Samsung GT-P3100 only works with radio 1800MHS - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hi all,
I have Samsung tab GT-P3100 7 inches.
It works great with 1800mhz supported sim card. When I put 900mhz sim card in it. It shows "No sim card"
I have been faced this problem P1000 tab too.
Kindly someone guide that either it is hardware issue or some functions of radio not working.

Please guide and need your help

I rooted may be try a different rom as cm10 from www.teamhacksung.org
Try to play with connection setting in setting and try to be like your other (solved tab)
See manual if it supports 900 range
Tray to switch airplane mode off then off then wait
Try to switch between 3g and 2g networks from setting then reboot
Try to enable mobile data from setting and reboot

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
I'm having the very same problem, phone model htc inspire, sim card works ok in diferents phones.
Please somebody with a solution or advice??
Thanks
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
i need help...

have you tried using other sims? maybe its not compatible with your specific sim.
maybe you just dont have any coverage, when i get the "not registred on network" message, it usualy means i'm underground, or in a place with low cell coverage, like in the woods or mountains.

The phone is factory unlocked so no issues related to not compatible and I tried with another sim too. Still the same problem. The problem only came when I flashed the 4.3 Indian stock rom. But that rom doesn't have any problem coz I've used on other note 2 too. Something related with the phone.
Hi there if you go into settings and then about device and then status you will be able to see if you have a service state if you don't have any but the network operator appears as well as signal stats. You most likely have a black listed iemi or something happened to the iemi when flashing the rom or more simple is the sim slot is broken. Hopefully you will be able to fix it sorry I can't give you that much help on this subject.

[Completed] Note 4's custom rom wont detect sim card

Note 4 is N9108w(qualcomm) . Im using the visionx custom rom. Everything worked perfectly up until I tried to manually put my apn. My phone keeps saying to insert a sim card to access mobile services. Im wondering if theres a fix for this problem?
the rom works on both T mobile and canadian note 4's so it should work in theory.

Hi and thank you for using XDA Assist
I suggest you to ask over here about your problem or you could try to ask on the thread from where you took the ROM .
Good luck!
