[Q] USSD Command and Signal indicator bugs while in GSM Mode

Hi all,
I use the DR2 Global outside USA, in Europe and have some problem concerned with the USSD commands.
there are some important codes such as : #100* to check balance, #135* to buy some extra megabytes and #115* to take some extra talking time in credit.
When I enter a code the USSD code is running infinitely.
Do you have a same problem?
P.S.
There is no problem with the signal strength and network coverage, but the signal indicator is always at one point.
The phones software is run on verizon so the USSD codes will only recognize vzw codes such as #pmt and #data

Is there any way to fix these issues unofficially?
I also found that youtube app doesn't work on wi-fi.
i am in europe and have the same problem. i had a verizon touch pro2 before this, and it worked fine. not being able to check balance is a pain.
is there some way to get this to work? maybe via rooting the phone?
since it worked on the touch pro2, there must be a way to get it to work with this. as a global phone, these things should work.

weird network lock?

Hello
I just recently got the optimus 3d. its brilliant!
With the help of this forum I've managed to root and get Clockwork then install thais rom.

But i have just one issue.
My phone was locked to orange uk provider. when i bought the phone I had to call orange to have my phone 'activated'
only after i did that did the phone even receive a signal.
before that it just said emergency call only, or no signal.
now, i've unlocked the phone using a code. it now says no personalization when i check the lock menu.
but: when i insert another sim, vodaphone uk or 3 uk, it says emergency call only or no network.
whats going on?
please help...
thanks

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.

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?

[Q] No network nightmare

I bought an Galaxy S3 which was working fine, some time ago it fell and the screen was broken. I have been using it like that for over a month with no problems, I recently decided to change the broken screen and I took it to an authorized service provider repairs and it came back with a nice beautiful new screen. Problem is since then it does not connect to network it keeps on saying "not registered to network".
When connecting to Internet via wifi, it connects no problems, just that it does not connect to the Internet via sim card, but the sim card is working on other phones, what could be the problem. The imei number on the box and with *#06# is the same.
Your help is much appreciated.

Hi, the Access Point Name is entered and chosen as per the service provider's guidelines. However I am confused about the link which you said I must check because it is talking about M110s and I my query is about S3.
Please elaborate more.

don't use anything about M110S, but follow the guide to enter, APN, your phone number etc, and test your network connections, you need to check S3 forum http://forum.xda-developers.com/galaxy-s3-att or http://forum.xda-developers.com/sitesearch.php?q=galaxy s3 for any service codes and other settings specific to your carrier and model.
