Since the UICC unlocking, my 306SH is showing this error every time the phone is restarted. Also, it keeps showing the initiating data and voice configuration. Although it is working my local CDMA SIM in India.
Same issues occurs to mobile also.

Hi there,
Just a few days ago i bought a LG Quantum, everything seem to be working fine until everyone told me why i didn't pickup their calls. I can make calls, the 3G it's working, I can receive sms, Wifi and BT working too.
It's SIM unlocked and working on Telcel Mexico (UMTS 850)
have you tried to turn of your mobile data connection?
for edge and gprs: they are only capable of one thing at a time data or calls.
3g already does both.
Yeah I tried that, I did downgrade to NoDo and now just shows "No Service", for a few seconds have service, I tried with another providers and shows the same behavior. Its not enough with the SIM unlocking? Maybe it doesnt have the XML of the provider or I must debrand? Anybody have an idea?
For the record, now im on movistar, with the sim working on a Samsung Focus shows "movistar", on the Quantum shows "movistar-movistar"
I just received my Google Edition of the S4. It works fine with most features but it does not allow any data connection via the mobile network (WiFi works fine). Voice calls also work fine.
I spent one hour at a local AT&T shop and also one hour in a phone call with the AT&T service hotline. In the shop, they replaced my SIM card and tried several tricks with the IMEI, but without success.
GoogleSupport suggested a factory reset - also no improvement.
Switching the phone to 2G mode in the mobile data settings also did not help. I also tried with a different APN (copied from my old phone), also no connection.
In my old 3G phone (quite old Samsung Captivate) everything works fine.
Could this be a hardware problem, a strange software issue, or in the end an issue with AT&T?
Send Phone back to google? Try with a similar phone a second time?
I read that there are sometimes issues with LTE but these guys seem to have data at least - just too slow. No Data seems to be a different thing --> new thread.
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

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 G900R6 that came from Cellcom. They claim their phones to not be locked at all. I finished the contract with them, paid it in full and installed the new Cricket SIM while at the Cellcom store. It connected to the mobile network, properly made a phone call, and received text messages from Cricket. Less than 5 minutes later the device received a system message from Cricket to install the APN data, text, and mms data. I installed all 3. It still shows connected to AT&T network and can receive texts from the cricket system. I does not connect to the mobile network, cannot send a text, and when trying to make a call it instantly says "No SIM or SIM error". It worked fine prior to receiving the APN information from Cricket. That may only be coincidence but I don't believe the data looked correct. There is however no area to change the APN data under mobile networks. The whole section is missing. Is there another way to view or edit this information to see what is currently stored? This must be saved in a file somewhere.
I own a SM-G935V that I'm using with Tracfone. It's running 7.0/Nougat, patch level 4/1/2017. On another forum, here's what I wrote:
I've run multiple tests on this and it turns out that if I reboot my phone, I do not get reconnected to cell service unless I make an outgoing telephone call.
The reason why I didn't notice this is because I use Google Voice for about 99% of my SMS communication. So here's the test I ran:
1. Reboot phone, wait until it comes back online and I have bars and 4G on my status bar
2. Call my phone from another phone -- goes straight to voicemail
3. Send SMS via phone's SMS -- goes to pending and is never sent
4. Make an outgoing phone call not using Google Voice but my cell network resolves the issue
I've changed the network from Global to LTE/CDMA, but it makes no difference. I've also turned off the wifi and tried to see if I would be denied for data access, but that is not so -- I can visit websites without any issue. But doing that DOES NOT reconnect me to my cell network. So it seems that since I'm using 4G/LTE for data, that authentication is separate from the cell authentication.
I got a response from another user that's experienced the same issue. He said he had no problems with Verizon prepaid SIM but the same exact thing with a Tracfone Verizon-piggybacked SIM. His solution was to push an unbranded firmware on it.
I'd rather not go this route if I can help it since the phone works well and this is the only issue I've encountered. Any suggestions?
