hi mine also does this but strangely only does it when i went to stock unbranded firmware which included different modem. i flashed various modems and all the same except the oiginal 3uk modem software which is nele4.

The phone has a problem
Actually there is nothing to do with the contract or the signal towers or how to say.. Sorry im not English
I can tell you guys, i have an iPhone 5 as well even i hate it. Although the signal never drops and i can make a call whenever i want. I hate the iphone but i guess a have to use that.

Low Reception On X10?

has any one else noticed the drop of signal on this phone? it works fine at home but as soon as I enter my college class room, the service can't be found, this is really annoying, I don't receive my texts till I exit the room and even then, every text I send seems to take ages to actually be delivered to the recipients phone. any one know of any fix for this?
running 2.1 official with pitch black theme. Xrecovery installed.
Did it start to happen after you installed the black theme?
Sent from XDA Premium from my X10a rooted running 2.2.1 Pure CM Rom from kxhawkins
no, its always happened. is this a problem all X10's have? as soon as I leave the room/college, it gains its reception again :|
I dont have that issue at all. Have you tried flashtool to try to fix the issue, or seus from sony? It could be a glitch in the phone. Have you used flashtool before? I can help you with that.

I have att x10a with 1.6 and I was constantly dropping calls worse than the iphone.. Called up ATT and they said swap the sim.. Did that and still nothing so they replaced the phone and so far no issues..
I've swapped sims, it didn't help, what would the flash tool do?
It's a hardware issue.
Not much you can do.

Its definitely a hardware issue, at least mine was.. If you’re under warranty get it replaced either via your carrier or SE
if I flash another baseband would that fix it? this phone works perfectly at home and other places, just as soon as I enter college, it loses reception. would another baseband be worth my time trying out?

No.. i have a similar issue.
and there is nothing you can do.
I wrote a petition to my service provider about this.
And the fixed a problem with the tower. "only cuz i know they take budget cuts"
The gsm modem is full of ****.
I don't know if it's a software or hardware issue.
But so far there is no fix for it.
As I posted above I had this very same issue.. ATT says couple of their towers are still down in my area and could be an issue.. It isn't.. The replacement phone I got last Friday has been very good… So clearly it was an equipment problem.. Are you still within the 1 year warranty? If you’re get it replaced ..

Oh.. yes.. sorry.You may have a similar bad chipset.
Thanx for reminding me gabnj
But you say that it is only in class.. so no 100% way to be sure.

You need to ask the network if they are having problems .
Have you checked /remade your network settings ??
Could be a rom problem a modem problem a sim card problem or even a CSC problem with wrong settings .
Check settings clean sim card that does not help put your phone back to a warranty state flash stock rom and clear rom counter . Test if faulty take to a service centre .

Im on 3 also i have had a few times the same problem mate, lets say maybe 4 or 5 times, it usually happens if i lose my internet connection it still shows me having signal but cant make a call or sms. i got no answer from 3 either
Check the status screen. I get this and when it happens where it should say T-Mobile it says Emergency Calls Only. I figured my SIM card was at fault so wedged some paper behind it to hold it in place and the problem has almost completely stopped.

Are you guys running an I-9100T from 3? All modems from any rom you install won't work with the T. You'll need your stock KF4 modem.
Get it here:
http://forum.xda-developers.com/showpost.php?p=15885779&postcount=329
I had a similar problem. Read more about it here:
http://forum.xda-developers.com/showthread.php?t=1225849
tried going back to kf4 still no luck its only in certain places in me house where it does it everywhere else i have 1 or 2 or none at all bars of signal
3 customer service rang me up told them i wanted cancel the contract bcus of it. they knocked the contract price down from £30 to £25.75 for the text 500 plan with them. bit annoyed that i can only get signal in certain places of me house but cant argue on the price as well as gettin the phone for free
because 3 dont have a 2g network in the UK so if you dont have 3g coverage it will show a network signal but you cant make calls or sms
I'm having the same problem but with o2. I lose signal regularly at home as I live on the perimeter, but when I get signal bars back againwhen i go into town, it tells me that the network is unavailable. I have to switch off and on again to re register and then it works fine again until the next time the signal is dropped... It's annoying in the morning because i can wake up and see full signal on the phone all morning, but people are trying to contact me and not getting through because in reality, the network is not connected! I'm sure o2 have a 2g network, so I would presume it's a phone issue...
Hi all,
I live in France using SFR network and I get the same issue here using KI3 but I had the same problem with KH3.
the behavior on the phone is network seems to be good everytime/everywhere but sometimes people who try to reach me go directly to my voicemail and I receive sms with some delays.
When network works again, I mean I don't see it but I know it because I receive a couple of sms at the same time and a call from my voicemail
it means that my phone seems to be connected to the gsm network but is not, It loose the gsm network...
If you can give me your experience.
thx
I've got the same issue. (tacticman), I'm also on SFR network, i had this since KH3, never before. Now i'm on KI3, it's still here.
I always use CF-Root kernel, i tried to wipe, restore old backups, it does not change anything. I also tried GS II repair tools, nothing too...
The only thing I found to solve (temporarly) the problem, switch to offline mode (mode Hors ligne in FR) and then disable it.
But the problem occurs very often, it's very disturbing.
My IMEI number is still here.

Call Drop Outs on S3

ive got an s3 which constantly drops out.
im currently using the Telstra network in Australia which is a pretty good network.
my old phone was a htc sensation xe and i never had any issues with it on the same network.
Since a purchased this phone i constantly get call drop outs at random times even though i have full reception.
I have the latest firmware and im still getting the same issue.
My wife also has an s3 and having the same issue.
Im wondering if anyone may have a solution for this as i really like this phone but its really annoying not being able to use it.

If you want help you must provide relevant info - and also be able to think a little for yourself!
Have you done anything special to the phone before that? Like programming a ROM in Odin?
Is the IMEI in place?
im new to the s3 and dont have a clue about what anything is. ive never done anything to it.....

Hi I think this may be an issue in some parts of the world, but not all. I have regular signal cuts like this in South Africa, but generally only when I'm in an area with weak cell signal. My wife also has a S3 LTE and gets the same signal cuts. When it happens I reboot my phone and it's fine again. I even went back to stock to test and it still happens on stock, just as it did when I first got the phone in November 2012.
I've been on AOSP roms the last few months and then it was fine, no signal cuts. Same with my wife's phone. Now I'm back on stock and the signal cuts are back, albeit not so often anymore, maybe one or two a week. I'm going to run stock for a few weeks and see if the issue persists.
What modem are you using? Have you changed it or is it the same modem that came with your phone?

a MODEM IS A MODULATOR DEMODULATOR . basically the bit that connects to the network .
Modem = Baseband .
\Suggest one factory reset two if that fails service centre and three read the basic faqs and guides .

HELP! no signal

Hello
I got my xperia z2 D6503 2 days ago brand new sealed. I inserted my Net10 sim and it worked like 1 day and than I noticed that there was signal issue first I thought it was because of area than I found out it was phones fault since same sim card worked perfectly on my old xperia z and also on xperia z2 Tab and on my brothers galaxy s4. strange thing is it shows low signal only when LTE is on and I can send and receive text messages but I can't make calls. as soon as I turn off LTE it looses signal and no text or call go through.
I tried factory reset, 2 different sim cards, even bought new sim card, numerous restarts and nothing helps. searched web for this issue and nothing at all.
so anyone else had this experienced? any solutions?
thanks

Same issue with my z2... only when I hold it a certain way... I'm on Bell mobility in Canada and got the phone a few days ago.
I've been experiencing the same issue ever and I've had my phone over a month, I'm on EE in the uk running the .55 firmware. My phone is currently in repair to fix this problem so I'll get back to see if it can be fixed
Sony has no solution in USA and can't repair so I returned for exchange to seller. I though it was only me so looks like gonna be big issue

Hey, so did the exchange solve the problem for you? I am using NET10 as well and while I do get signal on all networks (2G. 3G, etc..) I notice that it isn't as good as almost any other phone I've had. I live in an area that has poor signal and places that I get 1-2 bars on other phones I get 0-1 on this phone, though when I'm in upper town where signal is great I get about the same as others do. I'm just not sure if my phone is defective or this is just how it is. I really don't want to wait to exchange plus the seller seems reluctant to do so..
I had to fix my APN (wireless &networks -> mobile data).
I Google the correct settings for my carrier(ATT/USA), and saved the updates and it worked IMMEDIATELY.
it's been solid since ever since. Note there are differences for the 3g VS LTE versions. Make sure you enter the right settings.
Good luck!

yea I noticed that signal is not as strong as it was on my Xperia Z. even lost signal at the places where my Z was solid. hope this could be solved with future software update.

I did entered correct APN's as I mentioned it was working great for almost day and Than suddenly stopped working so if I had entered wrong APN's it wouldn't worked first time I powered it on. plus same sim card worked well on other LTE phone while was not working on my new Z2, so it was not APN issue.
Try rebooting 3-4 times and then wait. This should solve the problem.
Check the baseband version online and on your phone.
There is also a firmware update but you have to cable your phone to a computer and let it install the Sony software on the PC/MAC ... Mine updated yesterday...
Worth a shot if you haven't done so already.

Thanks man, it seems that's just how the phone is, maybe I can stop worrying so much about that now, especially since this Z2 I have has no defects that are so plentiful on other user's phones.
And like I said, it's not such a big deal when I'm in places with adequate coverage so it's tolerable. I updated to .402 yesterday and there isn't any change with signal but I'm holding out for more updates that can help out with coverage. I'm thinking once the Z2 is released in some way in the US (carrier or Sony store) that there will be an update then that may help us out.
I'm probably the last person to be offering advice in this forum, however, just a couple days ago I noticed I had no data connectivity at all. Calls and texting still worked, but no cellular data. All my APN setting were correct and even though airplane mode was not selected, turning it off and on again got my data connection back. Just something stumbled upon and I have no idea if it applies to anyone elses issue here. Just thought I'd toss it out there in case it helps just one person.

Solve which problem? The one i posted in very first post or the weak signal on my replacement? I did more than 5 reboots to solve first proble but nope.
Now this very weak signal worries me it loosed signal at places where my old Z was great. Hope this phone doesn't end up super problematic
Sent from my SGP521
Sony Service will service/replace the set, if needed. So please do check in there.
phone is amazing everything works smooth, but weak signal is getting on my nerves! looses signal very often and data gets really slow because of low signal even when LTE is available. I live in brooklyn ny and my xperia Z didn't have this issue at all. hopefully this could be fixed soon by software update.
Drop down quick settings from home and ensure LTE is ticked on.

Call sony xperia department let them fix it or replace new one. Don't even think phone can repair itself
Same problem
My sisters got the same problem,
Help line, Tech team no help what so ever !!!
Been on the phone for over 2 weeks !!!
They wont solve the problem what so ever !
One tech team even said "buy a new phone" !! such great customer service !!
They are wanting £150 for it so it can be "fixed"..... also wanting £40 for the month contract despite not having the phone !!!
I understand who you feel... they are no use what so ever and rude...
