27 days into the TB and since 3pm yesterday no more 3G signal. I only can get 4G when I'm in town. Not sure what happened, worked a bit with Verizon who actually thought it could be a tower issue but talked to a few friends at work they have 3G no problem. I flashed back to stock rooted, then stock no root and still same issue. Sucks at home since 4G doesn't go that far and without 3G I get no signal. Verizon said no problem take to the store and they replace.
Well its not the phone.... SIM CARD!!
Guys at the Verizon store say they have been seeing phones come in that 3g or 4g just stops working and they have been replacing the sim card. Sure enough fixed the issue. Then they tried to tell me that the LTE app could be the cause, so I removed it and dialed the number to the phone menu.. they just looked at me. Then I asked if that is the case, why did they just tell me they have been seeing phones come in that have the same problem and the sim card fixes it, I bet those phones don't toggle the 4g and 3g... They shut up.. Even Verizon TS over the phone says they know about the app and its not the problem! Oh well, get to root again tonight..
My MyTouch 4G slide has been sitting for a month or two after previously working fine. Now it powers up however it can't get a signal with my T-mobile SIM (or my wife's). I'm concerned that somehow the radio might have gotten fried. So far I've reflashed it back to stock, unrooted, and hard reset it a few times, nothing has worked.
If I go into Wireless & Networks, drop down to Mobile Networks, Then Network Operators, and "Search Networks", it takes a few moments and finds AT&T & T-Mobile (I'm in an area where my devices normally get full T-Mobile service). However when I try to connect to T-Mobile, I get a message saying "Your SIM card does not allow a connection to this network". Same SIM works fine in a G2, connected to T-Mobile.
Anyone have a way to test the phone radio, or perhaps have an idea on what it's issue is?
I have had this exact problem, and attempted the same solutions, but without success. Was working fine, and then 1hr later quit working and was not able to repair even after return to stock/deroot, etc. Doing warranted return, and just got replacement phone by mail for swap out from t-mo.
am a little worried about reroot and rerom in case I have another problem.
My device is doing the same thing. Not sure when it started... I havent used the MT4GS in a few weeks, picked it up and reset it back to stock everything, and it's not getting any service from any of my SIM cards. I unlocked it a while ago to use on AT&T prepaid SIM, and not even that will work... Any advice would be helpful...

I've used Z-Device Test by Zausan Innovacion Tecnologica to test just about everything on my phone.
I'm having a similar issue on mine after trying jupoeanutbear and failing. I have signal but data craps out at random times now.

i posted this on another website's forum yesterday...sorry for those who read it twice, but i got no responses and am desperate.
so my launch day phone had a bit of an accident last weekend the screen cracked. I was able to get another thunderbolt from someone, was originally a refurb (tag under battery says "remanufactured in Philippines" )
any who I've been using the refurb one for about a week now, no major issues. But now today I can't get LTE at all...I've tried reflashing different radios, going back to sense over CM7...nothing. Put the same sim card in another phone right next to it, LTE.
What else can I do? thanks in advance
Have you installed an app recently that is messing up the phone? Have you checked to see if LTE is active on the phone? *#*#4636#*#* and check your phone info. Could always try flashing another radio.
Why does everyone start flashing radios and performing hard resets on their phones when a signal problem shows up? Wouldn't it be wise to contact Verizon first and make sure it isn't their problem? If you haven't changed anything on your phone, there's a 99% chance that verizon is having an off day.
nothing comes to mind that i would of installed that triggered this.
tried different radios.
called verizon to see what they can do. Looks like I can get a replacement phone shipped out. Now to return to stock. thanks.

I'm surprised the VZW rep didn't tell you that it's because the 4G sim cards are paired with your phone. I tried to swap 2 4G phones on my account in the past and I was told that the 4G cards are associated to the phones and they would need to send me out new 4G sim cards. This was a while ago, so I'm not sure if it's still valid, but I would think that they'd have a way to re-link the sim cards on their end.
Good luck with this.
Yeah just another update thread. Who here is still getting the no sim error after installing the update it is now worse for me! I am more of a reader and not a poster im just curious is there a work around for this like for example has anyone installed a rom and the problem went away?
LIttle Rant: I have had nothing but motorola smartphones Droid X, Droid Bionic, Razr Maxx so I got curious since the S3 is one of the top selling phones to check it out and let me tell you love the phone but getting that stupid error all the time is annoying I picked my s3 up thinking I could make a quick sell on my razr maxx but now im stuck switching back and forth between the S3 and the razr maxx Verizon even sent me a replacement did that help? nope now its been 3 days they have a ticket open so who knows any help would be apprectiated and lets hear your story!
I'm still getting it, even worse than before I installed the new modem (radio). It seems to be more prevalent in areas where it's switching from 4g to 3g and back. If I'm in an area that has a strong 3g or 4g signal, it never gives me that problem. Has to be a Verizon thing or something with the SG3 that can't handle the switching between the two modes, just not sure......

UPDATE: I can confirm that if I place myself in a particular position in town where my phone will constantly switch between 3g and 4g and I attempt to send SMS messages my phone inevitably drops all data signal and gives me the no sim and no connectivity message.
I haven't been to were I used to get them bad....but I got one in an area yesterday where I generally get a strong 4G single that I had never had the no SIM issue before.
I was not happy.
galaxy. s3. synergy. yadda yadda.
I am getting it all the time at my house sometimes to the point where the phone does not work at all but if I drive down the road phone works flawless no errors even at work no errors im starting to think it might not be the phone it could be there network but for the hell of it lastnight I switched back from my razr maxx at home and the phone worked fine and when I woke up phone was fine im wondering if this only happens when the network is more at peak operation im growing very frustrated with this phone might off it and just use the razr maxx or hope for another update.

I had the same situation just moving from one room to another in my house. Yesterday evening I received a text from my neighbor asking if I had noticed we were receiving a 4g signal in our area (we are in a rural area about 12 miles outside of Tallahassee, FL.). Since yesterday I have a solid 4g in my home area so the no sim problem has disappeared. But there are pockets of weak coverage areas on the way to work in town and at the Florida State University where I work and I continue to find small areas where the problem persists. It has to be the SG3's inability to handle the hand-offs between 3g/4g which produce the no sim problem. My Thunderbolt would handle the switching from 3g/4g much better and not produce the no sim error. I'm sure Samsung could remedy this with a software change (at least not display the no sim) when switching service.
I still have the error on 2 phones. Funny thing is it seems that now it is worse on my wifes phone where it was the other way prior to the update.
From reading this thread and similar threads/topics regarding the sim errors with the GS3, I figured I'd post this here. This is confirmed, my friend and I both have a GS3 bought on the same day at the same VZW store. She keeps getting a sim error while I have never gotten one regardless of coverage or 3G/4G switch frequency, I frequently switch from 4G to 3G when on the subway. She went into the store and requested a new sim card, wound up arguing with the rep, according to him there's no possible way the error could be related, she finally got a new card by calling reps at various levels. After doing a factory reset and reprovisioning the internal SD card with the new sim, she has not yet had a sim error with the newest OTA. So it seems many Verizon sim cards aren't necessarily defective, but are improperly configured with the VZW network. This is just an educated guess based off personal experience, hopefully this is helpful to those with frequent sim errors.

How do you reprovision the internal SD card with the sim? If you are correct, some people may be able to fix the problem by doing so with their existing sim cards.

I would also LOVE to know how to do this!!! Very frustrated with this!! Hopefully reprovisioning the sim finally works!!
After searching around, I found to reprovision, you need to go to stock and dial this in the dialar, *2767*3855#. My question is,
- Is it def not possible to do this from an AOSP rom?
- When they say "go to stock", can I just flash a TW based rom and do it?

Agreed, I have reprovisioned before, to no avail. I thought it might be my SMS client, GO SMS, but I am getting the same NO SIM error with that client that I get with Handcent as well as the stock messaging client.
I called Verizon back today, to note my account that it's still happening, and spoke to them about a replacement phone. (I am already on my second S3 and second SIM) They offered me my choice of Android device, which currently is a bad deal. So I asked them if their deal would hold true once the Note 2 came out, and the nice lady at level 2 support said yes.
So unless this gets fixed prior to the Note 2... a switch is almost inevitable for me.
Dont waste your time doing the reprovision does not work I tried it earlier today.

Interesting...I might be doing the same thing. This issue is beyond frustrating. However, I have not called Verizon about it yet. Mainly because there doesnt seem to be a fix. I dont want a refurb S3 and there currently isnt a valid replacement. Might try the Note 2 if its possible.

call verizon just so that they can put a note in your account.
vzw put a note on my account and I should be able to just call up and replace my S3 with something new... just have to wait for something good to come out

100% agree with Ripken... call them and have them note it in your account. Basically, I am documenting it once per day (it happens more, but calling more than once per day seems redundant) so they see it, but more importantly, I have some ammunition if I finally move to a new phone. Today's call to 2nd level tech support was a bit frustrating to me, as the nice lady said that, in fact, verizon did get a bad batch of SIM cards. When I pointed out that the bad batch must have been sent all over the country, because it's not a localized issue, and there was a software update addressing it... she didn't have a response. We went thru the same rigamarole with the phone... ie pull the battery, read the number on my SIM, read the numbers from my software build, etc. Again, she offered me any Android phone in exchange, which I turned down. But, at the end, she mentioned she was sending this issue up to a different tier of support that (her words) works with Samsung to fix these issues. I kindly asked her to have them address the headphone jack - bluetooth non-coexisistance, which she giggled at but assured me was working as intended.
So, back to waiting for a fix... or an inevitable new phone.
VRLHD Modem
Ok guys try this at your own risk! I might have found a fix looks like there is another modem floatng around called VRALHD I just flashed it in odin and guess what my phone seems to be working good here at home so try this at your own risk!
Download Link:
http://goo.im/devs/invisiblek/i535/modems
also if you google VRALHD modem galaxy s3 something will come up I cant confirm for sure this will help I will report back after some usage between now and tommorow.
Here it is on rootzwiki
http://rootzwiki.com/topic/34053-of...zon-sgs3-sch-i535-odin-or-recovery-flashable/
Guess I had high hopes for that modem does not fix the issues nevermind lol I am hoping when the jellybean update hits with a new modem this will fix the problem the waiting game begins.
Installed the HD modem last night. I have one area at work that I can test it. I'll report back later with my results.
Update: Flashed the HD radio last night (in CWM touch recovery), install went fine. Didn't have an opportunity to check it out till this afternoon when I put myself in a exact known location where I could reproduce the 3g/4g constant hand-off with the "no sim" notification. Sent out 6 text messages and a couple of phone calls with no problem. Either this new radio did the trick for me or it may be coincidental that Verizon has corrected this "dead" area that would produce this problem without fail everyday I was at work. Couldn't tell you for certain. All I know is that it's not happening anymore at this particular location. I used to have the "no sim" "out of area" notifications constantly at my home until just last week when Verizon finally covered this area with a strong 4g service. Only time will tell as I travel thru areas that have weak coverage. It's very obvious that this problem stems from weak coverage areas and the SG3's inability to handle the transfers effectively.
My husband finally let me root and rom his S3 (I have a Gnex). Unlocking the bootloader and rooting (using Odin) went well. When I installed SlimBean+GApps, however, we started having an issue. He kept losing 3 & 4G signal. We didn't know about the roaming issue, so I had not backed up the IMEI. I flashed Clean Rom, and the issue is partially fixed.
The phone's signal is fine now, 3-4 bars 4G most of the time. The trouble is, we can't dial out to any numbers, and any calls to the phone go straight to voicemail. We've pulled the sim card and let it sit for a bit, but that didn't help. Dialing *228 (as Verizon tech support had him do about 4,583 times) just brings up a message about the phone being activated by the sim card, and roaming capabilities being updated. All tech support had to say was that Google Voice was probably the problem, even though we've both had it for ages with zero issues. :/
Any ideas? I don't really want to unroot and take it in to the Verizon store, but I will if there is no alternative.
EDIT: Just discovered that 4G is only working when "Preferred network mode" is set to Global, rather than LTE/CDMA.
*228 is for 3g phones only, it does absolutely nothing for LTE sim phones. Here's your solution btw.
I knew it! I kept telling them I didn't think that was supposed to do anything when I have a sim card. Crazy first string tech support. They also didn't know my battery was removable.
Will try the things listed in that link, thanks.

Haha Verizon lost credibility with me when I rented their global phone for travel last summer and when I got back to the US the instructions to get my GSIII working began with dialing *228. There wasn't even a warning about it being unnecessary for LTE sim phones.
Good luck and let me know how that goes.
