Hey guys.
I was running on the stock deodexed 2.3.3 GB rom and out of nowhere my phone freezes. I disconnect the battery and start it up but now it won't register on the network
It says "searching" on the lockscreen and I have the no signal symbol at the top.
I try to go to my network setting but it says "insert sim card to access network services"
WTF?
The sim card works in all my other phones.
I've reflashed the phone with 2.2, 2.3.4, and 2.3.3 again but nothing
I've even odin'd a couple of modems. Nothing. How is this possible?
Can someone lead me in the right direction to fixing this?
Cheers and thanks!
I'm assuming you're still on t-mobile right?
if you want to stay on a stock rom, it'll be fine for you to follow the GB Starter Pack guide I wrote. The link is in my forum signature.
Check your imei in settings. May be corrupted.

Im having the same issue did everything according to key on this link
http://androidadvices.com/how-to-update-samsung-galaxy-s-4g-to-gingerbread-2-3-3-firmware/
Worked perfectly no problems but when i load up the phone No Cell Service. Am i missing something?
If you are using an unlocked phone there is a good chance that you will need to insert your apn's manually using APN Manager from the market.
Check and see if you have an updated sim card. remove the sim card and look at the side with the gold contacts. You should see numbers printed on that side. If you have numbers then you have the new Sim card. If not you have a old Sim card that could cause issues. t mobile will update your card for free if you have an old one. Just bring it to the store.

Hey guys. I found the issue and thought I'd share. Somehow the sim reader got gummed up so I sprayed some electronics cleaner in it and worked excellent.
If anyone ever has this problem just head to your local hobby store and spray it!
Hello, I purchased a galaxy tab 7 plus in Hong Kong. All work great until 2 days ago, I inserted another Sim card then it now says no Sim card. I tried with several other Sim cards but no luck, I did a factory reset, flashed with firmware from Sam mobile but still no luck, I don't know what else to do before I send it to Samsung for repair that gonna be expensive, help is greatly wanted, thank you.

Try to insert the sim card with the tablet on. Does it restart? If not are you sure you are inserting it with the correct side?
Hello, thanks for the answer, I tried all that already, anyway the Sim only fit in one position so you cannot take wrong.
The tab restarts when inserting card yes.
I tried also taking the battery out for 10 mins... Clean the head of the Sim compartment but no luck.

Just removed the back by pushing under the sd card slot then inserted a flat tool to unclip the lid, then removed the batery connector.
However i still have the issue, its driving me crazy as it is my working tool...
does the original SIM still work in it?
perhaps try flashing original & latest frimware updates for new/different modem.
I know one chinese version of tab plus has locked bootloaded dud to China's restrictions, I would not be surprised if they have locked down modem as well.
And for the heck of it you could always try Galaxy S Unlock app, to be certain you're unlocked.
Strongly suggest backing up /EFS folder (twice) just in case.
Thanks for the suggestion, I flashed the device twice already but there is only one file. Could you direct me to the files you are referring to please I'll take a look when I'm back home, thanks again.

I would try EVERYTHING else before flashing a new modem. Toggle airplane mode. disable/enable packet data, etc.
First, does the original SIM still work?
If so I would give the Galaxy S Unlock a shot for the heck of it.
These other SIMs have you tried them in other devices to either make sure they work or activate them?
did you purchase device on a SIM contract??
sim issue
The original sim does work, i have put it in other phones and it works fine, i have also tried other sim but still same issue, message still say "please insert sim card"
I have purchased the tab sim free in hk so no, no contract, it did work fine since december until 2 days ago where i input a data only sim card, when i insert sim card it does reboot, meaning it detects the card in the socket but thats it.
Concerning Galaxy S Unlock my tab is not rooted i have used only legit firmware until now so im not sure about that.
PS: looking at my phone servie status it says:
Service State: Out of service
Are you sure you havent been sold a bad or expired sim card?
Id try to give samsung customer support a call at least, they will probably tell you to send it to them anyway.
Can you try exchanging this for another one where you puchased it?
Well, i bought it during my holidays in hk but i live in norway, so... bit difficult to chage it, the sim card works just fine in other devices so it should work in tab.
I tried the galaxy s unlock and during step 1 it says error for efs backup, so either because im not rooted or because my efs is corrupted.
Probably because youre not rooted.
Im wondering if the SIM could be from a small provider which isnt recognized by the device?
It should at least dected then say something like network provider unrecognized, etc.
I really dont what to say.
I would keep trying other sims, try to get a 5$ pre pay from a major carrier like O2, 3, tmobile, etc. not sure what carriers you have over there.
Well i use Telenor which is the biggest and also quite big in europe, i will call customer service tomorrow and hear what they say, but i fear its gonna rip my pockets...

did you push the simcard all the way to the bottom of the slot?
I need a pen to push it....so I wonder if you insert your sim card properly.

yes, since the first time, repair shop said they cannot help since device has been purchased in hong kong...
No solutions until today...
Solved
After dismantling the tab completely (hard work guys...) i confirm that the sim card reader is defect, the cushions that reads the card did not press completely on it so i applied a temporary fix by adding an extra layer to thicken the card so it can press correctly on the cushions. I did try this fix before with the tablet in one piece, however i could not get it to work correctly.
Anyway thanks for your help and i'm happy that i can use it again
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.
Hi All
I have a Galaxy Tab 2 7" Model GT-P3100 I have not used it very much as I mostly use my S3. I bought it from Hong Kong, when it was tested in the shop in HK there was no issue with anything, all worked fine. I have since brought it back to England, mostly used it on wi-fi at home, then recently I decided to get a sim card to put in it to use it out and about.
When I put the sim card in, it comes up with a message box "SIM card added - Restart your device to access the mobile network - Restart" so I click restart and wait for the reload. But it doesn't recognise the sim card and still has "No SIM - Insert SIM card" within the notifications box as ongoing.
Now if I remove the sim card from the device while it is still on, it comes with a message box "SIM card removed - The mobile network will be unavailable until you restart with a valid SIM card inserted - Restart"
This sim card I am using has been tested in other phones and it works no problem, it is a pay monthly contract with Orange. I have also tried other SIM cards in this device and have the same response from every one.
So after doing some reading online and on this forum, I rooted the Tab and then used GalaxSim Unlock to unlock the phone, thinking it may be becasue I bought it in Hong Kong, the Tab is now unlocked but still shows the symptoms above.
Is there anything else I can do to get it to recognise the SIM or do I need to unroot it and send it back to Samsung?
Any help is gratefully received.

flash a custom rom ( stable is cm10.1.2) or a customised stock rom.I thinks it will fix your prob
It is not a ROM related problem.
Go to your network operator and have your old sim card replaced with the new one (with the same number if you want). Sometimes, an old sim card just don't work with newer service. G' luck..

Thanks to you both, the sim card is new, only 2 months old. I have just flashed CM10.1.2 and not only does it not recognise the sim card, I also can't do anything as the android keyboard crashes all the time.
I am going to try to reboot with the latest nightly to see if that helps.
I am now running the latest CM 10.2 from 21.8
The SIM is still not recognised and now my PC is not recognising the Tab either.
When I first plugged it in it came up with installing drivers for Google Galaxy Nexus?? Is this normal
Hi this is the same problem I have on mine,I am starting to think it is the card reader that is the problem ? which wont be a easy job to replace for me
Might be hardware problem
use triangle away to wipe binary on downloadmode then install a stock rom and contact service center to repair it under warranty (if your device have warranty)
Just flash a different modem

I bought a house and moved.
No service in the house with Verizon.
So, I switched to AT&T.
AT&T told me I would get HSPA+ with my Verizon S3.
Well... I have 2G, voice, and text.
Anyone have an idea of how to get HSPA+ enabled? Is it possible?
I have a custom ROM, but I can flash anything if it would help.
I don't think it's possible, they run on completely different networks (CDMA Vs GSM) and the phones radios are built accordingly.

There is a way cant remember where i read it, maybe on the t-mobile forum. I recently bricked my att device and came across a verizon variant and was able to use it for att with out having it sim unlocked just a few hours ago steps taken were as follows:
After swapping the motherboards i factory reset the non rooted verizon device from the settings menu as I was just going to sell it on ebay. I had been using wifi only on a sim locked t-mobile device but the camera was not working so i switched back to the verizon and was prompted to complete the set up after i booted the device with no sim card inside. I got the no sim card message and ran the app Region Lock Away that has a red circle icon and a black unlocked pad lock by chainfire. I was skeptical 1 for the device not being rooted but tried anyway. The app said it was not able to verfiy root and closed; however once I inserted my att sim card without powering off the device i saw signal bars. Now Im not sure the app actually did anything and I might have tried the app before resetting it without success but after checking the network mode in the mobile networks tab it now shows Global as the preferred network. So i started texting people and then calling all with success. Now im still on the edge network and this may not solve your issue but I remember seeing the work around I think it has to do with correcting the APN settings but there is always a way to get things done. Keep looking you will find it. Im just happy to have cell service again but Ill be looking for the thread in a day or so as well.
Forced into an AT&T phone. It worked for 4 days then stopped. Their tech support claims the tap wasn't compatible and they don't know why it worked
I had 2g for those 4 days
I'm always on wifi but noticed my data wasn't working so not an ideal switch but if you are in a bind it does work. I'm still running at&t network on this Verizon motherboard just fine
