The wife and I have Atrix HD phones that we bought used but in great condition a couple months ago. We purchased the Straight Talk at&t compatible micro sim kits from walmart.com and set up our service. We previously had Samsung Captivates also on Straight Talk and they worked flawlessly. I put in my APN settings and I get data and MMS perfectly but occasionally I get a red triangle where my signal bars should be and my phone says "Emergency Calls Only" and I will wait 30 seconds or so and my signal returns. There is no steady decline in signal that leads up to this. It goes from like 4 bars to a red triangle with a cross inside it.
I live in a fair sized town and have always had 3 or more bars of at&t service with phones in the past so I do not think its an issue with poor coverage. I am attaching pictures of my APN settings.
Any help would be appreciated.

I'm having the exact same issue since switching to to the 4G LTE micro sim. It only seems to happen on mine when I'm connected to Wifi though. I get the red triangle intermittently. This never happened to me until I went from the old sim to the new one. Can't find anything on it yet.
same thing
The same thing is happening to me here as well but using a Net10 LTE sim card (same as straight talk basically). I notice it the most after I complete a phone call. It takes a minute or two to regain service again. This is really annoying. Would like to see a solution to this problem.
So I worked with Straight Talk support for about 5 days, back and forth, bounced to several reps throughout and nothing substantial has come of it. It seems a little better after they made "adjustments" to my account as they put it, but I still get disconnected from mobile data when on wifi.
Don't get me wrong, their support people were very responsive and seemed to genuinely want to help me, but in the end they said "your ticket has been open for more than 24 hours so it has been closed. If you continue to have issues please open a new ticket." Anyone else have any luck on this?
I also was having this problem found that if you edit existing att apn (phone needs to be rooted)with sqlite editor it seems to work fine.
tether also works fine this way.I am still not able to get lte to work with straight talk even with new sim.
Just to follow up. As usual, it seems with ST support, one rep tells me they have some things they can try once I call back on another line and then I get a new rep who says nothing can be done until 10 people complain about the exact same issue I'm having. I'm assured this is an isolated incident...
I went ahead and purchased a new SIM card (looks different than the first LTE card I had) in case I had a faulty SIM. Worked flawlessly for a day and now it's back to the same issue of cutting out completely throughout the day.
same problem here on wifi get red triangle (especially after phone call).
More since i switched from 4g sim card to lte sim noticed that data disconnect from time to time like make impossible to watch video flawlessly...
with old 4g was yes only 4g but never loss a bite....could watch anything also streaming tv.....now it is impossible.....
the end of the month going to switch to old sim and see if the problem is in the new sim cards they tried may be to limit access or is in the new service doesn't matter what sim card you possess..
we'll see...

Switching to my old sim was my first thought to. However when I tried it didn't work. I called ST and they informed me that once you switch sims, the old one can never be reactivated. On top of that they don't offer the non LTE sims anymore. Such a pain. Hope you have better luck though.

Some one could correct me if I'm wrong here but I'm pretty sure this is a result of ROMS using a 4.4 rom. Modem crashes. If you want to test it run a Stock ROM... If you are already using a completely stock ROM then Idk what to tell you. But same thing happens to me using any version besides stock. And yes only when on WiFi

Then unlock your bootloader and try flashing different radios from the different stock fastboots we have. Depending on the fastboot I can have next to none or almost full in my bedroom. For me, ATT JB is in the middle, JB Mex Retail is the best, Bell ICS is the worst. ATT ICS was about the same as ATT JB.

For the time being, I just switched to Aio and so far so good with LTE coverage and no disconnecting issues. If they return I'll try different radios as you suggested.
So I've been with Aio for about a week now and everything is working great (knock on wood). I've had 2 mobile data drops at work with Wifi turned on, but they only lasted for a second and I do have really bad reception here inside the building. Outside of that no issues at all so far. I'll update if anything changes.
A. Introduction: I had the HTC Desire C working smooth and fine. Then one fine day, I realized that the microphone is not working properly, the person at the other side of phone call would not be able to listen to me unless I'd literally shout over phone. So I gave the phone to the HTC service center because it was under warranty. They changed some parts and handed back the phone to me. But the problem was still there. I again submitted my phone. They changed the same parts again and now the mic was working classic, phone was working smooth.
B. Twist in the scene: Just after few days, I was on my way to home after some work and I noticed that phone had a cross (x) against the signal and when I pulled down the notification thing, it said NO SERVICE. This used to happen a lot of times from then onward. Switching to Flight Mode and then reverting back (OR a restart OR a sim pullout and insert again) would sometimes fix the issue, but only temporarily. Sometimes after reboot, it would say NO SIM CARD, sometimes NO SERVICE and sometimes proper functioning with 2-3 bars.
C. Attempts from my end: I thought that they have messed the sim card slot while assembling my phone back and it is a hardware issue. But I was finding it hard to believe. I tried switching to GSM ONLY, then it would show full bars, but again only temporarily -- later NO SERVICE again.
The same SIM card in other phones (standard Nokia b&w phones aka hammers) shows full bars. And I have tried 3+ sim cards in the HTC, but all say NO SERVICE after sometime, maybe due to some activity (connecting internet) or just randomly on its wish.
I studied about radios(modems/baseband) and found that they are drivers and they also decide when and how to switch between 2G and 3G network etc.
D. Other Information and Background: Many times, when there is NO SERVICE error, when I check the Signal Strength it says -83dBm 15asu, so that is pretty hard to digest. The other times it says 0dBm 99asu, which should be obvious for a NO SERVICE error.
With point number E.2. in this post I have unlocked the bootloader and rooted my phone, installed CWM recovery, took a backup.
E. Options that are/aren't available from my perspective and my doubts:
1. Warranty period is over now, and I do not want to take my phone to the service center.
2. Can flashing a custom rom and radio fix this issue? If yes, direct me to some reliable ROMs for the same. CM10 build#3 (from here) didn't boot.
3. I have a Linux laptop, so options strictly based on Windows PC will not apply.
Has anyone faced similar issue? I found many pages with similar issue, but nowhere was the exact solution/troubleshoot mentioned.
I did have a problem with sim cards. What I tried doing is borrowing a friends sim card to see if it works on my phone. To my relief it worked and meant that my current one just died. So I went to one of the offices of my Phone plan providers and just changed it and it worked. If you can try that and give back results, it would be awesome.
Depending on the age of your SIM card can give those errors but as you stated you tried other SIMS and same occurred so my guess is it's either Hardware or Baseband Software, unless there's a Baseband update or simply reflash same Baseband, if it still persists I'd more suspect Hardware.

I, myself have a lot of sim cards to check this and I have already tried other sim cards. Some cards are not even recognized. Some are being recognized but it says NO SERVICE after sometime. Switching to Flight mode and back or restarting the phone or Going in Testing Mode > turning off radio > and turning it on again, sometimes solves the issue but only temporarily.

Probably. And that's why I installed mini CM10 and flashed the radio with the latest HTC Desire Radio (for CM), but it still says NO SERVICE and the same baseband version as it was saying with the stock ROM. :/
Even though the signal strength is -63dBm 25asu
Can you call or something if it is showing signal strength?

No, I wasn't able to call. And when I would search for a network it would say "Error while searching for networks"
I'm more likely to suspect the actual SIM card holder hardware and not the SIM Card itself or the Baseband (No errors reflashing and other SIM's no different than your own), the fact it's showing signal strengths but you're not getting onto the network suggests RADIO hardware is most likely working along with software but a hardware failure could just be 1 connection to the SIM
Q. Are all other SIM's working in other phones and does your SIM work in another phone?
If so I'd suspect the SIM Slot onwards.
Q. may or may not apply but possibly relevant, does Bluetooth and Wi-Fi still work?

Answer #1: Yes
Answer #2: Yes
Q. I still don't get that when I have flashed the radio, how is it still saying the same baseband version? Doesn't flashing a new radio change it?
Recent UPDATE: Somehow, the phone is behaving well... (always 3 bars or full 4 bars), after the mini CM flash and NOPE 750 flash. Initially it was NO SIM CARD or NO SERVICE but multiple reboots and pulling out and reinserting the sim card have made it this far. Let's see if this good behavior persists.
UPDATE: Back to the same state of disconnecting/No Service/No Sim Card
I still suspect the SIM slot as you could have disturbed what's known as a 'dry joint' essentially made it make contact until it disconnects again even with just a change in any kind of pressure (placing the cover on or placing it on a table).
Then again it could be down to ROM and Kernel, I wouldn't totally rule it out without going back to stock ROM and Kernel and seeing any change

UPDATE: The network seems quite reliable when I am on GSM only (2G only). That again indicates that somehow the problem lies in only the radio driver.
Any ideas?
Same Problem
I am facing exactly same problem on my HTC Desire C. Did lot of hard reset problem reappears after couple of days. got my phone reinstall OS at HTC service centre problem reappeared after a week.
Same sim is working fine in other phone, even got new sim still same problem.
Am confused if its hardware or software issue, problem comes only when phone is in GSM only mode, works fine on WCDMA only or AUTO mode.
But in WCDMA only since network is not good signals are low and in AUTO mode when signals are low it switches to GSM and if at that particular moment there is problem then NO SIGNALS.
Update, Phone fine. Help with the settings!
I checked a lot of sim cards and found that my phone is perfect! There is no hardware issue.
So I am presenting the present scenario. Please help!
I have 2 phones: HTC Desire C and a Nokia B&W aka hammer.
1. TATA DOCOMO sim card work fine on both phones.
2. AirTel sim card works fine in Nokia but HTC says "No Sim Card" regardless of the numerous attempts.
3. Reliance sim card (brand new, bought today) works fine in Nokia but HTC says "No Sim Card".
4. A friend's Reliance sim card was working fine in HTC.
If any Indian friend might help, then it would be great as this issue is more local specific I guess. Or any user who might have faced similar issue and then found a fix please help.
You tried Vodafone?

Not yet.
And believe it or not, but the AirTel sim that I mentioned in my last post was working once I washed it with some alcohol. So it might indicate that the sim was old and dirty maybe.
But what about the new Reliance sim, I just bought it today and it works in Nokia. I'd have switched to Vodafone but I can't afford its high 3G plan rates as I have to maintain an MTS MBlaze for laptop as well.
And the thing that friend's Reliance sim works fine in my phone is troubling me even more.
Ok, My old SGS3 finally gave up the ghost and I purchased a Z3c. I trimmed the SIM card from my SGS3 to fit the Z3c, booted up setup the phone and am on LTE (At&T) able to make voice calls, send and receive sms, check voicemail etc...
I noticed when I log into my ATT account page online it shows a generic phone picture now instead of the SGS3 picture it used to. What benefit do I gain from calling in my new IMEI number? I ask because for the moment everything appears to be working great... and if there is no strong negative to not updating my IMEI I was wondering why do it (as I assume they may attempt to hit me with an upgrade fee or I have read a few threads on other sites about how when they provided the new IMEI suddenly LTE or other service issues cropped up that weren't there when using the old IMEI...)
Thanks for any responses that might be helpful in allowing me to understand why I should update it or why it may or may not be important (pro's and con's)
At&t doesn't care about the IMEI change, if things are working well, including LTE, then just leave it as is.

Thanks, sounds simple enough and it was sort of what I thought! Now on to more important things...like figuring out what case to get that works with my DK48 charging dock
If you did not get ur phone from them there's no need to do it. I think it's only required on iPhones because Apple always has a way to make activating everything harder.
I called AT&T and went to 1 of their authorize offices and got a LTE sim card and everything works great. If you already have a IPhone that sim card has LTE enable. So don't worry about it...
I have lurked so much around XDA and still I have no solution
I own a Moto X XT1053 on Movistar (Mexico)
Everything was working fine until I got my SIM card replaced. Now Voice and SMS don't seem to function but Data from my carrier works fine.
When I try to dial I get a "Mobile network not available"
I have done "fastboot oem config carrier (all possible options) No luck.
I have switched from 4G to Edge since that seems to be the solution for many but that didn't work for me.
Yes I have searched for networks and selected "Choose Automatically" No luck.
I have flashed back to stock firmware using T-Mobile's firmware (which has always been my solution and everything worked flawlessly) but now that doesn't work. I've actually not a fan of custom roms I only do stock and xposed the [email protected]#$! out of it but even a clean stock doesn't seem to fix it.
I even went to Movistar and they believe its my phone since they tested my sim on another phone and voice worked on theirs.
Any thoughts on what could be the solution? Please Help!
Check the APNs?

I think your first statement supersedes your latter statement and everything in between. Just because your new SIM worked properly in another phone doesn't mean it's guaranteed to work in your moto x. Maybe for some reason your moto x is reading the sim as a data only Sim, or maybe it's registering on the network as a data only Sim.
did you cut the Sim to nano or did it come as nano?
Did you try a different SIM in your Moto X?

They did try another Sim on my phone and same, no good. Voice seemed to work on other phones. I personally believe my phone was blacklisted. When I went to get my Sim changed I forgot to mention the account was under my moms name. Now my new Sim is under my name but with the number of another owner (my mom). Which could explain why I get no voice or SMS but data works fine. I am actually on my way to customer service right now.
Well just returned from customer service. No good. Its the phone itself. :/

Have you solved the problem? I'm using Samsung Galaxy S5 and has similar problem... After couple of times of change rom the problem occur... I'm not genius and I have struggle with this problem for more than 2 weeks... See whether we can work this out...
My situation is:
1. Voice: out of service, data: inservice;
2. IMEI: seems normal
3. I tried two SIM card with different ISP, neither work;
4. I also try that two SIM card on my iphone4, both work well.
5. Since my phone is G900F HK version, and I'm currently in UK, so I tried latest UK stock firmware and latest HK stock firmware. Same...
I had do some searching and said that there are few reason that might lead to this problem:
1. IMEI error. Flash rom may damage your partition, if your IMEI is 0046*** or 0000*** something then this is the case;
2. Baseband related. Just flash some wired rom that no capable with your local bands?
3. still looking...
Good luck then...
Same thing
Did you ever solve this? I am having the same problem on my Moto x Pure 2015.
So as of saturday my unlocked TMobile Note 4 stopped working as a phone, and won't let me make calls.
Information:
-Was on Dr. Ketan L3 version of his rom when it stopped working
-Using the N910T on AT&T
-IMEI is fine and not damaged, both numbers match (using *#06#)
-It shows bars, but when I go to make a call "Not Registered On Network"
What I've Done:
-Flashed Stock Firmware via Odin (Autoboot, and F.Time Rest checked)
-Factory Reset after odin flash
-Checked APN
-Set on LTE/WCDMA/GSM
-Searched for Networks, finds them, but when I choose AT&T it takes forever and then finally kicks me out and then in notifications, I get the "Not Registered to Network"
-Did the remove the battery thing, and removed sim
-Went to AT&T and got a new sim, worked for 1hr (sporadically) and then went back to "Not Registered on Network"
-At the store I was on phone with AT&T tech trying to troubleshoot the problem and that is when it was working shortly
-Called T-Mobile and checked to see if they blocked my IMEI number, nope they didn't, couldn't help me out further than that
-AT&T was showing that it was a Note 4 so not having that coming up as a Blackberry issue that some reported, so that's not it
-*#0011# shows service limited, but it is unlocked and everything is fine, the IMEI is good, and all is well but the limited service
-Put it in Airplane mode and woke it back from there after 5+minutes
-cleaned the connectors on the sim (new sim anyways so shouldn't really need them)
I'm running out of options, the only thing I can think of being the problem is that I might have started out using this phone on COD2, and when I flashed a COG2 firmware it didn't like that and so my phone's account settings didn't fully transfer.
Also I was messing around with the bands settings (*#2263#) what should they be on? Automatic, LTE/GSM only, or what?
Settings should be on automatic. One more thing to try is go for a drive with the phone, at least 5 miles from your house, and see if it does this when connected to other towers. I had this same issue years ago and it turned out to be a malfunctioning tower by my house.
If it still does it on other towers, then it may be hardware-related

Thanks, yeah it kicks in randomly for like a minute and then dies, I take it to my parent's house (about 10 miles away) and along the way I get a good signal, but then when I reach their house, back to nothing. I was using it just fine the week prior. I partially blame Dr. Ketan, ever since installing his rom, I had multiple issues. I since uninstalled it and tried going back to stock. Any idea on what a good "safe" band setting is? I have that settings set to automatic, but if there was a good "safe" band that would be great. A common LTE tower. Even when I do connect or get connected, I can't register on that network, my phone won't let me. I've tried that. The bars drop to zero. I damaged my antenna wire (white one) and I just replaced it with a new one I purchased, but the hacked together one seemed to be doing the same quality job as the new one is. It shows the signal, but as soon as you try tying it down to a network it rejects it. I was afraid that when I flashed the stock image via odin it removed the unlock, but it was still there. I just hate that now I have a $500 pda, when it was a phone and now i'm relegated to using a f*ing flip phone.
i think your antenna cable is damaged. the only way to know that is be close to a tower, and see if your work or not.
bought and replaced with new ones, I get full bars, in my bedroom, but apparently they're tied to Tmobile since when I try to register it to AT&T they magically disappear, but when I close the app, they come back at the same strength level. I can't register them to Tmo since the sim. Yet my phone is telling me it's unlocked (*#0011#), IMEI = PASS, 1;
I think the prob is due to the different frequencies.
Your baseband would not be tied to a rom(ie Dr Ketan) Unless that rom contains Modem.bin
Your apn needs to be att if that's your Sim obviously.
International version has a different chipset. .. I know it's not your case. .
But it's open to any Sim. ..
I can say this.. I have a N2 unlocked (tmob) I run an Att Sim it works but the sig is really spotty... COD6/ COG2 may not be lining up frequency wise with your att Sim. ..
Try rolling your baseband back even further. .

Any clue on to what i should use for best results? Like 850/1900 or 900/2100? What is a good LTE band? Where could I find a map of LTE bands used by carriers, I know how to get to that secret menu and manually change it to see if I get better results?

Well I would think automatic is out for sure.. the other prob would be after reboot the chipset will search for the default.. but I could be wrong.
I do not know what the numbers would be for band identification.
You may get lucky when calling Att and ask for someone in a higher tier. To give you some numbers for frequincies .
But you have ruled out hardware correct??
By putting a tmob Sim in????
Cuz I know you posted you did antenna work..
And I do know you said you get bars then it fades..
The fact it fades and doesn't lock into even a G band for example. Just leads me to believe the apn can't lock down based on the frequincie and the built in lte chipset...
It would be nice to just flash an att modem wouldn't it?? But don't even think about it.. lol you'll soft brick..
I wish I had a better solid answer you. You may just start testing those different bands and see if you get closer to a lock.

My Tricked Out N910P
But what could have happened that made it crap out like that since it was working just fine beforehand for 2 solid months on custom roms and what not? That's the frustrating part, I've been flashing different modems on my phone, but none have been successful. Apparently there are 3 different N910T, how do you know which ones to play with? I flashed N910T(3) bands, that failed, I did try N910A, obviously failed. Then I lost my IMEI number, got terrified, tried reflashing EFS in TWRP, nothing. Then reflashed COG2 bands, it came back. Is there an app on the Playstore that would definitively tell you if your network chip is damaged? I wouldn't know what to look for.
Have you taken apart the Note 4, what are all those contact points, are those antenna things? One of those were damaged, they're like folded metal spring boards with gold tips (same kind of thing that is used to install a qi receiver, same design). I took my tweezer and fixed it, but could that be the culprit, since on the surface, it seems like the network is fine. Works really well in WCDMA, but not much else. I was able to make calls using GSM only, but my signal was 1 bar and the audio quality was questionable, so I left it alone for 10 minutes on that hoping it would force a reconnect. This is frustrating, since I wasted $500 on this phone and not having it work after two months means now I'm back to a featureless phone.
Thanks for your advice thus far. Flashing different modems hasn't been working out well, I just wished I could remember what baseband version the guy had the phone on when I first got it? I thought it was COD6, it was definitely on Lollipop, but if it's a 910T(2) would I know, how would I know?
How do you flash NON_HLOS and modem.bin at the same time in Odin? I know Modem does bands, but what does Non-Hlos do? I thought i read LTE, so if those aren't in sync and on two different versions could that be the issue? I extracted them from the full TAR firmware files.

I flashed N910T(3) bands, that failed, I did try N910A, obviously failed. Then I lost my IMEI number, got terrified, tried reflashing EFS in TWRP, nothing. Then reflashed COG2 bands, it came back. Is there an app on the Playstore that would definitively tell you if your network chip is damaged? I wouldn't know what to look for.
Have you taken apart the Note 4, what are all those contact points, are those antenna things? One of those were damaged, they're like folded metal spring boards with gold tips (same kind of thing that is used to install a qi receiver, same design). I took my tweezer and fixed it, but could that be the culprit, since on the surface, it seems like the network is fine. Works really well in WCDMA, but not much else. I was able to make calls using GSM only, but my signal was 1 bar and the audio quality was questionable, so I left it alone for 10 minutes on that hoping it would force a reconnect. This is frustrating, since I wasted $500 on this phone and not having it work after two months means now I'm back to a featureless phone.
Thanks for your advice thus far. Flashing different modems hasn't been working out well, I just wished I could remember what baseband version the guy had the phone on when I first got it? I thought it was COD6, it was definitely on Lollipop, but if it's a 910T(2) would I know, how would I know?
How do you flash NON_HLOS and modem.bin at the same time in Odin? I know Modem does bands, but what does Non-Hlos do? I thought i read LTE, so if those aren't in sync and on two different versions could that be the issue? I extracted them from the full TAR firmware files.

Heres
A simple method for COD6
And try odin 3.07
I need to think about this some more and get back to you...
This is a partial firmware.. it consists of the modem and bootloader COD6.
Also to rule out damage if you can get a T Mobile Sim put it in the device and see if it locks down a signal....

That was my next move, not having any real income but disability and little coming from that, I thought that was the next logical step too. I'll get a tmobile to go sim and try it see if it can't lock on to that, and see if that doesn't set it on the right path. Have you heard of other people having COG2 issues on AT&T unlocked? Maybe that was the problem, something there broke the connection. I don't know, but whatever it is, I can't thank you enough, you've at least given me more options to try that I couldn't think of on my own. I'll try that file.

You are the first of this kind that I'm aware of.. in regards to this issue..
Make sure you read the detail in if your device bootloops, to reboot recovery and flash the Rom.. if you want flash the Rom in the op that I've linked you to.
Wipe sys/dal/cach/data..
And flash it can't hurt.. [emoji16]
I really hope a Tmob Sim and or COD6 gives you results...and good ones at that.. [emoji2] [emoji106]

Got the sim card, $65 for that crap, and it didn't work. Called T Mobile customer service, explained my situation and how I was calling on another phone on another carrier and they insisted on calling me back on the broken not working phone. I guess I'm just screwed, and lost $500, which like I said, I can't afford to have. It's just so frustrating. I also tried the COD6 partial firmware, and nothing there also. I'll try t-mobile again. The only and last option I have, if possible, is to try to relock my phone and re-unlock it since there isn't any real way to tell if my GSM is damaged. I think my unlocked status got damaged when my phone upgraded to COG2, and since it's in that weird limbo state I can't use my phone. Do you know how to relock it?
Edit: When I look at my IMEI Number through *#06# it shows that the last two digits (independent of the actual IMEI number, since that matches everywhere) to the right of the "/" as 14, yet through "about device" it shows my imei version as 10. I assume that the 14 in the "06" screen is the version it's reading off the phone, could that be causing the issue? How would you even fix that? I don't know. but thanks again, you've been helpful.
