Hi everyone,
I was using adfad666's KANG rom on new baseband using my old SIM card, but just moved to the US and got a T-Mobile prepaid SIM. I wasn't able to get signal using this card, though it was working on other mobile phones.
I thought it could be due to the new baseband, so I downgraded and tried a few roms for old baseband. Right now I'm with SlimGen, based on nightly, with no success. I also tried flashing aspee's baseband fix, but didn't get it working either.
Right now, automatic network searching says "Registered on network", though a warning sign appears on the tray saying "Selected network (T-Mobile) unavailable".
I've been reading this forums for a solution but I haven't been able to figure it out yet. Has anyone had this problem before?
What combination of baseband, ROM and patches should I try?
Thanks
EDIT: I'm also not able to find WIFI networks when scanning, though I'm not sure it's related.
It's possible it's the sim card, but you should first try updating the APN list: http://code.google.com/p/cyanogenmod/wiki/APNlist

I don't think there's a problem with the SIM, as it works on other mobiles.
I'm not sure about this, but aren't APN's for data access only? I don't have regular 2g/3g signal.
It seems you use T-Mobile in the US, what baseband/rom/patch combination are you using? I would like to take that out of the way first.
I'll try to set up the APN, nevertheless.
Thanks
Hi,
I have bought an used Samsung i9100 phone, that is like new and everything is working, except GSM network.
It seems that it can get a signal, and it identifies the networks of my country. But it cant connect to any of them. I have tried with different SIM cards.
Also, I tried flashing it with some ROMS to see if it solved something, also tried to use the EFS fixing tools available on XDA for I9100.
Also tried the EFS tool to unlock the phone, and it does give me a number to unlock it, but when I try to unlock it, it says that the operation was unsuccessfull.
Any ideas on what is happening ? I can see my IMEI properly on the Android about page.
Thanks
Post lacks information .
What firmware what baseband what network what area of use .
jje

do a factory reset and check
my other phone is a Samsung Galaxy S, which i have for more than a year.
I Flash it almost daily so i am not new to the works
I tried almost everything , kernel, modem , rom , unlocking , recovery of the EFS.
Dont know what to do more. It doesnt seem to be hardware related, because even signal strenght seems good.
It just says "emergency calls only" and cannot register to a network : says " unable to register, try again later".
That reads as possible IMEI problem. Or antenna even.

so you have a phone that shows strong signal but would not accept your sim ?
you cant register to network usually means that the phone is locked to a certain network and that your sim is not of that network
you can try calling emergency and if you get a connection hang up or tell the guys on the other side you made a mistake and apologize;
at least that way you know there is no problem with the antenna
but seeing your screenshots it appears that you do have UMTS? but no GSM?
this is weird and looks like the phone was locked to a certain network and then unlocked but not properly unlocked
again it was asked before: what country are you in?

When I first got the phone both slots worked. I've rooted the phone and installed some things and may have broke something. SIM2 works but the other slot is broken. I'm on tmobile too.
Feiteng GT-A7100 "Mobile Network Not Available"
Oh, gosh, I'm really stuck. Tried two SIM cards (redpocket/att and spot/t) and either works. Sim cards work with
dumber phones. Really like this phone (ie cool android hardware) other than it won't work as a phone.
I also have suspicion about the IMEI. Bought from everbuying.com. please email vjp2 panix com because I dialup and don't
have broadband. But I will try to get back to forum if someone replies. The Phone sees the SIM card (ie, knows name, and some addresses).
I don't know about all those extra setting with initials (some it has, others not).
But it says the SIM card is disconnected. Took it outside, closer to cel towers. Is it possible the sim cards are too cheap.
I only want talk. I've seen doc this phone is 4 bands, others say 2 bands

i have same problem
1) I noticed one of my sim slots (sim 1) was not detecting the sim card. Error message was something like "no sim card" which is different than "no service". In examining the sim slot, one of the gold pins in the slot was not making contact with the sim card. I took a small safety pin and bent the pin slightly up.
** NOTE ** be careful bending this pin up. If you use too much force, you can snap the pin off and then you would be totally screwed.
I then reinserted the sim card and the phone detected it since the pins were now making contact with the sim card.
2) Another thing I noticed is sometimes I get "no service" even though other times I would get 4 bars of signal strength at the same location. I went to settings and disabled the sim card. Waited about 10 seconds and then re-enabled my sim card. It then seemed to reconnect with the phone network.
My carrier is TMobile.

Guys I have a strange problem my razr wont connect to any of the data 2g or 3g only on custom roms like 4.4 Kitkat,Carbon rom etc . I flashed them on slot 1,2 even on stock slot but no luck.. I tried to change Baseband But It always failed So guys help me.....
Edit 11.12.2013:::
I fixed the problem partially..
I fixed the network mess It was bad radio which did this all I flashed ICS radio and now network works fine in all roms (Stock and Custom) BuT bo mobile data on any of them
Edit::::
Now Phone says NO SERVICE on both stock And custom rom but reads sim card contacts & SMS's...
I tried reflashing stock rom But no success. Help me guys...
2g/3g for many of the newer roms has been a problem with both the XT910 and XT912. I know with cyanogenmod 10.2 I'm still not able to connect to 2g/3g although LTE does work. With the newest release of cyanogenmod 11 though I do get 3g and LTE, although some people have been reporting they are not. Seems it's headed in the right direction. Give the latest CM11 build a shot and see if it works for you.

Is there any APN that saved in your network setting? If it doesn't, set it and save it by hand.

Can you make a call? Did you have paid the SIM card cost?
Sorry for my bad English
Yup my SIM is in contract and working on other phones I can make and receive calls but not on razr I get NO SERVICE message
Open the phone (or dialer, whatever you would like to call it) and Dial *#*#4636#*#* and go to Phone Information and tell us what the preferred network is.

Also:
What ROM did you get LTE Only on?
I learned that sometimes ROMs can mess up NV's. The only way of fixing this is to wipe everything and start fresh. And when you are flashing you cannot downgrade, it will fail every time. You may already know what I am telling you but just in case.
And what carrier are you with?

Now Same problem here but differnence i having this problem a sudden out of nowhere
its just been 13th month for my razr
never rooted or flashed ...
just updated to ICS from stock GB via usb data cable as update was in my country
I purchase a new microSIM & also did a data / factory rest from phone boot option ( u know from tht recovery option comes after rebooting in boot seq mode) to solve the problem but no positive result ... though i found one thing if u go to settings -> more -> mobile networks-> select network ... there you'll find 3 option
1) 2G only
2) 3G only
3) automatic default
well by 1st option works it given me range ... doesn't show no service or emergency calls but 2nd & 3rd option gives me same problem " NO SERVICE " or " EMERGENCY CALL "

Hi. I have XT910 for more than two years. After brought the phone from Australia to Hong Kong (use Hong Kong SIM card) and back to Australia (replace SIM card with Aus one), I have the same problem as you. Phone can make voice call, but no mobile data connection (3G, 2G).
Want to know if your problem is fixed or not?

Hi. Can you tell me how to fix the issue: no mobile data, and phone saying "Syncing SIM card contacts"? Thanks.
Hi,
the problem is:
I have a galaxy s3 (i9300) which i'm not able to unlock. The *#06# shows the correct IMEI, which is printed on the label behind the battery.
I've tried editing nv_data.bin, but can't seem to find the 00181460 address.
Galaxsim says "unable to load nv data"
The problems started about a month after i upgraded to 4.4.4 (back to n00t rom). One morning the phone just kept saysing 'unfortunately com.android.phone has stopped working'
I tried reflashing it, then tried using cm13.
Everything works fine, except there's now a sim lock on my phone..
running out of ideas, so thought maybe you guys have some fresh ones.
Thanks!
The standard repair-procedure is to flash firmware by Odin.
hello, i have the same problem. i tried lot of rom to solve the problem but it don't do anything. Also flashing firmware by Odin don't work. I'm happy that i'm not alone.
sorry for my bad english.
Hello, have you ever tried to flash the stock firmware with Odin ? For me, it did not solve the problem. If someone has a solution. ..:crying:

hi, the phone is network locked.
The only method that may work to unlock the phone for free is the regionlockaway app with root and an older modem.
Was the phone ever network unlocked ?
Thanks for your answer .
Yes, the phone was network unlocked when i bought it.
i tried regionlockaway, but it don't work.
I don't know what to do.
Not sure why the phone would relock. You tried installing a stock rom?
I tried this too, but it don't worked.
I tried to change The modem, the CSC, but nothing happens, the phone remains network locked.
Did you check to make sure the phone was network unlocked when you first got it?
Yes, it was unlocked.
no network after custom rom 4.4.4
Hi all!
I also have the same problem after a cutom Rom install, >no Network, Hope you be of help as i expect XDA always do :angel:
No network is not the same as bein network locked.
If the phone can't be unlocked for free, an unlock code must be purchased.

Changing to gsm only will only give the phone data access at edge speeds.
To return to stock, flash a rom from sammobile.com using Odin.

Did you confirm the phone was network unlocked when you first got it? The phone supports your carrier's radio frequencies? SIM card works in another phone?
You can use turbosim for unlock but i dont know what happen to you. Its only suggestion.
You can't network unlock an s3 for free if it has ever been updated to 4.3.
