[Q] Lost data connection - Captivate Q&A, Help & Troubleshooting

I have CM 7.1 stable. I had this problem before with stock 2.2 and 2.3
Phone will just lose connection in an area with known good signal - I'm in NYC.
Sometimes my bars and the 3G/H icon go white instead of green, sometimes the 3G/H icon disappears along with the "AT&T" on the lock screen, while I still have 4 bars (although white).
In either situation, I miss calls and texts, and can't dial out, can't dial voicemail.
I'll turn on / off airplane mode which sometimes works, other times I have to reboot.
I returned my first captivate some time ago and got a newer one. I was also given a new SIM card.
Is there any solution to this? Are there any ROMs which are known to address this problem?

I'm not the most Android savvy person, but this sounds like a modem issue. You can refer to this map and pick the model that best suits your area.

Eh, the site / map you suggested recommends the JL3 or JK4 - I am using JL3 so I am a bit doubtful on this as a solution.
Anyone else?

Problem with Orange branded Kaiser

Has anyone else experienced this problem.
Although the phone shows it is connected to the Orange network quite often voice calls to the phone go straight to the voicemail, it seems that the phone is taking so long to process the call that the network assumes it is switched off and then diverts the call to the voicemail. a text then arrives notifying me of a missed call. Any ideas.
Incidentally I put the sim card back in my Artemis and everything worked OK

I too, seem to experience the same issue.. :\
It only seem to occurs after a while that the phone is in "extended sleep mode" (aka press the power key).
Now I'm trying a few things, I've switch the phone to GSM only network to see if THIS might be the issue... but if someone knows anything about this I'd be more than glad to be able to fix the issue
By the way my Kaiser is unbranded, the original HTC one!
You say you get a text re missed call, as opposed to a missed call notification. That would normally mean that the network couldn't see your phone - as normal internal missed calls (ie where you didnt asnwer) wouldn't send a text but would use an internal missed call counter.
So... do you have really weak 3g signal where you are and although the device thinks its connected, it isnt really?
Or is your device faulty...

Well I can say for me that the signal is always allmost full bars.
and I get txt msg saying either I have missed a call or that I have a new voicemail msg (Those are service provided by my carrier) So it's NOT "missed call notification" by WM.
So the network can't see your device when its trying to route a call to it...
Have you tried the device on GSM only? (settings, phone, band, change it from auto to gsm) to see if its a 3g network problem?

Yeah that's what I mentionned earlier, so far it seems to be okay.
But what could cause this? The device switching between the networks?
I've got it as well, but I have to say I have experienced this on the Wizard also, and that's not a 3g phone. Also had it on the Universal, and that's why I used a Tornado for a year as it didn't occur on the smartphone version of WM5.
I had high hopes of such bugs being ironed out in WM6.
I use the power key to put it in standby, as I didn't want to leave the screen using power whilst it decided to go into standby by itself. Is this extended sleep/standby that I am activating the wrong thing to do? What should we do to get it into a light sleep?

Well I dunno if it's cause by that, but this settings is located in the Power options of the setttings pannel... in the advanced tab you can tell it tu activate it or not and after how long u want it to *turn off the device* (which is what I call gently the "extended power saving")
Just spoke to Orange, apparently the 3G network went down yesterday this coincided with us getting the 3 tytn's so has probably made the problem worse. We were going to send the phone back under the 7 day return policy but have now decided to change them onto the gsm network as suggested by orange and see what happens when the 3G network re-appears.
I had the exact same problem with my Hermes on Orange about 14 months ago - just for a couple of weeks - as they were having network issues on 3g in my area.
3G masts are quite temperamental and if your local 3g provision keeps failing, they will replace them.
I haven't had any repeats of the problems for over a year.
The only annoying things about having to switch down to GSM are 1) no simultaneous data and voice, 2) slower surfing over GPRS and 3) you will get used to the massive battery life increase and switching back will hurt!

Just now I had a second round of this problem at work, and I had the same thing yesterday here. Very f***ing frustrating and since the primary function of a phone is to make calls, it's particularly ****e that it doesn't do it well.
No calls and only one out of 6 SMS's were delivered. I had to do a soft reset and then I had two voicemails and 5 unread SMS's pop up.
If the calls/SMS's were retrieved after a soft reset does this mean that it's the phone and not the transmitter? I use my phone for work and this is becoming a real problem.
I can foresee this phone being off to HTC for 'repair' getting a new unit, flogging it and going back to WM smartphone edition.
No - it sounds like a network issue.
Switch to GSM for a week. Then switch back and it should be fine.

Yeah, I did some searching on the subject and saw it occurred on many different WM phones, and switched it to GSM only.
It didn't fix it, and it simply wouldn't ring. I checked by calling from a colleague's phone and it displayed: 'warning active call divert on' or something like it.
I was most pissed off, as per my previous post.
When I got home, I activated (via network codes) call divert to my car phone number, then sent the cancel network code to deactivate it.
Tested via home phone and it rang. It was active (screen on) and rang withing one ring on the home phone. So I pressed the power button and tried it. Same result, imperceptibly slower if it was slower.
I work in a pre-fab unit made from corrugated steel on top of a hospital (obviously some sort of rapid office space 'solution'), and whilst I get 2 to 4 bars of 3G in there, and seeing the issues whilst on GSM only, I am totally and utterly confused as to the cause of the problem!
The Kaiser is however, on probation. For now
Cheers,
Joe

Horrible Service with at&t tilt...

For comparison sake I have an old stock razr v3xx and I get FULL service in my room with it.
On my at&t tilt, I get 1-2 bars.
Im running Slueth 3.0 (WM6.1) and I've tried different combinations of HardSPL's and Radios but each one gives me problems that I can not fix. (i.e. - some SPL's have certain bugs where i get a text and it vibrates until i change the ringer to silent, and any other radio than the stock slueth (1.64.08.21 - which I need a link to if anyone can find?) makes my camera not work and I get a black screen.
One thing Ive noticed is on my razr, the band always says 3G. On my tilt, it says "H" - which Ive never seen before. What is "H" - and could this be the reason for poor service?
Again, if anyone knows where I could find Radio 1.64.08.21, and the disable xt9 cab I would greatly appreciate it. (I have searched for both but to no avail for a working link)
H is for hsdpa its just a nother type of service, gprs hsdpa 3g are the main in the US.
No "h" it isn't the problem.
try the ultimate radio thread for the radio you are looking for.
yeah i did, 1.64.08.21 isnt in there
can I force my tilt to choose 3G? My razr picks up 3G with full service yet the tilt uses H with hardly any
I have really awful service too. It loses connection from 3G every 10-30 seconds sometimes, but other times it can sit connected to the 3G.
Sometimes it won't even connect to 3G, then when I soft reset, it connects at 2 bars. Right now it's sitting connected at 3 bars.
What's up with this, and is there any way to improve it? The nearest base station is only 2-3 miles away.
I'd recommend trying out different radios.
Also H stands for HSDPA which is considered to be 3.5g but it actually is 9x faster then 3g.
jay487, search harder.. i found the disable xt9 cab in one search for "xt9". as for the radio your looking for, check out the wiki.
if you change the band to GSM in the band tab in the phone settings the signal will get better if you turn off WCDMA which is 3G or HSDPA, if you don't use 3g for internet then turn it off it will help
yeah I changed the band to GSM out of curiosity and it definitely seems to help so far. I dont use 3G for internet just for picture messaging, this shouldnt be affected correct? I also just did a complete reload of Sleuth to resolve the radio issue.
One problem I still notice on occasion is my sounds will just stop working. If i get a text the sound doesnt play, and if i set it to vibrate when i get a text too sometimes it constantly vibrates until i change the sound to silent and then back. I can fix it with a soft reset but having to do this everyday is anoying.
Do you need a specific program or app to disable 3g or hsdpa? i have the exact same problems, ATT +tilt= bad recep and lots of dropped calls
thanks

[Q] HTC One signal drops

Hi all,
I have bought a Htc One M7 handset recently and I have noticed time to time there are No Signals (Limited Service) on it. When I switch off/ switch on or if I turn on the Airplane mode and turn off again, the signals will restore. This is happening around 2 times per day and really annoying. Need to know whether this is a known issue for the model.. I still didn't change the SIM and check. Please help!!!!!
Thanks alot!

I have the same thing
To add some detail for diagnostics see below:
- I travel into London every day and sometimes when signal drops in the tunnels it will never pick back up again after leaving them whereas my old One X did not have this on the same journeys.
- It even dropped out mid call and came up with the sim card icon at the notification bar as if no card inserted (but no selectable notification) first time its happened to this extent.
- Do you have a 4G SIM/connection or are you on 3G like myself? I'm thinking perhaps its something to do with trying to pick up 4G instead and completely disregarding the 3G connection that is available.
- I have also noticed that ever since getting the handset its never had as good signal as my One X which was pretty much always full signal in my normal areas (home, work etc) This may just be the way the handset gauges the signal not the signal itself but something to note anyway.
I'm having the same issue here in the US. It's prolly my only complaint with my phone.

I'm also having this issue but more sever with an all-day no signal. After reboot, I gain signal and I can't make and receive calls.
Try to turn 4G off.

How does one do that? Having the same problem, both wifi AND mobile network drop off. Wifi comes back on its own after a few seconds, the mobile data connection often comes back (obviously if not on wifi away from home), but the mobile network stays as no signal and doesn't come back, unless I reboot or cycle aeroplane mode. I know there's some problems with touching antenna, but this is happening a lot in the car, when the phone is powered and sitting in a cradle.

To turn off 4G you go to Settings -> Mobile data -> Network mode and then select "3G / 2G"
don't know if it'll help though, but trying is worthwhile

Thanks. The problems seems to have gone with that change. Perhaps it is some system thing kicking me off the network because I don't have 4G on my contract and my phone was trying to get it.
Now, if you can just tell me why my lovely 3-4 bar indoors signal on EE has dropped to 0-1 outdoors (as they deny there is a problem)

Are you sure it's not just cosmetic? Try going into Settings->About->Network and see if the signal (dBm) is dropping.
Sent from my HTC One using xda app-developers app
I have it constantly on att - I have to turn on airplane mode and turn it back off to get my network back, I have tried different roms and updates and still the issue is across all roms.
Maybe try this: in your dialer type *#*#4636#*#*. Once the menu is opened, select Phone information, then scroll down to Set preffered network type and choose one of the options (im from Serbia, europe, and I usualy go with GSM auto (PRL)).
Issue with 3g only
Whenever I keep it on 3G, it drops signals for 2 to 7 seconds at random intervals. People often complain that when they call, they get a message that my phone is switched off.. I am probably gonna try another ROM and SIM to see if that helps before dumping this phone forever.
how to solve limited service or loosing service on htc one m7
Hello
it seems to be a hardware fault where the radio is not staying on higher band
it seems to be having issues on 2100 and all umts and hspda or lte networks
however switching back to 2 g can resolve this issue and phone ( hope so) will never lose signals or drop then again
i tried this and for me this works fine so far over 12 hours now no issue
give it a try and see this should work
setting>data>network>2g only
by this you wont have option to use fast internet though but at least you can phone can be used for voice calls messaging etc and also wifi too
I was on stock lolli pop and tried to flash cm12.1 but does not help sort the limited service issue
enjoy and leave your feedback
Edit:
some people cant find 2g in settins>mobile network>preferred network type> lte or 3g only, the solution is go to *#*#4636#*#* phone info>set preferred network type>gsm only( this will put your device into 2g mode)
hope this work

xperia T showing signal but having "no service"

I have had my xperia T for about 6 months or so and since day 1 on both stock .140 and .141 roms my phone would display having full signal or at least a couple of bars, but when i go to send a text or ring it would say no service for a call and unable to send for a message dispite having full signal, a quick reboot and everything was working again fine.
My phone would do this maybe once a week, once or twice it did it a few days in a row then other times it would go weeks without doing it.
I got onto t mobile and they reset some settings, didnt do it for a while but eventually it did it again, I go tmobile to do me a new sim card and the problem went a way for a while, but eventaully started again.
Its quite uncomon it does it really, but then it does it is very annoying, just wondered if anyone else had suffered the problem and found a solution?
Thank You
No one else has ever had no service despite their signal showing bars?
I have done a bit of a test with this and noticed that if I just use GSM only I have no issue, I think the problem is something to do with the way I turn mobile data on and off.
As I am in a position to use Wi-Fi almost all the time I opted for a contract with only minimal mobile data as I knew I wouldn't need much of it. So I only turn mobile data on now and again to search for something if I am away from a Wi-Fi connection. I can't say exactly how the fault works, but I think if I connect to 3g, do what I need to do, then turn off mobile data, the next time I go somewhere and loose signal my phone fails to re join the t mobile network. It continue to display the correct about of bars, but if I pull down the notification bar I can see the phone actually has no service.
It is not until I go to make a call or send a text do I notice this really, but no one can get through to me either.
I'm 99% sure if I use mobile data on GSM I don't have the same issue, it seems to just be an issue with allowing the phone to switch between WCDMA and GSM and using mobile data.
After a bit of a Google search it appears Xperia Z users seem to suffer a similar problem judging by other forums, but no one has come up with any solution.
I think I have had this issue on every stock firmware I have used.
Any ideas anyone? Thanks

Frequent Random Network Drops

I've seen a number of threads where people post about their device dropping network data connectivity, and needing a reboot to solve it.
My issue is a bit different. Occasionally (I've noticed it 3-4 times today) when I go to send a text (SMS) or to use a data enabled service like Hangouts, that my phone shows no bars at all.. not even just no data, but the bars are grey and there's a red x. I wait about 15 seconds and it reconnects, then another 10 seconds later, the data is live again.
Phone is a private sale and under 1 month old, and all the Stamina functions are off.. I do see that the "Queue background Data" is turned on, but I don't think this should effect, no?
Not sure what digits I should be looking at to know if this might be a hardware vs software issue.. build is listed as .93
Im no stranger to unlocking and flashing, but I've kept this stock cuz it's tight and I adore the battery life.
Suggestions?

Been about a month since I posted, and I'm still experiencing this issue. I often thumb my phone on and it's not connected. I don't really mind waiting for the 30 seconds or so that it takes to jump back on the network, but it often means I miss calls, and since it's my business phone, it kinda bums me out to suddenly get a VM notification of a missed call even though it never rang.
Is there some sort of utility that I can use to monitor the network activity to see how frequently it drops, and for how long? I've looked into ones on Play but they don't seem to have a history, just something that shows what data up and down is currently being reported.
Sadly the only Sony store in my city (and I think the country - Canada) has recently closed for good, so I'm not sure how to go about warranty repairs...

I don't have a solution, but I can tell you that you're not alone. I've been experienced the same thing on my Z3C. I sometimes wonder if it has anything to do with the fact that the MVNO I use doesn't support 4G LTE.

Interesting.. Your issue isn't just data, but a complete network disconnection? Im with Fido which is an MVNO under Rogers, but I thought they supported LTE. The issue also persists even on wifi

Yes, it seems to be a complete loss of the mobile connection. When I wake the phone I see gray bars and a red X on the signal strength indicator. Within seconds the phone re-acquires and the indicator goes to 2 or 3 bars. I have also seen it happen with wifi active. The frustrating part is that it doesn't seem to do it often enough to troubleshoot. I'll notice the problem maybe a couple of times a month and there's nothing obviously different about my usage patterns in those instances.
Mine does it at least a dozen times a day. I can only assume this as I frequently miss calls and at least 3-4 times a day I see it happen. =(
Same Problem
Randomly I have no connection at all but after a few seconds everything wents back to normal. Did not have this problem with T-mobile in Germany but with with O2 I have. With T-mobile I had LTE but with O2 I don't, so I guess that's the reason.
Interesting... I've disabled LTE and now have it on 3g/GSM. We'll see how it works moving forward, and I'll post again in a week. Stay tuned.
Service Providers
In the mobile network settings one can change the service provider manually. With LTE enabled my provider has three entries: LTE, 3G and 2G. Connecting two LTE fails, because my provider blocked it in my plan. Having LTE enabled, it often tries to connect to LTE I assume. I switched off LTE and set the provider manually to 3G. Maybe that helps. We'll see.

Interesting.. I have LTE as part of my network and plan... But once I made changes to the settings as I indicated, I no longer receive the network drops I originally experienced.. I might just be missing the alerts, but it seems fixed... #crossedfingers
