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] 3G does not work 4G fine

Today as soon as I left a 4G area my 3G does not work. I tried everything and I get no internet connection with 3G or 1X. When I go back into a 4G area it works fine. But if I move back into a 3G area I get no internet connection. Do you think my CDMA modem is fried?

Im having a problem with mine in general where as my thunderbolt was fine. Either I have nothing, 3g and most of the time no 4g. Headed to verizon after lunch.

It's most likely your SIM card. Had the same issue and ended up with a replacement phone for no reason. Go get a new SIM from VZ and try it.

This solution may work but definitely couldn't hurt to try. I had the same problem you seem to be having, and flashed all roms and versions of software and still only 4G would work. I thought the 3G was fried and seen very few alternatives online besides new SIM or new phone. Saddened I went to bed with battery out and SIM out and as soon as I popped them in the next morning, 3G was normal and has been normal for weeks now. I can't explain it but it more than likely has something to do with the SIM card like everyone else is saying.

Dont know why but after a few days it actually started working. Thanks to all who tried to help.

Im in a 3g only area right now. Never really had the no data problem, but suddenly I am and my phone freaks out and I sometimes lose signal for 20 mins. I'm pretty sure someone from verizon said told me not to take out the sim card

I had sim card replaced and its still screwed getting replacement sent. They also had me do all kinds of other whack stuff that didnt work.

I lost 3g/internet also and tech support was going to send me another phone, but I tried the new sim card and Bingo. It worked! Thanks for the post, it saved me from having to flash my phone back to stock"for the warranty."

I did all the things they said to do, sim card,format sd card several times and new gmail account. Got replacement phone in and everything is working great so far.

[Q] Crazy situation, if anyone want to take a stab at this?

I did an ODIN flashed Gummy_GBE1.9RC1 Rom and then did a CWR flash of the MinimalGummyGBv2.0 theme over. When I went to My Verizon to switch over from my Incredible 2 to my Charge but only the SIM card registered. So now I can access 4G and get online but I can't make phone calls or send SMS/MMS over 1X or 3G.
I called Verizon they said play the waiting game. I've waited for 24 hours, activated my Incredibe again (successfully) then tried the Charge again, multiple times, (different SIMs) with no prevail, still only recieving 4G.
I just flashed the EP1W modem, and got the same results as before...
VZW then suggested a wipe... Took so long to get it the way I wanted it. lol
Just wondering if anyone else has had this happen or heard about it before?

I don't quite understand what's going on here with the My Verizon and and Incredible 2?? you had a Charge that you flashed all that to and then tried to switch phones?

When I was first starting with flashing I accidently checked "EFS CLEAR" once. That was real interesting, it caused me to lose all data services like net connection, but still let me make phone calls. I find it very interesting that your problem seems to be the complete opposite. I figured that one out after a while, but if your problem is with phone calls and texts with data working I don't think my solution would help you.
IMO you should just suck it up and odin back to stock, including the charge.pit file, and see if the problem remains.

if nothing's working you may want to follow kamikazemikes option below and get to EE4 stock and have VZ give you a new 4G sim card or a replacement phone... it happens a lot so you shouldn't have a problem doing that

No sim card error?? Any solutions??

This is not my forum, I don't have one yet, I have the bell, samsung galaxy s2 hd lte. It's a brand new device 9 days old, it started yesterday saying "no sim card inserted " I had you pull the battery and sim card then reboot, it was fine again for 12 hours now it's happened twice?? Anyone else experienced this??
Our phones are similar, bell said get a new sim, which I will tomorrow, however after a Google search this seems to be a popular error with the s2.
Thanks

Are you on the stock ROM? Are you rooted? Did you flash anything to the phone or change the ROM, Kernel, or modem? If you haven't done any of this, I would try the new SIM card. If that doesn't work, exchange the phone. If you have done something, try going back to stock and see if it resolves the issue. Alot of times it comes down to the modem / radio being mismatched to a ROM or Kernel.

im having the same problem, the way to fix it is odin flash the firmware from sammobile, buttt i cant connect my phone via usb anymore thus im stuck with this problem ;(

2 Possible Solutions(Easy Fix)
1, wait out the data outage in your area. We are on ATT and having the same exact issue and when I called 611(Customer Service) the automated answering system told me that they are currently experiencing data outages in my area. could be due to a tower/service upgrade being that 4G is coming out in more areas now.
2, call 611 and set up your phone model with the customer service rep at the technical support extension.
I would put a 3rd option... but I haven't tried flashing a new rom yet, I just got the Skyrocket as a free refurb from Insurance and I am currently on an unrooted stock GB ROM.

yes flashing to original rogers tar using odin did fix it.. but if i try other roms its broken again, so for now it looks like ill have to stay with the original firmware

If you flash the ucle2 modem in SeanZscreams post it will most likely fix the issue on each Rom you flash as long as you flash the modem after.

To check to see if its your SIM card, use a USB Adapter or microSD -> SD adapter. Back up all your files then reformat it using: https://www.sdcard.org/downloads/formatter_3/ and then put back all your stuff and try again.

try this or other plp that have this problem try this pliz an coment

The error message that said I needed to insert a valid sim card happened again today while traveling home.
The good news is I think I figured it out!
The Galaxy S4 requires a "nfc" enabled sim card!
You can't tell by looking at the tiny sim but the larger card the sim comes in has a notation of "nfc" if it's the right card.
I hung out in the Verizon store after inserting it and the drove home "an hour drive" and absolutely no errors!
And I maintained a 4g signal throughout my whole trip which was through some back country where signal is usually marginal.
This is a pretty serious problem for Verizon.
Why?
1. Because if I would have ran around in safe mode it still would have errored.
2. If I would have reformatted to factory settings... The same... All for nothing and days of configuration lost.
3. If I got another new phone, again the same.... All because I would be using my same sim card.!
I'm sure many replace the whole phone "and" sim together and when it works it's assumed the problem was the phone or software.
What a terrible headache for the customer, tech support, and verizon customer service just because people don't know the proper sim card needed for the S4!

I have the 727 galaxy ii and started having the same no sim inserted message. Running stock, never rooted or anything. Turns out my solution was to reflow the solder around the sim card and that got it going again.

[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.

But have you verified the imei shown in settings > status is the same as what is on the sticker under the battery?

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.
