Galaxy S cant find sim card

Today i went to the gym, and when i was done and picked up my phone in the locker i needed to call someone. I called but it froze during the attempt to call so i turned the phone off (i could turn it off normally, so i didnt pull out the battery). When i turned it back on i had no signal at all, and went to mobile networks settings to check. I got the message that i had to insert my sim card to edit the settings.
My phone was running JM5 rooted. I tried switching sim card to see if my sim card somehow stopped working during those 2 hours but that didnt help either. I then tried reflashing (now have JM7 on it) and i still have the problem where it wont find my sim card.
Is there anything i can do besides send it to be repaired? I'd prefer not to do that seeing as i really hate waiting for it to come back.

You have probably tried it, but I'd get a cotton bud and clean the contacts both on the phone and the sim card. I've had that happen twice, but not on my SGS.

Yea tried that already.. thx for the suggestion though.
I guess i better hand it in to the repair shop.

I also have this issue with my SIM card, i go to flight mode and return back to normal mode seems to fix the issue ive also cleaned the contacts before and it didnt seem to occur again..

First fix is always factory reset.

Yeah i have tried that, it's not working either. Tried several different Roms and different modem/radios too. This sucks.

I have the same problem. It started after I flashed JVK on my phone. I thought it was the firmwares fault, but I still have the same problem after flashing JS8. I think I'll be asking my provider for a new SIM. I have a feeling that the SIM might be the answer to our problem

Check IMEI in your phone.

I have sent the phone back, it turns out he had deleted the efs folder, thus screwing the phone, refund was issued and it's all good

Nexus 4 - No Service

Hi all,
I got a Nexus 4 from Ebay. Cellphone is in flawless condition, it probably has less than a couple of months of use. Unfortunately, I am not able to pick up a signal in any way. I just get a constant "No Service" message, and occasionally it will jump to "Emergency Calls Only".
Testing menu says Signal Strenght is 0 dBm 99 asu, no neighboring cells and location is unknown.
I've tried changing the prefered network to WCDMA only (as suggested in other threads), also tried with the other available settings with no luck. Tried playing around with the Change Bands setting as well but it makes no difference
Tried with a few different sim cards as well but that didn't work either, just got signal momentarily and but it would go on and off.
Cellphone came with 4.2.2 and I upgraded to 4.3 as requested by the system. Same issue.
Tried basebands 48 and 84.
Tried CM 10.2.
Replaced SIM card with a brand new one.
Cellphone doesn't appear to be blacklisted either.
Not sure what to do next. I'll try to get in contact with the seller but I don't expect much from him or eBay. Maybe I can sell off the device very cheap for spare parts, or send it for repair somewhere? Leave it as a dev device (which would virtually indistinguishable from a N5 that I plan to get anyway), Anyone else has any other suggestions or ideas?

Try to install a factory stock image: http://forum.xda-developers.com/showthread.php?t=2010312
If you pay with PayPal you get buyer protection so you can try to get your money back.
Could be a hardware or antenna issue.

To me it seems like its been blocked for certain reasons. Either it was reported stolen or the person who sold it to you didn't pay his/her bill for which the carrier blocked it. In that case you can't do much about it.
I would contact the seller right away. If you get no response contact paypal and eBay.

This problem is occurring for a lot of Nexus 4 users, including me. Its some sort of pandemic. Here’s what you can do to atleast restore service to your phone : flash the factory 4.3 image to your phone, again. However, try flashing a radio that is 54 or older with it. Make sure you wipe the cache and flash all the partitions, system, boot, bootloader and the old radio. This will bring back service to your phone (did for me), however you will be left with no in call audio and your phone wont connect to the internet through the mobile network, only wifi. After doing this, you will see your baseband and IMEI in the phone.
You can use this as some sort of “test” to verify if your phone really isn’t stolen. What is the ultimate resolution to this problem ? I really don’t know yet. I’ve been breaking my head over this for the past 4 days now. Maybe I’m going to try out the unbrick method mentioned over here to see if that helps.

As an update I am getting intermittent signal in some areas, but it's really spotty and only lasts a little while : (
I'll be giving different basebands a try tomorrow but I don't think it'll help much. I'll also try the full factory flash posted above.

Same problem here, had the phone for about 2-3 months, bought it off Kijiji, I tried flashing 4.2.2, went back to 4.3, flashed every baseband and still no success. The SIM works perfectly in another N4, tried a few other sim in mine and still the same results. Any other ways somebody got this fixed ?

I'm talking to the seller, see if the phone is still under warranty. My other options would be to change the antenna myself (see if it works), or resell it at loss for spare parts, or wait to see what eBay says.

Just to give you guys some hope, that this is not just a problem faced by second hand phones - My phone is bought directly from the Play store - I contacted Google service a few days back and they asked me to return the phone for a replacement. Only problem is I have to ship this back to the US (where I purchased from), since they dont provide replacement service outside the country of purchase. I'm in India now.
I've tried absolutely everything myself. Flashed many many radios, 4.3, 4.2.2, I'm only able to get it to the point where there is network coverage, I can make and receive calls but there is no in call audio, nor is there any mobile internet connectivity (Only through wifi).
Something tells me this is a problem with the latest OTA update that caused this issue - I was completely stock and everything was working properly, when this problem appeared one fine day - It started with me not able to connect to the mobile internet network for a few days, and then one fine morning, BAM. No service. It was only after this that I started flashing and re-installing stuff on my phone, desperately trying everything to get the phone back to normal again.
I think the last OTA update somehow "bricked" the radio (dont know if something like this is possible, just a noob guess). My only hope is the 4.4 update has some fix for this, else I'm going to try the unbrick method mentioned on these forums to see if that works. Only then will I take the pain to send this back to the US.

What's the unbrick method you are planning to follow?

I was considering using the unbrick method listed here : http://forum.xda-developers.com/showthread.php?t=2347060
Although I'm not completely sure it will work. Do you or anyone else have any suggestions for this ? I'm hoping 4.4 gets released ASAP, I'll download and root that as quickly as I can, hopefully Google has some resolution to this stupid problem

i have exactly the same problem
i have exactly the same problem. i bought my phone at US from Google play.
the phone worked fine for two month and then i got - No Service, and its swipe in a sec to emergency call only.
i try to replaced some sim cards, and factory reset with no success.
i also read a bug report that opened in Google : 58317
they told that there is a problem with the radio interface and radio driver at the 4.3 update, and they will fix it in 4.4 kitkat version.
i hope that 4.4 will fix this terrible problem, if not the phone is totally a door blocker..

Did anyone ever find a solution for this issue?
My friend has this problem with his Nexus 4.
I've searched A LOT and to this day (half a year later) haven't been able to find someone who reports this problem was solved.
I've also tried every suggestion I could find: flashed every stock image available, tried every combination of stock/custom ROM/recovery/radio, even tried the unbrick method mentioned above.
Nothing helps. I always get the same symptoms:
- Radios 54 and below - no in call audio.
- Radios 83 and above - Baseband unknown, IMEI / IMEI SV unknown, no cellular reception.
Also, RMA is not an option because the people at the store (a) don't know how to fix it and (b) claim the warranty doesn't cover this issue so they won't replace the device.
Any suggestions? I'm willing to try anything...

Maybe its a simple hardware failure like a loosely connected antenna? It doesn't really seem to be connected to any specific software setup
Something that happens to me rarely: when I'm in an area with very low/no reception sometimes the phone won't reconnect itself again and just stay on no reception until I reboot. Only happens like one or two times a month though.

Thanks, but I really don't think it could be an antenna issue.
I can see how a malfunctioning antenna could cause cellular reception problems, but it shouldn't affect IMEI or Baseband version readings. Those things have nothing to do with the antenna.
Also, the fact that the symptoms change with different radio firmwares says there's a big chance this is a software issue after all.
I just can't figure out what the cause is and how to eliminate it.

Flash any full factory image. If the problem persists after you can be pretty sure it's hardware. No signal for most of the time and occasionally picking it up could be something as simple as the antenna being unplugged, which can sometimes happen after a drop, or a forgetful repair.

Could be a broken or badly connected antenna. They are very fragile. Have a look at how to replace the antenna maybe?

I've opened up lots of my old phones (not my nexus 4 yet) and its normally easy to find and change as it's separate from the motherboard and looks basically like a piece of plastic!

I have the same problem no connection but the phone recognize the sim and the number of the phone. I've tryed to return to stock using a factory firmware but I'm not able to fix the problem... (this morning is working fine and my phone never fell down or something like that)
If I open btw the case and try to remove and reinsert correctly the antenna the phone will recognize the signal?

Note 3 N9005 Reception Issue

Hoping I can possibly gain some insight. The Note 3 I have had no other issues than a charging port had been broken off (wife was a little rough with it), and ended up having to replace the port itself. The port is the correct model and type for this phone, made sure of it. I factory reset the phone and I made sure to turn off the diagnostics for Samsung (since I know that can cause problems with cell phone reception). It worked for about....4 hours before it stopped finding the network. I did another factory reset and the signal came back. Am I going to have to continue to factory reset just to get service back? Or is there a workaround that I may or may not know about? The device is not rooted with the latest firmware (5.1.1 I believe), the APNs are correct, and the SIM works in other phones. I'm completely drawing a blank.

Possible loose connection inside the phone?

Possible wrong modem and CSC for your network .
But 4 hours working suggests lose connection or even faulty sim card .

I opened it up and checked the connections inside the phone itself, the wires are properly seated and tight. I'll flash a new modem with the proper CSC just to be safe.

compatibility of lcd screen
Is the lcd screen of galaxy note 3 n9005 compatible with note 3 n9006??

The only way I know how to turn it off is that you have to factory reset the phone, and when you are in the initial startup (after selecting your WiFi) The very last option a Yes or No to send Diagnostic Data to Samsung. Don't know how to do it other than that method, if someone else knows, feel free to correct me here.

thanks for quick reply. yeah i have done that.
but i have issues with LTE reception. may be some other issue.

I also have the same problem!
GSM mode works, GSM/WCDMA has some failures, LTE/GSM/WCDMA has many problems! I have 1 bar or 0 bars all the time (while other phones with the same sim card have full bars).
I don't know if it is an antenna problem or really the main board problem (since software isn't an issue because I tried stock, cm based and note 5 port roms and everything has the same problem).
I'd like to troubleshoot things a little bit so I can get this repaired myself, anyone knowledgeble here so we can get our problem solved?

Axon 7 A2017g b04 Cellular Radio off ???????

Hello,
I just got the Axon on amazon, a 2nd hand one.
I inserted my sim card and there is no way to have the cellular radio on. I did an full wipe twice, swapped sim, inserted a new one... nothing. Signal strength is zero. I tried also to do an emergency phone call (it should work even without the simcard) nothing. It says that I'm in aeroplane mode. But it's not. I did a manual search of the network, it says error while searching for networks... If I select choose automatically it says registered on the network (but it's not!).
I installed LTE discovery and it says that radio is off... I've tried to reset data connection... nothing...
any thoughts ?
I will send the phone back to the seller but if it's just a software glitch I would rather keep it ....

-Look on the back of the phone, below the Dolby Atmos and "do not dispose of" symbols, and tell me what is the model of the phone. It may be an A2017, and if that's the case maybe they installed the wrong modem and erased the IMEIs
-Try putting your SIM on the 2nd slot
-Try finding the phone's IMEI from the system, maybe it is under About phone - Signal status or sth like that.
-Try another SIM
Those are my ideas for the time being. I also remember there was a secret code that you can put on the phone app, it opens a settings app with a bunch of tweaks and you might be able to change something. Just google "axon 7 secret codes" or similar

Send it back... almost 100% not a software issue

Mine stopped working out of nowhere, the radio that is. I sent it back in and they send me a new one, no questions asked. Although the replacement they sent me may have been refurbished and I set the phone down and picked it back up and the screen was unresponsive after. It turned on but I think the digitizer got unplugged or something because I couldnt do anything on the screen. Yay for mid-range phones?

I've read that you can fix that by applying pressure on the screen, like in the center, then going to the sides or something like that...
The digitizer is the same plug as the screen though, so it didn't get disconnected

Phone start showing No service after 6 months, detail in thread

Hi,
I am using LG G6 LG-H870DS and it was working A ok till yesterday.
Last thing i remember was installing and using "GPS JoyStick", i was able to mimic US location while sitting in Asia. Later part of the day when i checked my phone, it was showing no service (although it was still showing my mobile operator but no service).
Went through internet and did all possible tricks
1- Checked IMEI (inside the phone->about) and it match to box IMEI (so i presume no problem there).
2- Did hard reset (did a backup before doing hard reset), no avail (did reset 5-6 times, thought to try a few times in case i was not doing right).
3- Saw some threads with similar problem and steps to change Mobile Network->Network Mode->GSM only. But my phone didn't respond while clicking on any other option, it just got stuck on GSM/HSPA/LTE.. auto. I even Used *#546368#*870# method and under RAT setting tried changing to GSM only but it popped the message failed.
4- Used another SIM card, didn't worked. Used my own SIM card on other phone, worked just fine. So i presume it was not my SIM card issue.
Fought with my phone till 2am end up gave up and decided to visit LG service center in morning.
This morning went down to service center and service staff used some LG dongle to reset the firmware to no avail, same issue he was not able to check/uncheck any option under Mobile networks.
Once clicked Operator it showed error. He tried his best for 40 + minutes but endup he decided to take the phone in to send for repair (which he said will take 2+ weeks, as they don't have any replacement phone available there).
After all this exercise i would like to know (if any one can answer) , if "GPS JoyStick" is culprit in screwing the phone. Is it even possible for an app to screw the phone to the extent that it can't be used even after doing hard reset? Or was it just hardware which broke down and have no direct relation to the app i installed?
Would appreciate if anyone can shed some light.
Thank you,
LEE.
