Hi Guys,
I have pbm with my S4, Rooted, locked Rogers, android 4.2.2, MG1.
can't access to the mobile network, the SIM card works well with other phone but when i plug it to my phone it detects the network and it display "Rogers" then it turns into No service, then it comes back to rogers and so on and i can't connect to 4G network. Even if i take the SIM out of the phone and i turn it on, it display No SIM card for 3 ou 4 seconds the it turns into No Service and so on.
I tried to reset to factory settings, turn filght mode on-off, but it still the same pbm.
Do u think it is software pbm? can suggestion any solution,
Does flashing the Baseband would help?
Thamks for ur help
Have you checked if your apn is set up correctly? Settings, more, Mobil networks, access point names.
What is you baseband or radio? Maybe you have lost it.

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.
Hi All,
I have a Sprint S4 (SPH-L720) which i got from the states. I plan to use this in Canada...was able to root/unlock the phone via SIM Unlock Method posted (http://forum.xda-developers.com/showthread.php?t=2415587&highlight=sph-l720).
My issue is that i am unable to browse internet or use any apps needing internet on the GSM/UTMS network mode. I have a Rogers LTE chip that i am using and am able to use the phone (voice calling) with no issues. I can use internet on wifi but am unable to when trying internet via the phone chip...i do have a 6GB plan with Rogers and can browse internet when used on another phone.
I had to downgrade the Baseband to MDL/MDC to sim unlock the phone and have later installed MF9.
The software version and baseband now on the phone is: L720VPUAMF9. Earlier had an issue that the wifi was not working, option was disabled...(was getting a message - that an app is trying to connect...) this got fixed after i flashed the kernel version.
Can anyone advice how i can use data from the GSM network and not wifi.. has anyone faced the same issue.
Add your APN for your gsm sim under APN settings.

Thanks guys...i was able to get the APN settings and now my phone works on data from the lte chip inserted.
Now my issue is that my phone does not show LTE....i have another S4 with Rogers and i verified running speed test on a friend's phone to compare...my specs on the sprint phone are almost 40% lower than his phone on the same network..ran from the same location (apt). I tried various combinations i.e. (LTE, LTE/CDMA, GSM) but i can only get 3g or H+.
Any suggestions that i can try...Thanks!
This phone doesn't have the proper bands to work on Rogers LTE.

Hi all, recently bought a fake s4 in Thailand which I've figured out is an Alps branded phone?
My problem is that my Three UK sim card won't appear to work in it, I'm not sure if it's the frequency of the cellphone network that won't allow it, or if there is something that I need to unlock in the phone. I've tried some of the unlocking codes from online etc but being that it's fake none of them seem to want to work. Not even sure how to access any of the service menus on it.
From what I can tell three network operates only on 2100mhz. My guess is that this phone does not support this frequency. How can I find out what frequencys the phone supports?
Thanks
Also, just to let you know, when I go to mobile network settings, under data connection it says "3 UK". So it seems the phone is recognising the sim? But still unable to get any signal etc.
Also have tried using Network app from Play store and forcing phone into WCMDA mode which is what Three uses, but won't even allow me in the app, or normal settings. Just keeps switching back to GSM straight away.
Following an Odin upgrade on my i9505 to the official 4.4.2 release my S4 was working fine but, when I rebooted later, mobile data was disabled and when I tried to enable it a message appeared saying “Insert SIM card to access network services”. I rebooted several times and finally I was able to access mobile data without the message appearing.
My SIM card is locked with a PIN and I noticed during the multiple reboots that when the phone first boots up to the SIM unlock screen up it was showing a phone signal, and when I entered the PIN the phone signal disappeared briefly and then came back. I figured this might be the point that 4G is lost, so after I managed to get mobile data working again after a reboot I was able to disable the SIM lock (when I lost mobile data the SIM lock option in security settings was greyed out). Since I've disabled the SIM lock I've booted multiple times without issue. When I re-enabled the SIM lock the problem came back straight away.
Can anyone suggest what the problem might be, and how I can re-enable my SIM lock without losing 3/4G connectivity after most boots.
TIA

my 3g is not working
no issues with wifi
what could be the problem
2g is working fine(GSM Only)
i am on kot49h rom
I'm having the same problem! I've disabled SIM Card Lock, will let you know how I get on.
Same here
unbranded i9505 using on EE 4GEE
updated and soon after lost mobile data - tried reset & new sim card - nothing. EE are now fully blaming the update and pointing Samsung and HTC customer to manufacturers.
After changing sim it seemed to be ok for a while but now comes and goes. What i have noticed is that my phone will be fine until a restart/power down and sometimes flight mode will fix. Original sim was normal micro sim new is NFC micro sim just for info
this is such BS and samsung are dragging the heels with a fix.
Hmm. I'm with EE 4G as well. I have found that with the SIM security PIN disabled it's more or less OK the majority of the time.
Sorry forgot to mention this was a OTA update
Also noticed that phone will not connect to kies correctly and show phone number as all zero when is connected
can anyone else confirm that?
I have a Galaxy Note 3 with a problem. 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.*
I have tried/Things I know
-Checking Network Operator and select network from there. Tried also "Select Automatically" still nothing happend. It pops out " Registred on network" but it is not.
- I have changed Network Mode from "LTE/WCDMA/GSM" to "WCDMA/GSM", then!! My network comes up in 5 seconds and go to normal again "Emergency Calls only"*
- My IMEI is not blacklisted! It comes up on screen when typing *#06#.
- MY PHONE connects to the 4G perfectly! I get internet to surf from my SIM CARD! It means the phone is actually connected to the phone. BUT why dont it connect to the operator so I can call?
- Also I have saved contacts on my sim card and then sync to the phone, that means that the SIM is connected to the phone.
This is not a hardware problem, I changed the antenna, but still the same problem happend. I believe this is a software problem.
Everything I change between Network Modes, my NetworkOperator came up in the top corner left in 5 seconds and then went to "No service/Emergency calls only"
I have also factory reseted and installed stock firmware from my country.

Is it possible that mobile network signal happen to be poor at the spot where you are?
Hope anyone others below will help you. Anyway, good luck to you.
The signal is full.
