Calls going directly to voicemail

I've been having an issue where my incoming calls are sent directly to my voicemail. It happens about 70% of the time, and its incredibly frustrating. I went into a Sprint store and they performed a firmware update, and it seemed to fix the problem for a couple weeks, but its back again. I've tried searching but havent been able to find anything.
A Sprint employee told me that Android phones require a couple seconds to "completely" hang up. Not sure that the issue though. My area is 1x, phone is in Hybrid Mode and the feature to automatically send to voicemail is disabled.
Any ideas? Anyone else having this problem?

I am having the exact same issue; and I've noticed it has gotten worse over the last week. I'm not in a 3g area, and I notice it happens more frequently if I've been surfing the web or using data.

do you guys/gals experience this in one particular area? meaning it o only happens at home? seems like your phones might not be getting service and the calls get sent straight to voicemail.

Since CDMA cannot handle voice and data at the same time you may notice calls going straight to voice mail if you've been browsing or using data. The call may never come through if you happen to be using data at the exact time a voice call is coming through...

check settings/call settings and make sure DDTM mode is not checked

mine seems to be more or less random. I usually have solid signal; and I've had people tell me they called four or five times and the first ones went right to voicemail and then one randomly gets through. In these cases I KNOW I haven't moved my phone...

This is true, however, the device is smart enough to know when to cut the data connection if a call is coming in.
I got a replacement device yesterday, seems to be working fine now.

This is exactly what I was experiencing, also in solid 1x coverage. I would recommend going to a Sprint store and asking for a replacement. They replaced mine with no questions asked when the Rep tried to place a call to my phone unsuccessfully in the store.

Still have sim error after update who else?

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?

reprovisioning does not work, don't waste your time

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.

Lost Signal (Verizon)

Earlier today I was attempting to switch to Textra as my new texting app, but had issues getting MMS to come through, so I followed some steps to attempt and change the APN for my phone. Somewhere while doing this and rebooting a few times I lost signal on my phone and couldn't get it back. I flashed a new ROM (viper) and the signal came back for a while, but then the phone rebooted to finish an update and I lost it again (so I'm pretty sure its not my sim card).
I am able to get the signal to come back for about 3 seconds every time I toggle airplane mode. I'm not sure why this is, maybe its not actually connecting? Any ideas what to do to fix this issue? I tried a safe reboot through Viper but still had the issue so it doesn't seem to be any apps interfering or anything like that.

Found a bit of a workaround that does something...
Went into the hidden phone info settings and set preferred network to LTE/CDMA (or LTE only, both worked). This allows me to use LTE for loading websites and apps and stuff but texting and calling do not work.

Same issue. Seems to be the same problem that's been under discussion for months. Verizon just immediately blames it on the device (despite the fact that they can't explain why it worked fine a week ago or why I still get data). My solution is to just switch to t-mobile. I'll be saving myself $30-40, getting unlimited (instead of 6GB) and a network that works fully. Just waiting for my sims to arrive. I know it's not really a solution but Verizon seems to be completely unwilling to even acknowledge the issue let alone fix it. Problems seems to exist on other BYOD phones as well so it's debatable whether they're just incompetent or actively blocking devices they don't sell.

FYI, the tldr of that thread is that no fix or root cause is known, but it's happening to a seemingly significant number of people. Pretty much everyone gave up trying to use the U11 on Verizon after having the issue by either switching phones or carriers. With one or two getting a replacement U11 and claiming that it work, for now at least. The issue seems isolated to only Verizon.

[F.Y.I.] Having trouble activating visual voicemail? Try this.

So I'm on MetroPCS and was experiencing an issue I'd like to share. When loading the MetroPCS visual voicemail app, I noticed when it first loads to activate is was taking forever to do so. This finally ended in a notification that was something like, "We're experiencing technical difficulties in activating your phone for visual voicemail. Please try again later". I had a feeling it wasn't actually "technical difficulties" so I started seeking out the issue. In most modern dialers; google, true phone (the one I was using), oneplus dialer, there is a check box for visual voicemail right from within the settings of these phone apps themselves. It is by default, checked. As long as this option is checked, my MetroPCS voicemail app would not activate. Uncheck it and... Voila! Instantly activated. I am unsure if once activated, that switch can be turned back on, but I really don't mind having to use the official app on my phone. I have heard of issues just like this on other carriers -particularly when a B.Y.O.D. device is involved. This may be helpful to more than just OnePlus users but I'm writing this as an F.Y.I. to maybe help someone with the same issue I had. If I helped you, please hit the thanks button.

Yeah, you can flip the switch as many times as you want and it will switch on and off without issues.

Hi, I have a OnePlus 3 and I'm looking for a new carrier. Switching from Mint, with which visual voicemail never worked, and that was a major pain.
Was wondering whether you could confirm that it has continued to work on MetroPCS through new firmware releases and also if you could let me know what model OnePlus you have? I saw a lot of comments on the OnePlus forums saying that there have been issues with at least the 5T and 6 Oreo builds. I just know I'm going to go in the store and they're going to say yes of course it works with your phone but then it won't...
Thanks for your help!

Certainly. I have a one plus 6 a6003 mirror black with 128gb storage. Everything works perfectly including the newest Oreo update. I have yet to try pie since it's still in beta. Calling over volte and wifi works. As does wifi messaging. I do recommend everyone who's on metro, use TMobile apn's, however. Metro (TMobile) continues to have issues inside buildings in rural areas as most of band 66 and 71 are located in or near cities. But having the ability to be on wifi for calls and texts alleviates the pain. If you're wanting a new device and don't mind the lack of a headphone jack, consider waiting for the 6t. It should have all of what the 6 has plus an in screen fingerprint reader, wireless charging and larger battery. Coming in the next month or so. Good luck!

Hey thanks so much for getting back to me so quickly! I think I MetroPCS is the way to go. T-Mobile is by far the best carrier in my city, and I had Mint (also T-mobile) but the customer support was atrocious and things like visual voicemail that I really liked when I had a Nexus through project fi just didn't work. I'll head down to the store today and sign up.
Thanks again.

Not a problem. I know sometimes people are waiting on a response to take action. Glad I could help. As for metro, comparing to other mvnos: 1. They have actual stores you can go into for help if needed. 2. They are actually owned by TMobile themselves so least likely to go away. 3. Because TMobile owns them, they usually have the best deal you can get. A piece of advice; if you already have a phone and are planning to use the Sim from that phone in your new device, you'll need the IMEI number which is usually on the back or in the battery compartment of the device. It's also under settings>about phone>status>IMEI information. If you have your current phone and activate on metro then later decide to get a one plus 6 or 6t and plan to take your sim out of your current phone for use in your new op6, going into metro to have them do it results in a $10 charge. Instead, call up metro and DO NOT use the automated system. It will disconnect you. Instead talk to an agent and tell them you need to switch phones and are using the old sim. They will do the transfer for free!

Question Calls End Immediately or Can't be Received - And Speakerphone Won't Work

Very frustrated with Unlocked (USA) S22 Ultra. Somewhat frequently but intermittently my phone is unable to make a call. When I try to make the call it just ends immediately - and of note this is in full cellular service (4g or 5G) and also even if WiFi is on and the call is being attempted on WiFi calling. So it's not just a cellular network problem. The problem is reminiscent of back in the day when I would flash a custom ROM and the call features or CSC was messed up.
I believe a similar issue is that often I will get a text from my daughter (who the heck knows how many business calls I missed) - she says that she has tried to call all day and the call just ends immediately and won't ring through to me.
Looks like there are many complaints out there on the internet -- I am looking for a fix hopefully form someone int his community. I wonder if flashing ATT firmware on my unlocked phone would help??
Another problem is that sometimes (definitely intermittently) I am unable to activate the Speakerphone. Pushing the button highlights the Speakerphone indicator BUT the sound is still through the headset - not the speakerphone. Thoughts?

are you on June update? The latest june update seems to have fixed some of the GSM issue so maybe that would resolve your problem.

Never ever had this problem (ATT - locked, 12/512 SD). if nothing else you may want to try to take to ATT for re-provisioning (I assume ATT may be who you are trying to use)

Looks like there are many complaints out there on the internet -- I am looking for a fix hopefully form someone int his community. I wonder if flashing ATT firmware on my unlocked phone would help??
Another problem is that sometimes (definitely intermittently) I am unable to activate the Speakerphone. Pushing the button highlights the Speakerphone indicator BUT the sound is still through the headset - not the speakerphone. Thoughts?

I got the U.S. Unlocked 512/12 Snap Dragon also. No problems on prepaid plan on TMobile. Maybe it time to ditch that Crappy AT&T sucketh Network.

West Virginia explains a lot! I am in South Carolina now but grew up in Pittsburgh so I drive thru West Virginia alot on 79 and not surprised about cell reception.

I've had this happen a few times with an Unlocked version on ATT. I'll try to make a call and it will just immediately end. A reboot fixes it, but if someone was trying to call me I would have no idea.

Have you tried clearing the dialers cache and data?
What about a third party app like googles dialer?

I had the same issue on my s21 ultra and went thru various fixed ( reprovision, changed sim, manufacture reset ..etc). I bought unlocked S22 ultra direct from Samsung and same issue. I have my work # on using physical sim and personal # esim. "when I try to make the call it just ends immediately - and of note this is in full cellular service (4g or 5G).." same issue around 10 times in the last 6 months. It happened on both physical sim and esim. The person who called either number went to voicemail and texting was fine. When I tried to call used either number and it will end right away. when it happened I would reboot and wipe cache partition. I haven't received June update yet and hopefully, that fixes it. I am also unable to send MMS on secondary # but SMS is fine.
