left the phone on the sim unlock screen for an hour and a half (but screen was black as it was asleep).. forgot to put code in.. 11 percent of battery was used up ... if you look at phone battery usage it shows cell standby (trying to get signal) as top user...
The phone shouldnt be trying to get the signal anyway till i put in my unlock code..
You need network for emergency calls
sounds normal to me
i second what freakyzoidberg said
even if you turn on the phone has SIM locked and you are using a SIM card from another company, you can still make 911 calls on most phones
except that it never gets network.. if that was the case it would have network signal.. if you look at the top bar it shows no network.. it either should acquire the network so you can make emergency call or stop trying to get it (using up battery) till you push the emergency button.. i dont think this functionality works anway.. i will test because without simm card how does it know which network to acquire?

i think the phone recieves all available networks before it asks for the SIM-pincode... after that it needs time for connecting to your SIM-provider network etc. .. If you have no SIM or a locked SIM then only emergency call is possible because it is the only number that is present in any network. The phone will then use the first available network to connect...
Can any one tell me why my TAB will not recogize my valid, working SIM card from my other phone? Perhaps some setting on the TAB has to be changed?
Thanks for any info.
dude
dude i dont know. i tried the same thing. i have tmobile usa and the Galaxy Tab, along with my HTC HD2. tried the swap, no dice. saw my phone number, but would not txt, call, or receive calls. no data either.
My TAB doesn't even recognize when that the SIM is plugged in .
It keeps saying: "Please insert a SIM card". "Emergecy Calls Only".
This is going to sound really dumb but try shoving the SIM card in further. With certain brands of SIM you can get a "click" without the SIM being correctly seated in the tab. The tab will reboot if you insert a sim properly while it is on.
Problem solved! I thought that it was unlocked, but it wasn't. Followed Rothammer advise on unlocking and that worked like a charm.

I have the same problem with my SIM not being recognized. I have an AT&T Tab; unlocked [verified network is unlocked]; flashed with Rotohammer's most recent JME-Full; Baseband is I9000UGJK3; IMEI is OK; and Mobile Network is HSDPA. Interestingly, the signal strenth shows full bars, but does not recognize SIM and does not allow me to enter the Mobile Networks [grayed out] to change anything. I've tried every fix from every thread I can read here. Any thoughts anyone to get this to use voice and data?
Flash the Bell i900 modem for at&t tabs.
I've been having this problem for a few days now. Whenever I try to make a call, it gives me the message, "Mobile Network Not Available." I am able to connect to Wi-Fi without a problem but I cannot make or receive phone calls or text messages - only "EMERGENCY CALLS ONLY" I thought it was because I had weak signal at home so I traveled somewhere else but still, with little success.
I've tried everything I can think of. I have:
- Factory reset it (many many times)
- Removed the SIM card and put-it-back-in trick
- Put my SIM card onto another phone and worked just fine
- Airplane Mode On>Turn off phone> Turn back on phone> Turn off Airplane mode
- Create a new APN under T-mobile settings
- Turned the Radio off and back on again
- Went to Settings>More>Mobile networks>Network operators>T-Mobile and it gives me "Your SIM card does not allow a connection to this network." and sometimes, "Cannot connect to this network, please try again later"
- Turned on "Use only 2G Networks"
- Turned on "Data Enabled"
- Turned on and off "Data Roaming"
- In the Setting>About Phone>Status, it says,
"Network: Unknown"
"Mobile Network Type: UNKNOWN:0"
"Mobile Network State: Disconnected"
I have tried all of this and I am still unable to make or receive calls and text messages. Anyone, please help me !!
Sounds like you need a new Sim card. If you tried putting the Sim card in another phone and it doesn't work, then most likely it's a Sim card issue. Order one online or head over to a T-Mobile store and they should give you one for free.

No, when I put my SIM card on another phone, it worked just fine. I did not have any problems with signal reception. Sorry for the confusion.

did you buy the phone used, or off ebay(or similar)? maybe your phone is blacklisted..

I got the phone through a friend. Is there anyway to check if my phone is blacklisted?

Go to Settings and check your baseband. If it says not available or something like that then you'll need to flash a new radio
There is also software based bug for network mode. I have personally experienced this i.e. network mode doesn’t change in reality even if I select 3g mode. So, to force your particular sim card to switch to 3g only mode, first deactivate/disable other sim card on Yureka from setting> sim cards menu. Then dial *#*#4636#*#* > phone information. Tap on Turn off radio button and wait until the button reads turn on radio. Select WCDMA only from dropdown menu above the button. Wait a few seconds. Now tap on Turn on Radio button. Your desired sim card will successfully connect to 3G network. Now go to settings and sim card option and activate the disabled sim card as well. You may need to manually search for network signal if no network is shown. Also you may need to restart the device. If in 3g mode, your phone doesn’t connect to internet, Go to apn setting to ensure correct apn is selected. Sometimes APN menu might not show any installed network settings, in such case, just restart the handset. All these network related issues will be hopefully solved in the next Yureka ota software/firmware update.
after you did this you need to reboot your device......

Hi
In my yureka mobile, Sim 1 is suddenly getting disconnected and not detected. I tried to swap the sims then again the problem persist with same sim but not the sim1 slot. I am using the mobile with same sim cards from more than 20 months. But this peculiar issue started occurring from last week. Again the sim is getting detected only after restarting the mobile. I am facing this issue more than 10 times a day. Can you please provide me the resolution.

Same problem.. Have u got any solutiom
Have tried *#*#4636#*#* no use at all, Still no signal
after flashing cm12.1 my phone stopped getting network..... i have tried every possible way to fix it( APN, network selection, powering off, deactivating- activating, *#*#4636#*#*, etc....)
Please Help its urgent:crying::crying::crying::crying:
My Note 3 SM-N9005 is getting "Not registered on network - No service". When i put my sim card in, it asks for SIM PIN and I type it. Then I get "Emergency Calls Only" or "No service. It wont connect to my SIM CARD NETWORK. Whenever I change networkmode between "LTE/WCDMA/GSM" to ""WCDMA/GSM" my network operator come up in 5seconds and dissapear again back to "Emergency calls only - No service"
The strange thing is that my 3G works. Also my contacts on SIMCARD syncronize to my phone. That means that there is nothing wrong with the simcard/slot.
My IMEI is not blacklisted. I have checked.
I have factory resetted the phone and flashed tons of firmwares but no luck..
PLEASE HELP!
