[Q] No Signal. Limited Service. --- HTC Sensation

Hello people! I am a newbie on Android, so don't expect me to know deep stuff about Android.
So, I've been using HTC Sensation for about a month now. I've been using it without problem, but suddenly on one night, hard rain strike Bangkok. Suddenly, my phone goes no signal and limited service. I thought it was some some problem, so I wait for a while in order to get the signal back. About 20 mins later, my signal bar is back, but still no Mobile Connection icon (e.g. H or 3G). The worse thing is even though my signal bar is back, I still can't make/receive any calls or sms to/from anyone. I thought it might be some problems with the towers, however, when I switch my SIM to my mom's iPhone, the signal appear to work and the connection worked without problem.
That's when I thought its the problem with the phone. But... when I went out of my area (house), signal appear to work with 3G and I can perfectly make calls or texts without problem. When I got home, No Signal once again. So now I don't really know if its the problem with the network or the phone...
This really annoys me as heck. If someone can give me advices, I will be much appreciate. Thank you very much

My phone goes from having full bars on 4g to nothing randomly me having to pop out the battery to get service again.

Tired of the same

i decided to make the jump and my issues went away, i would have preferred to remain stock however i don't like to be branded, stuck with bloatware etc..

thank you and all of you reply this thread. I am very new to Android, so I'm not really sure about 'rooting'. So Lostcat, you have this issue? and your issue went away after you've rooted your phone? Also, if I am going to root my phone, will all my data, contact, apps, and setting gone? If yes, anyway to do easy back up?
Thanks

I was having similar issues so I sent mine off for repair (through carphone - they say they send htc phones off to the manufacturer but considering its only been a week and they have reapired it i doubt that it has been sent off) still im sort of glad it didn't go off http://www.bbc.co.uk/blogs/watchdog/2011/10/htc_phones.html - im going to get it this afternoon. will report back with findings

You have answered your question yourself here.
It's clearly a problem with your local cell since that night with the hard rain, since when you go to a different area your phone works fine. Contact your network and report theres a problem with your local cell.
cheers

Are you sure? Why does he have a signal in his mum's iCrap?

Yeah, at first I thought its the signal problem too. But when I switched SIM and put it in my mom's iPhone, it work. And I use her SIM on my phone, and it worked too! Pretty confusing eh?

Alright.... I've decided to give my phone to the HTC support to fix it after I've asked a lot of people and they said its the antennas problem. Anyway, since I phone is rooted, in order to give to support, I need to unroot it.
I know people posted a lot of steps on unrooting HTC Sensation, but I want ONE SPECIFIC SAFE and SURE steps for unrooting... Thank you

I tried many roms,kernels,mods and fw. I didnt have this problem before I rooted my phone. I use ARHD 6.2.1. now. problem still exist.

It is cause you are using the wifi calling it has bugs and drops calls it also all ways runs in the background even when wifi is off I suggest unistalling it via titanium backup or at least turning it off when making calls

I have only had those problems with wifi calling and it is included on ARHD and is on by default you will see a lil blue icon in status bar if it is one , otherwise you might have a faulty device or bad reception where you live cause I have not had it or seen this issue about the phone
Sent from my HTC sensation 4g using Tapatalk

It couls also be the sim, try yours in a differnt phone and see if the issue stays with the sim or not

I read that some users have this issue too, but couldt find solution

I have the same problem with ARHD 6.2.1
My workaround is to disable 3G mode. It seems that the phone prefers weak 3g cells over 2g cells with good signal strength.
Install one of the GSM Monitors from market. If your signal strentgh ist -100dBm or more, phone calls get unstable. After switching to 2g mode (Settings - Mobile Network - Network Mode - GSM only) I have -75 - -90dBm now and more available cells than before.
Phone Calls are stable now.
Before that I tried to downgrade to another radio but no luck. I never had this problem with ARHD 3.6.8 - 3.6.13 that I used before.

No, it happens with gsm calls, I turned off 3G and still happens.

You might have a faulty phone or case the antenna in the cover may not be connecting right if you have T-Mobile you send it in for warranty they are pretty good about that up to three times in the first year and its free

anyone know this fix ???????????

Did you guys purchase you handset through a mobile carrier in your region, or purchase it online from another country?
If it's the latter, you may need to look into flashing a more appropriate radio for you region.

Anyone have this happen?

So a couple of times my phone won't let me make calls. It tries connect and then does a short beep. I have to do a airplane no airplane mode to get it.to make.calls again.
Sent from my HTC One X using XDA

It happens to me couple times too ... too bad my 30 days return expired.. Planning to go through warranty center now ... It's kind of annoying because it happens kind of randomly

I have this same issue. They swapped the sim card so I'm going to see if that fixes the problem.

Is it a phone or network problem? On my third phone
Sent from my HTC One X using XDA

I just got my sim swapped, and it still happens.. It looks like phone because my phone has full signals while it happens. It usually happens after long charge

I believe it's a software issue. HTC issued a statement regarding the WiFi issue, that until you get the OTA fix, you need to turn WiFi off and on again to deal with the bug. I haven't had the issue with phone calls that you're having, but I have had the phone drop the mobile data connection completely, or sometimes get locked to EDGE. The Airplane off/on trick fixes it, so I suspect it's similar to the WiFi bug.
If you can put up with it for now, it'll surely be fixed with an update before too long.

Good. Just wondering because everything else on this.phone is good. Ty

Never lost data on this one bit had the no calls yesterday. None today. Maybe it will be ok. Someone said it.may be fixed. Just don't want to have to return the phone again.

Is a fix on its way?
I had this happen to me two days ago. The status bar indicated that I had a good connection and I was able to send and receive emails and use the web browser, but I couldn't send/receive texts or phone calls. After a restart, I had two voicemails and a few text messages (from an irritated wife!). I had been trying to make calls and send texts when she was calling and sending texts, so I wasn't just missing notifications.
Any word on whether this I a software or hardware problem? I still have some time before my 30 days is up and I tempted to go back to an iPhone if there is no fix.

I hope HTC releases an OTA soon...

This sounds like a network problem to me. In high traffic areas where cellular towers are overloaded , ATT service literally stops working. My entire trip to NYC I had no working service in Manhattan for this reason, and every professional sporting event I've ever been too the same problem has occured.
The "bars" were always good, but no texts or calls could be placed or received.
This happened on my a777, solstice, HTC aria, and Infuse

Seems like a reasonable explanation, except it has never happened before and was fixed as soon as I restarted the phone.

This happens to me EVERY time I am in an area with no (or really poor) service for an extended period of time, one of my classes doesn't get service because of the location of the building.. I've already gotten a sim swap and had my device swapped, it still does the exact same thing, only way to reconnect is by restarting the phone or turning airplane mode on or off. Hopefully it's not a widespread hardware issue and just a software issue that HTC can fix. Only problem is that AT&T has a history of taking FOREVER to get out an update that a manufacturer releases.
Oh and this never happened on my Xperia X10, even in the same class where I lose service.

OTA Update did not fix WIFI calling.

I just got the update today. According to the changleog it was supposed to fix WIFI calling. However I saw absolutely no difference. WIFI calling still crackles and chops all the time and it has unusable echo with the speakerphone on.
On top of that now Fligh mode always shows "Turning off..." when I have the WIFI turned on. I did a factory reset, still no change in either one of these issues.
What is your experience with the new software?

I don't have the static that I previously had and the delay doesn't seem to be as bad, however calls aren't consistently coming through to my phone (over wifi calling) since I did the update.

I also found that Wifi Calling got worse with the update. A lot of people saying their calls are going straight to my voicemail, and when I try to dial out I have to try a few times before the call actually connects. Also, the crackle and pop noise is still present as it was before the update too. I hope more people complain about this issue so they can patch it sooner!

I'm also having the same issue and I'm having to rely on that service more because for some reason I don't have that great of coverage in my area anymore. Went from having great 4g at my house to being able to barely pick up 2g
Sent from my HTC VLE_U using Tapatalk 2

Yeah same here with the problems. I get the crackling and popping now. I actually think it started since the update. The other weird problem is my voicemail icon does not go away even after clearing all the voicemails. Not sure if this is because I pay for the VM to text option? Oh and lastly when people call, it shows up as unknown a lot. Dunno WTF!

Going to settings option then call option there's an option to clear voicemail notifications. I just got the phone today and had to do that to clear. I haven't tested calls over WiFi I'm going to give it a try in the morning I hope it doesn't disappoint but it seems everyone is having issues.
Edit: I just gave WiFi calling a little test by calling a 1800 porn number and unfortunately I do hear some cracking or popping every couple of seconds.

I don't think you're going to get cell quality with WiFi calling. I had issues with the g2x as well.

OK I'll bite...
A few things before I give you an answer here so answer these honestly ok...
1. What router do you have and what frequency is it set for and how long have you had it.
2. What's your providers bandwidth that your using? Is it DSL, broadband, T1....
3. What security are you using on your router when you connect to it?
I'll check back in the morning and give you an honest answer....
EDIT: people are expecting 4G quality from the internet and you'll NEVER get cell quality even with the best router running a T1 connection dedicated to just wifi calling, this is a free service for those who have minute plans instead of paying for unlimited service. There are ways to clean up the quality of these connections if your willing to have the patience to reconfigure your router a little and how good your ISP is and working with the limitations if there are any.

Mine is usable as well, just the popping noise is quite a nuisance.

No Calls on Wifi

Hey guys.....
I have an issue with a phone that maybe you all can help with.
This is my second phone doing the same thing the last one was doing.
(yes I've searched)
So occasionally while connected to wifi I dont receive any calls, texts, or emails until I pick up and use my phone for something.
Just now when I picked up my phone to check the weather at 6:30pm and I got 4 text messages, 1 VM and 2 emails all ranging back to around the last time I used my phone. (5:45ish)
This is really irritating as I have missed some important calls lately and it really pisses off my wife...lol...she assumes I'm gaming and ignoring her.
I remember reading somewhere that this phone has issues with going to sleep and Smart Sync.
Specs:
ATT
HTC One XL
ViperXL 2.4.1 (it does this on the stock rom as well)
ViperXL kernel
Thanks for any and all help!!!

I seem to have had similar issues except it was doing it off WiFi. They way I started noticing it was I set my weather to update every hour and I would find it would be 4 hours ago last udate. I also noticed texts coming out of order and calls going to vmail without ringing. I played around flashing different radios ,roms and even changed sim card multiple times. I came to the obvious conclusion that it was actually att issue. I live in a rural area where I get H+ but no LTE. I suspect that the tower cell fills up then puts active calls and data priority. I had atrix before my hox and it did same thing. Its really annoying. So I find myself rebooting phone and it solves issue at least for couple hours.

I don't think it's an issue with Att.
I just got a the email for this, it is an hour and a half late. I am connected to Wi-Fi and my phone is set to "smart sync".
If this was an ATT issue then why didn't I get my email?
The phone receiving emails while on Wi-Fi has nothing to do with ATT.

I also have the same problem. On Christmas I sent out a mass text to people and never got any responses. Then about 12hrs after I sent a message to someone else and got 100+ texts and 3 vms. It was ridiculous. I'm on ATT and running Nocturnal Dirty ROM. But it also did it on other ROMs. I would love to know what causes this problem and how to fix it...
