[Q] No Service - Insert Sim Card to access network services

Hi Everybody.
Well, i bought my Samsung Galaxy 6 months ago and it's a awesome phone, but now I've got some issues.
4 Months ago - My phone comes with froyo 2.2.1 so I decided to update it using kies to Gingerbread 2.3.3, after that, My phone starts to had some issues, first when I press the home button the phone didn't response, the screen was in black but I could get calls, messages and lisening to music, this was solved after reboot the phone but in any time could happen again.
Now - because the issue before, I decided to use Darky's rom 10.1 and the issue suddenly dissapear.
After 1 moth and a half I decided to flash Gingerbread 2.3.4 stock rom and a new issue appears and since there, I can't solve it.
Sometimes, my phone get lost its signal and when to "Network Selection" a message comes out "Insert Sim Card to access network services", I can't do any call o use 3g, the only way to solve it temporarily is rebooting the phone.
I use many versions (JVP, JVQ, JVR, even MIUI) but the issue still happen.
Please, I'd aprecciate if you can give some help to solve my problem.
Regards.

Hello.
Yes, right now my phone has another sim card and everything is fine, but this SIM hasn't got any plan with internet, maybe the problem is when the phone use 3G.
Regards.

May be your sim has problem not ur phone.

That's what I thought, but I changed my sim card when the problem began.
Should I change my sim card again?
Regards.

I think he meant changing a new sim card with the phone company?

Yes you should replace that sim card from your company.

ok, I'm going to chanche my NEW SIM CARD (becase it's new) for another one.
I hope this will solve my problem, I'll let you know if everything is ok or not.
Thanks.

I have just solved a similar problem with my Samsung Galaxy S I9003.
The reason was software unrelated but seemed to be a hardware connection problem. The phone was unable to access the mobile network showing a "No Service" status, also the IMEI number was unknown on the phone settings. The mobile wasn't even requesting the SIM Card code when it was turned on. But the rest of the services were working properly (wifi, bluetooth, etc).
Although i tried everything such as re-flashing, re-rooting and even IMEI restoration techniques such as in youtube "Samsung Galaxy S (IMEI Restoration Techniques)", I was unable to fix it.
The solution was to open the phone and just adjust the sim card slot connectors. I will keep the phone on testing to see if that happens again.

check IF you have your IMEI number or read this , IF IMEI is correct, check your Network settings
you can get a rescue kit from My Android Collections and or a solution from My Android Solutions
But First powerdown, pull out Battery, SIM CARD, and EXT.SD card, press power button for a minute, than powerup without SIM and Ext.SD Card...make sure you have more than 50% battery charge before you attempt any sort of flashing.

Tried them all
Imei iw correct etc

Since it is being dropped and lost Network after that
This may occur because it’s connection to the Phone’s PCBA Motherboard is damaged or bad
you may need to dismantle and check all the contacts inside to solve the problem

Hi all.
One of my friend has this device and it works perfect when there is no simcard in the phone.
But when he insert the simcard it reboots automatically after a few seconds. The simcard is MCI (Iranian operator). How can we fix it?
He tried factory data reset and updated to WP 8.1

did you (or friend) try other SIM card?
try other SIM card or ask operator to replace SIM card
also check connectors in SIM tray not bend or broken

That's quite a common problem with Lollipop, hadn't come across it with MIUI (since my phone was less than a day with MIUI).
On Lollipop it manifested itself in several ways before a fix was devised (most ROMs are now OK), maybe this can help you both:
Greyed out signal bars/no network/emergency calls only/no data: go into Settings/Mobile Networks/Network Operators, and choose a network operator automatically.
No SIM (an icon of a SIM card where the signal bars should be): go into flight mode, reboot, then exit flight mode.
