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.
I purchased a Galaxy s3 on ebay, SGH-i747 AT&T. ICS 4.0.4 Stock ROM
I used the sim from my old phone and chopped it down, everything worked except MMS. Here is what I've done to try to resolve the issue in order. I searched around the forums and many of the solutions that have been posted were for other types of phones or carriers, the rest didn't work for me.
1. I disabled some of the apps in the stock rom (I haven't flashed a new ROM)
2. I went to an AT&T store and got a micro sim to see if this would resolve it, nope...
3. Installed "SIM Info" from the play store and it shows "SIM Operator Name: Unknown" and "Network Operator Name: Unknown". I have another active AT&T phone (S2 with Paranoid) and SIM Info on it shows "AT&T" where the S3 shows "Unknown". Wondering if this might be the issue, but how can I fix that?
4. I checked the APN and all seems in order, I even copied the APN settings from my other phone. When I go into the network operators and search, no search option comes up, just a grayed out "default settings" thing. I'm not sure if this is normal for a stock ROM.
5. I rooted the phone and put TWRP and SuperSU on it.
6. Installed gApps (first I put on the JB edition by mistake lol, but I fixed that).
Also, I'm not sure if this is a stock rom thing, but the signal bar is always gray, not sure if it is supposed to go blue or not. I do get indicators that 4G is connecting when trying to send MMS. So what can I do? I don't want to install a new ROM on this phone because it is for my wife, but out of the box with the stock ROM MMS isn't working. Is this something that I need to take into the AT&T store and just tell them it is broken and hope they have a solution?

Does not send. Eventually fails, and I can't see any error message.
Does not receive, the download button is there, but it never downloads.
No one receives any MMS from this phone, nor any kind of indicator that a message has been sent from it.
Stock MMS and third party app (handscent) both act the same.
Bump
Any ideas? Would logs help? Where can I find them?
You chopped down the sim? As in you cut a big sim down to size?
That might be your problem...

As mentioned, I got a new sim from AT&T after I cut the old SIM down to the micro size and the problem is still there. However, I cannot rule out the SIM being the issue, since SIM Info shows the newtwork operator info as "Unknown". So I guess I should go to the carrier again and get another SIM? Internet, SMS and calls work great on it, just MMS fails. Very puzzling...

there's your problem. It doesn't communicate with google servers (grey vs blue). a little google search (or xda search) will give you the ''how to fix''. Just last week, I made a post about it here but can't remember the solutions specificly.

Ok cool, I thought it should be blue... Is this the thread you are talking about? http://forum.xda-developers.com/showthread.php?t=2102674
If so, your steps are as follows...
BWolf56 said:
1- Just restart the phone without the SIM card, and connect to some WiFi network, so you can login to your Google Account. It will log you into the account, and then you can put the SIM card back.
2- Add YouTube app and login with gmail account
Go into Gmail App and add account if needed.
Sign into Gmail account wither username and password
Go through login process
3- Hard reset your phone. You will lose all information that is currently on your phone when you do this.
Select Settings -> Security -> Factory Data Reset
Once the phone reboots, input your google account information when the phone asks for it.

I'm not sure if this will help, but I will give it a try. I am able to open all of the google apps including the play store and gmail and they are synced up correctly. The calendar seems to be having issues though, so it might also be related. Will this correct the SIM Info message of unknown network?
I tried Step 1 and 2, both passed fine, signal still gray, and still no MMS.
I am reluctant to do a hard reset, only because it is my wife's phone, and she gets annoyed when having to get her wall papers n stuff again. lol I might tell her to just deal with it at this point though. However, pending step 3, if it still doesn't work, and the SIM card still shows unknown network, what options are left? Go to the carrier?
Possible that the phone is bad, maybe that's why the seller sold it, knowing it was a bunk phone. Worst case you can send it in for warranty. Curious, are either of the water marks on the phone pink? My wife dropped a phone in the bath a while back and started having issues with the SIM randomly not being recognized and then not having data (it wasn't her s3,I think it was a vivid.)

Carrier will either factory reset your phone or give you another SIM. One last thing I can think of is that your MMS are blocked (not in your contract). So that could be something to check with your carrier (or on contract).

I doubt it's the case here as everything else but MMS works. A damaged SIM or connector won't only block those and let the rest work :silly:

Just speaking from experience, I've seen it happen first hand... voice and sms will gimp over a connection sans data, mms on the other hand won't. It was confirmed that the issue my wife had with her phone was a shorted out contact point in the SIM tray. Additionally, the op said he cut down the original SIM, it's possible he didn't do something right and physically damaged something.
I work in an profession that requires me to trouble shoot issues constantly, I learned long ago never to assume that something, regardless of how silly or implausible it may seem, May not be the culprit... we know a few facts...
the phone was purchased second hand.
The SIM card was cut and the phone is not correctly reporting the status of the SIM.
SIM has been replaced, not correcting the issue.
Apn settings have been verified.
No factory reset has been performed.
Now, SIM cards and trays can be very finicky, I have seen a couple phones with bad SIM ports... the issue the op is having may not be related to water damage, but I have seen it happen and there is no reason to discount it until verified.

Are you sure it isn't an APN issue? You might want to go into Settings -> Mobile Networks -> and Network Operators and run a search. Then you can check the APN to make sure it is set correctly for MMS.

True, if it's Straight Talk, you'll need to manually add the MMS APN. I have to do this with pretty much any phone I use, though some ROMs will include ST APN settings.
Thank you all for your input. I'm going to do a factory reset on the phone tonight (if she'll ever get off of the damn thing! lol) and I'll post an update after that. If the SIM still reports that the network is unknown, I'll get a replacement SIM. If it still doesn't work, I'll go on the hunt for a SIM port replacement, but first things first. thanks again, I'll be updating shortly.
Oh, and it hasn't gotten wet, at least the indicators don't show that it has.

Check APN's before factory reset.
I had a similar issue, I had to call AT&T and have them give me the correct settings to put in under the "message setting" option under the messaging app settings.

Can you tell me what settings those are? Also, what APN settings do you have?
Funny, MMS suddenly started working, both outgoing and incoming, but SIM Info still shows network operator unknown. :S I'm afraid that this issue is going to come back... I'm still leaning toward going into an AT&T store and getting a third SIM...
Hello. I've read many threads like this but didn't find a solution for my problem, so I start a new one, my first thread.
I've bought a Note II (N7100) international version months ago and suddenly I got the message "not registered on network", "no sim", can't access to mobile networks and so on. Further, it is impossible to access to settings>more settings>mobile networks> "INSERT SIM CARD TO ACCESS NETWORK SERVICES". For a better knowledge I found a video on youtube it explains the exact issue I'm suffering.
I got this error when I was on stock rom, so in order to fix it, I thought it was the modem, so I rooted it, installed the criskelo rom v.17 and v 18 and didn't worked. Then I installed the file "modem.tar.md5" and no results. When I try to flash that file trough odin I got a message "removed" and then the phone reboot before the "pass" message.
I have tried my sim card on a S3 and it works, have tried the s3 sim card on my note 2 and it works too. It is like my phone does not match my own sim. When I went to the carrier they tried another sim and it works on my device. I have bought a new sim card and it DOES NOT WORK. I think it's a software issue because the phone worked with other sim cards. It is quite frustrating 'cause I have this issue for about 5 months and no solution come to me. I'm consider the hammer test for my Note II if I don't fix it during this month. Can't sell it, rent, borrow or give away because the phone DOESN'T WORK AS A PHONE.
Please, some kind soul, HELP ME!!!
Sounds like a hardware issue with the SIM card reader in your phone, not making a good contact with the first SIM.
Can't you just get the first SIM replaced?
Indeed, I thought it was the sim reader so I changed it, didnt worked. As I said the phone read some sim cards so I think its not a hardware issue. Please check the vídeo I left. Thank you for your response.

I have been reading some really scary things regarding Sim Cards and viruses or malware or whatever and am wondering if I should change my sim card. A part of me thinks that the idea of a Sim card being infected is silly, but at the same time, I really would not know, lol.
If I were to upgrade my sim card...
Would it put my unlimited data at risk? (Verizon)
How would I go about changing my Sim? Could I use the sim that came with my note 4?
Also, should anyone even worry about their sim cards? o .0
SIM cards are free at corporate stores and you will not lose your unlimited.
Just take your phone in and ask for a new SIM. If they ask why tell them you've been getting errors or something. It takes like 5 minutes if there's no wait.
I don't think you can do a SIM swap online but you probably can by calling customer service from a different phone
Edit: If you call CS for a SIM swap make sure you have your other SIM on hand for the ICCID
Ah.. I see!
I actually tried to do a sim swap at home because google made it seem simple; however, it never worked to my knowledge. At first, I popped in the sim and it said that it was setting up, but never finished. While my phone was trying to activate with the new sim card, I went to the verizon wireless website and tried to activate my phone there, but could not find my phone listed in the section with previously activated phones. I did not try the option to activate a phone that wasn't registered already and just backed out. I did not - to my knowledge - see any screen indicating plan changes so I'm assuming that I did not do anything that could compromise my plan(?). When I dialed the number for activating sim cards, it went to the visual *611 screen and claimed that it did not recognize my number and asked me to log in to my verizon account. After doing so, nothing seemed to happen and it just sent me back to my home screen.
In hindsight, I probably should have stopped after it asked me to log in to my verizon account, but I suppose now all I can do is wait and ask questions to ease my anxiety x_x

You have to call that number from a different phone. Your phone doesn't hold your phone number so just popping a new SIM won't do anything.
You could try to do the "activate device" thing online but I don't know if there's an option to use a different SIM.

Cool! Now I know
Thanks for your incredible fast help!
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.

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?

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.

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.

It worked!!!

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

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
