Hello, I think my phone is simlocked. I bought my nexus s from carphonewarhouse here in the UK on vodafone contract.
My vodafone simcard works fine but if I put another carrier simcard in, it says no service but I have full/good reception. Also it does not ask for a simlock unlock code!
WHen I manually choose the network it says, unable to connect to the network.
I have changed roms etc.. to stock and even tried 2.3.2 radio and the 2 new 2.3.3 radios!
Please help? I thought all nexus s works with any network?
all Nexus comes sim unlocked
if you try another network, make sure it has the correct frequencies supported
Did you try radios meant for the other carrier's network?

I couldn't find them, do u know where I can get it from? I tried all network Sims in the UK, none work except vodafone.
You probably have manually selected Vodafone in the past and the phone tries to connect to Vodafone. You have to go into settings and select 'automatic network selection' or manually select another network.
Am I the only one stoked by the timestamp on the op <.< 1337

I've tried that, it says "cannot connect to the network"
Check your APN settings (Settings, Wirelss & network, mobile networks, APN).
You might have success by manually adding the correct ones for the network you're attempting to connect to.
Are you inserting ACTIVATED SIM cards? Also does making voice calls work on it? If voice works and data doesn't, it's your APN settings that need adjustments.

I have Samsung Galaxy S 4G with T-Mobile in San Francisco.
Whenever I go to an area without T-Mobile signal, the phone connects to AT&T. I called T-Mobile and they said that's because T-Mobile has roaming agreement with AT&T so my phone would connect.
The problem is, when my phone connects to AT&T, I can't make any calls. It says the phone's not registered. T-mobile says that's because I'm in an area that has T-Mobile coverage.
You'd think that the phone would be smart enough to figure out that only emergency calls can be made (which is what BlackBerry does and shows SOS sign). The real problem for me is that, I have WiFi calling enabled with cellular preference, and when I'm in the basement of my office building where there is no T-Mobile signal (but there is WiFi signal), my phone thinks it has cellular signal so it doesn't activate WiFi calling, yet no phone calls are coming in b/c it's not registered to AT&T's cellular network.
Is there a way for me to force my phone to only connect to T-Mobile? I know there isn't on the regular settings menu, but perhaps experts could tell me how to do so using those star-sharp keys listed here (http://forum.xda-developers.com/showthread.php?t=842134)?
Thank you!
Set wifi preferred instead of cellular.

Unfortunately, that doesn't work for me because I move around a lot, and Android WiFi calling feature doesn't have handover.
There's got to be a way to prevent this phone from connecting to AT&T at a low level somehow, no?
How do I do that? Have checked the manual but can't find location where explains how to select wi-fi preferred instead of cellular. Your kind advise will be appreciated
Open WiFi Calling and select settings. You'll see Preference. Select Cellular Preferred.
I think in setting then wireless and network, then mobile networks then network operators click the default settings.... select manual and wait for the carrier to pop up.
Will this solve your problem?

yep manual is exactly what OP should do.
if the settings for network operators are set to manual then u select the network u want and it sticks unless u manually select a different network provider. u are in select automatically mode so the phone can switch all on its own. this should solve your problem as other people have already mentioned
I have tried this many times and works as long you don't turn the phone off. After I forced the phone to manually select T-Mobile I checked many times the default setting and it remained in manual until the phone was turned off. When I switched it back on it was again in automatic mode and switching to ATT when signal is low.
Is there a way to prevent this? If not, well , first thing when phone is on in the morning is to check default setting.
5/24 I finally gave up and sold the phone. Samsung says they have not received any claims regarding this issue eventhough you see it frequently in the forums. I returned back to my HTC HD2 and will wait for the G2.
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.
amazing speed increase.
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
after a search it seems other people also have this issue with no reply.

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"

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?
Hi,
I have a galaxy skyrocket i727 from AT&T with last Gingerbread firmware(2.3.6 from at&t).Now i am in india.Recently i did a factory reset and now i have lost data connectivity(though i get full signal and can do calls or messages).
Even before i used to select frequency bands manually to swap between 2g-3g by dialling *#*#197328640#*#* and i used to get data fine.As there is no such option of selecting 'gsm only' or "wcdma preffered/gsm" in wireless&networks menu of the AT&T Firmware.
So the main question is if i put the unofficial ICS ROM like AOKP or UCALC4 than will i get this 2G to 3G selection in settings?Will the phone select indian frequency bands automatically?
thanks!
You may have lost your apn and that's why you can't get data, check under settings mobile network apn if there is anything there(I think that's how it goes in GB) if there isn't check your provider's site or call them and ask how you should configure it.
About your second question, it depends on what rom you will flash, some support it and some don't.

My APN is ok.I requested new apn after deleting older ones and even did a manual "Add new apn" perfectly.Thats why i am asking this question ,because there is no reason for getting "no data".Everything is perfect except that there is no "E" or "H" symbol with up-down arrows beside the network strength bars!
Stupid question but did you enable data?

yeah dude!Obviously!
enabled - disabled it several times!rebooted after selecting apn etc etc But no good
Well sometimes we ignore the obvious so I had to ask. Check your apn again to be sure, make sure the internet apn and not mms apn is checked if you have 2, and it's defined as internet or internet+mms in case of one combined apn.
If this wont fix it something must have happened in the factory reset and you should try upgrading to ICS and see if it still works.
Hey.. BTW I have a question for you , how did you unlock your phone yo use it in India ? I know there are unlock codes, just curious if you got it from at&t or you had to go the eBay way ?

- You need to be SIM Unlocked and have a RAT Unlocked Radio (HINT: Roger I-727R radios)
and
- You need a ROM to support those, if you using TouchWiz I have supported this always from the beg. im my
ROM (see my sig.)
And I do travel there once a quarter, no issues for me. I have an IDEA Card and it works perfect, even ROAMING to 3G where IDEA piggy backs on other providers..

Thanks for the reply.I just flashed the sk8erwitskil,s Latest Cyanogenmod 9 with UCLF6 libs just to check if i was able to switch radios,but right now i am in "2G/gsm only" area.Data is working fine,but cannot turn on wifi...it keeps saying "turning on".
My phone is sure sim-unlocked on idea network,and on UCLF6 Modem(is this thing same as a "radio"?).Initially i was on stock at&t GB firmware.Btw ,which place in india do u travel?
If wifi error persists i will flash EMBRYO Rom
Hello there, i just got this phone 3 weeks ago and since i have wifi i didnt test the 3g conection before. i activated a data pack and i just realized that my 3g doesnt come on at all. the screen shows 4g left side of the signal strengh but it doesnt work at all. i got at&t version. i confirmed with my carrier and i did activate data, they even helped me to set up the apn but is still not working. can you helpe me? thanks!
PD: they said they couldnt have done more because they dont support that type of device
Does it say 4G or 4G LTE? The at&t icons are a bit different I'd you're not used to them.
4G = hspa
4G LTE = LTE
So if you're getting the 4G icon you are actually getting 3G hspa speeds.
Sent from my Evita
If another carrier besides AT&T, you will need to find the APN settings for your carrier and manually enter it into Settings>Mobile network settings>Access point names. Select "New APN" and enter the correct settings for your manufacturer.
The 4G icon simply means a network is present, it doesn't mean you are connected to it.
thank you for helping people. whel actualy i wouldnt mind getting 3g network access, the point is that i dont have internet access at all. i called my carrier (Claro - El salvador) and they helped me to set up the apt but is still not working. i was wondering if there is something else i could try to fix this
nevermind, i finally fixed it

sorry. well, first i did master reset, once done i set up an apn (carrier provides you with this info), then went to mobile network > network operators > select automatically. once the device found the "CLARO" network i turned data on and got internet service.

I'm guessing you either had not entered the APN info exactly correctly the first time. Or also, after entering the APN you actually have to select it as the "active" one on the list of APNs (making sure it has the colored dot next to it). Maybe it did need a factory reset, but this shouldn't be necessary just to change APN.
Happy you got it figured out.
