Hi
I replaced my P3300's screen a while ago because it was cracked. Everything seemed to go OK and the phone worked fine for a few days.
I don't know if this is related or not (maybe I messed the antenna up during the process, but since it worked for a while afterward I'd guess not...?)
Anyway, for the last couple of days I've had no network reception whatsoever.
The last time I remember it working was in the evening a few days ago. I fell asleep with the WIFI on and woke up with the phone dead. I turned it on and it didn't ask me for my PIN like it usually does, and it couldn't find my GSM network. It's been like that since.
When I press the green "dial" button nothing happens. When I go into settings > telephone, it asks me for my PIN and I can then access the options but it doesn't find any networks when I search.
Now every time I turn it off and back on, it never asks for my PIN.
I've tried removing the battery and the sim card but that hasn't helped.
Any ideas??
Thanks in advance
Meh. On a possibly maybe related note, I've just realised my PocketCM Contacts hangs when I try to launch it. Could it be a loose sim card connection causing both these problems? Although I'm pretty sure all my contacts are on the phone and not the sim card, and the sim looks fine and is placed properly...
edit - just been into programmes > sim manager (not sure that's what it is in english, my phone is french) and I get a "sim busy" error message (again, not sure if that's exactly what it is in english...). Hmmmmm
Well it gets even weirder... It seems I can receive and send text messages!
I've been getting texts from my operator saying I have new voice messages (which I obviously can't listen to) and I've also had texts from a friend and been able to reply to them and they've been received. Even though the icon at the top still has an exclamation mark so supposedly no network.
My iGo GPS also doesn't seem to work anymore (it hangs during initialisation process) although Tomtom works fine.
Someone please tell me they have an idea what could be going on! This is doing my head in
Dam, you have all my solidarity man!
Are you using radio 3.39.90 by chance? Even if not I would still flash another radio.I also suggest to check that your device was correctly reassembled if you have any doubt about it.
Hello all,
my Defy is stuck in emergency mode and can't find my carrier anymore (o2). Details:
- only emergency calls possible, no network found
- another mobile in my house gets outstanding connection (o2 aswell), when switching SIMs, it's still my Defy not getting a connection
- wiping the Defy has not changed anything, even with stock settings all I see is the red cross (put my settings back with clockwork recovery)
- an hour or two before this happened I was listening to music with my headphones, but between taking the headphones out and GSM failing I was sending texts
- When doing a search for other carriers I can see some (though not reliably), but not mine
- I bought my Defy via Amazon, so no SIMlock, obviously.
- WiFi, Bluetooth and GPS are all working fine, so they probably have different antennae
- I rooted my Defy, but this was over a month ago, and it was working fine. I also did not install apps or update some existing ones before this happened. I also did not reboot. It just happened. Put it in my pocket and next time I got it out there was the red cross.
In Phone Info -> Status it says under signal strength "-111 dBm 1APU". It all looks like the antenna is broken, but I didn't hit it, drop it, put it into water or hurt it in any way before this happened or the 3-4 days before. So I'm really lost here.
Anyone? Thanks in advance.
Hi. Have the defy for about a month now. Same issue since first day. Dont know whats wrong. Found out that after 4-5 reboots its ok and lasts till next reboot/switch off. So try turn it on/off 4-5 time or just download a quick reboot app and do the same to see what happens. If aneyone has any idea on how to fix this?
i get this all the time when i flash my defy thru any other rom......and thus roll back every time to stock (indian) rom.....
try flashing your phone with any compatible rom....new radios might get ure phone working
Same problem here. First time today, spontaneous, after a month of use my Defy, non rooted, never unlocked, standard noMOTOBLUR, just like as it was bought from store. Moto_Versiuo.2.34.1.MB525.Retail.en.SEA
None of these worked to restablish the radio connection: succesive reboot, manual/automatic network search and choose, succesive airplane on/off. I didn't check the signal parameters.
I thought that the SIM just burned, removed and try it on another phone and everything was OK. When put it back in Defy, the network connection was established.
The experience was very strange and my final verdict was that the SIM just moved a little from its initial position.
BUT now I realize the problem is more complex and I don't know what caused it !
I have also noticed that the sim card slot gives a little more space for the simcard to move (at least on my defy). Might be a prob with the sim card being old or something (mine is from 2005). For now i'll just try to keep my phone on (seems i finally found stable settings for setvsel, so no more unexpected reboots).
An answer from motorola's official support forum is just remove the simcard and clean it with some cloth...
This is definitely a sim slot/card problem. If bought from amazon they will oblige to change it without any money. I did the same but not for this problem.
If you think there is some problem with software, which is unlikely then flash an sbf and see if things are fine.
To begin with flash chinese froyo sbf. It is downgradable to any previous firmware you were using and very flexible.
Hope this can solve your problem. Get back on what the result is.
Same here...
My defy got network yesterday at 07pm til mid-night.
before, since 16 (11pm) til 19 (7pm) before it function again.
and now, its bloked.
i rooted my cell one month ago, then, probably thats not the fault of z4root.
Sorry about my badass english, i still in upgrade mode.
any idea about it guys ?
thnx

Problem solved replacing sim card with a new.
I have a T-mobile G3 (obviously) that I've had for about a year and recently it has been saying that the sim is either invalid or not installed. This is the same sim card I have been using for a while. Occasionally after several restarts and removals/re-inserts I can get it to work for a bit but then it will to back to invalid sim. Does anyone have any suggestions of what the problem might be or how to fix it? I get both the invalid sim and sim not installed messages.
Is a SIM card from a different carrier installed? Have you tried a new SIM, performed a factory reset, or possibly shimmed the card so it fits tighter in the slot?
Nope. T-mobile sim card and a T-mobile phone...all my previous phones I have rooted or at least unlocked or something. I have done absolutely nothing to modify this one from stock.

did you figured out the problem? It just started happening to me.. super annoying...
Nothing that I tried worked. Ended up deciding it was a hardware issue that wasn't worth trying to fix.... I was thinking of replacing the Sim tray but that's close to impossible on that phone. Ended up just trading it in for a G4

Old topic but the same thing started happening to me this week. At first, it wouldn't happen till I would reboot the phone and it was pop up with the no SIM card symbol and subsequent reboots wouldn't clear it.
EDIT: Tmo D851 with same Tmo SIM card since purchase, on Tmo network this whole time.
Surprisingly, flashing an old backup img would fix the issue for a day or two and upon another reboot, it would be back.
Now this morning, phone was sluggish and locking up, rebooted it and the dreaded symbol was back and no matter which backup img I used, it wouldn't clear. I had thought it was one of the app permissions I had blocked (though none were system apps) and reset all permissions, cleared all caches, thinking it was a software issue. Still wouldn't clear.
I even went so far as to do a complete factory restore via the LG flash tool, right back to out-of-the-box-new, and STILL the no SIM card error was there. Tried rooting and flashing another backup, still there. Add in numerous rinse and repeats of various steps and still there.
Went to T-Mobile and they swapped for a new SIM card and it was still popping up. They did the normal, factory restore from the settings menu, still there.
I was starting to think Tmo was blocking my account due to my data usage (paranoid, I know...) and asked if my account was being blocked or my number and was told nothing listed or said.
Of course, the 1-yr warranty on this phone just ended in September and I'm high and dry with getting this fixed.
Also of note, none of the pins are broken, misshaped, flat or other. I even tried placing a business card piece on top of the SIM card to try and see if it wasn't making contact, still no joy.
The SIM card does work in one of my old Tmo phones, so it's not the account.
Just sucks that this phone is now crippled from such a silly mechanism as such, first time with an error/problem like this with SIM card phones. And I kept this phone in pristine condition, no drops, water, glass protector, etc. And it has never been dropped or other, just started up as such... My wife has the same exact phone and no problems with her's. Yet.
schneiderm3709, did you trade it in at a Tmo store? They took it with the SIM card error or you didn't mention it? Did they take it with the SIM card error at a reduced value? If either, what did you get for it?
Thanks.
Yeah, I determined that it wasn't the sim card either. I'd have no problem putting my sim in another phone, and another sim in my phone would have the same issues.. All the flashing and everything did nothing for me. I also tried a piece of paper on top of the sim card when I slid it in to help it make better contact. This worked for a little while but eventually didn't do anything. My hypothesis is that one of the pins was going bad/had a crack, and when the sim card was installed it would lose contact, and when you took it out it would pop back up to where it's supposed to be, so you couldn't see the problem without microscopic inspection.
I told T-mobile exactly what was happening with mine, and they tried all the same things they tried with you, also still to no avail. Their requirements for trade in are very simple actually, 1: NO Water Damage, 2: NO Screen Damage (General wear scratches are okay), and 3: The device turns on. Mine did all of this, just wouldn't connect to the network. They gave me $100 credit towards the new G4. I Love it and don't know if I'd ever be able to leave LG world....Unless maybe the droid turbo somehow comes over to T-Mobile. I don't know if that trade in value has changed now since the LG V10 came out or not. Hope this helps. Let me know if you have any other questions.

I have the same problem too! Really frustrating, I've tried everything and I cannot pinpoint the problem.
I found the following solution by stevenpurwadipura on Reddit
Guys, i found a fix for this. I just figured out this trick, so i don't know if this is a real fix or just a luck. Go to settings - apps - choose option - configure apps - modify system settings - choose option - show system - select NETWORK - change it into 'No'. Then restart your phone.
I restart my phone and it detects my SIM again. But as I said, I'm not too sure if this is really a fix or just a luck.

Invalid Sim Card error in LG G3 tmobile
Hi.. I'm getting the invalid sim card error after restarting my Lg g3. The sim card works fine on my husbands phone.. so guess its same issue as yours. Did you have a valid warranty when you got the 100$ credit from Tmobile for Lg G4?

Invalid Sim
I too have the same problem for sim 2 in my LG G3 D858HK. Factory data resetting did not solved the problem. I do not know what is the reason, But now i could solve it by resetting network settings. Software version - Android 6, D858HK 30b, In back up and restore there is an option to reset network settings. Done this for sim 1 and sim 2. Problem solved.
i am having this invalid sim problem after upgrade to 30e;
I found a fix for this. i don't know if this is a real fix but just flipping from yes to no and vice versa followed by reboot seems to work consistently.
i copied it. credit should go to the original poster
Go to settings - apps - choose option - configure apps - modify system settings - choose option - show system - select NETWORK - change it into 'No' or vice versa (from no to yes). Then restart your phone.

Hey, you have a link to V10c? Going to try to flash before giving up. Thanks
I found the solution go to settings > Network > More > Mobile Network > System Select > Network Mode > Global
It worked!!!
I experienced the same problem and tried most of what was suggested. Finally the following steps posted by Ayebale fixed the problem .

Same thing happening to me. I took it to a t-mobile store and they said the network upgraded and some phones are now obsolete because of it. Also, because they don't have contracts anymore, I cant get any deals on a new phone even though they didn't warn me that my phone would stop working.
Hello everyone,
First of all thanks to all who had solutions. All worked temporarily. I have a stock TMO D851 30G with the stock MM 6.0 TMO ROM. It has worked awesome for the past three years I have had it. I have it unlocked via IMEI and no root....yet. I started having this issue about a 4 months ago. I sent the phone to LG and the "techs" there checked the phone and found no issues. Still having the same issue. However, I found that if I restart in safe mode it acknowledges the SIM and works fine. Use it in safe for about 30 minutes and restart. I get my network back. I am stuck. I figure there is something in the firmware or ROM that is causing a conflict. Any ideas???? I am completely fed up and out of ideas
Sent from my LGE LG-D851 using XDA Labs
Update to this problem. It is actually a hardware issue. However it does not have to do with the sim Tray at all. It is due to a bad connection on the processor. Took mine to a repair shop here in my town in mexico. He did a reball on it (flux and reheat of the processor) this was two weeks ago and it has completely fixed the issue. Hope this helps the group out. Thanking all of you that threw in your two cents. It was all helpful
Hello!
I have problem with SIM card in my d855.
I'm on Cleanrom from September, but a week ago SIM just disconnected.
No tweaks, clean install.
I reinstalled whole phone to stock (Stock ROM locked my phone using killswitch, so I reinstalled it using BoardDiag)
Flashed CleanRom again, SIM works for few minutes then disc.
Also tried cm11,13 and few modems.
On cm11 SIM working whole night and at morning after some use disconnected.
SIM works normally in another phone.
I record log, which happens every time i turn airplane mode off, reboot or similar "SIM connect try"
Maybe my SIM reader just stopping work, but why after x minutes?
Uploading logs from phone failing, here is G Drive link:
log1
log2
Sorry for my bad English, I'm still learning.
Hi,
Lot of people are having this issue in the last couple of months.
It's not the SIM reader, it appears to be something related to heat in the transmitters area.
Check this thread: http://forum.xda-developers.com/sprint-lg-g3/help/sim-card-error-t3488208
Hi, I've problems with my device I bought online. Mainly the cellular signal keeps dropping to 0 rendering the service to be unusable. I wanted to make a thread to know if we could fix this ourselves because I didn't want to send this back to the store.
Here's the list of failures I've tried:
1. Tried to insert my sim to either slots
2. Inserted another sim card
3. Inserted both sim card and tried to swap it's slots
4. Deactivated Volte
5. Tinkered with cellular data APNs. (Mainly copied the settings from my other phone)
5. Restored factory settings
6. Repeated these steps after restoring factory settings
Also, Whenever I'm browsing media and whatnot, the back button seems to trigger itself. (once or twice every 20 minutes while watching a video).
Miui 9.0.2.0 (Philippines, Globe sim card [Other networks have the same problem])
I haven't unlocked bootloader, rooted or installed custom roms because I didn't want to void warranty and waste my time and money.
I'm hoping we could fix these problems ourselves. Any thoughts of what I should do? Should I just return this?
my "no signal" story: after 3 weeks my new mi6 got no signal anymore. i read many topics on xda, and thought it might be a software issue. although i decided to head to my mobile provider and asked for help. i got a new nfc simcard which solved the problem till now. it seems there are some issues with old european simcards on new chinese mobiles. the simcard just crashes and you loose signal.

Thanks for the reply, I'm gonna have to try and change my sim. The back button is probably a defect. It's getting worse.
