Lose signal and doesn't come back ?

Often times I have noticed with my Tilt that I will lose the signal (simply by hitting a dead spot in the service), and it will not come back until I do a soft reset. First, it shows the indicator that it is looking for a signal, but after about 10 seconds it switches to an indicator with an exclamation point, showing no signal. It never regains a signal after that. Once we get to a place where I know AT&T service works, I will check my wife's phone at that very moment, and she has full signal. We're both on AT&T btw. I know it's not the service, cause her phone never does this. If she hits a dead spot, as soon as we're out of it her phone picks service right back up. I have the stock AT&T ROM that shipped with my Tilt.
Anyone have any ideas why it quits looking for a signal after it loses it?

Ive noticed the same thing.
Not sure of why this happens, but did find an easier work-around than soft reset.
If you go into your phone options, under the Network tab, you can manually tell the phone to search for the network.

I've also had that problem.
I'm not sure wich fix is faster, but using the Wireless Manager to turn the phone off and then back on also takes care of the problem.

hey, i also have that problem.. i'm using a tilt with one of dutythroys roms, with the new .17 radio.. thought maybe that was the problem cuz i never really noticed it with the .11 radio. btw, you dont need to soft reset, just give it a minute or two and it'll come back

I noticed that after messing with KaiserTweak and enabling HSDPA. I live in Minneapolis where HSDPA is now enabled. However, I frequently travel west towards Alexandria, and once I leave the metro area, no HSDPA. If I don't go into the comm manager and disable 3G, I have no phone service at all. Once I disable 3G, I regain phone service.

Ok good, so I'm not the only one.
Thanks for the tip about turning the phone on and off in wireless manager, rather than doing a soft reset. That is, indeed quicker. However, we shouldn't have to do that at all.
I've noticed this a lot when driving home from work. I'm thinking that it's probably because at work I'm in a 3G area, and on the way home I lose it. Is there anyway to disable 3G altogether? Or does anyone know of a tweak that will keep the phone continuously searching before it gives up?

I have that same problem with my TILT, but I also had it with the 5150. It's been around for a while.

Bump again. C'mon people - you gotta give us something. Is no one else having this problem?
For the record, I didn't have this problem with the stock HTC ROM on a different phone.

Having this problem sometimes on a T-Mobile Vario 3, although mine seems to not recognise the sim card after it looses signal. I had thought it related to the phone being cold...

I have the same problems but only with 3G on. When I select GSM only no problems at all. I updated to .17 and wonder whether that's the problem since I don't recall any issues with .11

Thank the lord I thought it was just me. I made a thread about my blue tooth causing it but I realized it is my drive home that does it. I hit an area with no 3G and it goes out.
I have the 10 button comm manager installed and was wondering if that was the culprit. It is weird because EDGE will switch to GSM OR GPRS (not sure the correct name) when 3G is off but 3G will not switch to the others. Does anyone without the 10 button wireless manager have this issue.

Had similiar issues while traveling in certain parts of southern China. Try upgrading the radio from ver. 1.27.12.11 to 1.27.12.17. Follow this link for more info...http://forum.xda-developers.com/showthread.php?t=349528

I am redoing the phone back to the stock condition of how it arrived. I will tell you if it goes back to normal for me.
I will update you tomorrow becuase it is a certain part of downtown Houston that cuases it to go out .

I put the original OS/ROM I am not sure what you call it. For the first time in a long time it switched from 3G to EDGE. I wonder how many of us complaining have the 3G ten button communication manager. I will let you all know more tomorrow after my drive home from work.

can everyone who has this problem start posting their Radio Versions ... please
I used to have this problem with the Tmobile SDA (at that time it was driving people nutts) and that phone did not even have 3G. I did experience the same problem with Tilt (on tmo sim) Radio Version .11, and since tmo usa does not have 3G anyways, I just changed my phone band to GSM and the problem does not exist anymore.

Radio 1.27.12.11
Protocol 22.45.88.07H
in German o2 and T-Mobile network, problem persists after repair trial of HTC.

So 24 hours after redoing the phone back to its original state the 3g problem is gone. I watched it switch from 3G to edge to G all in 24 hours. I will keep you posted if it stays this way.
So basically the big change I had was removing the 10 button comm manager.

I was having a problem that I think is similar, or the same. When I travel from Edge to G my phone will ring and it indicates "connected" but I can't hear the person and they can't hear me. I soft-reset and the phone works again, until I travel back from G to Edge. I ended up reflashing to the original HTC Shipped ROM and I am waiting to see the results.
I am not sure of my radio version when it was flaky. I am using 1.27.12.11 now.

I've noticed the problem described in the original post maybe three times since I bought my TyTN II late in September. It's always been when I'm travelling that this happens. Fortunately I've not missed any calls as a result and switching to 'Flight Mode' and back to 'Phone' in Comm Manager (the standard HTC version) works around it for me. All a very standard setup here so I don't think the problem is a result of any customisations (although I do have HSDPA enabled in settings).

Phone continously disconnects and loses signal if 3g is on

Hey guys, I have this prepaid ATT pay as you go simcard with the medianet unlimited on and the phone goes into a continuous disconnect and reconnect with the 3g signal if I have 3g enabled in the connection manager. If I turn off 3G then it works just fine and sticks with an EDGE connection. Is there something that I am doing wrong? I checked the connection settings with another friend who uses 3g from att as well and settings are the same. I have also resetted the phone multiple times too.
Oh and the phone I have is the ATT Tilt running Hyperdragon's most recent rom.

I'd try swapping SIM with your friend and see if it works for both of you that way. If the Kaiser still can't connect to 3G, you might want to try another ROM, if to no avail you might have the broken 3G radio problem.

I had the same problem. Got a brand new 3G sim card from mobile operator. No help. So sent it to warranty again.

There is a broken 3g radio problem?

Yes, a lot of people including me had to send their Kaiser for a mainboard exchange for that same problem.
Here's the old thread about it I found when I had the problem.
http://forum.xda-developers.com/showthread.php?t=335074

Yes, it's a hardware problem. Seems to be fairly common. My TytnII had the same problem.
I had to send it off for repair last Monday. They sent me a replacement phone on Wednesday.

Oh great, I bought this phone a while back from someone else and was using it with Tmobile and am trying it out with ATT prepaid. So I guess I am not covered and am stuck with a phone with a broken 3g radio?

First try the steps described above, sometimes configuration/ROM trouble can make it look similar.

I tried calling support and talking with them and nothing really worked. They said I would have to do warranty exchange through HTC. They said that all they would need is a credit card number and they send the new one first and I have to send back the broken one and I won't be charged if there is no water damage or too many drops right? Do they send you a completely new device? I have kept this phone inside a microfiber pouch its whole life and there are literally no scratches anywhere and a screen protector on it since day 1. It seems to work fine when on the EDGE network, so should I send it back? I don't want to get charged for anything.

I have the same problem... it started with the stock ROM, I have tried four different ROMs, five different radios, even tried reverting to the 6>0 ROM thiking it was a 6.1 glitch, and nothing worked. I get EDGE just fine, but if I switch to 3G, I get a signal for maybe 30 seconds and then lose it.
Lucky for me, my warranty expired. However, AT&T is supposedly releasing the Diamond soon, I thnk I'll plod along until then.

Phone shows full service but I don't receive calls

Sometimes people call me and get a message saying my phone is off or out of service. But when I look at it, it often shows 4 bars of service..
When I call someone, the problem disappears temporarily, and I start receiving calls again (and I receive all the SMS's I was supposed to get at once), only to appear again later for no reason (a soft reset also solves it). It's not related to location, it also happens when I spend the day at home (where I get a strong signal).
I don't think it's a operator problem either, since my operator is known for it's good services, and other people who use "normal" phones never had such a problem.
I tried 3 different ROMs (dutty's hybrid, Hyperdragon and AthineOS) and 3 different radios (dutty's radio (1.65 something), hyperdragon's (1.70 something), and eMo radio). Right now I'm using AthineOS with hyperdragon III's radio, and almost no programs installed..
This problem happens both in 3G and EDGE mode.
Anything I can do about it?

Send it in for repair?
Seems you tried all you could...

Don't think I can send it for repair, since it's an AT&T Tilt and I'm not even in the US..
Guess I'm outta luck then
Anyone else have any ideas?

have you tried the sim in another handset, sounds like a network problem to me.

3G Network
Are you using 3G Network?
Sometime I use 3G band and even It show good signal I loose phone calls.
I changed to GSM and no phone calls loose.
This happens in São Paulo/Brazil but...
EDIT: Sorry. Now I saw that you reported this problem also using GSM band.
Thanks.

I am not sure if you're using your US SIM card in a foreign country?
Maybe you just forgot to enable INTERNATIONAL ROAMING before you left ... ?

I'm having the same problem
I seem to have started with the same problem about a week ago. A couple people complained that they called me but it rang twice and went to voicemail - My phone never rang. However, after I made a call (or apparently did something to "wakeup" the phone), I would get the voicemail notification (2 hours later).
I tried reseating the SIM card, but then it went to "SIM Card Missing". I did a hard reset, but that didn't help. I took it back to AT&T and they replaced the SIM Card. That seemed to work again, and certainly would have been a convenient fix (bad SIM card - too easy). So I've just spent all weekend reloading all the apps, but now it's happening again!!
The symptoms are; After I reboot the device, I can receive one or two calls, then it doesn't ring anymore (the caller hears 2 rings then it goes to voicemail). If I cycle the Phone radio button in the Comm Manager, or cycle power, it comes back to life for 1 call, then craps out again.
I'm just using the standard AT&T ROM (without the Bloatware after this past reset) and the standard/default radio version 1.27.12.11
The only thing that I have noticed that seems different lately is that the "Comm Manager" task is always running when I look at the running programs (which I don't think it used to) I had also recently installed Garmin XT.
The device is of course 1 yr + 2 weeks (so I assume just out of warranty)
Any help would be greatly appreciated!!!

Hmmm,
what I would try, is, to just make a hard reset, load only my contacts to the phone and run it for a while to monitor its "Incalling" behavior. If everything seems to be fine, I would go ahead and start installing an application, then monitor my device again for a while, if everything is fine I will go ahead install the next application ... and so on. That is just to make sure that no 3rd party application causes this problems.
BTW:
I don't think that GARMIN causes this problem. I used to run Garmin on my HTC too (v5.0) until I came accross SYGIC McGuider (which works much better and card scrolling is much smoother than Garmin).
Well,
to come back to the point: if you get the same problems without loading any 3rd party application on your device, then I would recommend trying another ROM (best advice: go with the HTC stock ROM). If it also happens with the other ROM then it might be hardware related and difficult to fix.

Thanks - I knew that's what I should do, I just didn't want to do it after having spent all weekend reloading and configuring it. I thought I had read somewhere about Garmin having to have the phone radio on to work, so I was hoping there was a setting somewhere that I was missing that was powering the radio down. But..... I suppose it's time to go back to common sense and just do the reset
So far it seems to be working now. I'll give it a few days with just the basics and then start reloading one at a time.
Thanks for the quick response!

Spoke too soon
looks like I spoke too soon, it's doing it again - seems like it was fine for about 3 hours, but now .....
guess it's time to try my luck with AT&T - time to see how good their customer service is

Well, I'm experiencig totally same stuff here. I don't know whats really going on. I've NEVER before had such or even simialr problem.
Ive installed stock HTC ROM. And its going again.
One question. Are you using Opera Mini maybe?

no, I was just using the default browser.
I've got nothing installed on it at this point so I'm guessing it's hardware related.
Over the last couple months I had been experiencing some strange battery drainage (not related to the GPS issues). I don't know if that was a symptom or not. It just seems like the radio is going to sleep somehow - it wakes up for a little while if I sync my email, cycle the radio via comm manager, or cycle the power.
Anyone know if there is a setting somewhere that controls that? (sure would be nice if it were that simple)
The AT&T store was basically useless, all they did was give me the phone number for the warranty department (but since I'm 2 weeks past warranty, he doesn't think they'll help me), and of course offer to upgrade me to the Fuze for $375 - no thanks!

I've had the same issue (I think). I too think that it seems to happen when I have a 3G data connection active and moving back to GPRS (non 3G) seems to make it better....
I'm on a standard UK ROM and using BTMobile as a provider.
I was driving down the motorway the other day and overtook a friend. He rang me and went straight to voicemail. I then got a text to say that I had a voicemail and rang him back.
I was running TomTom Traffic at the time so would have had a data session enabled....
I think its something to do with the data session sometimes not letting a call through but can't put my finger on anything and certainly can't find an option to change any settings...
Also, even at home, I'm constantly picking up my phone to see that it "has no signal" and the exclamation mark is displayed - so calls aren't coming through - but it then connects and shows a three-bar strength signal. Don't understand why it keeps dropping out, but I get a 3G connection at the front of my house and an ordinary G connection at the back and I think that it sometimes to stay connected to the 3G connection for data even when the phone signal is very poor and it would be better dropping that and connecting at "old" GPRS speed...
Same on the train on the west coast main line out of London. I think having the 3G turned on causes the phone signal to drop out completely more than when 3G is turned off, as the phone tries to hang on to the signal of a 3G cell and doesn't successfully switch over to the next "non 3G" cell whilst in a call.

have you tried a new radio such as NIKI's?

well, AT&T warranty was even less than useless. Home phone, Internet, and Wireless all through AT&T and the best they can do is "see if they could get me a deal on a new phone" or refer me to HTC technical support. Nice customer service AT&T!!!
HTC technical support was actually trying to be helpful, once she found out I already did a hard reset, she referred me to their warranty group. They looked up the S/N and it's still under their warranty (I guess theirs is 15 months after manufacture date). Now the only problem is I have to send it in to them to see if it's covered under warranty, and of course be willing to go without my phone for 2 weeks (and pay them a yet to be determined amount if they decide it's not under warranty).
I'd like to try a different radio, but looks like there's too much for me to read up on - I need to get the device fixed, I've already lost too much time with it being messed up and me screwing with it.

Update
so this morning I was ready to throw in the towel and send the device back to HTC. At least they were willing to help me out, unlike AT&T.
I get to work, and of course the phone seems to be working (which isn't unusual, it works for a little while then craps out). Come lunch time, it's still working (now this is unusual, it must be a fluke, I'll give a couple more hours before I package it up). 4:00 and it's still working! Now I'm starting to wonder if it's got to do with the cell towers near my house (and the AT&T store since it did it for them too).
I email my buddy who lives about 1/2 mile away and also has a Tilt just to see if he's had any similar problems. He calls me back laughing. There's 5 People in his office with the exact same problem (and not all Tilts either).
So to make a short story long....... it appears to be a problem with AT&T, NOT the device (but Thank You very much AT&T for the incredible customer care you demonstrated and for trying to screw me into buying new devices for outrageous prices)
So at this point, I'm not sure if it's that AT&T has fixed the issue across the board, or if it was the "Resync the routing" that the online chat person tried last night that finally propagated across the network (I assume so that AT&T can find my phone in order to route the calls to me).
I guess we'll see if it does the same thing when I get back closer to home tonight, but I'm relieved that it appears to be fixed.
Thanks everyone for the suggestions! Now I have a little more time to read about how I can screw up my phone on my own schedule - all the practice of resetting it and reinstalling everything, and seeing how much faster it is has inspired me

Hi bbaydiver
Did Att fix your problem? I had same issue with my tilt 8925. I tried all the orginal Att rom "same problem". After couple minute, I can't receive and make call. thanks

Just a "me too..."
Hello everyone. I just wanted to report that I'm having the same issues...they started about a week or so ago.
I've had my AT&T Tilt for about 8 months now (it's a warranty replacement for my first tilt, bought in July...so of course, I'm out of warranty). I recently had problems receiving calls, and then I started being unable to make calls, even though my phone shows a decent signal...anywhere from 4 bars to 2 bars. When dialing, it'll say "Dialing..." for a few seconds...and then it clicks off. A soft reset will fix things temporarily, but that's it.
I'm running the stock AT&T ROM (I'll check the version number if someone thinks it'll help), and I've tried doing a hard reset AND replacing the SIM card. Same effect.
Someone please let me know if they resolved this problem. AT&T offered me an HTC Fuze...but I'm extremely wary of other phones by this manufacturer. I'm very, VERY tired of phones crapping out on me after having just spend a couple of hundred bucks on them. At this point, I'm just looking for something reliable. If someone else here has had problems with the Fuze, please let me know...not to start any fights around here, but I'm actually thinking about going with the iPhone.
Thanks.

Strange issue with Sim card

Few days back I had issue with the USB module. I went to samsung repair store to fix it (not the authorized one ). After that I was returning home and mid-way the signal went to zero. I tried different roms, full wipe, stock rom but nothing worked.
Now the strange thing. Next day i was going back to work and mid way the sim started working, even 3G was working fine. But again when i was going back home the same issue happened.
So i tested and found that 1km around my house, i get no signal and the same issue occurs on few other places. Same sim works perfectly on other phone.
Has anyone faced this issue?

Sounds like your device is having trouble registering at your local base station. A call to your service provider might help. Good luck!

also check your logs for rill crashes. You could have a rom with faulty issues there.
Or you may not have connected the usb module correctly. You may need to check if all connectors are properly aligned.
However its more likely if its at the same geographical location your connection breaks that its a bad connection area. Call your provider and tell them lol

Network outage issues on Note8

Hi
I have been having issues with my Note8. It loses the cellular network periodically, and doesnt acquire it back. A reboot is required to get the network back but then doesnt last long. I have tried most everything. Listed in order
1. Reseating the Sim / Removing the SD card to check if that was an issue
2. Switching network from 4G to 3G to see if that was the issue
3. Factory reset a few times, including once while not installing apps and letting the phone run with less apps
4. Changing SIMs
5. Changing SIM tray with an S8
6. Using another network sim card
7. Running the phone in Safe mode.
I have exhausted everything that I can have done. Any other thoughts or suggestions?
Phone is within warranty so I can get it fixed, but the issue is that I live in a different country now and they will charge to just take a look at the phone.
Side effect is that while hunting for the network, the phone gets hot and runs down the battery.
I am hoping that there might be a software issue, as the phone does connect to the network for a while before losing connection.
Any help would be much appreciated.
Thanks a lot.

It looks like you have done all of the obvious stuff - it's starting to sound like a hardware fault to me.

Thanks! My worst fear unfortunately.
Was hoping someone might have a software solution or something else which I could try but...

i had same problem with 2 x galaxy s8
after they test for a month and big fighting with those F customer care
they replaced 1 with sealed box and the other one they changed the motherboard which doesn't help , still same problem
i sold both
