently found myself the owner of a Verizon S6 that my dad found on the bus when he was out near Delaware. I thought it would be an awesome addition and that I'd be able to use it on T-Mobile, I've done it before, why not on the S6? Well, for some reason unlike the Verizon S3 and S5 I've used with my T-Mobile Sim, the S6 has been very stubborn. I've tried researching online but have found mixed answers. From what I've read since the posts were kind've old, the S6 could easily be switched to T-Mobile when it was on Lollipop with a simple tweak of the APN settings. Since the marshmallow update was pretty recent, I've tried time and time again with all of T-Mobile's APN's and I simply cannot get it to work. Does anyone have any insight on this? Is it simply because its on 6.0.1?
Some info on what happens:
When I insert the SIM and power on, it simply says "This is not a Verizon Sim" with no service whatsoever and "Emergency Calls Only"
Any changing of the APN has no effect, switching between LTE/CDMA, LTE/GSM/UTMS, and GLOBAL does nothing.
Any help would be greatly appreciated, thank you in advance!

I have personally been using the same config. I don't know if it will work but I was able to downgrade to BOG7 from 6.0.1

Are you rooted? If not how am I able to downgrade? Is it the usual ODIN method?

On MM no Root, I just put the Sim card in and added APN. Maybe the phone is blocked reported lost?
