Loss of Service - No SIM Card? - Galaxy S III Q&A, (US Carriers)

I've been using my Verizon Samsung Galaxy SIII for the past few days and three times I've been using the data connection and all of a sudden, it would lose data...
In the notification bar, it would flash "No SIM Card" and then would begin searching for service. It would take about 30 seconds to a minute to regain full service.
Is anyone else getting this issue?

I have been getting that also. My phone is constantly freezing and rebooting. I am getting ready to flash back to stock to make sure my phone isn't dorked.

Hi guys, i'm having the exact same issue! While I'm at my house (3G area, not 4G) when I go to hit talk it immediately drops from 3 signals to the no signal symbol, then I get the No SIM card message too. After a few seconds it'll bounce back and show full signal again. I troubleshooted over the phone with techsupport last night and they recommended to swap out the SIM card or the phone. Went to the local store this morning for a SIM swap and it was better but not 100% fixed while I was at work (10miles from home). Stopped at the store again after work and after some arguing convinced them to replacement (phone would not act up at the store in the 4G area at all, was rock solid). Just got home and again with the new phone and a 3rd SIM card its doing it. I'm not sure what to think now. There were 2 other people in the store complaining of the same issue when I was there, all galaxy s3s. Wondering if its a tower issue in the area (Poughkeepsie, NY area) or software problem. Seems hard to believe its a network issue if the phone itself thinks there's no SIM card in it (and previous phones in the same area worked fine). Maybe some kind of software / firmware issue?
I'm really bummed out. My mom and sister just got the same phone and no problems in Chicago and Detroit areas. What areas are you having issues in? Hopefully we can get more info going, not many postings about this on the web yet....

I really don't want to send this thing back...

Just an update, this happens when I send text messages. It doesn't happen every time, but it just did it twice in a row.

if you still have IMEI go change your sim card.

Anyone with signal or "not registered on network"

Hey guys, I live in south florida and I dont know if this issue is with my phone or othera but sometimes areas were I get 3g I dont get any bars or it doesnt say searching yet when I try to make a call it gives be the not registered error. I did go into the mobile network setting to fix it and it didnt register. Anyone know a fix?
Im using truestock 2.1 and lagfix.

I live in south Florida too and the only problem that I have with network is under about phone, my phone number is displayed as unknown. It only becomes a pain when I try to use apparently like push-to-talk.
I think you should talk to a tmo representative or bring your phone back to the store.

I'd reccomend trying your sim in another phone, if possible. See if it still has signal problems or works perfectly. Also, if you're using an older sim, update your sim to the one that came with it. For some reason the vibrants seem really grumpy with older sims a lot of the time, but not in all cases. I'd say it's helped about 75% of the customers (and myself) that have had issues with signal/reception on it.

[Q] Full 4g data working, but not voice

Ok, so i'm new to this whole android thing and came up on a TB. Sorry for the noobness of this...i did a search, but couldn't find anything relating to my problem. hoping someone could give some advice.
I tried to activate it the other day and it took some time to activate(i guess Verizon's network was down), but the 4g LTE was fully functioning. Phone was recognized on my account at verizon and everything checked out.
however, when i tried to make a phone call, i got the message 'welcome to verizon wireless. your phone number is not active or invalid'. one thing i did notice was the roaming triangle above the signal bars. btw, i did try contacting verizon and they didn't know what was going on..they kept blaming the downed network.
i couldn't get it to work so i had to switch back to my whackberry.
Anyone know what the problem is and how to activate it? any advice would be awesome!
thanks for the help in advance!

no service on galaxy s2 sgh-i777?

hey guys my galaxy s2 is currently on shostock2
and the imei is there and everything i get like 2 bars as service but it says emergency call only and i tryed GS11_repair and hc-ktool
i just cant figure out why i get no service and its unlocked i have a tmobile sim card in it but i cant make calls or nothing everything else works fine except it wont connect to tmobiles mobile network i think in network operators tmobile doesnt even show up only at&t
if some one can help me resolve this issue it would be greatly appreciated thanks you
Go under mobile networks and do a carrier search and see if T-Mobile pops up. Are you in a good coverage area? If it says emergency only then you're probably connected to AT&T towers (which shows your radio works, so that's not the issue)
settings -> more (under wireless and network) -> mobile networks -> Network operators -> scan for networks
I did man only at&t shows up

Yeah, that just sounds like you're having crappy T-mo coverage. You could try flashing a different modem.
I just did I get bars but its still in emergency call only
Sent from my SGH-I777 using xda premium
Even though you have bars, doesn't guarantee that you are on the T-Mobile network. You can also get bars on other networks if T-Mobile isn't available. This has happened to me before when I drove off in the mountains, and only AT&T was available (I'm on T-Mobile), and I got 4 bars, but it still said "Emergency Calls Only" because I was on the wrong operator.
the problem with my device I never get more than 3 bars

Hey. Yani. Did you solve your problem?
Because I have same issue as you have.
I heard from one of my friend that upgrading gingerbread to ICS might work, so I did that as well. but still the same.
And just to let people know, I am not in the crappy tmboile coverage area. In my other phone, I get five full bar reception with same tmobile sim card.
Any ideas?????
Different phones have different radios, get different amounts of service.
Unless your 'other' phone is another i777, theres nothing to compare.
does it really matter how good of service you get when you only get edge?
APN settings
Did you input the APN settings for T-Mobile? I unlocked mine and run it on Straight-Talk and I had to manually input the APN setting to get it to make and receive calls. Just speaking from my personal experience I would choose Straight-Talk over T-Mobile. You still get the same service as AT&T but its only $45 a month for unlimited everything including data. Just check your APN settings man. Make sure your T-Mobile one is selected if you've already input everything.

Yeah. I tried that and getting a little bit better service. I will try it on Monday because at work see if it is better.
If it doesn't, I guess I have to sell this phone, since I tried almost everything I could.
Thanks for letting me know about Straight-Talk, but I have to stay on T-Mobile. I had a deal with T-Mobile for $100 unlimited txt and data for 4 lines. So I can't switch over for 2 yrs....
anyway, thnx for the advice and will update on Monday night.
Any Resolution?

Hey shpchunjae, did you ever get this figured out? I'm fighting the same problem now (trying to get my i777 to connect to the T-Mobile network) and I'm not getting anything - voice, text, or data. The SIM card works in another T-Mobile phone, so that's not the issue.
Thanks!

No Data Connection after Connecting to WiFi for long time

My DNA just has the Voice service after connecting to WiFi over night. The first thing I need to do after leaving home is flight mode on and off to get the phone back on the carrier's network data. It is annoying, Am I the only one here?

I get the same problem. I have also experienced "preparing sim card" messaged several times. I hope the OTA update helps, I have not had the chance to install it as I am currently studying abroad.

Have you tried in gsm only mode? I have same problem and preparing SIM card issue doesn't come up in 2g mode. I was reading this kind of issue is produced most likely by a faulty 3g antenna.
Sent from my HTC6435LVW using xda app-developers app
I experience this problem frequently too. Not sure if there really is a fix for it. Toggling between airplane mode works for some people, reseating the SIM card, gently erasing the back of the sim card, applying 2 layers of tape to the sim card tray to keep the card seated appropriately, exchanging for a new SIM, putting phone into airplane phone and removing sim than replacing sim card, remove sim card than boot into recovery and clear cache and dalvik, etc.. yes I've tried most of these but to no avail. The OTA update may have helped a little I am not sure. Most believe it is a hardware issue that really can't be permanently fixed. If anything else is found let us know. Such an annoying problem that totally ruins this amazing phone.
There's different issues being discussed here. It sounds like you're having the issue where you need to toggle airplane or network sometimes when switching between networks or from WiFi to mobile data.
It's not device specific, there's some decent articles on it and in the early days we thought it was a Verizon issue. But it's actually a Sprint problem too I learned on accident when I was trolling their forums.
When the network is activated, on a device with a SIM card on Verizons network, the preparing SIM notification is actually describing a process very similar to *228 back in the olden days before LTE that was done when first activating a device on the CDMA network. The LTE network is different in that everytime it connects to the network is does that SIM activation process.
I know on my networks here, there's a changeover in one place it happens about 50 percent of the time.
If that's what is happening to you and toggling airplane fixes it, I think it's an LTE/network symptom and not due to a faulty device.
However I have a device I'm about to warranty with a hardware failure I'm thinking. It gets data great but absolutely no voice ever, never had an incoming call or anything. Or made an outgoing call in the month I've had it. It doesn't bother me I didn't buy this thing to talk on, but I'm donating the device so I'm going to have it fixed.
Anyway, from all the OP has posted so far, I'm not feeling like it's a hardware or device issue, however as more info develops that opinion may evolve.

U r the man Charlie. I am having an identical issue as op. And based on occurrences relevant to location it seems that this is only an issue when under 4g service-atleast for me-. Toggling airplane mode reactivates SIM as u said and restores full functionality. However, I have noticed the time needed to pass for said issue to reoccur is significantly shorter unless a full restart is preformed. If fastboot is enabled the issue persists. My question is this; if this is a network issue -which I'm sure it is at least in part- what software wise -if anything- could be going on a full restart fixes?

I'm a gsm user and I'm having the issue in a non 4g lte network. I have preparing SIM card every couple of minutes. If I toggle to gsm only mode everything is perfect, not even a single issue. Looking to the logcat, when the error comes up, it shows a message about ICCID number doesn't match stored one and then invalid radio technology. Is this software or hardware? I'm really confused. I've already tried everything from software side, kernels, radios, roms, RUU to stock.

[Q] Samsung Galaxy S5 losing network connectivity

My wife and I both have brand new Galaxy S5s, and we both intermittently experience this problem. One of us will send a text message to the other, the text will show as being sent, but the other person doesn't receive it. If the person set to receive the message reboots their phone, the message comes through (as well as any other "pending" messages), and normal phone use continues for a few days until this issue returns. Rebooting seems to always fix the issue temporarily.
This of course is not limited to just communication between our phones, but I was using that as an example. Often times, I'll reboot my phone, and realize I have 3 new text messages, and 2 voicemails from yesterday. Very frustrating.
Phone calls are also affected. When these symptoms are present, phone calls cannot be placed or received until the phone is rebooted. Incoming calls go directly to voicemail.
The worst part of it is, there is no easy way to tell our phones are not connected to the network. The reception status shows good connectivity. Most of the time we're connected to wifi, so email and browsing the internet still work.
I'm just wondering if other people are experiencing this, or have any suggestions of some things we can try. Thanks for the help.

Well, that was very timely. I'm glad they released a fix the same day I decided to ask for help. I appreciate the link, and I'll install it and see how it works out. Cheers.
The update killed a lot of people's data speeds. I made a ticket with t-mobile techs. I suggest anyone else with bad data speeds after the new update do the same.

From what I know T-Mobile doesn't care if your phone is rooted because you're not doing any warranty service. If that was the case they will probably tell you that its voided.. I have seen a few that root their own phones at their job so I doubt it'll be a problem. But I guess every T-Mobile store isn't the same..

Yes this is the exact problem I had with last GS5. Tmobile replaced it and I still have this problem with the new GS5. The tried to tell me it was just how the old GS5 settings were set. They had me do Factory reset many times, it never helped. Now with the replacement GS5 the exact same problem. Like you everything looks great on the display. I would just get calls on my home line wanting to know why I never answer my mobile phone. The only thing that helps me is a restart but it is only temporary. Do you know if they have released a fix for this problem?

The only thing it seems the tmobile employees know how to do is a factory reset .. That is their solution for about everything . Like the other guy said they dont handle warranty . That is for your samsung warranty when knox is tripped . If you have handset protection nothing voids it from what i have seen . I think tmobile would rather replace a rooted phone than one with a cracked screen .
