Lost Cell Service

I was changing my V6 Supercharger settings yesterday when I noticed my cell service crap out. I thought it was due to me changing from build.prop to local.prop, but changing the setting back did not resolve the issue. So, I unSupercharged.. nothing. Wiped data, cache, dalvik and reinstalled Tweakstockv1.1.. nothing (via CWR). Odin'd Tweakstockv1.. nothing. Odin'd Tweakstockv1.1... nothing (left battery and SIM in while Odin'ing, like I usually do).
I tried pulling the battery and SIM card but that didn't help. I checked my Verizon account - it's active.
What in the fudgeballs just happened? Does it sound like a fried SIM?

I just Odin'd Tweakstockv1 for ****s and gigs WITHOUT the battery and SIM card installed... No cell service, but mobile data came back.
What in the balllllllls?

Flash it back to stock and bring it to Verizon store.

It may just be a bad SIM card. Take the card into the store and they should replace it for free. May want to flash back stock as recommended above prior to your visit.

You might be right with the bad sim card idea. Its always been recommended to Odin without sim card in phone.
I've stumbled across people who have needed to go into Verizon and get a new sim card.
Good Luck

Guess the last thing i would try before getting new sim is to flash the radios.

Haha I forgot to mention that I flashed the EP4D radios
FML.

Can I use a coworker's SIM card to test? Or do I need a brand new one from Verizon? I'm thinking I can use another SIM card since Verizon activates via the device's IMEI?

wont work like that with Verizon. Your co-worker with have to unregister their device with that sim. Than you would have to register that sim to your phone. More hassel than your co-worker is going to want to deal with.

Ah, that's what I feared. Oh well, off to the Verizon store I go

Verizon is sending me a new phone. "The baseband kernel somehow got messed up"
They didn't even try a new SIM since the mobile data network was connected.

What on earth are you talking about? You can switch sims through 4G phones just fine. I have a Revolution and also a Charge, I can swap between them just fine. The Charge was on brothers line, but I just installed my sim and everything worked prefect

[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.

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?

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.

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.

No SIM Card

Hey everyone, I am a Galaxy Nexus user but my brother got an old Roger's S2 LTE that he wants to put on a non-Rogers network (same one I am on with my GNex). However we are having a weird issue where if we insert the original (deactivated) SIM that came with the phone it detects it. But if we put in either mine or his own it just always says "No SIM Card". I even have a pay as you go AT&T SIM that wont work in it either. So far I have flashed CyanogenMod and tried the UCLF6 radio as well as the Rogers ICS Radio UXLF3 from this thread http://forum.xda-developers.com/showthread.php?t=1754473
I should note that when my brother originally inserted his SIM he got the unlock screen and paid to unlock it through cellunlocker.net and it was recognizing his SIM at that point. Since then however we have had no luck. He even replaced the SIM card board with a new one.
Any ideas? I am leaning towards hardware issue but its odd that it still reads the original inserted SIM

did you try to go back to stock firmware and see what happened

Yep. I'm pretty sure its hardware. I got it to read again but still no signal. I have it reading my AT&T card now but again still no signal.
In fact even without a SIM card in if I search for Network Operators nothing comes up. If I do the same on my GNex I get a listing so its looking like this phone is no good
EDIT: Just realized who responded. Your threads were VERY helpful for me! Thanks so much... I'm still not convinced the phone is toast... I have a friend with a GNex on Rogers (I'm on MTS) so I will see if I can borrow his SIM and see what happens

agree, not the phone, the only way to make sure of anything is to restore to stock and do all the testing from that point on
edit: dah, its the radio, what freq is the new sim card on that wont work, is it the same as T-Mobile
edit: maybe not radio, think its like rogers, could be network settings

Actually both MTS and Rogers use the same towers so the phone should be set properly.
I've got it reading my MTS SIM now but cant pick up any networks. Its set to LTE/HSPA/GSM (Auto) and MTS is HSPA.
Is there anything that could be done to the IMEI of the phone to sort of "blacklist" it from working on any network?
Here is where I have tested from so far:
Stock before I did anything to the phone (Stock rogers GB)
CM9 Nightly
Stock Rogers ICS
SkyICS
I have also tried both the lastest AT&T Radio as well as the latest Rogers Radio. With my GNex both myself and my friend on Rogers use the same Radio (UGLC1).
At this point it seems either the radios arent working at all or the phone is blocked somehow
EDIT: Info on the MTS network... Found on the FAQ on their site:
Any unlocked devices (i.e. devices that are not tied to a specific carrier) will work with MTS SIM cards (on the MTS 4G network). However, carriers such as Rogers, Bell and Telus lock their devices to work with only their SIM cards and these devices will not work with a MTS SIM card. Similarly, MTS intends to lock our devices to our SIM cards. Therefore, our devices will not be usable on another carrier's network.
Please note that any unlocked device must support 4G North American Frequencies (850Mhz), older GSM devices will not function on our new 4G network. You can find out if your device is 4G compliant by reviewing the phone's settings.

UGLC1 never seen that radio for the skyrocket
edit: oh, for the gnex
did you try the *#2263# menu

Yes when I try that menu (*#2263#) it doesnt do anything. I can do *#*#4636#*#* when on CM9 and it works but on stock and SkyICS it just FCs when I select "Phone Information"...
I am going back to Rogers Stock ICS right now. Gotta head off to my engagement party but will likely be back at it tomorrow

shouldn't forceclose, redl and try reflashing x2 the rogers radio, wipe/format x3 in cwm b4 going back to stock ics

Will do first thing tomorrow (or tonight if I'm still in any shape to do so )
If anyone reading this thread has a stock Rogers phone can you turn it off, take out your SIM and then boot it up without a SIM in it and then do a Network Search and see if anything comes up? On my GNex I get networks but on the S2 LTE I dont. In fact I have never seen any signal from any network on this phone yet with an MTS, AT&T and an old Rogers SIM
EDIT: Actually you will probably have to be on CM9. With stock you cant get to the Network Operator section without a SIM card inserted but in CM9 you can

Ok I had enough time to do as you suggested above. Wiped like crazy then went back to stock using the ODIN method and the firmware from sammobile.
Actually I figured it out... it only FCs when I have the AT&T SIM card in and I think thats because AT&T is RAT Locked? If I have no SIM in I can get to all the menus.

k, try to set the freq(play around with it) in that menu w/out sim, then shutdown and install sim b4 restarting, left haptic to click "end" is saving

Got home and went right to work. Almost positive the problem is the radio not working now. I managed to get both SIMs reading without issue but neither will get signal of any sort (even straight after stock reflash). Gonna call it for now until I get a hold of my buddys Rogers SIM.
Thanks so much for all the help, I really appreciate it!

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.
