i seem to have this problem whereby when my phone starts up with a sim card inserted, the phone will boot into lockscreen for 1s then it'll start to dim into darkness and automatically reboot
this behaviour doesn't happen when the sim card is taken out
i've tried to reflash the firmware but the problem still persists, i have no idea whats wrong and this phone just came back to me yesterday from SE repair center where they changed the motherboard!
any idea what should i do?
i'm on 2.3.4 rooted
I assume you've tried another sim card. Just send it back other wise.
Sent from my LT15i using XDA App
i put in another sim card, it works for maybe 30 minutes then same problem
so i put in yet another sim card, worked for 1hr then same problem
put in the 1st sim again, immediately problem occurs
seems like the phone remembers the sim cards that were slotted in, or it damages the sim cards in some way but the sim cards work with other phones so i'm at a blur
decided to send the phone in for servicing again, hopefully the next set wouldn't cause any problems anymore
i've had quite a few android devices and have been flashing winmo phones for years, but this is the 1st time ever i've had to send a phone in to repair!
Hello dear friends,
My Samsung captivate glide stopped receiving 3g data (mobile network not available).
Two weeks ago I had flashed Osimood ROM, all worked correctly until now.
Now I have only the wifi connection working but the Mobile network is not available at all (I cannot even call the emeregncy numbers - it gives me the "the process com.android.phone has stopped..." ).
I tried access the Settings-wireless and network-Mobile networks and it shows me "Insert SIM card".
Then I tried *#SIMLOCK# to check if my fphone is locked, it shows me "the process com.android.phone has stopped unexpectedly".
I tried to restore the phone from other backups from other Roms , but the problem is still the same.
Please help me to solve the problem and fix my phone.
#1 Thing can you make Phone calls?
#2 Verify your APN settings for Data? Is that Fine?

Try turning off your phone and re-seating the Sim card (only do this when phone is off) Then try turning on phone and seeing if you can make calls again if it still does not work try your Sim on another phone or another Sim on your phone. If unlocked any providers should work if not try from same provider.
I once had this happen to me for some reason my Sim was not properly seated. hopefully that is all that is wrong here as well. If your Sim is not being recognized, it may be hardware. Unfortunately and some people have stated issues where there Sim was not being recognized as they removed and inserted it in the past with the phone on, which could have caused some short.

Thank you dudejb for the quick answer.
I tried to re-seating the Sim card (while phone is off),
Tried to insert another Sim of other providers,
These methods didn't resolve the issue.
I never touched the Sim card before, so I think it cannot be the hardware issue.
Any another suggestions???
You could try clearing data for Phone and Phone Data (via Settings -> Apps), but I suspect that may not be good enough. If that doesn't work, use your installed recovery to wipe data. (Note, this will delete all user data on the device and reset your ROM to first-boot state!)
If it STILL doesn't work, use Kies to restore the device back to stock (Tools -> Firmware Upgrade and Initialization). If your radio works now, there was something wrong with the ROM you had, or your baseband got corrupted somehow. You can try your ROM again if you want; if the problem coems back, try a newer version or a different ROM.
If it STILL doesn't work, you're gonna have to call Samsung support. With the device in stock state they should be willing to help.
Thank you dudejb and roothorick for time and answers.
I resolve the issue by pulling out the battery and Sim card, after blow it by compressed air (dust cleaner).
My phone is back and it works like a charm

Makes sense and thank goodness (is that even a word?) Dust blocking connection to the Sim, interesting that it can do that. Glad to see it is working again.

I have an unrooted, purely stock GT-N5100.
I haven't put in the microSIM in its slot ever. I use it in airplane mode , only with Wi-Fi. But I have a problem where sometimes, it randomly detects that I have put in a SIM card( and it leaves me no option but to restart it). Then sometimes after detecting that, it detects that I have removed the SIM card and I again need to restart it. This gets really annoying and this time, it oscillated between the two cases as can be seen in the video below.
http://www.youtube.com/watch?v=Yr2UlC2VpgY
Now I don't have a SIM in the microSIM size, so I am Unable to really check by putting in a SIM card, there is nothing in the SIM slot, I checked by opening the flap.
Should I rush to the Samsung Service center to get it fixed? Any other Suggestions to fix it?

It got fixed automatically for me. Try putting in a SIM though
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.

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
Has anyone else encountered this? I have the UK version (it supports all att bands). It randomly stops detecting the sim card, and I have to eject it and reinsert it for it to detect it again.
sounds like an issue with the phone man... Mine has been flawless. if i were u i would return it... or at least try a new sim card.
I tried changing the APN settings to see if that makes a difference at all

I second this. Sometimes you just get a faulty device. Just exchange it for a new one.
have you checked the SIM card, make sure its clean? Seated correctly? You can clean the contacts carefully with alcohol wipes
