Weird phone reception/signal problem - T-Mobile Samsung Galaxy S II SGH-T989

I have this weird reception problem. Every once in a while, my phone would enter this weird state. It looks normal as I see my phone has reception. However, people would complain that they try calling or texting me and I would receive nothing. During this same state, if I try calling others with my phone, the phone call application would freeze and no outgoing calls can be made. Also if I were to send a text, I would see a "sending" message and I know for sure the text won't be sent. The only fix is to reboot the phone to get proper reception and I would be able to receive incoming signal and make outgoing calls/texts. Is there a fix or explanation for this problem?
This problem existed on my phone for a while, for stock, AOKP (all stables) and CM (10.1 stable). I don't know if its a radio issue as I tried different radios.

I'm having a similar issue where I randomly can't send or receive calls even though it shows that the signal is just fine. A reboot fixes it.
At first I thought that it was the latest update to the ROM (Slim 7.5 weekly) and so I reverted back to 7 Official. It then happened again so I tried out the Carbon ROM...and it happened again so I went back to Slim but changed radios...and it just happened again so I'm trying a different kernel but I'm doubtful as they've had different kernels anyhow.
My guess is that it either has to do with hercules and 4.2.2 or just whatever commonalities which exist between the various non-TouchWiz ROMS. (if it keeps up though I'm going back to Embryo as it's TW-based and never had this problem)
Oh well, wish I could've offered a solution instead of the above but hopefully someone smart will come along and help.:laugh:

Where are you located and are you on T-Mobile? It could be tower work in your areas. I experience similar situations when they did the refarm and again during the LTE upgrades. Either way if you report signal problems they can have the towers checked where you are.

It could be the work to tweak and expand the LTE in Houston. I know on my phone I get sending errors when I don't delete message threads that are huge. I'm talking about 1000+ txt to the same person with pictures etc. It's just more memory that the phone uses up to display all of that information. You could try deleting some old messages, after backing up anything you want to keep, and see if that helps.

I'm OCD about deleting messages but thank you for the tip.
There are two others in my household on my family plan who aren't experiencing the issues but they are both on completely stock ROMs.

if still having connectivity issues try this -Download terminal emulator and type the following command (or copy and paste)
cat /sys/devices/platform/msm_rpm/fw_version
If your output is 2.0.67419 then you don't need to Odin anything...if it isn't...then you need to update your firmware via Odin. 4.1.2 stock

I am in houston and I am experiencing the same problem. I think it could be related to the tower work.

Here is usually what happened to me. I got into an area where there is low or no service, I tried to send a MMS and it would just stuck at Sending. Once I got back into the full bar area, the MMS is still stuck even though I can send text and get online. I have to delete the MMS, reboot and then I can send MMS fine. I don't make calls that often so I don't know if I can make a call when this happened (I am on a $30/mo walmart plan).
So it could be something in 4.2.2 and got hang up when there is no signal and never timeout so you would lose that functionally until you reboot. Who knows? I can't go back to 4.1.2 ROMs tho so I just reboot...

It's definitely nice to hear that it is happening to others as I've been tearing my hair out trying to figure out which component was messing up (ROM, radio, or kernel). I'd much rather it be them (T-Mobile) than me.
I went back to Embryo, which is TW-based and 4.1.2, just to give it one last go in case it is something with 4.2.2 but if it happens again I'll be back on either Slim or Carbon.
@fsured I sent you a PM back but it didn't look like it sent. Either way thank you for your help as well as everyone else.:highfive:

Issue with GS3

Hi everyone. This is my first time posting on here, so here we go:
I am basically having issues making phone calls and sending/receiving text messages. Now I have talked to Sprint and they troubleshooted the issue with me and would get it to work temporarily. Then it would go back the original issue again. They said that it was not a tower issue. Also, my phone is rooted and running a custom rom. Issues seemed to occur a week or so after I flashed JB based rom by Phantom. Not saying that's the issue, but I figured I would throw that in there. I have also attached a screenshot of my about phone. Since then, I have flashed the original rooted rom that I have on my phone. Maybe you guys can suggest a few things. I have also tried the ##72786#. and that does not fix the problem. At one point, it would work temporarily.
Thanks in advance.
Are you in any part of the US effected by hurricane Sandy?
Ever since hurricane I don't receive calls at my house but go less then a mile away works just fine.
I switched on over to roam on VeriZon network with roam control and everything works.
I got told all towers are working in my area. I even flashed back to 100% stock unrooted.
I had Sprint note in my account I was having issues and depending on how long it continues I'll be getting a credit to my bill.

[Q] Text messages and calls not being received

I've been having a problem with receiving texts sometimes and I recently noticed that it happens with call apparently. The issue is that I'm texting people back and forth and then all of a sudden I wont receive messages for a long time (couple hours). At some point, someone's text message will push through all of the other ones all at the same time. Sometimes when I assume i'm having this issue, I will send a text to myself and it will push the other ones through as well. Recently though I was made aware that during this "outage", I also was not able to receive phone calls at all. The signal is strong at all times (3-4 bars). Also happens when I'm home all day and not changing locations when it will suddenly stop getting texts and calls. Does anyone know how to fix this issue? I restarted the phone and changed cell towers with the Airplane mode many times and the issue continues to happen at random times. It is really inconvenient. Suggestions?
Technical details: I use the stock 4.1.1 Rom that comes with AT&T S3. I do have LTE in my area.
And now it has happened 3 days in a row but at different times of day. This is a huge problem for me as I use my phone a lot. Any help would be appreciated
You still have your IMEI number via settings -> about phone -> status?

That's weird. Re-seat your SIM card, if that doesn't do anything then take a trip to your nearest AT&T store/dealer and have them swap out your SIM card and see if it still occurs after that.
I had a similar problem a while back and it happened to be a network problem with my carrier. Gave them a call and all is fine now.

It happend to me too. I went to att store and get new sim. No problem for last 15-20 days. Looks like i got stronger signal too.
Just to give anyone interested in this an update:
I went to the AT&T store today and told them my issue so they told me to go to the nearest AT&T device support center (which was really far away). People over there told me they heard about this issue many times over the past couple of months. The guy working there had a S3 and said he has the same problem. They received an email from the higher-ups this morning specifically talking about this random outage thing I have and that they are currently working on it. They were told to not exchange phones or sim cards because of this since it wont help. The issue involves a combination of Network and Jelly Bean software problems and happens on all new LTE devices that have Jelly Bean from AT&T. They told me to check periodically if there is a solution.
I guess I just gotta wait. Unless someone recommends a ROM that is not based on the latest AT&T jelly bean?
Bumping it up, both me and my wife have had this happen. From what im read its a pretty widespread deal.
Anyone know of a work around at least until they fix it?
Keep us updated
Same problem here - switched from Verizon to AT&T last month and started noticing this problem a few weeks ago. Back then a Google search didn't find much on it, but this thread looks promising.
Just to add my two cents: I'm on a rooted S3 with task650's AOKP (4.2.1) build 12.23.2012 (link). Made sure to flash the modem for my phone (I747UCLI5 from here). Problem: phone randomly won't receive calls or texts. Sometimes calling someone will fix it.
I read somewhere that on AT&T, calls and texts are received over 3G and sometimes phones have difficulty switching from 4G. Anyone know if this is true?
Do a full wipe /system, /data, /cache, /dalvik cache. And your problems should be gone 9 times out of 10 that's usually everybodys problem

I started a thread on this also and just yesterday received some info from AT&T tech.
http://forum.xda-developers.com/showthread.php?t=2123974
guys,
it is an ATT issue,
here is a temp solution for a fix:
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect
please see, post, comment here:

[Q] Virgin Mobile HTC One V [CDMA] cannot make calls or text reflashed RUU

Hi, so I decided to root/unlock my phone to see if I could fix my cell signal problem, it just randomly started to drop signal every time I made a call and I could not send 100% of my texts and would receive a text once in a blue moon. My 3g for data works fine... I changed roms, still couldn't acquire a signal other than data and the same issue would happen after flashing to different ROMs.
So I reflashed RUU to revert back to stock and I still cannot make a call or send a text. What am I doing wrong? I have searched far and wide and lots of stuff, I don't understand about radio files but maybe those would help? I need some pretty noob proof advice/guides to be honest as I've been having trouble with all of this, and I like my phone, so it'd be nice if I could make calls and text again.

Toro Network Drops, 4.2.2 and 4.3

Hey guys - my VZW Gnex (it's a refurb to replace my old one with a bad screen) has been having excessive network dropouts lately. When I boot the phone, it doesn't acquire signal for over a minute, when I place a call I lose signal afterwards, and data drops out randomly. The device will say it's connected (blue bars), although I cannot use the internet. Also, it'll randomly loose cellular connectivity, although indicate that it has signal. I'll go to send a text and it'll immediately have send errors, and I am unable to make or receive calls, even though it shows I have signal. To fix, a reboot is always necessary. This has happened on 4.3 (crDroid) and 4.2.2 (CM 10.1.3 stable). It has happened across all the different radios, 4.0.4 and up, and across several different kernels. Does anyone have suggestions, the phone isn't really usable if people can't get in touch and I'm unaware that they can't.
EDIT: When I go into the phone info menu *#*#4636*#*# when the radio has no data, it says preferred network is "unknown." If I change it, the setting immediately goes back to unknown.
U might need to go through the insurance and get another one.

This is a known issue with 4.3 ROMs. I'm not sure about 4.2.2. It looks like CM 10.2 may have a fix for it in the next nightly. One known fix is to edit build.prop to include
ro.telepohny.default_cdma_sub=0
Thank has worked for me.

Can't Send SMS; Can Receive SMS/MMS & Send MMS

Hey guys,
I think I've reached the point where it's time to call in the cavalry and see if anyone around here is having the same issue; there appears to be a plague going around on the Verizon network, specifically in the Pennsylvania area, preventing people from sending SMS, but still receiving fine (and 4G works fine too, for the record). MMS still sends / receives fine, but I'm unable to send SMS. There are tricks to allowing a single SMS message to go through which involves toggling Airplane mode on / off every. Single. Time. People have also had success with turning 4G off completely, using the CDMA band after a reboot at which point they can send *several*, but still end up with the same issue.
The only solution I've read about that FIXED it is by reverting back to complete stock from VZW. Performing factory resets, using other ROMs, etc etc...doesn't work. I'd REALLY rather not do this and, frankly, would rather use 3G / toggle Airplane mode for texts than use Sense and get off of my ROM (http://forum.xda-developers.com/showthread.php?t=2560831).
People from other device forums on XDA are having the same problem; the ones I've seen that are active discussions are the Samsung Galaxy S III & IV. They're mostly CM ROMs *as well as* AOSP ROMs in general.
http://forum.xda-developers.com/showthread.php?t=2532414
http://forum.xda-developers.com/showthread.php?t=2658572
SIM card replacements are a no-go, and the recorded instances seem to be in the 717 / 570 area codes, mostly. Now I DO know that VZW released an OTA update for the One recently, and I'm relatively confident that would fix the issue, but I've no idea why. I'm thinking perhaps they dispatched new radios? I looked around a bit and couldn't find any flashable zips of radios extracted from the latest OTA, that's the next step I'll be trying once that download finishes.
So is anyone else having this issue? Any word on fixes?
The newest firmware from the latest OTA can be found in the 2nd post in this thread: http://forum.xda-developers.com/showthread.php?t=2485319
If you've already flashed the latest firmware then I'm not sure what to tell you... maybe ask your favorite rom developer to take a look at the latest OTA in regards to this issue?
If it has the stock rom and OTA update why not take it to the store and let them look at it. Something might be wrong with your account.

Those area codes for all phones on aosp roms are not working right now. Since 2/20/14. Has nothing to do with HTC or their firmware. I'ts a bizarre Verizon 4G issue. I am in the 717 area code with a Note 2 with the issue. I have seen others with S4 and S3. Verizon is aware of the issue and is working with another XDA member to fix it. To date it's not resolved.

I can't believe Verizon has let this issue go on for so long, but given that it seems to only be relevant to those of us with AOSP ROM's, I guess it makes sense. At least I'm still able to send texts, if not only through a silly process of toggling airplane mode on / off. Hopefully it gets resolved soon...

Whoa, that's weird. I really thought it was isolated to the 717 area code. It's getting pretty crazy...I've been dealing with this for a few weeks now and my patience is running thin. Unfortunately it's not like we can just report this to VZW because all anyone would tell us to do is "restore to factory", which simply isn't a solution.

Yup, I thought so too. Just cropped up between 10a and 11a PDT. Like you said MMS is fine, simply affects SMS. And yes, restoring stock is simply not an option. Going to TMobile, however, is totally an option that I'm considering more and more often......
EDIT: AND SMS began sending properly (without workaround) for me around 8p PDT last night, just tested and still ok. RESOLVED!
EDIT EDIT: Issue now persists....sadface =[
