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
Suraj
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)
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
I bought a new OPO,
When i opened the box it looked so cool! i booted the device and then saw the beautiful screen. But then the horror started.
I opened the sim slot. put in my Nanosim and closed it. It asked for my pincode... When i enter my pincode it just went to the mainscreen and gave NO signal. Then 5 seconds later it asked me to enter the pincode again....
Over and over and over. So i thought..... My nanosim is bricked! i went to my provider and gotten myself a NEW MICROSIM. I plugged it into the phone and 1 2 3 guess what..... Same problem. i kept trying and trying watched 50 videos on how to plug in your simcard correctly...Still the same problem. I tried my dads sim, my moms sim (different carrier)....SAME PROBLEM.
Then i unlocked the bootloader, rooted it and flashed Oxygen on it. Guess what.... Same problem. Flashed back to CM11. Same problem.
I think its either an antenna problem, or a simreader problem. Anyone have any idea what i could do and what this issue might be? Also i received the phone in this state. The day itself i already contacted customer support with my complaint. So i assume this is warranty right?..
Heres a small video i made for the support about my problem.
https://www.youtube.com/watch?v=PgESNaPO7Xc
Thanks lads
I assume you put the sim correctly as you stated, that is the metal contacts facing downwards. Also, have you tried resetting the phone from the setting menu? Another option would be to dial *#*#4636#*#* and choise the correct network option from the phone menu.
Well, what should i set the network to typing in that *#*#4636#*#*?
Have my Z5 since before christmas, was working very well till 7 days ago, suddenly dropped from H+ to Edge, then no network, and its been like that most of the time ever since, do a network search, sometimes it finds all the network, sometimes it finds only LTE, most of the time it cannot connect to a network. when I walk outside I can get a connection, but sometimes it cannot make calls, text or data with full signal on H+, for the last 7 days, if I walk outside by 5 feet away from the house I get a signal, walk another 40feet further I have no signal, walk another 30feet further I have a signal, while I have a Z and a s6 both working fine on H+ on the same network, swapping sims made no difference to the z5, and my sim works in all other phones perfect.
anyone experienced this?

First do factory reset if nothing gets better
Take it to service to check antenna

How they are going to replace a phone with unlocked bootloader and with custom kernel?
Did you flash your phone with full firmware and full wipe?

I did, tried 5 different ftf full wipe everytime.
yea bad move for unlocking, certainly wouldn't go with my current provider again, regardless of unlocked bootloader, they have no intention of replacement.
I just checked the antennas they are fine, only thing I see different is with or without the grey antenna wire connected or not, it made no difference to the signal, sub antenna looks perfect and main antenna look perfect too. there's nothing to is just metal contacts.
if the fault is not the board then it be down to software, the phone works in area with good signal, in town and city I get 4g+ and download speed is great, but upload speed still poor, would it be the ic on the board?
PS. the Z5 is much easier to open than anything else I worked on before
maybe a silly question, but should I unlock the simlock first before I unlock the bootloader? this is my second z5, first z5, a week after bootloader unlocked, no network, no sim work in it, no TA backup but it does work in area with strong coverage, even on 4G+ with full signal
bit worry to do anything with the new one now
Hey guys. I have an unusual problem with my phone.
I was using my phone one night while in bed, playing a game that requires online connection when suddenly, my phone slipped from my hands. I managed to save it from falling to the floor, but it hit the wooden frame of the bed in the process. I checked the phone out and noticed no problem with it. The screen was fine, nothing broken on the exterior. So I tried to go back to my game, but it complained that there was no internet connection. That was when I noticed the signal had disappeared and the phone displayed "No service". I tried turning airplane mode on and off........nothing, restarted the phone.........no change. I turned off the phone and went to sleep.
In the late hours of the morning, I switched it on, and was greeted with the "emergency calls only" warning. I tried removing and re-inserting the sim card, restarting the phone and when I tried everything I could think of, I did a factory reset on the phone. Still, nothing changed. So, to rule out the possibility that the service was at fault, I removed the sim and inserted it into my brother's phone. It worked as it should! I inserted my brother's sim into my phone, same thing. At times, I get "No service", at times, "Emergency calls only", even some times, I get "No sim card", when there's actually a working sim card in the phone. These led me to believe the phone isn't detecting sim cards, but sometimes, the phone recognizes my sim card and the signal shows up, but I'm unable to use mobile data connection, make or receive calls or texts, or even dial a code to check my airtime balance.
So I decided it was definitely the hardware that had developed a fault. But then, one day, I went to visit a friend quite far away from where I lived, and I took my phone with me. To my surprise, my phone worked flawlessly there. I was able to use data connection and was getting good speeds. I was able to call and text. I removed the sim and put in another sim and it was the same.........worked flawlessly. Now, I don't know what to think anymore because as soon as I got back home, I was again getting the No service/Emergency calls only warnings, and the same sims work in my brother's phone - my brother lives with me.
** I know (or think) it's not a software problem because it would have been resolved after I hard reset it. Plus, it all started when it hit the bed.
** I know it's not the service in my area because the sim works in my brother's phone and my brother stays with me.
** I can't decide if it's an hardware problem because sometimes it works, sometimes it doesn't.
Some facts about the phone (if it helps)
** The phone is rooted
** It uses a sim tray. The type that allows two micro-sims or one micro-sim and one sd-card.
** The phone gets hot when I use it extensively.
I'd appreciate any help. Thanks guys.
Same thing happend to my phone it would have a mind of its own but it turned out that out in an open field the phone works but if you get any kind of walls around your phone the network wod not work. This is caused by a hardwsre problem took it to the shop and git it fixed.
