Just had a good scare - No Baseband!

I changed sims in my G2X and when I booted up I noticed it wasn't getting a signal. I went into status and the baseband showed as "unknown." I was thinking WTF. I have joined the ranks of borked basebands and I have done nothing bad to my phone. I calmly turned off the phone and switched to a sim from another carrier. To my relief the baseband was showing again and the phone connected to the cell network. I then turned it off again and put back the sim that had the baseband error. This time it worked and everything is back to as it should be. I have no idea why I got the no baseband error but it almost gave me a heart attack. Being in Thailand and no viable way to flash the baseband right now I would have been SOL if it had not been rectified.

thats crazy, your story kinda makes me wonder if the people that thought there phones were really borked maybe using the lg updater or doing whatever they were doing could have just took there sim out then put it back in and been fine...makes me wonder, i mean i understand u put a different sim in the phone also but maybe just the original sim had to be taken out and just put back in?

Does make you wonder. Doesn't it. Especially since some of the people said all of the sudden their baseband disappeared and was working before. It could be something as simple as the sim just wasn't making contact or the little computer in the sim got confused and had to be reset by being powered down by being removed from the device, let sit a bit and then reinserted?

I has issue oíd my baseband saying it was unknown after the LG updater and I took my simcard out and it came back after that I made a thread about it as well... this might be kinda funny that the fix was that easy if it is the case.

There was another thread last week where someone posted the exact same results. I'll try to find it. Baseband said Unknown so the OP powered off, removed sim card, replaced everything and powered up and baseband showed up just fine.

Right you are .. lol

Might work for some, but not all. The LG Updater destroyed my baseband, and as part of trying to fix it I got a new sim card from T-Mo but that didn't work either. Ended up sending it off to LG for repair.

[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.

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.

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.

Had to pay 10 dollars and 40 minutes of my time at the corporate store for them to tell me they couldn't give me one, had to buy one, but it fixed my OTA issue. I'm gonna rub it in the "it appears you have done this thing called rooting your phone" guy's face. No s***. I flash a new rom every hour...

Stock JB Update Hosed up my radios?

I was blissfully working just fine on my MZ602 Xoom. I would pop the Micro SIM card out of my phone and into an adapter whenever I wanted to use the Xoom. It worked flawlessly.... that is, until I updated to JellyBean. Now the Xoom will not even SEE a SIM card.
I went to Verizon store today and the guy was about as helpful as diving gear in the sahara. He said you should not be able to pop a phone SIM into a tablet and it works... well that's BS cause I've been doing it for almost 2 years. "Well, then the update must have fixed a bug that allowed you to do that"... no duh sherlock... pop a SIM in from your repository and make sure the things even works still and I'll buy a tablet package. Well, he did and it did the same thing, no connection. "Not under warranty so, sorry man". Thanks for nothing, no I don't want a new tablet!
[/Rant]
I have since flashed the ICS radios and have the same issue. I have tried stock, non stock, rooted, non-rooted, Honeycomb with ICS radios, JellyBean radios.... nothign works, it no longer sees a SIM.
Previously when I popped in a SIM it would take a minute or two and then see signal, sometimes requiring a reboot, now it doesn't even recognize that a SIM was inserted. Before even if it wasn't picking up signal and I removed the SIM it would give a warning "SIM removed, reboot?" or somethign like that.
Currently running CM10.1 with the IMM76I radios. Works on WiFi but will not see any SIM card... am I hosed? Any help?!

Anyone?
How about this... Does anyone here still use their 4G Xoom on the Verizon network?

I plan to steal sim card from my wife ipad and try if I can find my sim adaptor. Will let you know.
I can tell you that my xoom no longer shows 4g network but always did before the update even though the sim card wasn't activated.

Did you use Rogue recovery to flash the radios? TWRP and regular CWM don't flash the radios properly.

Yes, used Rogue to manually flash ICS radios to no avail.
Previous load was 100% stock, unrooted on OEM bootloader and using stock recovery so the JB updated radios original flash was done properly.

I tried the Sim card from wife's iPad and it seemed to work OK. Although it seemed to connect a lot more to the 3g network than LTE and I have very song LTE signal. Radio doesn't seem quite as good as Previous.
