Can't get my SIM card to work - Xperia Z3 Q&A, Help & Troubleshooting

Hello everyone, i have a sim-free Xperia Z3 (D6643)
However, i can't use it with my main carrier (strangely enough it came with that same carrier ROM/bloatware pre-installed). Signal pops up, mobile data connects and let me uses it just fine, but when i try to make calls/send texts or recieve those, it doesn't.
"Conditional call forwarding enabled" is the message i recieve, then it disconnects the call.
I'm using an alternative carrier that works just fine '-'
Question for the advanced users of flashtools (if this have something to do with my issue).
i flashed a already packed .tft ROM.
Read in a tutorial that i must exclud all the ".ta" files before make a .tft, analyzing the files before making a .tft i've foun a "SIM Lock.ta" let it out of the process and build my .tft just fine, but i haven't flashed this ROM because i'm not sure if i'll be able to use my usual carrier after the process.
Can anyone confirm that?
Right now i'm sitting at 23.4.A.1.232 for the D6603 model.
I know someone must know a way out for this :fingers-crossed:

Which network provider do you use? Try disabling ALL call forwarding through call settings.

Hello sir, i looked up to call forwarding settings and it's all disabled already... Yet, when i try to change any settings there a message says that network isn't responding, something like that.
My country has four major carriers, it just works properly with only one!!
Really strange, given the fact that we don't have carrier locked or exclusive devices plus all the things i've spotted in my first post (signal is full, 4g conneceted).

The activation bit is for the sim card, I have a phone locked to O2 and what happens is you register the sim with them and then they enable it to use their network which is why until then it will say no network.
It is also the reason why if you put any other sim in the phone, and that sim has not yet been used to make calls, you get the same error.
As for the personalisation message on the unlock menu, I am unsure what you mean by the lock menu. I assume you mean the screen you see before you unlock your phone to use it each time, and did a search on google which produced no results but I would guess that if you are using a custom rom the message means you either have not personalised your screen or that the option is there to personalise it but has not been used.

unlock menu - where you enter the network unlock code.
i'm trying to use my 3 uk sim, its been on contract for over 2 years.
I know that a lot of unlocked phones wont work with 3, if you google 3 unlock you will find a lot of people have problems and some unlock companies even specify they wont unlock to 3 network but if it does the same with non 3 cards or only works with one operator perhaps the unlock was only partial?
I did a search for pedsonalisation and all I found were various unlock sites saying that a sucessful unlock needs you to have a personalisation menu.
My previous android phone had a device lock and a sim lock, could it be your unlock has only partially worked? Is it only one provider whose network you can access?

you're being really helpful so i give thanks.
i have tried o2 and vodafone sims in the phone also but to no avail... always says emergency only or no network, with both showing no signal.
would flashing the original orange rom back then retrying the lock code help? as of right now when i go to the unlock menu and click network lock it prompts a message stating my phone has no personalization.
sorry missed out a little bit of info.
the only network that works is orange, it gets full signal and works perfect, but i'd really like to use my contract sim instead of pay as you go extra on orange.
I've done some more searching and found that on a lot of phones that personalisation message means the phone unlock has failed and that after a successful unlock it should say something like "network lock has been personalised".
You do only get a certain number of tries so don't enter the code over and over, if you are sure you entered it correctly it means the code you got just didn't work (I had that when unlocking my previous LG and had to buy a code from somewhere else as the first one didn't work at all).
I am not recommending this site, it's just one that explained how to unlock so am posting a link in case it helps, but the site says you need to enter two codes on an Optimus 3D. One is for network lock and one for service provider lock, I know that some people on the xda forums have unlocked their phones so I hope they will jump in and help solve your problem as really all I can do is google for the bits I am unsure of but it would seem your code did not work, or that you need two codes and only had one.

just wondering if i could post a video link here to show how it happens, if not, mods can you delete this link:
http://videobam.com/YqMQH
might need to tilt head/computer screen
that was with orange sim, without orange sim it shows no signal and no network... its running thais rom.
heres a video of it using another sim.
when i start the phone with other sim, it prompts whether i'd like to use mobile data or not, but no connection!

Well having watched your videos I can clear up something, I think.
I had searched for terms based around "no personalisation available" which means your code did not work but searching for the actual message in the video "your phone is not personalised" produced completely different results.
That specific message means the option you are clicking on is not locked (not personalised by your provider) at least according to various pages I have found including a few on other well known Android forums so if that's correct your unlock did actually work and that is why the message appears.
The page at http://www.cpkb.org/wiki/LG_enter_NCK_code also mentions this code and its cause.
If the other sims you try offer you data or mobile but do not connect, yet you can make calls, then you need to set up your apn for that provider. The apn tells your phone how to connect to your provider.
This is really easy to do but you will need a free app called Apn global from the android market at https://market.android.com/details?id=osatek.apn.global obviously you need it on your device which can be done in various ways, possibly easiest if you can connect via wifi and go to the market.
Install and run it, pick the name of your provider (the provider whose sim you wish to use) and it will create the mms and internet settings for you. Then mobile data should work.
Alternatively if you have an android phone which you already use that sim on, install to that phone and choose the apps backup option which will backup your exact settings to sd card so you can import them to another android phone.
If you have other providers apns on there you will probably need to tell the phone to use your new settings. Simply go to your phones settings menu, find the wireless settings option and click it then scroll down the screen to "mobile networks" and click that. Then click "Access point names" and choose the desired provider. I have three on my phone and you can always revert to any other settings if you change provider later.
The apn app is very useful, I have used it on a few phones, it has a large list of providers worldwide so you should find your choice of provider there and hopefully that will solve your problem.
Dave
Thanks for the reply dave, but I have yet more bad news sadly.
I can't actually make calls, as shown in the second video it shows no network/emergency calls only.
It's hard to believe no-one else has this issue.
I have owned lots of android in the past(started with g1, then hero, then jumped to zte blade then galaxy 1, now this) none of them posed any difficulty removing network lock.
Its such a strange problem that a search of this forum shows at least one other person had this issue but no-one could help.
Sorry if this sounds stupid but have you gone into the settings menu on your phone (Settings/Wireless and Networks/Mobile Networks/) and chosen the "select your network provider" option?
There you can force your phone to use a specific network provider.

I have with error "Unable to connect to this network at this time. Please try again later."
I don't think I can help, though I did some more googling and on the cyanogen mod forums someone posted a similar problem....
I've been using the nightly builds of CM7 since they came out and have had no network problems. I then installed version 7.0 [stable] when it came out, and just yesterday I installed version 7.0.3 [stable].
I have had no signal since, and whenever I try and select my network from the Settings > Wireless & Networks > Mobile Networks > Network Operators, it comes up saying "Unable to connect to this network at this time. Please try again later.".
It is nothing to do with my network provider, as my brother's phone works fine and he is on the same network as me.
I am on Three Mobile.
Please help!
RESOLVED: I just wiped all userdata and reflashed CM 7.0.3, I'm a very impatient person

If you fail to get a solution this option may help but probably best as a last resort. One thing I did notice when watching your second video is that you have the wireless on, this will stop your phone connecting to any providers mobile data so at least as far as mobile data goes you won't be able to use it when connected to wifi and would have to switch wifi off in order to test the mobile data connection.
Also I know that on my O3D my wireless sometimes seems to cause my phone signal to switch off with the little x. I doubt that is the cause of your problem but may be worth trying to connect with no wifi.

I'm going to try reinstall the original orange rom that came with it and downgrade baseband, if that fails to work after a full reinstall using lgflashtool I'll have to try get another phone.
thanks for all your help dave, i really appreciate it!
A popular unlock site says the only steps needed to unlock to any network are...
1. Input a non accepted simcard
2. Phone will display enter “Sim network unlock PIN” or “Enter Network Unlock Code”
3. Input the 8 or 16 digit unlock code that was emailed to you
4. Phone is unlocked!
If you did this, which you obviously have, your phone is unlocked and the problem must be something else but if you're going to flash a copy of the orange rom you might want to check first with one of the more knowledgeable users here that the rom won't replace some of the locks you already removed.
I checked around and from what I have found it should be as easy as put the new providers apn on your phone, select their settings from mobile networks menu for provider and also mobile data and that should work.
One orange customer who unlocked a different model android phone found that all they had to do was flash the radio only (not the rom), not sure how you do that but there are probably guides on xda.
Dave
I flashed the original orange rom and after flashing the froyo basrband it suddenly worked. Flashed gb again and it still worked, seems i just hsd to reflash basebsnd/radio like you said.
Thank you so much

Hi pauliebb,
I have the same problem that you had. I bought a used unlock O3D vodafone ES to gift to my brother, he lives in south america and he told me that the mobile does not recognize his SIM. What did you exactly do you did to reflash the baseband firmware???
I supposed thet the mobile is unlock because it shows the same message when enter to the unlock options "phone is not personalised"
Regards
the same problem
i have the same problem, i have phone from plus gsm poland, phone is not personalizet but read only sim card from plus, diffrent card not read and show info no sim card, help me how resolve this problem?

Note Edge 915T Wont let me call while on LTE - Help needed :(

Hello all..
I have this issue with my Note Edge 915T (T-Mobile Variant). It is unlocked and I use it in Venezuela with Digitel (LTE BAND 3: 1800) and the phone DOES connect to LTE with no issues (I get the 4G/LTE icon), and I can browse with no problems, but no one can call me, nor can I make any calls or text. In other phones, when I call, data drops and I can call and when I finish, data comes back up. HEre, LTE stays up and my call does not get through. Then after some tries, it drops to EDGE and won't pick up LTE until I reboot or something.
If I try a different operator, it goes to HDSPA (3.5G) and I get voice and data (data drops while calling, but it ir normal), but I want to use my operator with LTE.
Im running MM and I deactivated VoLTE as my carrier does not support it, but is there something else I'm missing?
This may sound stupid, but have you set your APNs? You can also try resetting your network. Dial ##72786#. Also Does your carrier require any certain apps. Example FreedomPop requires a specific app for getting/making calls, as they are mainly VOIP MVNO...

Hi! thank you but yes, the APNs are perfect, I can use Data, the issue is that I cant call as the data signal stays in 4G/LTE and with my carrier, when calling, it drops data signal and it calls, here I can't. Im starting to think it has to do with CSC being with TMO, and I should use another one either from my country or a general One (BTU) for example. Will try to flash a rom from a different carrier to see if it works.
The only other option might be *#BAND# (2263),which could be dangerous, if you do not note original settings. Sometimes a complete ODIN can restore.
I normally use Nova Launcher - Widget- Activities- Somewhere under phone or settings. Shortcut Called PhoneInfo or DeviceInfo, which is much safer&consistently works! The app w/ same name no longer works. It took me forever & I always export my desktop, so I have that shortcut. The last option is an app called Samsung Phone Info+, but is paid or free if u know.... I really hate paid apps. It has under menu secret codes as well.

[Help] Want to stop receiving phone calls while USB tethering

I hope this hasn't been answered before but searching through these forums with the keyword "tether" and also searching google I have found no solutions
I am tethering my phone's data connection to my laptop, but every time I receive a phone call my connection gets interrupted. I am using my phone's data connection because the wifi here is garbage cause the family is constantly streaming videos.
So what I want is a way to stop receiving calls or even better is my data connection not to be interrupted while receiving calls. Either way is a solution for me.
As an avid gamer, even a few seconds of disconnect feels like a lifetime. Hope someone can help! :good:
Check your operator if it support VoLTE. If yes and your phone software was modified by operator than you just need to activate VoLTE in data settings and you will be able to transfer data during calls.

I'm sorry but what? Check my operator? I'm not quite sure what that means. I checked everywhere in settings and could not find something that resembled VoLTE. A more noob friendly walk through would help.
Edit: Looked around and found out that my phone doesn't have that option where some galaxy S8+ do have the option. How do I enable seeing it?

still having a really bad time over here guys help ?
ValueDD Did you enabled VoLte ? Without it data interruption during call is completely normal. If you are on 4G standard when incoming data call is detected then you phone need to switch to 2G to handle it and in this standard other data than vice call cannot be transmitted . Because of that couple years ago VoLte standard was developed which allows to handle calls in 4G technology. For VoLte working it need to be enabled on your phone which need to be supported by our carrier as a VoLte standard itself...If your phone is unsupported than you phone wouldn’t have voice over LTE switch present in the system.

Asus Zenfone 6Z wifi calling activation

Here are the steps to activate Jio wifi calling on Asus 6Z. You need to enter code *#*#3642623344#*#* and this will activate special menu under Network settings. You need to deactivate Volte/Enhanced calling switch first then activate wifi calling and after getting wifi calling symbol again reactivate Volte switch. You need to repeat this after every restart of phone.

That's how these cheat code works. It does the job in background. After entering, it should just go back to dialer without having press to call button. Then, check in settings.
There is wifi call in the settings, but there is no icon in the status bar after I turn it on. I follow the video

Does your operator support wifi calling? In India this method works perfectly
There are Wifi calling functions in the settings, and the operations described in the videos and posts are also followed. There is no wifi call icon, and there is no attempt to call. Is it not supported in the Hong Kong version? Although this function is available, it is invalid.
Wifi calling already enabled on this Android Q, no need to d this..I am already using it
dial *#*#4636#*#* you will easily get WiFi enabled service
Does it really work though? After doing this, it refuses to make a call if you say wifi calling only which makes me think it still needs the mobile carrier to have a signal for calls.
Service is t-mobile fyi.
It is working flawlessly in India on Jio network. I have demonstrated in Video also

It only works in India (maybe some other places?). They don't seem to care about the US.
According to one of the mods on the Zenfone forum:
"When it comes to features like VoWiFi, VoLTE and so on. It's about testing, paying fees and signing contracts."
I don't think they care enough about the US (they don't really push the phone here) to pay the money. Don't hold your breath. Probably need to go custom ROM.
Custom ROMs didn't allow it to work on TMobile either. Glad some can actually use it though.
Volte doesn't work in the USA

What apps or settings might interfere with carrier network connections?

My carrier-branded, SIM-unlocked phone, when starting up normally, will - at first - not make or receive voice calls with the APN settings for the MVNO SIM card I have (mobile data works right away). I need to manually switch to the APN settings that came preinstalled with the phone (and which contain no settings except for the APN address of the carrier that I bought the phone from), then switch back to the correct APN. Then voice calls work. If I boot up in safe mode, this dance isn't necessary. Which would suggest that there might be some app or setting on the phone that interferes somehow with the proper functioning of the voice call function.
Not sure if this is related but I also note that the VoLTE setting is always greyed out (although it's set to "On") and I never see the VoLTE icon in my status bar though with the same SIM card, I see it every time I make calls on my other phone from the same manufacturer (Samsung).
I have posted the specifics of my phone in a previous post in the subforum for that model, see below. Any suggestions on how to trouble-shoot this?
