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 my name is Stanley, I recently bought a Galaxy Note 2, I'm from the Dominican Republic so I'm using Claro Dominicana, which uses the same baseband as AT&T, basically instead of the signal bar, I get a circle with a straight line on it, I don't have data, I can't make calls, I can't send sms, when I try to call I get no network access message, I believe it does recognize sim because I don't get any type of error when my cellphone boots up, when I bought this cellphone it wasn't rooted, so I decided to root it and flash a rom, I'm having same issues.
Can you guys help me out please? I already have my APN information but it's not helping, I've tried flashing roms and it's not helping, I really don't know what to do, when I first bought it, I tried my sim out and it did have internet, I decided to do a factory reset through settings menu and after that I haven't been able to get any type of signal, I would deeply appreciate your help guys, I'm getting kind of desperate here.
No signal bars means no modem or a sim card for a dead account. Did you pay for any airtime?

I did try it, I'm pretty sure is unlocked because it was just working before factory reset, I guess I can try to do it again, but I'm pretty sure is unlocked.
I tried several roms and modems and nothing worked, the last thing I did was going back to stock through Odin, but I still get same circle with the line on it, a stop sign, right now I'm on 4.1.1 stock..

i don't know if this might be an issues or not, but check your IMEI. T-Mobile webpage has a method to confirm if it been blocked or not.
http://www.t-mobile.com
As of August 8th of 2013, they've re-designed their webpage.
http://www.t-mobile.com/bring-your-own-phone.html
following that link, scroll down until you see this: "Don’t see your device?" and under that, a search box. click on the link below that search box. it'll bring up a screen within the webpage. input the IMEI from your phone (*#06#) and avoid adding "/ ##" as those aren't part of the IMEI. If it report as stolen, chances are, they probably blocked it. If not, then maybe your provider doesn't support the phone itself. you might have to call customer service from your area.

I couldn't find information about my imei using that webpage, it wasn't able to locate it, I used this webpage which said is clean http://swappa.com/esn I don't know if that page is good, but it says it's clean and ready for activation.
Try a friends sim card to rule that out
If the phone worked on your network before you rooted and flashed the new rom, then I imagine you must have flashed an incompatible modem. If you flashed stock back via Odin and that didn't fix it, I'm scratching my head. Try stock again. Then remove and insert the sim or toggle airplane mode. If it worked before, stock should fix it.

Hello guys, in this case it was actually a hardware problem it seems that the internal antenna of the cellphone which receives the network signal was damaged, I'm already getting it replaced, I'll let you guys know the results.

Do you know what was damaged. Is it the wire connecting the USB flex or is it the antenna built into the back housing?
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.

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.

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?
schneiderm3709 said:
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.

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
Howdy,
About 3 weeks ago, I bought two refurbished SGH-M919 phones off eBay to replace mine and my wife's broken/old phones. Her phone was worse off, so the first one I set up was to be hers. Rooted, installed TWRP, and flashed Mokee with no issues. Put her SIM in, put her data back on, she's good to go.
I go to set the next one up for myself, do everything the exact same way, and came to realize after I put my SIM in that the phone is not connecting to LTE. Call/SMS/Wifi all work fine. I didn't notice whether or not it was doing this before rooting, recovery, and ROM.
It's giving me a "Sign-in to network" notification. I tap it, it takes me to a T-Mobile ConnectMe screen. It gives me a "Get Started" button, which I tap, and it says "We're sorry, you have switched your SIM card between different devices, so you will need to manage your account through My T-Mobile or the MyAccount app. Once you have replaced the original SIM card, you may resume managing your account through on-device account maintenance." I can only tap close. My wife's phone didn't give me this "error". I made sure the APN settings were identical between the phones, they were.
I called T-Mobile, they gave me a bit of runaround, said everything looked fine from their end, and "rebooted the connection" which didn't improve anything. They also had me verify my APN settings with them. They had me enter some different values, but it didn't change anything. They also advised me against purchasing phones from less than reputable sources. Great, thanks, that was helpful.
I switched the SIM cards between the two phones and this one is still not connecting to LTE, the other phone is. This led me to think maybe it was a hardware issue, and looked into the modem as a possibility. I found that T-Mobile updated the baseband last month on the stock 4.4.4 ROM, so I flashed that baseband and no change. Both phones were on NH7 when I received them.
I happened to notice on my T-Mobile account page that the device status is listed as "locked/unknown." So, I called T-Mobile twice today for an unlock code. The first guy was less than helpful but the second person did enter an unlock request for me, theoretically, I am currently waiting for that email to show up sometime in the next 24 hrs. But, the phone so far has not given me an unlock prompt so I'm not quite sure what I'm going to do with that unlock code once I get it. I'm also not 100% clear on whether the code is for a SIM unlock (which I shouldn't need) or what exactly. It is just the next in a series of ideas which I'm rapidly running out of. A check of the IMEI number revealed it was clean on all US carriers, with the exception of T-Mobile and Sprint which both come up as "unknown." Don't know if that means anything or not.
I'm getting ready to jam this eBay store up, but I'd really rather the phone just start working. I've been dinking with this for weeks and my frustration is mounting, especially since I can't seem to find anyone else who has had/posted about this problem before. I'm not a cell phone hobbyist or anything, and I'm just going off what I can find on Google and places like this. Any ideas/help would be appreciated.
Thanks,
Tony
I am not familiar with the issue, just some extra troubleshooting ideas...
Have you checked under the battery and confirmed the model number is SGH-M919 and the IMEI matches matches what is on the phone?
Have you checked your APN settings?
Have you tried flashing a complete full stock firmware -

IMEI under the battery matches what comes up with *#06#.
I did check on the APN settings, forgot to mention that. I edited it into the first post, added text in red:

I didn't flash a full stock firmware. I had issues flashing the non-hlos.bin to the phone, which as I understand it is the more important of the two files for my issue since it does the LTE. However, Wifi works perfect with transfer rates equal to the other phone. So, I don't know.
I'm downloading OK3 now. I read about a guy updating his modem by backing up his custom ROM, flashing a stock rom, and restoring his custom ROM. Will TWRP back up my current NH7 non-hlos.bin? If so, can I manually remove it from the recovery image without borking anything?
For your situation, just flash the full firmware. Don't remove anything from the tar. OK3 is the newest modem. Get your phone working and go from there.
Yeah, I think I'll do that when I get home, unless someone has a better idea. :fingers-crossed:

Try to flash the latest stock... Before flashing reset your device (take data/photo etc backup).... Hope that should resolve the issue....
Also what is it showing in settings > network? Is it LTE or 2G or 3G???
Sent from my SGH-M919 using Tapatalk
Thanks, that's the one I'm downloading and I'll try flashing it when I get home. It looks like it will replace TWRP and everything, bringing the phone completely back to stock?
In the mobile network settings > mobile network menu, it shows the preferred network as LTE.
Yes. It will be completely stock. If it works, you can then root and put TWRP on and go from there.
Alright, flashed the afore-linked OH3 ROM and the LTE is still broken. The phone shows up as connected to LTE, but nothing works. Play Store times out, both stock internet browsers time out. I still get the same T-Mobile nag that I got before and it still doesn't let me do anything.
Also got the unlock email from T-Mobile:
[FONT="]Thank you for taking the time to contact T-Mobile. We have received your SIM Unlock Request. Unfortunately, we are unable to process your request at this time because we are only able to provide unlock codes for T-Mobile USA handsets. Please refer your unlock request for this equipment directly to the carrier that the handset was purchased from.[/FONT]

Is there anything left to troubleshoot, or do I return it as defective?
If data works for your sim card in your wife's phone and not for your sim card in your phone, it would have to be a phone issue. You can double check if data works with your wife's sim card in your phone.
If your APN settings match your wife's phone with her data working, the last thing I can think of to try is go to Settings, under Connections go to More networks > Mobile networks and check Data roaming just in case your phone is roaming for whatever reason.
If your phone was locked on a different carrier, I don't think you would have cell service. If your IMEI was blacklisted or borked, I don't think you would have cell service.
I'd return the phone.

I will check on those two things when I get home, but my thought process was similar to yours. Both my wife's new phone and the LTE Wifi hotspot we use for our internet service have full signal on LTE everywhere in the house, so my best guess at this point is there's a hardware issue with the modem in the phone. I might look into replacing whatever board the modem is on. If it's relatively cheap, I'd rather just pay for the part instead of waiting 2-3 weeks for turnaround on the return/exchange, but I think that's probably what we're gonna end up doing.
Thanks for the help, fellas. I appreciate it.
