[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.

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.

Wont read sim card, no network

Help!!!
So I had the power button failure and no electronic cleaner would fix it. I bought a broken captivate off ebay and replaced the motherboard. I had to take the daughter board off my old motherboard and place it on the new motherboard cause the old daughter board had a bend sd card holder. Turned on the phone and it had a lock on it so I did a hard reset. Now the phone turns on and seems to work great except for the fact that I have no network connection and my contacts from my sim card dont show up under my contacts. Sim card worked fine before the switch and works in my blackberry right now so I dont think its the sim card. I have re-checked all the connections and they are fine. Hopefully someone can help me with this.
Thanks!
Edit: Wifi works but still no network.

I was flashing modems on the move and got a sim lock msg on boot. Had no connection to the network. I don't know if this is the same problem but I resolved it by downloading "Galaxy S Unlock" app from the market. It's the purple computer tower/wrench icon. Hope this helps!

have no IMEI number, phone not rooted.
I put the other motherboard back in my phone until I "hopefully" figure this out. Is there a way I can copy my IMEI number from the original motherboard to the new one so it will work?

/efs folder on root has my imei backup. There might be a more specific app to deal with this. A search of the forums " EW] IMEI generator and ROM zip update" might be what you a step in the right direction. Like I mentioned I just used galaxy s unlock and it fixed everything.
(Can't post links being a noob sorry)

Guess I will have to root the phone and try this method then. Thanks

I have the same problems. The power button stopped working, then before I could get to repairing it, my wife left the phone in the sprinklers and the nothing would work. I disassembled the phone, cleaned with CRC cleaner- got it working, but with green tint to everything. Disassembled, cleaned all contacts with CRC & q-tips- got display back to normal but now it does not recognize the sim card. Card works fine on old phone though. When I get home I will check the imei #.

lol, Im in Bakersfield too. Maybe its something in the air?

I tried to root it last night with super one click but the program kept locking up and stopped responding. What are other alternatives to rooting the phone?

Mine is also missing the imei number when I look for it under phone info. What does the sim card have to do with the imei #?

Go via Warranty.

Well same happened to me at first I though was the sim reader but it was the rom that suddenly stop reading the sim and I don't know why. The solution was to flash a different rom and now I am with kitslim. To check the sim reader I used the app "sim card by gsmdev" such app allows to read the sim information like contacts imei etc so if that app reads that info means that the sim reader is OK and you need to flash a different rom or the same. Hope this help

Check if your imei is intact, perhaps you could flash an FTF file which will replace the OS so back everything up first.
Make sure you are inserting the sim correctly (i know you probably are but it's worth checking) ones the sims in the phone it should reboot, could be that the contacts which hold the sim aren't raised enough, don't bother fixing them just take it back if that's the case, if the sim has been inserted incorrectly then theres a chance that the contacts may be bent and if that's the case then your warranty will be void, but in all fairness it sounds like a dodgy phone rather than any of the above.
I'd still do the FTF flash anyway, it's probably the best shot you've got, oh and i've noticed that some peoples phones will read sims and others won't so the fact that it works in yours and not hers although weird, isn't conclusive. Try another sim too.

[Q] Xperia Z GSM problem

Hello!
So I got a Sony Xperia Z in pieces, and after assmebling it the phone turns on, everything is working except for GSM module. The phone sees the SIM card, but it can't see any network. I can't even make emergency calls, and if I try to search mobile operators manually, it just blinks a popup, and says it found nothing.
Here's a screenshot from phone status screen: http://kazshu.dyndns.org/Screenshot_2014-11-24-22-04-37.png
I tried to find a solution on google, but I haven't found anything. :/ I have replaced the micro usb port since it was broken, but I didn't change anything else. Could be the GSM chip broken too?
Thanks for any help, and sorry for my english.

You probably didn't connect antenna cable on the right way. Check the cable.

[Q] No network issue LG Optimus 4x HD

Hi guys,
I have a LG Optimus 4x HD with stock rom (Jelly bean). About three weeks ago, I suddenly lost my network connection and it looked like my phone didn't recognize my SIM card. I put my battery and my Sim out and in my phone, but that didn't help. I tried many SIM cards and they work excellent on my other phone. When I turn my device on It just boots up and doesn't ask for my pin code at all. I see no difference when my SIM card is in or out my device. However, it does recognize my SD card, so I think there is a problem with the software? On the lock screen I just see the message ''no service'' and at the top I see this (first pic). When I try to dial someone it says ''reorganization of internal processes. Try it later.''. I read on a forum that I had to go to ''mobile networks'' in settings, but that isn't possible (pic 2).I also tried to put some paper between my sim card and my sim card slot but that didn't work either. Does someone have this problem too or is there somebody who can help me to solve this problem? Your help would be greatly appreciated.

I discovered that my phone doesn't have an IMEI and IMEI SV code anymore. It also doesn't have an baseband version. Do you guys know this caused the lost of my network connection and does anyone know how I can recover my IMEI number? Finally I managed to enter the mobile networks in settings by do a long tap on the data icon in the notification center. I hope someone can help me.

I have the same problem as you. With every restart the phone is unable to read the sim card. Also the baseband is shown as unknown, and I don't have imei no. The solution for me is to remove the battery, and put the phone in the refrigerator for 10 minutes.(yes in the refrigerator The phone is getting very hot when is searching for network and to have it really cool helps apparently. Try it yourself to see if it does the job for you and let us know.

Thanks for your reply! This morning, my phone finally asked for the first time for the sim password and I finally got a signal. I got my IMEI and my baseband number back. Unfortunately, after an hour or so I tried to send a sms and I wasn't able to send it. I got the error no USIM or so. The IMEI and Baseband number disappeared agian. I turned flightmode on and of and I didn't get a signal again... New today was that I am now unable to connect to multiple wifi networks too. Now my WI-FI MAC-adress is 00:00:00:00:00:00. I already lost the phone and I now also lost the smart part of my smartphone... I also tried to put my phone in the refrigerator but sadly it didn't help. I think I have to buy a new phone....

Sorry to say that "It's time to say goodbye"
I got same problem with you and try all kind of possibility. Here is final verdicts:
- Some phone repairers I know said It's the encrypted baseband partition is damaged, unless you have backup of that, it's a no-go
- I've tried to reflash the phone and it will stuck at 10%, you have to push really hard at some point at the back to make is flashable. After that, the signal back on with baseband and IMEI.... but only for a few restarts it will be gone

Hi blbterminator,
I already said goodbye to my p880 (has been replaced for the G3), but thanks for your reply. Now it's clear for me that's it's a hardware issue.
Maybe do you know if this problem only affects the lg p880 or other brands or models too?
Many thanks!
