Sim card not detected

Lately out of the blue when I pull my phone out my pocket I see a pop up saying sim card not detected then I have 2 options. Shutdown or reboot. Is this the phone quality built a little out of place or what? I'm sure someone here has seen this message if not all of ya have.

Personally I would go to ATT and see if you can get a new sim...because apparently something is not right with the sim card.
or or or
It could be the ROM you are running, If you are running a Rom...

Running android revolution 5.1.6. Crazy how could it be the rom?

Possibly just a bad installation...
Although it is a reliable ROM they all have glitches, possibly it is the ROM and you should try re flashing it and if the problem is fixed you know it was the ROM, and if it doesnt work Like i said before, your going to have to take a trip to ATT.
It could also be some type of hardware failure in your phone, not sure though.

Have you tried using the SIM in a different phone?
Faulty SIMs aren't unheard of.

Nope just this one. It only pops up every now and then but today it did it twice back to back so now I was like wtf. And decided to ask if anybody else seen this before.

My sister once had a bad 3G SIM card that would only work on EDGE. We were right by an EDGE/3G border, so we could take 3 steps forward and have a working phone in the EDGE zone, or 3 steps back into 3G and have nothing.
My Tilt phone worked fine in both "zones," so I put in her SIM and had no signal in the 3G area, heh.

Oh.. well if the problem is persistant ill just get then to make me another similar

Uh oh...
Same problem for me here as well. Running CM7, was working fine until later in the evening when suddenly the network "died", and after several reboots noticed the little SIM problem icon next to the signal meter. I had the card locked, but went into settings and unlocked it. Now, logically if the phone couldn't read the card then technically I shouldn't have been able to change the PIN, so...
Confused over here. Is there a known fix to this? Or worse - how do I broach the subject with ATT if I have to go in?

I don't know about the fix about it, but concerning talking with AT&T, I'd recommend calling Warranty exchange first. They'll let you go through some hoops like getting your imei and possibly cleaning out your sim card with a rubber eraser. They'll also run some network tests on your phone to see if there are any "down towers" in your area. In the end, just request for a replacement sim card from them and have them note on your account that you want to get it free. Ask for confirmation if it's in your account, then head for the nearest AT&T corporate store. They'll tell you you'll have to pay $25 to get a replacement sim card or something, but just say that warranty sent you and it's noted on the account: should get you your sim for free, if possible.

I have never had a problem getting a new sim card for free from a corporate store. Just go in and ask for one.

[q] no sim issue

Having a huge issue here need some help, I recently finally got my unlock code from ATT and was very happy, I applied my unlock code with a SIM I had at work and all was good, I will be traveling out of country and had an Ekit SIM decided to test with the phone, it worked fine, then I went to put in my ATT SIM (i had it cut for microsim size, so I`m using adapter, but never had issues) and now I get the little no SIM sign and no service, interesting part is that the signal bars seemed to go up maybe just cosmetic...
I was on the ICS and then went back to SkyICS which is 2.3.5 but my modem statyed on UCLA4, I found the older 3 modem and now it shows no bars but still SIM is not working, I tried multiple SIM cards and always show the SIM symbols and when I go to mobile networks it says SIM is not present. Please help me as this is my primary phone and Im stuck, I really wouldnt like to reset everything.

If it was me I'd make a nandroid backup, then ODIN flash the Samsung official stock I727 UCKJ2 2.3.5 firmware from sammobile here. After flashing stock, booted into stock e3 recovery and do a wipe data/factory reset and see if that resolves the 'no sim' issue. If the phone still doesn't recognize the AT&T sim, take it into an AT&T store and request a new sim card. If it's still borked even with a new sim card they should swap it under warranty.

I guess I have to try to go to Stock, no choice here, I know its not the SIM tried in wifes phone and its fine, also that EKit SIM that just worked in the phone does not, could I some how damaged the SIM card holder ?

Sounds like it could be the sim slot. Anyway, if you put it back to stock you'll have not issues at the store when you swap it. Then restore your nandroid backup on the new phone.

Only thing is I bought this phone on ebay back in January, its registered under my account and everything, and I got it brand new. I hope ATT will repair/replace under warranty. Sad thing is I was fighting with ATT for 2 weeks to get this phone unlocked and finally got it now I have to swap it and go thru the same process .
I dont get how this happened, this is not the first time I swap SIMs and all was good, I think its pretty hard to break a SIM slot, but I guess I did it some how. So Pissed off right now its not even funny

Just as a long shot, maybe try cleaning the sim card contacts with a pink pencil eraser. Sounds crazy, but I have a Garmin running watch and the contacts on the back sometimes get dirty and it won't sync with my PC, so I just 'erase' them a bit and it's back in action.
If AT&T won't do the warranty swap, Samsung will directly-- although that's a little more of a hassle. Good luck!

The card and the slot contacts, if you can get at them.
Also, you said the card is cut and in an adapter - maybe it's just not quite lining up with the slot pins. Try it with the card not quite fully pushed into the slot.

I cant even backup current ROM, it gets to somewhere on the data part and trows me back to recovery, been doing this for the last hour, getting really frustrated and tired !

Maybe it's time to punt and flash stock 2.3.5 with factory reset.

Yep was able to backup and flash stock from here http://forum.xda-developers.com/showthread.php?t=1342348. still same no sim, I cleaned the SIM and the slot, even tried with some compressed air nothing all the same... I guess I`ll go to ATT store, do they usually replace phones on the spot ? I`m used to going to apple store where they just replace it... This really sucks !

I don't know if this will help, but have you tried manually inputting the APN for whatever carrier SIM you have at the moment? It's worth a shot
Edit: and are they LTE SIMS?

I would do that, but when I go to mobile networks I can't get to setting, it's says Insert sim to change mobile network settings.
The SIMs worked fine before yesterday. 1 is ATT lte 1 is not, but again it says no sim inserted.

sim card removed?

I'm in India right now on vacation. I own a rogers s2 lte. Recently I've been getting random popup messages saying my Sim card has been removed and i need to restart the phone. Thing is I did remove the Sim card for a minute or so a few days ago but I'm still on the same rogers Sim card and the phone is in flight mode the entire time. Its annoying for this to happen. Any ideas?

It could be a ROM or radio issue. Could also be a sim card slot issue, bent or broken pins etc.

Wish I could help, but you need to give more info. Are you running stock or a rom? Have you dropped it recently? It could be software or hardware, but nobody can help you if you don't give any info.

[Q] Network connection cuts out - Not registered on network

I have read a few threads about this issue, but none of them seem to be the same exact problem..
Right now I am running ParanoidAndroid 2.15 with InstigatorX 6.3.6 kernel.
When I first noticed the problem I was on PA 2.13/IX 6.3.6 I believe and I was using the UCLF6 modem.
My network connection was fine until one day I noticed that I had 0 connectivity and when I tried to make a phone call it said I wasn't registered on the network.
Sooo the issue..
My network connection constantly shows that I am not connected to the ATT network, sometimes the network is out for a good 5 minutes or so before it connects to it again. When it does connect to the network it usually shows up as connected to the Edge network..once in a while it will show 3g; I used to have full bars of 4g/hspa.
After a few minutes go by, the network connection cuts off and I am again once disconnected from the network.
From the time I had no problem with my connection to when it started disconnecting from the network I have no idea what happened.
Yes, I do flash ROMs a lot, but this seemed to happen over night. (I had not messed with my ROM for a good while and then BAM my network blows 'all of a sudden')
Things I have tried..
I have tried different roms, different modems, I have tried the whole airplane mode deal, tried pulling the batter, I have reverted back to stock using Odin and the stock ROM file. My IMEI number shows up correctly, my settings are default as far as allowing data connections ect.
I am not sure if there is anything I can do besides call up the warranty department and try and get a new phone, but I wanted to ask here before I did that.. I've already returned my phone like 2 or 3 times since February lol.

Try getting a new SIM card from AT&T. There is a $10 fee for it, but I had a similar problem and this fixed it for me. My phone would lose service and say "No SIM card inserted" then I would hit restart and everything would work except phone calls. I had to remove the SIM for a few minutes and put it back in in order to make or receive calls.

Not sure if this will help or not, but in the past I have had AT&T "re-initialize" my phone on their end and it has fixed some connectivity issues.
Good luck!

Well dang, I was wishing and a praying I'd come back to some good news lol. Oh well

Backup and odin back to stock I727UCLF6 and see if the problem goes away. If yes then its possible you need to look for the AT&T LTE APN settings.

I've tried using Odin to stock ICS and also GB, but the problem still occurs =\

Did you unlock it?
Hey,
Did you unlock the phone? I have a similar issue, having had tried many different modems kernels and ROMs including the stock ones. It turns out that if the phone is unlocked then it will lose connectivity to lte and 3g. I get edge sometimes and one bar max but I cannot make a call out ever.
Unlocked it as I was travelling in the states and now Roger's says I voided my warranty by unlocking it. Tried a different sim card but I am only able to text right now, no calls. The only silver lining is the big three are starting to lower their prices a bit to compete with new competitors.Then again they make budget brands like koodo and public mobile to directly compete with the new entrants so unless the crtc steps in looks like we'll always get gouged.

I'm not 100%, but I don't have any warnings about my SIM card or anything

Same boat
I'm having the same issue with my Galaxy Note 717r on Canadian carriers Rogers and Telus
I keep getting the Error 'Not registered on Network'
On Rogers, if I select GSM only, it will register on the Network and connect with EDGE speeds
It has been Carrier unlocked at some point but it was working that way for a while. You can check by using this service code: *#7465625#
Tried multiple SIM cards that work with other phones.
Verified that the IMEI number matches what is on the sticker *#06# Rogers told me if I can make calls on the GSM network than the IMEI isn't blocked. Don't know if that's true but it makes sense.
Went back to stock everything (Modem, CSC, ROM) then I upgraded to ICS OTA.
Enable SIM lock, Disabled SIM lock.
How do you know that carrier unlocking blocks you on the 3G/LTE networks? Can the carrier be relocked?
I've got another 717r coming to me. I think I'll try backing up the EFS folder and restoring it on this phone just to verify it's not corrupt or a blocked IMEI.

I'm not sure about that one.
But what ROM do you use? It seems like this only happens with people who have JB ROMs..it looks like..
I just called ATT , they did some kind of wireless number reset, nothing happened.
They are going to send me a new SIM card which I can test and see if that fixes the problem, but I'm not going to hold my breath though.

sgs3 is eating SIM cards

How many people have had to get a new SIM card to get their phone working properly?
How many different reasons have a new SIM card been needed for?
I've heard of a lot of people needing a new SIM card to receive the OTA.
I had to get a new SIM card as my phone would no longer switch to 4G.
Is there a hardware or software issue with this phone causing SIM cards to malfunction?
Is there anyone who's needed a SIM card replaced that has Not flashed or rooted their phone in anyway?
thanks,

I needed one to be able to check for updates.

Do you root and flash roms or other things on your phone?
I'd like to narrow down if this only happens on phones where that is done.
and then to nail down what we are flashing that is wrecking these sim cards if that is the common factor.

I had to get one once I went back to stock to receive ota. I do run a custom rom normally.

Mine is fine, but the other three in my household after receiving g7 can no longer check for updates. I wonder if Samsungs "no sim fix" somehow killed them. All three are unrooted, and never have been.
I have not yet replaced their sims.

Odin'd back to stock to receive updates, had to get a new sim in order for it to work. I run custom as well. I think it has something to do with how the sims are identified on the LTE network since Sprint and At&t don't have this issue.

Never rooted or ran a custom rom...100% stock. Someone mentioned that the update may have fried the sim cards....that's my thought as well.

Problem with that theory though is lots of people had to get a new sim card just to be able to take the ota.
Good to know this isn't necessarily cause from flashing roms and what not.

I also had the problem checking for OTA updates. I received the update just fine and then had the problem. I went to the Verizon store and the switched the SIM card out and problem was resolved.

Both my brother and I had to get new sim cards for 4g due to the phone warping our cards.

I had to get a new sim card when I upgraded from the galaxy nexus to the gs3. I believe it was because I had done a manual prl update when it was in the nexus. it seemed to work just fine in that phone but once I put it in the gs3 I couldn't get 4g unless I switched to 4g only.

I was on the latest OTA and I hadn't checked for an OTA since Oct. 3rd and tried yesterday and got a error. Went to Verizon and he said he didn't know if any issue with SIM cards being fried with GS3. I'm all stock and he argued that a new SIM wouldn't fix. I got him to do it anyways and now checking for updates works again. He still doesn't think it was a SIM card. But i beg to differ.
