[Q] Mobile network not available..?

Hello, I bought of a friend a Samsung galaxy s and he said it needs only unlocking,so i "think" i unlocked it successfully.Was putting a O2 Simcard in and in applications i was having then the o2 SIM Toolkit.
But when i tried to make an phonecall, he tells me "Mobile Network not available",so i went to settings and wireless and network and tried to choose an network operator but he tells me then " Unable to connect to this network at this time.Please try again later."
What can I do?

Did you check the APNs?

Please first check if your IMEI is intact. If it is, flash a different MODEM and see if it works. If it's not, flash a fresh ROM using ODIN and that should hopefully restore your efs.

At first thanks for the reply, but now what is a APN? And how do i know if my IMEI is intact?
Sry,am a newbie

For you IMEI you should check your original SGS Box's sticker. There should be you IMEI number printed on. If you dial *#06# you should be able to read your IMEI. --> Look if it is the same as on your box
for apn settings. Apn is your connection settings, how your phone connects with the providers network. you have to check your mobile network settings if these are correct.

So, the IMEI nr is different then on the sticker,and the apn wasnt ticked,so I ticked the O2 and tried but still no mobile network.
Then i need to flash if I'm right?
I was already looking a bit around here about roms etc. But there are quite a few out there,so when you say to flash a fresh rom,which actually do I need to use?
Thank you

Hi again,
because the imei wasn't the same, I flashed it with a new rom (actually two different ones)
But still after both flashes I still don't got my old imei and still no mobile network available. After the one flash with I9000XXJPU he didn't said anymore no mobile network available,instead he said no data network available.
It would be nice if somebody would have some advice or help.
Thanks

hey! don't panic, i have had the the same problem
just download darky's resurrection edition in the development section and flash it. it should bring you back to froyo 2.2.1 and should also restore your imei properly. after this procedure you are free to flash any rom you want

Flash back to 2.2.1
Check imei
Continue on..
Also the problem you had when flashed JPU sounds like you didnt have your APNs correct..thats why the "no data network available"

No Network
Hi!
I have the same problem.
Network is fine (i switched the SIM-Card into different phones), but my SGS GT I-9000 does not connect / find to any network.
I am running Darky`s ROM 4.0.4 v11.0 Black Edition with 3.0.17-Semaphore_ICS_1.2.5s.
Also, the phone says on screen the name of my network provider (COSMOTE), but no signal.
What now?

Flash one more time with Odin version of 2.3.5 XXJVS or JVT De-Odexed and it should work, don't worry its not gonna explode, these processes are always reversible!
I have seen more myriad cases that the installation was not a success the first time and they have to do it one more time over the first installation!
If this is helpful just hit the thanks button, alright?

Hello Andre
Congrats on the new phone!
You don't need to re-flash anything (Well... maybe 2.3.5 JVT anyway ). What you need to do is look up your mobile carrier's apn settings on the net. You will have to enter them manually and you will have your mobile data back.
Settings>Wireless & Network>Mobile networks>Access Point Names.
Follow that path, and that is where you will have to enter the carrier settings for internet and mms.

Tanks m8 but i still can entry to the net :S .... i will try with the version 2.3.5

Dude,
I think you need configure your APN Settings for your GSM Provider

First you set date and time and country reboot phone.
or
You call your provide network say not working data they see you settings and help.

Does it work now? Have you checked you have the correct csc code. The easiest way maybe to download nitrality, and check which one you have and see if it is correct by looking it up either on google or on here. If you do need to change it, it will factory reset your phone (but its a new phone so that shouldn't be a problem )
You can also check your csc code by dialling this *#272*your imei number#

Maybe your APN is wrong.

To check APN
To check APN's you go to settings and goto wireless and networks then mobile networks and then access point names and your carrier should be setup in there if its not go here to find the settings http://ausdroid.net/apns/

A little help from a noob
Well, I've gotta start somewhere. Maybe someone can help push this out from here so more can see it, but I may have a fix that could help. I've have an Evo 4g Supersonic on CM7.2 that somehow lost its 3g data connectivity. Searching searching for APN settings, numerous calls and chats to Sprint (no help), it was finally a call to HTC that helped.
From CM7, I couldn't find a way to update my PRL and Profile. Essentially, those options are "Sense" and not on CM7, so I had to find a way to get to those settings.
Basically, I flashed a Stock ROM (5.07.651.1_Supersonic_Stock_Rooted_CPTB_v2.3-DEODEXED), updated PRL and Profile, then flashed back to my CM7 I backed up before I started this journey.
Works. All is well now. Hope this helps. I'll check back to answer questions if I can be of any more help.
Now, a disclaimer, I'm newish and/or limited in my understanding of how to toy with the Android system, so...as I've noted on many forums across the net, some people will push a "duh, why didn't you know that, noob" kind of approach. Well, go for it, but realize it's rare someone will get on a bike and know how to ride it. We all started somewhere. With that, please feel free to abbreviate, fix, and repost what I have here so this info gets out to the world. This is my FIRST post, so it's likely rife with mistakes. The intention is good.

well .... this is the same scenario with my GT-S5570i ...
Mobile data connection on my GT-S5570i with GB2.3.6 is working fine ...
but after upgraded to Jellyblast then MDC is not working ....
what I did was the change the CSC code ...
To change CSC code on your mobile ...
check your IMEI number by dial *#06# and write it down ...
(u can also check by go to setting > About phone > Status > IMEI )
after that dial *#272*YourIMEINumber# and you will see the multi CSC screen ... (if your ROM support multi CSC)
choose your country CSC and tap on install ....
phone will install and reboot itself ....
after that try your MDC again ....
hope that it should work ....

[Q] S i9000 unable to connect to network

Hi, I'm hoping you can help. Total noob so please bear with me.
I got a Si9000, it says it is unlocked.
When putting in sim card I got data network not available error.
Installed S1_Odin_20100512.pit
In PDA option I put in code_i9000XXJVS_CL565837_REV03_USER_LOW_SHIP.tar
For phone option I put in modem_i9000XXJVS_REV_00_CL1059471.tar
For CSC option I put in GT-i9000-CSC-MULTI-OXAJVS.tar
After I was told to type in *2767*3855# to reset phone.
Phone has been updated to 2.3.5, but now getting not able to connect to network error. It says mobile network unavailable. Any Ideas?
Thanks

have you checked that you have the correct settings for the network you want to use and also check that you have a valid IMEI number

Yes, the phone is shows the network, but when you try to select it, it says unable to connect.
I just checked there, and the IMEI number is valid

The files are in the right place, so nothing wrong there. Is wifi working?

Yep, but wifi is the only thing thats working. No data or mobile network, no GPRS either

Which network are you with and what settings do you have in APN ?
Would recommend ...flashing Rom and Re-Rooting*

I am wondering if it's just something in the connection settings. When I went to Japan last year I had to fiddle with something in the settings before I could pick up signals. It was in mobile networks. I think you can select cdma or something like that.

Im with Go Conquer in Ireland, actually brought the phone to a shop to be unlocked, as it was Vodafone, but they said it already was unlocked. They have their settings up on their website so I have entered them.
I'm going to try putting it back to its original settings again, and rooting it again, do you think that might be it? Ill also try the cdma settings.
Thanks to you both

Follow my Guide below to flash Rom and then Root it
Why did you go to a shop to unlocked it ...theres apps on here free??

Did you manage to get it right again? I'm having the same issue as you do. I did a factory reset with cwm and now when I enter the sim card it doesnt connect to network or 3g. Wifi does work. I am on original rom 2.3.5 and I dont know what to do. I tried a other sim and that didnt work either. Please advice. Thank you.

Are you sure to have flashed ROM with proper CSC bandwidth for the region where you live?

Hi,
Thank you all for replying! For some unknown reason the phone works. I left it a day off and then I powered it up again and it worked. So I dont know how but thank you guys for replying!
Grtz,

settings/wireless and networks and then select more, then go to mobile networks and now you will see APN's, does it show the right apns?

i dont know the history of the phone and wondered if it had been black listed but i checked the imei number and its not.

hmm..theres a radio button next to o2 pay and go i checked it and went into another menu..most of the list says not set...

oh they are set..i pressed the + button..no i pressed the pay go name and it shows the settings but dont know if they are right or wrong

if im right there is also an option to reset the apn settings to default, you could try that also
