Can't call when 3g is on

I can't make phone calls when 3g is on, with 2g is fine. I went back from miui to cm7 and finally to stock and still i can't call.
Do you think is possible that some hardware failure can lead to this?
More info: changed baseband too, i have this problem also if i change sim

If you changed the BB on your phone then why don't you revert to the previous one and check?

I would not exclude a problem with your carrier's network

I changed the baseband after this problem occured, I tried a different carrier (Vodafone, my carrier is TIM) and calling when 3g is on works
I'm gonna wait if they fix things

Maybe it could be obvious but...Did you try to change Ril by using getrill apk?
Non si sa mai ^_^

Si (Yes)
I tried changing Radio with different basebands but I have the same result, call ended immediately.
Now I'm on Cyanogen 9 and i'm keeping the ril that comes with it.
Calling with 3g works under Vodafone Italy, Tim doesn't.
I've found a post (in Italian) of one guy having the same problem with TIM one month ago, like me he was thinking that the phone was the problem but it wasn't. For this guy the problem got magically solved, probably a TIM fix.

Problem got solved automagically

I can't call when I have it on 2G only. Is that normal?

Thanks for the reply, spica. I have no idea what that is let alone how to do it. I'm new to this and just barely scratching the surface of this phone.

Hi Electroman!
In O2X you have Baseband and RIL. I believe you can think of these as the antenna drivers/firmware.
When you change a ROM usually this changes the RIL, then it is recommended that you download an app called GetRIL to download a RIL that matches your Baseband.
If you go to Settings -> About Phone you will be able to check what's the version of your baseband.
It is possible to change this baseband. I think the easiest way is by flashing a zip file using CWM, I've never done it because I haven't had any issues with calling or data network or whatever.
Some people claim that some basebands are better with some networks than others, so your call quality might improve if you change baseband, depending on what network provider you have, but then again, I haven't had any issues so I wouldn't know.

I'm almost sure that spica meant RIL, you can change it with an application called "GetRil" from the market, you need a phone with root available ( check the forums for that, it means you can run commands as you were the admin of your machine, unix style).
If that doesn't work i suggest two things: check other carriers with your phone, and check your sim card on other phones. So you can have an idea of what could be the problem.

Thanks again, LarsPT and gasgas. The thing is I haven't changed anything on the phone yet. Everything's still stock. I don't know but this could have something to do with the carrier I think. Maybe I'll give them a call.

It turns out Windmobile doesn't support 2G, and that's why the phone didn't show any signal.

[Q] Cannot send SMS and use a mobile internet... Can anyone help, please..?

Hello Streak masters,
please, I´ve got a question. I am at Maldives at the moment, for next year and something. I bought DS7 for very good price, everything is working great, it´s exactly what I wanted. But... DS was locked to T-Mobile (probably USA), but I asked Dell for sending me the unlock code, no problem, I´ve unlocked it.
And now is the problem. I cannot use the mobile internet & SMS with local SIM. Have installed 514 ROM, firstly for EU 3G, but there was a problem with modem installation, so then I realized I probably have the US 4G version (didn´t knew which one I have). It was OK, modem was installed, I am sucesfully logged into the local provider´s network, so the "cell unit" is working for sure. But I cannot send or receive SMS and what´s worse for me, cannot use the mobile internet, even if APN and all that stuff is well inputed and saved...
Does, please, anyone has any idea how to fix it? If it is even fixable at all...? Have to say that I am not newb in Android, but this is something I cannot solve by myself.. I would be really glad if anyone helps..
Thanks guys.

My first suggestion would be to flash back to Froyo and get it working and then upgrade from there

Hello,
thanks for your reply. I have tried to flash back to Froyo as recommended, but it´s still the same problem.. I am logged into the local network, GSM is working (to be accurate - only the loging into the network, SMS is still the same..), but mobile data not.. Even if I had everything turned on, the APN and all like this is OK (including screenshots), no... No way, it´s not working... Are there some any other ideas, please....?
Thanks a lot!

Guys....
Kill me, kill me right now, please... For four days I am solving this, reinstalling everything like an idiot and now I realized.... The damn Maldivians pre-paid cards has to be activated by making some call!! The SIM was not active all the time I was flashing, downloading, googling and all these things and it was simply not active... Because now I thought it´s very, very weird so I tried to put the SIM into my phone and it was not working either... Tried to make some call and it told me "this is your first call in our network.. your SIM has to be activated by calling to number bla bla bla..".. I made it... Everything´s working great now!!
The only thing I am really missing is the troll face on the SIM...
Anyway thanks a lot for interest, I am going to flash to the Honeycomb again.. For the last time!!
And apologize to moderators for pointless topic...

Maybe data is disabled? Try enabling it. Call your provider maybe something is wrong with them?

If you just got this new then simply take it back to the shop.

If you bought it over the internet...try flashing it with the right firmware for the location where you are at...Perhaps LGE Mobile Modem or whatever it is called, like iPhone's baseband has a problem connecting to the network provider, due to the configuration or firmware. But in most cases the problem is in KISS- keep it simple silly...and from my experience it is the problem with the network provider or SIM. Try the sim card in another 3G capable mobile phone if it works o another phone that it is not the sim card. After that reset to factory defaults your Optimus 4X and put in the card. Do not jailbrake-root it. Just test it with the sim card. If that does not help, upgrade or reflash the firmware. If you need assistance. mail me.
I hope it helps. Good luck.

We have a SIM tool kit that might helps. It's one of the apps.

SOLVED
1st i tried every thing i know
i called my carrier (Vodafone) and they stated that it is a Mobile phone problem after we tried all troubleshooting they suggested including adding the APN manually and etc. then i contacted LG middle east to help me and they couldnt help either
finally one of the Vodafone technical team called me and informed me that this is a known issue from their side and we configured the APN with different type and it worked

similar problem!!
I have a similar issue as the original poster.
I got my Optimus 4X HD about 2 months ago. Everything was working fine until a few weeks ago (I think it happened after an update I got)..my phone would just randomly loses connection to the network (no data, no text messaging, no calling). I tried turning airplane mode on and off and also tried to have the phone search for networks and they didn't work. The only solution is to reboot the phone. This is happening at least twice a day... I tried my sim on another phone and didn't have any issues so I don't think it's a carrier problem.
I also did a factory reset but problem still persists.
My phone's software version is LG-P880-V10d-OCT-16-2012
Kernel version 2.6.39.4
Baseband version L6260_MODEM_SIC_02.1216.01
Build number IML74K
Android version 4.0.3
Anyone have any idea how to fix this without rooting the phone???
Thanks in advance!

I have new mainboard replaced by warranty and 3G mobile data not working to, I've tried another carrier sim and there's no issues It must be truth that is something wrong with automatic APN settings...

[Q] Internet Connection Problem

Hi everybody.. I ordered a Droid 4 from the US (i'm in the UK) .. Setup giffgaff unltimited internet, however for some reason the connection isn't stable. Sometimes the connection will not connect for at least 3 hours. I have rooted and tried the AOPK, Avatar and Liquid ROMs, but its the same issue.
I have another Droid 4 running 4.0.4 and tested if it was a problem with the SIM card, but it worked fine.. No problems what-so-ever.
Any suggestions anyone?

I eventually gave up on giffgaff because of constantly dropped calls, and incoming calls that would go straight to voicemail. Found it a lot better on O2, which is odd given that both use the same network.
For your problem though, how is it if you use the stock ROM? all those 3 ROMs use custom kernels and I haven't had much luck with them on GSM. If it works on stock then you know the problem isn't the phone or the SIM at least.

I have noticed some of your old posts in the GiffGaff Community Forum.
FWIW, I've been using it in anger for just over a month, and can't say I've had any problems (apart from a short outage across the network, which is apparently quite rare).
Cheers,
Steve.

Yea the problem is persistent on the stock ROM too
Is there any way to calibrate the hardware?

Not that I know of, mine just worked.
Did you update to JB yet? I believe there were changes to the radio firmware included.
Other than that, I don't know. If you have an identical Droid 4 that does work with that SIM then the only explanation left would be faulty hardware

Yea it came originally with JB
Can you tell me how to downgrade to 4.0.4 if you don't mind please.

AFAIK - You can't downgrade, I'm afraid.
In the Network Mode, have you selected GSM/UMTS, or are you set to Global?
It does sound like you might have a hardware problem.

Steve.

Thanks everyone, but I found a solution ~ a very weird one...
I removed all the custom ROMs and safestrap and did a full factory reset on the stock ROM. Miraculously this did the trick strangely enough.

I'm going bonkers! I'll pay you 50 dollars to fix me!

I have a Note 4 Sm N910L from Korea. I live here in Japan at the moment. I bought the phone properly over Amazon and its new. I bought a data sim for it and it was working perfectly for about 7 weeks then one morning when I woke up there was no signal I have tried everything - updated from 444 to 501 then downgraded again UP and DOwn Maaany times. If I go near the Docomo store I can get connected again and it will stay connected for the 3km back to my home and then go off again when I reach home and not go back on - so I know the hardware still works ( I guess). It now just continually says Limited service or "your card is not authorised to use this network". Ive tried many other sims in the phone, none work.
If you can give me a step by step COMPLETE guide with links to any files I need to fix it, I'll pop 50 dollars in a paypal account the same day I can make my first skype call again!!! First person's info that actually does the job gets the money.
Love my phone and Im absolutely &%$'ed without it.
Hope you can help (the wife is out buying some rope and a straight-jacket as I type)

I loved the way you exposed your problem. I don't come here with a fix but only with few suggestions (so I don't deserve the 50 bucks) :
- check the pins of the sim slot
- check the back screws also and tighten them a little bit
- in network settings try to manually set provider and also choose only one mode (no auto 2g/3g/lte) preferably 2g only

It has happened to me with another phone. Turns out my SIM had failed, so it needed to be replaced. Sometimes it happens and it's quite easy to get a new one, so that would be the first thing I'd do if I were you. I hope you fix the problem soon!

Thanks but I tried the sim contacts I didnt notice any screws loose (except my own of course) I'll check (though not hopeful). I appreciate any suggestions.

Iridaki, thank you. I ve tried 4 other sims from my provider in it and they dont want to work either. I feel it is more a software problem as it was alright when i went to sleep one night and the totally banjacked when i woke up in the morning. Im not sure though, just a noob at all this.

Ah I see.
I think I know what's going on.
The N910L supports the following frequencies: GSM 900/1800/1900, UMTS 850/1900/2100 and LTE Band 1, 3, 5, 7.
Docomo don't use GSM at all, instead they use UMTS 800/1700/2100 and LTE Band 1, 9, 19, 21, 28.
Basically your phone is not designed for the Japanese market, as it only supports two of the eight frequencies used by Docomo. The reason you had signal and still have around their store is probably because there's a tower that supports the UMTS 2100 or LTE Band 1 frequency. So you either moved recently or perhaps you didn't but one of the nearby towers was switched to a different, unsupported by your phone, frequency.

In network settings , there should be a submenu where you can change it. You can also directly access it with long press on data connection icon in notification drawer

try this code in the dialer *#0011# whenever you have signal it helps you to identify which band you are connected with
After that you can buy a signal repeater that support that band and bring signal to your home since its not that far distance 3km from docomo store : )

Ive not moved recently, and my childrens phones on the same sim plan and provider works perfectly. Also no matter where I go I never get signal - except right outside doccomo shop. BUT phone worked perfectly for 7 weeks before with great signal. Something has changed regarding my phone I think. Maybe my phone got changed to different settings over the air or something.

Thanks for your help. I stlll feel the problem is something software or update based, maybe the modem has been changed somehow. Or another setting deep inside the phone.
Does flashing an update also flash a new modem and baseband?

Hi Iridaki,
Nope they have 2 old iphone 4 s' using the same data sim as me. (iijmio ((basically docomo)) ). Sorry about not being clear about that.
