Hello
I bought my Nexus 5 about a year ago , and everything was fine , suddenly i've been facing some problems with network . The problem is i have EDGE with a small x next to meaning that i have no internet , when i change it to H+ it works but it's so slow "1mbps or 40~100Kb in download" sometimes i get LTE with that small x next to it and no connection keeps loading , and sometimes there's no "x" but still with no connection.
So i thought that the problem is with 3g and 4g wires "black and white " , so i changed them with my friend's wires "he has a nexus 5 too" but it didn't fix the problem . So i went back to stock rom and nothing happened
-Tried different modems nothing happened
-Cleaned the whole motherboard with some cleaning tools nothing happened
-Checked the contacts below the "speaker" cover
-Changed my firend's back cover
-changed the sim , tried my sim in another phone and it was working fine
-changed the network operator
-chcked the APN
-did some secret codes to put it on LTE only and i get no network .
I did everything but i still have this problem
I was reading something in some forums and they said that i have change the network IC ! But i'm not sure about it , i mean if i have "no service" problem i haveto change the IC , but i could make calls and H+ is slow but no EDGE or LTE .

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
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

Sorry for bumping old thread. but i got same problem here.
also we are not along. https://talk.sonymobile.com/t5/Xperia-L/network-issue-with-xperia-L/td-p/405833
The signal of my Xperia L fall all time, what I do?
Im have the same problem, what I do? (this is the title)
I stay in africa(uganda) I sold my nokia n900 to buy a used unlocked tmobile samsung S 4G vibrant which has become my worst nightmare...the phone drops network signal and sometimes when I pull it outta my pocket it will show (searching) but will connect after 30minutes else i have to reconnect it my self in network setup..all that was not a problem to me because I work in the capital were network is always up in 5bars both 3G&2G but loses it quickly in some building..
Problem:
When I leave the capital just 15 minutes away it starts to drop signal from 5-0 but will regain in some places...it does this in areas that other people on the same network as me won't get a problem so do my previous 3G phones including the previous n900 I owned.
Things get bad when I reach home in that I barely get a bar in 3G and only 5-4-3bars in 2G it keeps on playing and in that process it will go to (searching) until I reconnect manually which forced me to look for a solution on the internet.
Solution I got:
Connect magnet wire in the back external antenna input at the back of the phone, guess you all have seen that hole, in the video the guy got 3bars from 0-1 bar which convieced me that my network problem is now solved.
Starting the trick:
I cut my tv antenna wire in two pieces, removed three thin silver wires and tested one by one.
The first two failed but the third one brought the network down from 0bars of 3G upto 3bars 3G.
Going on with the test now very happy I try a more fitting object I inserted the niddle which I used to remove the rubber cover which covered the external antenna input.
My nightmare begins:
Immediately after I removed the niddle, the signal bars all went off to X but mine shows a circle and a line touching both sides.
When I reinserted the niddle I got the signal back but this time only 2bars for 2G which was 4-5 bars before and 0bars for 3G which could dare 1bar.
finally:
Now I just removed the niddle, network went off again now my phone was relying on the niddle maybe the internal antenna was now disabled or ruined by me.
I hard reseted the phone, cleared cache but all didn't work..i put back the niddle in the hole It all came back.
Yesterday I took it to a local repair shop and today when I picked it I had -79dbm 2G and -53dbm 3G but when I left the shop 15 minutes away I got an X then 5-2-3 bars of both 3G and 2G..thaugh i got the network back without niddle support. The network is badder than how it was when I first bought the phone.
What the repair guy did:
He rolled a copper wire around the external antenna input and soldered it to an object just near th ext antenna input.
Finally:
What could have been the problem in the first place?
How can I solve the problem?
Phone: tmobile samsung galaxy s t959v vibrant.
State: unlocked and being used on airtel uganda.
Android Version:2.2.1
my last say: I have tested 3 different 3G phones with my simcard and all have performed well in my house with full bars and I don't remember having network issues with my previous 3G nokia phones, my brother who has a galaxy pocket doesn't face network problems either..i have tried all network operators with no success but still the same problem and now come for your help because after the niddle night, alk has become was! I like the phone soo,much cause its my first android but am afraid I can't have it like this, friends call me and it has already disconnected from the network even when the bars are still there in full swing..........
Good day, today I dropped my phone don't know if it lost signal after this didn't notice until I tried to make a phone call but now there no signal, can't make or receive calls, I notice that at the bottom of the screen it shows my service provider name and next to it says no service so don't know it its hardware related or sim, do you think that if I reset the phone it might work again? Thanks. Right now can't test because I'm at work, but in general information on service it says disconnected

Flash stock with fastboot, if it's the same, it's hardware I'm afraid.
Thanks a lot did already, tried everything seems hardware related, noticed that it also lost nfc connection wondering rich part should I replace to fix it, if only has to do with antenna or the whole mainboard
The NFC radio and antenna are connected to the back cover. Try popping your back cover off and on again.

Thanks already did and nothing, could it be related to some other piece?
go to your dialer app and type in #*06*# and see if a number pops up (your imei number) (dont post the number here)
Did too, also the *#*#4636#*#* and checked if signal was turned on, tried sim in other phones works without problems, I noticed that nfc is not working too, guess it has to do with a piece of hardware as far as I know both antennas are in the back of the phone. Took it to service and they told me it has no problem physically, this is driving me crazy
Also checked that it has no reports of being stolen, imei seems correct and legit checked it also on a site to see if it's valid and its working, it starts with a 32.
My phone wouldn't connect to any network after being in airplane mode on vacation for a week, acted like no signal - empty triangle instead of bars. I called my cell provider (T-Mobile) and after a new SIM and a factory reset they did something on their end because my phone was trying to connect to a tower that didn't exist. I'm a little fuzzy on what they actually did, but it worked. I actually had to do it twice over a couple weeks before it stopped giving me trouble.

Hello
Hello guys, I am on the same boat as Valholy described.
My phone fell on the ground from my hands. When I took the phone from the ground... it was still working(it wasn't shutdown nor restart), I only noticed that there was no more signal. Tried to restart/shutdown, factory reset, different sim card but no luck at all... As Valholy described it shows provider's name on the bottom of the screen, but there is no signal yet.. It seems like hardware issue. Any recommendation to fix this issue?
Did you fix your phone yet, Valholy?
Thank you
bump...
any help please.
thank you
Ive had my nexus 5 for awhile, an annoying thing is sometimes when I am in a good reception area, my signal drops ( triangle empty) then few secs later comes back. If i got to setting then more than mobile networks, then search for network operators , once I choose my network , it says that its registering , then registers . All is well again, this happens every now and then. Is this a sim issue or hardware ,or software ? I am on my third nexus 5 and this issue is present still.
Thoughts ? tried everything else , I am sure its either a software or sim issue
