[Q] calls over 3G - not stable

Hi,
I just bought my Xperia T in Romania.
Operator: Orange
The software version was 4.0.4 Central Europe.
When the phone is on 3G network , even if it shows full signal, the calls do not go through.
I have to wait few minutes or restart phone!
Sometimes is works, sometimes it does not.
Also who is calling me says that the my phone is disconnected.
This does not happen on 2G network.
What is the problem?
Operator related or should I take it to warranty?
I changed from HTC Desire and did not have this problem.
Also I tried the JB update and the same problem

Take it back to the shop, I never had that problem with any rom.

damn it !
I was hoping that someone else had this problem and maybe related to radio version (used with my previous Desire).
But I see that there are no radio versions for Sony. Just baseband which I understand is embedded in ROM.
Oh well... two more weeks with my broken screen Desire till I will get this one back

So, after two frustrating weeks and sending the device to service and getting a response "defect not confirmed,
I went to the service explained them and FINALLY they understood
They replaced the motherboard in half hour and left happy from the service center.
BUT, as I was in the car discovered that there was no google apps, no way to input google account, etc. and the software version was the first one for LT30p.
As I did not want to go back I got home and hoped that a PC Companion update will solve the issue.
But surprise, it said that there is no update
So I installed the JB FTF and the 3G problems again
I also tried more Stock FTF and the same problem
So my question: might there be a problem that the FTF I have been using are for LT30a (which is for 4G)
Is this possible?
I even tried unlocking the bootloader and EMMA only shows .195
Any ideas because I don't want to get it back to the service.
I am starting to think that this might be a LT30p vs LT30a software.
Does anyone know how I could see what are the official firmwares for my phone?!
Is there a way to get my hand on a user/password for EMMA ?
Thanks

You are telling us that you are using a firmware which is designed for LT30a on a LT30p?
The baseband is different for sure.
You can flash JB version for LT30p with FlashTool.
Im using the same LT30p on orange ro and had no problems.

No
I was just wondering if maybe there is Sony issue because if i go to sony support website it only shows Xperia T (LT30a).
Maybe there is a problem with how I upgraded to JB.
Regards

I think I am seeing the same issue too now with my xperia V on JB stock.
Phone has connectivity but calls and sms are not getting through when it's on standby. It's fine immediately after I wake the phone up.

Have you paid your bill?

That's weird, my mobile data also stopped working around the time the OP posted
I am not joking either, I haven't been able to get it working again - I just figured the custom rom I put on recently had screwed up and I'm currently in the middle of getting all the files ready to put eXistenZ ROM on instead - happened to see this while looking for a 253 ftf for the kernel.
Probably a coincidence but still weird.

Try reflashing stock kernel

I think you need to request the configuration settings in your network provider.

UPDATE: Just found out there's a major outage of 3 UK's mobile internet! No wonder my mate couldn't connect...
Hmmm. Strange. There's a bloke here at work who's having the exact same problems with his XZ.
He's on 3 (UK). Swears blind it was connecting and working yesterday - this morning, nothing. His phone signal is fine, just not mobile internet.
Checked his APN settings, his mobile Data is "ON", the phone knows it's connected to 3, it says he's picking up HSPDA, but nothing will connect. It won;t even connect to re-install his internet settings through the "Xperia" menu in settings.
He says it did update to the .253 firmware on Sunday night.
What networks you guys in the UK having probs with?
(I'm only bothered cos I;ve got the exact same phone coming today on the same network )

Xperia V signal antenna problems

Hi
I have problem with signal antenna since 2 weeks ago on my xperia v, I lose my signal antenna randomly, rebooting sometimes help but it is very annoying because I always missing important calls... I googled it and according this threads form sony mobile help center get this result at last: It seems the Xperia V JB 4.1.2 firmware find a new bug for signal antenna. Now, is there any one have the same problem here? I didn't solve my problem yet but I think we can talk about that and find out a ceaseless solution. Please let me know your experience and idea about this problem...
Thank you

i don't know for sure if my problem is related to your's but it's similar i think..
well my one sometimes can't get signal for some while after boot some times..
more frequently it says that the sim card is missing despite showing carrier name and proper signal sign..
i always have my problem solved just by entering airplane mode and out so it could reconnect to network.

It can be firmware bug too. airplane mode sometimes works for me but I have to reboot most of time. another experience or idea?

No idea or experience?

I know the post is old and others, but now I just got a V xperia LT25i.
In which I have had the problem of the radio signal, and it was as easy as that the signal cable inner radius, had broken [incomprehensible], since neither has shock or anything, and it was something sudden, as it has I been running well for a long time, in the hands of someone else ..
So anyone who may have this problem, remove the cover [are 6 or 7 screws], and on the right side check that the cable is good, and if change is broken, and if it's okay, then the problem is Software , rather than hardware ..
Thanks for your effort.

[Q] C6903 weird SIM / network error (with really bad timing)

Hi you all! Please help a girl in trouble!
Some time ago I flashed 3SE rom (1276-2189_14.5.A.0.242_R1D) on my phone because ..well.. the Nordic combined lollipop update took ages and I didn't wanna wait no longer.
The flashing went well and the phone worked properly. About one month ago the usb-cover came off so I sent it to get repaired.
Yesterday I finally got my phone back after three weeks and was such a happy girl. I flashed the customized NCB (1276-9897 14.5.A.0.270_R1D) to get rid of the 3-logo when booting. Then I moved all my photos n stuff on the phone... and first after this I inserted the SIM-card - only to notice that the phone does not work.
It won't connect to network. Says stuff like "invalid card", "emergency calls only". Everything else seems to be OK. I have tried a couple of SIM-cards that work in other phones, but nothing. The cards are not home cut, they are original micro sims. I took the sim lock off also, but it does not help.
I have tried flashing several roms, but still the same. I noticed that on some it get's some kind of signal strength, but on some roms it's just 0. I've flashed with flashtool and used also Sony PC Companion. But still the problem remains.
The IMEI can still be seen. On the phones package is the text SI 1276-2949.11 (FI, DA, IS, SV, NO). The phone is less than one year old.
Before everything got wrong the bootloader was unlocked. I checked with Flashtool to unlock bootloader and it showed the IMEI and redirected me to Sony's site, but I got a bit scared if some quarantee would get void. I don't remember the BLU redirecting me before to Sony's site if I have fiddled around with the phone and Flashtool..? The phone is unrooted and I would want to keep it that way. [Edit: it says "Rooting status: Bootloader unlock allowed: Yes"]
Now I am only very confused, and very stuck.
One thing that makes this crappier is that I am leaving tomorrow for my vacation, a trip that will last over one month... I really need my Xperia Z1 working and with me (and I really should be packing etc. instead of googleing and trying to figure out wtf I've done this time.... Unfortunately I really need that phone with me ).
Can somebody help, does anyone have any ideas?

And of course I have also tried the SIM cards with some paper behind them so that they would fit tighter.
If I try to put the APN manually it says that "Access Point Name settings are not available for this user".
I just tried once again to fix the phone with PC Companion, no luck.

Hello!
I can't find much to do but try to downgrade to a previous working version that was on your phone, and completely wipe everything (with stuff backed up of course) and see if the sim works, then update using PCC.
That's all I can think of, good luck and have a nice trip!

Hi and Thanks for the hints!
The 3-version of Lollipop worked earlier, but not anymore. Unfortunately I think it is the only version I can find from those that has worked on the phone earlier. Can't seem to find the original anywhere. I have had some backups of the phones and firmwares, but my computers got messed up, so I've lost some of the roms (and of course I have tons of other stooopid backups and their backups )
I'm trying to downgrade to some 14.3. global thingie right now, but my hopes aren't too high since I've done this already few times.
And thanks! I am sure that one busted phone can't mess up my vacation even if it makes it much complicated (water resistant, good camera, gps and battery etc.) But hey, what the heck, it's summer and I'm off duty

At least they are proper phones that actually DO work.
It's a shame I don't have any of those good ones left.

No other ideas whatsoever? Anybody? Mumbo jumbo voodoo? Rain dance?

Can you see your imei in the service menu?

Yes, the IMEI is there.

Got it fixed in another country in three days!
The service company I used first had broken some chip on the phone... Won't be using their "services" anymore.

Glad you got it fixed.
So it was a broken chip? Or did the chip get damaged when the first company tried to fix this issue?

Call dropping after 58.1.A.5.159 update

Hi folks,
after the last update I have a big problem: when I start a call suddently the signal goes 0 (on both SIMs) and I receive a "no network" error. After a few seconds the signals go back but sometimes I have to wait for 15 or 20 minutes to call otherwise the call drops again.
It happens even when receiving calls.
I have this problem at around 30/40% of calls I try to make and this is very disappointing because I use the phone for work and I do many calls everyday.
A user on an Italian forum had the same problem two updates ago, he told me that he solved after a reset of the phone. I'm desperate now, tomorrow it's holiday in Switzerland so I think I will do it.
NOTE: It's strange nobody on internet is talking about this problem... It's only me?

Having the same issues with this build.
I have the HK dual sim, which I flashed the SEA firmware onto last year.
I'm having to go back to my old phone until this is resolved, I have missed several calls because of it. I tried a factory reset, which seemed to clear it up for a short while, but the problem came back.

Same problem here. After the update of
51.1.A.5.159​I cannot receive or place calls
I cannot receive or send messages
IF I am inside a building. The network goes from 2 bars to 0 when I try to call. If i go outside of the building the cellular network is stronger (full) and calls are going through. I suspect there's something wrong with the baseband maybe? Which is what I was trying to search for yesterday. Was wondering if the current baseband for Android 11 is new or maybe it is the old one from Android 10?
Regardless, I can wholeheartedly say that Android 11 has basically shattered the signal strenght on this device to the point of making it useless. Now I can use it as a multimedia device... weeeheeeee.... Buy a premium device they say, it will be worth it, they say. Never had this issue on any of my Oneplus devices. Shame on Sony!
(btw my phone has the international software, not the HK one. using it on one single sim- XQ-AT-51).

The italian user told me now he's fine, the problem didn't came back.
Tomorrow I have a Switzerland holiday, I'm going to reset the phone to try to fix the problem.
Thanks for answering my question, it seems I'm not the only one with this problem. It's a pity there's no more official Sony forum to discuss these issues.

Please do let us know how you get going. I too wanted to perform a factory reset but I've postponed it in case I could find some answers on the internet.

The phone is now restoring the backup from Google but this evening I don't think I will make a single call.
Tomorrow at work I will stress it (usually I make 1h of calls everyday, using both SIMs), and give you the results. Cheers!

The situation is maybe worse than before.
I don't remember if is it possible to downgrade. Xperifirm? Still works with new phones?
Otherwise I have to use my old XZ Premium because I have so many issues at work.

The thing I noticed is that the call drops when switching network from 4G to 2G. Expecially on my Italian SIM, i have a weak 4G signal in my office (1-0 bars) but I have a full 4 bars 2G signal. Before this update when I start a call you can clearly see the signal bar going from 0-1 to full 4 meaning the phone switched to 2G. After this update it was impossible to place a call from my office on my italian SIM because it fails in that 4G/2G switch.
I put that SIM in "GSM only" and I had no issues in managing calls. It's unpractical but works.
The problem is worse on my Swiss SIM (the one I use for work) that has no 2G coverage, so I leave it in 5G/LTE/WCDMA/ecc ecc and hope the best. But I see some switch happens even there ranging from 0-1 to 3 bars (I think is 4G/3G switch. I don't have 5G or 2G coverage in my office). So I can't do anything to avoid the issue, that happens randomly but it's quite frustrating

(...)Same problem on HK. Does anyone think that the problem will be solved with an update? Sony flagship haha. The gsm signal was much weaker than the former P20pro before .... 178. Now ..... disaster. I think the only asset Remaining that you can read "network unavailable" on a 4K screen

So far mine seems much better after the latest update 58.1.A.5.222.
Here's hoping it was a temporary glitch.

Please try to use only one SIM until new updates.
I have the same issues but with only one it works fine.
Do we have any news about a new update so far ?
Have a good day!

Today the 58.1.A.5.222A update arrived, I tested the phone and seems to be OK, tomorrow I will test it harder during the workday.
PS: since two weeks I was using my old XZ Premium and the 1 II was resting in the drawer. So sad. I tried to flash another firmware but I had errors on Flashtool and newflasher. Nothing worked wtf.

After a working day in my office with many calls on both SIMs (a place where the problem was at its best as wrote before) I can confirm you the update completely solved the problem.
So thanks to everybody for the support, I hope you'll also be able to fix it with this update.

"Temporary glitch" un par di balle*: 3 weeks with my old XZ Premium, and the actual flagship "Xperia 1 II" in the drawer! And resets, backups, restores, tests, copying gigabytes of data from and to the phone, hours of trying to flash other firmwares and receiving only errors...

I got the same software number and my problem still persists. Thank you for updating the thread with your findings. Glad to hear yours is working now.

Hello everyone, I faced the same issue on my device after updating to the software version mentioned by author, I've fixed the issue by flashing .280 software for SEA customisation. Original one was HK. So, now I'm able to use my phone as usual. Hope this tip will help somewho. Good luck with your devices.
