I just purchased the sII skyrocket 2 weeks back. About every 2 days the phone would stop receiving calls. When i get a call it would ring a half ring and then at the top where it shows the signal would have a no sign on it like there was no service. Once its goes in to this mode it would stay in it until i reboot the phone. The problem is that i never actually know who is calling because it never logs a missed call. This is the first i have seen this on any andriod phone. Here is some additional info, Stock Rom, Phone is rooted, i have the following apps frozen using TBP
Allshare
At&T code canner
At&T hotspots
At&T navigator
At&T ready 2 Go
Featured Apps
Kies Air
Kies via Wifi
Kobo
NFC service
NFC Test
QIK Lite
QuickOffice
Social Hub
Tethering Manager
Any thoughts? I should add that its not specific to one contact it will happen to anyone that calls, i have tested this calling from my wifes cell to mine when it was in this mode and saw it happen constantly. Rebooted sitting in the same place phone received calls.
no feedback yet from community but i thought i would post an updated.
I contacted AT&T that suggested it could be the SIM card, I went to the store tonight and changed out my SIM. I will update this if the issue goes away so in case some one has something similar they know what a potential fix could be.
Interesting.
Did you get a new SIM card when you get the Skyrocket as well?
I know they issued me a new SIM card at purchase because of the LTE upgrade.
yep they gave me a new sim card when i purchased it said the old one wasn't compatible. So the one i just received replaced the new one that is about 10 days old.
just to update this, this seemed to have fully fixed my issue.. since i swapped the sim there have been no issue
Your SIM was probably dying out, it happens.
Glad to see your issue was fixed, I was thinking you were having LOS, same as the Sprint SGS II.
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.
Yesterday, I received a new StraightTalk MicroSIM (ATT compatible) for my new Nexus 5. I have been using a StraightTalk T-Mobile compatible one that I used in my old phone. I activated the new SIM, using the automated phone system. This morning I saw that my phone still had no service. That is, zero bars, I cannot make calls or text. Of course data doesn't work either. I logged into my account and it said that the transfer to the new SIM is complete. So I called StraightTalk and was transferred 5 times to people who did the same trouble shooting with me every time. Their trouble shooting: power off your phone, take out your SIM and then start it back up. Then they said they need to send me a new SIM card.... Here is my issue, I feel like they don't know what they are doing so their answer is just to send me another SIM.
My question: Did anyone else have this experience or ideas on getting the phone to work? I've tried different APNs with no different results.
Okay, this is odd. I figured, since I won't have phone service for a while, I would root my phone. After I rooted my phone, everything works. I can make calls and data works. Not sure what changed but when the device was rooted, it also did a factory reset. After 50 minutes of crappy customer service, I think I'll just take the new SIM card they are sending.
Takes a while for them to activate it sometimes. I was with customer services for 2 hours trying to activate my Sim card because it wouldn't let me online.
Their customer service, signal penetration might suck, but it's way cheaper, which I'm good with.

I wonder if maybe that is what happened but I think it probably had to do with the factory reset.
I do want to post one final thing since everything has played out today... On the phone I asked them to expedite the package since this is my work phone and ONLY phone. Today, FedEx delivered a new SIM card... it was the card only. No other packaging or information. It was the wrong SIM... I needed a micro and they sent a regular SIM... but at least they tried. After receiving the SIM today, I don't feel so bad about the situation. Things may have been different if my phone didn't miraculously start working. I would have had to cut down the regular sized SIM... to find out if it is an ATT or Tmobile version... it's probably the Tmobile versions, since I ordered the ATT version. Thats how things go... have a good day!
READ THE NEXT POST FOR CONTINUED ISSUES
*** I'm going to keep posting my experience, in case anyone else can find the information useful. ***
My service should have Auto-Refilled today. However, when I went to make a call, I found out my service was deactivated. I thought maybe Auto-Refill was disabled when I transferred to the new microSIM. Unfortunately, after spending another 45 minutes on the phone with customer service, I found out that they activated the replacement SIM that they sent me... the one that doesn't fit my phone and appears to be a Tmobile SIM. So, instead of just re-activating the microSIM that was working yesterday, they have to send me another one. I confirmed with them that they will be sending an AT&T compatible microSIM. We will see what I receive.
I have seen similar posts of this issue with the Z3 and Z3C, but I wanted to post my experiences and see if anyone that has this issue has been able to resolve it.
I have an unlocked D6603 that I purchased directly from Sony US. When I received it, I got a new LTE SIM from AT&T, but did not give them the IMEI from the Z3. I activated the SIM and still have my old phone's IMEI listed as the device (LG G3). I inserted the SIM card, downloaded the APN settings, rebooted the phone, and everything was working great.
When I got home from work the next day, my wife said that she had called and sent me text messages that I did not receive. I rebooted the phone and all of her texts (as well as texts from other people) came through. This happens almost every day, and sometimes multiple times in one day. I either have to reboot the phone or change the network settings from LTE to WCDMA for the texts to come through.
One thing just noticed while making an incoming call.. My Z3 has full LTE signal, but when the call is coming in, it immediately switches to HSPA, and when the call is disconnected, it immediately switches back to LTE. Not sure if that's normal behavior or not, but figured I would include it in this post.
Same issues with AT&T. Intermittent calls and texts. It's thanks to AT&T's archaic verification system. Because you don't have a bloated AT&T issued device, you need to keep your old (AT&T issued device) IMEI to be able to get LTE signal for data. If you give them your current Z3 IMEI, you will always receive your texts and calls on time but you will not be able to get LTE because your IMEI is not registered in their database. It's a classic case of a carrier advertising "bring your own devices to our network but we won't load your IMEI so you can access the services you actually pay for", pathetic. T-mobile and Verizon actually offer the device but AT&T won't. Also, AT&T does not offer voice over LTE so your calls will always be 3G (H or H+) when connected and when disconnected your phone will go back to LTE for data. You have two choices with the extortion king, AT&T. Update IMEI and get all calls and texts in a timely matter while forfeiting LTE or leaving your old IMEI and get LTE but miss calls and texts. Ridiculous.
My situation is exactly like the op except i dont miss calls and recieve all my text, so something must not be right, have u tried flashing a differnt ftf?
Multiple, doesn't change anything.
Has anyone tried to use a Z3 IMEI in the last month? I know that when it first came out, it was an unrecognized device for purposes of LTE, but at some point that will change. For example, I am using a Z2's IMEI right now, and that certainly is not an AT&T device.

I changed the IMEI on my AT&T account to match my Z3's IMEI, since I would prefer to receive all of my calls and texts over having LTE. After making the change and rebooting my Z3, I still had an LTE connection and I did not experience the missed calls/texts for a few days. Yesterday, I did not receive any texts or calls so I rebooted the Z3 and texts started coming through. So it appears that using the Z3's IMEI is still preventing calls and texts from arriving.

After adding the Z3's IMEI, it is still showing as an unknown device with AT&T, yet it does get an LTE connection.

I just picked up a Z3 straight from a Sony store last week, stopped by an AT&T store first to get a nano sim which they handed me with no question asked but I didn't activate right away as I still had my ion on....
Once back home inserted the nano sim in the Z3 called AT&T to activate the sim, they sent me a text to verify my account and the settings were downloaded to the phone, they asked me if it was a new phone, just told them no just a new sim in my old phone...right away I noticed that I didn't have LTE at all, so went into the APN setting which were a bit different that what I had in the xperia ion, deleted the APN that was downloaded by AT&T to my phone and entered the ion settings manually into the Z3 and right away LTE was back....not a single problem receiving calls/texts and LTE on full time since then...

The same issue is affecting me too. I also have the D6603 on AT&T network. Don't bother asking AT&T for help, they will say nothing is wrong w/ their network (which I think is technically correct). This sucks because I was motivated by their bring your own device promotion only to be disappointed that they can't help resolve this issue.
Anyway, turning LTE off made the calls and texts more timely for me. So the easy workaround is to add the LTE toggle quick setting button so you don't need to click a few places to get into settings > more... > mobile network setting > network mode > to turn off LTE. This should default you to WCDMA/GSM when LTE is off by the way. I think the speed is somewhere between 3G and definitely not as fast as LTE, but not unbearable either.
This is still a pain in the butt given that we freaking PAY for LTE, but it's a simple work around (for now at least...)

I did try your APN settings, which seemed to work at first, but the issue came back after a day or two.
I contacted Sony about it and they are placing the blame on AT&T. They also had me do a software repair using the Sony PC Companion software. I'll have to test it for a day or two to see if I continue to have problems or not.

still receiving calls and texts just fine but can't answer anymore as I have a different problem now...the phone took a dive from a cliff (literally)
First time I drop and break a phone but also first that I buy insurance, took the" protection plus" when I was at the Sony store, kinda hesitated at first but went for it finally, glad I did now, getting a new one mailed and waiting for it to arrive...
My issue was fixed
I had the same problem for the longest time with all official roms and Slipsystem's. I installed the unofficial CM 12 and the problem disappeared. It is something in the official stuff that messes with it.
I'm on att and don't have this issue at all. Store used a s5 imei when i switched
I have to disagree with some of the comments above. I'm on a D6603 in Texas purchased from the Sony online store several months ago. Had to go to a store to get the new sim card anyway and the salesman registered the phone using the IMEI off the box. The Z3 was added as a new phone on the account (I wanted to take my time moving stuff plus I intended to port my old number to Google Voice anyway). I did the setting option to download the APN myself a few minutes later. The Z3 shows as unknown model on ATT online but LTE data works fine and I've had no problems receiving/making calls or messages. So, using the z3's real IMEI is NOT the problem. Perhaps the problem is some setting that doesn't get reset properly when switching an existing phone whereas adding it as a new line avoided that?
@svnyster @augie7107 @pbsteebs @nirvanayoda have you found a solution to this problem?
here's my experience.
1. I have a straight talk sim card (it uses ATT network) and I experience the same problem.
2. My Xperia Z3 D6603 has LTE coverage, but after a while - even with signal at 2/3 bars - it doesn't receive calls or texts until I restart it, switch airplane mode on/off, or toggle LTE/3G.
3. I know for sure this is not related to the rom I'm using: the phone was in stock conditions (kitkat 4.4), then I rooted and installed a debloated stock lollipop rom... still the same problem.
4. I also know that this is not a sim card issue: we have 2 Xperia Z3 phone (one is my wife's). If I swap my sim card in her phone I have no problem, and call and sms get through. So only one of our Z3's is affected by this problem.
5. Finally, the only way I found to work around this was to switch to WCDMA (preferred)/GSM (instead of LTE preferred/WCDMA/GSM). In this case i receive all calls and sms but I have to give up LTE.....
Any thoughts?
Thanks a lot for your help!

I actually ended up switching devices, because I was unable to do my daily work without consistent LTE, and I got tired to switching between LTE and WCDMA.
Everything I read from AT&T shows that the LTE bands they use are 2, 4, 5, and 17, which the D6603 has all of those bands. However, my new device (Samsung Galaxy Note 4) also includes LTE Band 12, which the D6603 does not support. I know that Band 12 is used by T-Mobile, but if AT&T is using this band in certain areas, that could possibly be part of the explanation of why we're having this issue.
Thanks @svnyster!
I also don't think that switching between LTE and WCDMA is acceptable.
But what confuses me is that we have 2 Z3s and only one of them has this problem...
Any idea if unlocking all bands as suggested here would help?

Thanks again.
Pretty sure it has something to do with how AT&T recognizes your IMEI. Check your account and see what icon shows for both devices. If they are different, that's the culprit. I can't get calls and messages with LTE enabled on my Z3. Fine with 3G. My solution was to leave LTE off until I needed it to stream outside of Wi-Fi. AT&T recognizes my IMEI as a flip phone. I have a HTC M9 as well, unbranded edition, and AT&T recognizes the IMEI as a M9 and calls and messages come through immediately even though LTE is switched on.
i've resorted to leaving LTE off and using the H+, which someone explained is sort of like 3.5G but not quite 4G. At times I'll turn LTE on when I want to watch a video and am unable to connect to wi-fi. Sometimes I'll forget to turn LTE off, and find out later friends were trying to reach me but couldn't. As a result, for me, leaving it off is better (so I can be reached for clients or emergencies).
Still, I realize this is unacceptable, but AT&T does not support this phone (or sell it), so at the end of the day, it's my problem for wanting this phone in the first place. Don't get me wrong, I still like it a lot, but this issue and others are becoming a headache that Sony and AT&T could've gotten right from the get go.
Also, I did upgrade the Z3 to Lollipop. I've noticed the battery draining a bit quicker. Instead of having ~50% by end of day, I'm not at 25% levels. Not quite dead, but I still feel the urge to charge mid day when before I didn't have that urge.
Still, I like being able to move (some of) my apps now to the SD card, freeing up the barely 16 GBs on the phone.
Well back in 2014 I purchased the htc one m8 from Verizon which was a huge mistake because the bill was huge aswell. I then left Verizon after about half a year and went to metropcs and purchased an lg. Me being a noob I didn't know that you could unlock phones for a different carrier. So for the longest time I've just been using the m8 as a really nice Ipod. So just a few weeks ago I purchased sunshine and unlocked and s off my m8. I did research and found I needed apn settings and I found the correct settings I needed for my phone. After that I called metro pcs and they tied the device to my account with the imei and the SIM card number, over the phone. It worked out dand, I could see the word metropcs at the top and I could call my friends and my parents, I could text and send picture message. It even said I had 4g lte at the top. But here's the problem. About 4 times a day I will lose all service, and to make it come back on I have to attempt to make a call and as soon as I make the call it drops and says call lost. And then give it about 5 mins and I have my service back and I get all my messages that I would have gotten before all at once. Unless I try to make that call I won't have any service. This happens about 4 or 5 times a day and it's really annoying. I need help on how to fix this. Would I need to flash a custom rom like viper rom instead of this Verizon crap? I'm running android version 5.0.1 and I am unlocked and s off.
Try a different ROM like viper and see if it solves it?
