Hello,
I updated my Xperia L to 2.17 yesterday,and today,about a few hours ago,my phone lost all signal.
How it happened was weird though-
I first noticed this when i tried to make a call and it wouldn't go through.At that time,the signal bars were full.
Then,i tried to send a text message.Same issue-not delivered,with the signal bars still full.
I thought it could be network issue and put the phone into airplane mode and out of,about 3-4 times.still the signal bars are full,but no call/message was going through.
Fed up,i rebooted the phone twice.Same status! .signal meter is showing full,but no calls/messages going through.
Then,after 5 minutes,the signal meter showed no signal-emergency calls only.
then,about half an hour,network came back up and i was able to use the phone as usual.
It couldnt be a provider issue as another phone with the same provider sim worked fine.I also had plenty of talk-time left so,its not an issue of that either.plus,i was in direct line of sight of multiple towers.
for some background-the sim is about 4 years old.plus,to get 3g working on my phone,i had to play with the settings a bit and it could only be activated after my service provider did some hocus-pocus.since then,i got fed up with their ridiculous prices and shifted back to 2g.
The same sim was in use in a hardy nokia1100 and then a Nokia 6020 till a month back,when i got the XL.and never have i faced such an issue before.
Is it a phone issue?I have attached a screenshot of the battery usage-it shows the network issue in red.
http://forum.xda-developers.com/attachment.php?attachmentid=2177124&stc=1&d=1376067822
Initially,i neglected this in the battery page-this is not the first time the battery page shows network was dropped.it has happened multiple times before,only-this time,i saw it happen live when i was using the phone.so,its not a sudden issue and has been there for a bit of a while.
Another fault i noticed sometimes-when i receive a call-it drops off and i have to dial them back.
However,if i were to make the call,it works just fine.happens very rarely though.
so,do i change the sim or go to the service center?is it a radio/antenna issue?
Kindly advise,
Regards
Suraj
Sorry for bumping old thread. but i got same problem here.

Im have the same problem, what I do? (this is the title)

Hey guys.
I have noticed large variations in the signal that I have. E.g., somewhere that I normally have 2 bars, from time to time it may display 5 bars or no bars at all, but I can still make a call.
The real problem occurs after long period on standby, after which it seems not to recognize my sim. It has happened 3 times in a 4 day period. The problem is solved if I restart the device or disable-enable the plane mode, but this is not a real solution, since meanwhile I've missed a few calls...
I have no weird apps installed, and I am experiencing the signal variation since day 1, without any apps installed.
Any ideas? Contact the retailer maybe? I bought it from expansys on April 11th, what is their DOA period?
Contact HTC maybe? Or get a new sim?
Your help is highly appreciated!
I suffer signal variations too, I can go from 5 bard to 2 bars and back all in the same location.. Ive never had 0 bars, or had a call drop. But its something that bothers me
What you should do is
Check with your provider for any faults in your area
Request a new sim
Contact your retailer
contact HTC
All in that order.
I also have this problem. I have tried a new simcard but still problem. I hope HTC will solve this, because it seems to be a software problem.

Thanks for the quick answer.
I do not mind the signal variation, since I can make calls even with 0 bars (!), of course I don't know if this affects the battery life...
My real problem is, not recognizing the sim... I also forgot to mention that the very first time I inserted my sim into the phone, it didn't recognized it either.
I 'll get a new sim from my provider, hoping it's not the phone's fault.
In the meantime, I 'll let the retailer know about the situation and ask about the DOA period, in case that doesn't work.

You mean, just the signal variation, or the sim not recognized after standby?
you should rly try to get new sim card, could be sim problem.
For signal variation, it probably drains battery life. If signal is weak, or it drops from 1 bar to 0, then back to 1 (had this situation at my work) - battery gets drained RLY fast.
But that was in case when I rly didnt have or had rly weak signal. Dont know with this, but I guess if phone trys to "recover" signal, it will consume much more battery

The SIM problem is a separate issue, which you should hopefully get fixed.
Now regarding the signal strength bars. I have used a lot of expensive RF test equipment. Most of it more expensive than your car. Or house.
None of them measured signal level in "bars", usually it was dBm (mW in 50Ohm). Unless you know what those bars correspond to in real power levels, then it's rather hard to say if the variation of a few bars is something to worry about.
Digital comms systems tend to go from "working great" to "no signal" within the span of 6dB. And that's a very small range when one looks at the variation of signal level in a typical urban environment, even if the phone is static (position-wise).
It's been some days now and I don't have any more sim issues, so all good.
Maybe it had sth to do with where the sim was touching the phone... (I tried cleaning the sim and reinserting it a couple of times)
But the signal variations continue... I reached HTC and they said to try GSM only mode, and also safe mode, but same behavior there. - now rechecking and unsure about results, gosh it seems complete random.
aza314, I understand what you 're saying, but what about this... the signal variations are so annoying, that rarely I might unlock my phone to get a temp "no service - emergency calls only" message (normally I have signal again in 1 minute or so), in the same spot I was making calls normally some minutes ago (or later).
Guys, I need your input here... if you have never experienced such a behavior on your phone, if it's not a known bug, I need to know, in order to report it DOA.
edit: on the other hand, maybe it's related to this issue, so hoping to get fixed in the first update...
Hello,
Recently, I had bought a used phone from someone, very nice Xperia RAY [st18i], but I didn't know that it's sim locked to T-mobile. I went to T-mobile centre and they said to me, that they can't do anything because phone is still under varranty, and If it is they can't unlock. So I made some research, found a solutions like buying a unlock code via weird sites, but the phone Is THAT hard sim locked that I even can not simply insert a unlock code., also bootloader is locked and can not be unlocked. [bootloader unlock: no].
My friend recommended me a solution of buying a "Turbo Sim", so I had bought one of them. It was simple, but there was a need to cut my SIM card a little to fit with a Turbo Sim in a sim container. But it doesn't matter, my xperia turned on and was not anymore asking to sim unlock code, I had just filled my PIN code and ... it wasn't working.. In a few seconds in a progress bar I had saw, that I had no signal,.. then it showed red "x" next to an empty signal bars and then the X dissapeared and again, no signal. Like a loop or something. I was confused, what to do.. I had tryed many times without any luck or success.. another day I had tryed again AND luckily, It was working!! This time it showed me no signal bars, then the red "X" next to a signal bar marks and then it turns to a full signal with a letter "R" next to signal bars [maybe roaming?].. but it was working!
I was glad.. but only for two days when I forgotten to charge my Ray and It went off, so I switched it again and AGAIN no luck! Signal bars dissapeared, - I am sure that the Turbo Sim still works, its not damaged or broken. A two weeks after this, I had tryed again to put my sim into my Ray, and it worked.. I don't know why and how, but it was working!... So I tryed to prevent discharging, It worked for a week or two, but my android messed a little bit and showed me weird things so I needed to reboot.. My signal bars dissapeared again and I am not able to connect to network again.
I am confused, what to do? Does anyone experienced something similar or same?
I had also downloaded an app LTE settings - as those turbo sims are only for GSM networks and there in my country we have WCDMA preferred networks, so I changed this the second time and it worked for a while.. Also tryed to switch on and off DNS server control. I had tryed many different roms just to be sure that It's not software related, I was not able to change kernel because of locked bootloader, I had tryed everything I found on internet without success.
Please, can somebody tell me what else to do? What can I try? Why It is working sometimes, and then for a weeks it's not and than It again works.. It is working always for unlimited time SINCE reboot, than I am not able to catch signal again.. How this can happen?
Every advice would be greatly appreciated!

Well, no-body replied, as it was expected -_- Since yesterday I solved the Isuue - For the others which will be searching for this kind of problem - An user "cadnyc" at youtube said that "T-mobile - some of the users on the forum recommended i plug that tmobile sim card back to a tmobile phone. let me reconnect to the cell towers. make a call and hang up. your tmobile is on its network now. eject the sim and plug it back to the iphone. im testing that right now."
THATS works perfectly! Regards
Hi,
From past three days, signal is not showing up on the phone. And it only shows a red triangle with a white plus sign on it.(Emergency Calls Only)
I didnt do any changes to the phone, it just randomly started three days ago.
I am on Indian version of unlocked Motorola atrix 2 MB865.
I am on jellybean 4.1.2 for past many months. So I dont suspect the ROM.
I have tried using some other sims also.(It is NOT the problem of the Sim)
I usually get full signal at my place.
I have searched internet thoroughly and read almost all the threads related to this topic, but it didnt help me much.
Things I have tried till now.-->
- Swapped sims with many other phones.
- Installed the "Network" app and many other similar apps which was suggested in some other threads.
- Switched Flight mode on and off.
- Factory reset the phone.
- Kept it off for hours and then checked again.
- Prayed that it will get fixed soon
Q) Did you try turning it off and on again?
Ans) Yes..yes.. Many many times. Sometimes, after reboot it shows signal for 2-5 minutes, but I CANT make/receive any calls/sms(The call just drops two seconds after dialling)
PS:- I think that when I received the last call, I was listening music on my headset and I had received the call with the headset.
Thank You very much.

I have now found that it is due to very very poor reception.... For some reason, this phone's signal reception has drastically reduced.
I can get signal only if I go out, still the signal strength is shown at maximum -75dB and frequently dropping to -100dB. I was able to make one call and it dropped as soon as i entered inside the house.
(The same sim on other phones have full range even inside house)
What is the suggested solution?
Thanks

Seems to be a hardware issue then. Is your phone within warranty, by chance?
Nop it is not in warranty.

If you can't afford to help, then what's the point of this post?
Increasing post count I guess.
Might be a loose connection after a drop ?
Your best bet would be to dissamble the phone and assemble again. In the meantime check the connectors and others if they're in their place. There're good disassembly videos for atrix 2 in youtube.

K s h i t i j s, who is your network provider? EDIT: Just saw that you're on MTNL.
I have been having a similar problem for a similar length of time with my Atrix 2 and I'm on stock ICS. I got my sim replaced by Vodafone but the problem persisted so I asked the guy who originally sold it to me to get it checked out (warranty is long gone).
He mentioned that another customer of his with the same phone also developed the same problem around November or December 2013. Both that guy and I are on Vodafone, Mumbai.
In testing, his phone worked perfectly with an Airtel sim and mine worked perfectly with a borrowed IDEA sim. Both our sims work perfectly in other phones. Both were then sent to the official service centre but they essentially threw their hands up.
The coincidental timing of the problem for two (maybe three) phones of the same model leads one to think there must something with the network broadcasting? Could someone with better knowledge of the subject (mine is approximately nil) comment?
Hi
My girlfriend also owns a oneplus one. She had the screen repaired, since then she doesn't have signal all the time. Sometimes it works, sometimes it doesn't. She tried to fix it with another sim but no effect. But last week we went abroad twice and when we were abroad she had signal all the time, and as soon as we got back in Belgium she lost signal again. Now since a day or 2 she has even less signal and she can't send messages or call even with signal.
Just adding that I also own a oneplus and I use the same provider and I have signal everywhere and I have no issues at all.
Anybody that has a solution or might know what the problem is?
Thanks in advance

My girlfriends Pixel 2 has been having audio problems on Three UK recently, during a call the audio cuts out and she cant hear the person on the other end (silence), but they can usually still hear her.
Its been doing it on and off for 6 months usually 5 or 6 minutes into a call. One of the symptoms is the Signal bar drops to empty immediately on answering a call (which sounds fine for the first few minutes even with 0 bars) It returns immediately on disconnecting the call to full.
We live very close to a 4G tower and get a great signal, as well as having tried a three home boost device to triple check the signal. And when hers drops the signal to 0 mine is always full (and looking at the actual signal strength.. its fine before and after on hers, and all the time on mine)
Google replaced the phone on Warranty after confirming the issue, and the replacement does the exact same thing.
I'm wondering if its something to do with VoLTE.. as I noticed when her SIM is in my phone (Pixel 3) VoLTE works.. but in hers its showing not provisioned. (I check this because it started happening not long after my phone became VoLTE enabled on Three)
Anyone got any other ideas or any similar experiences with Three? (It never did it on Tesco Mobile which was her old network.. and didn't do it on three immediately on changing to 3.)
