My network service provider gave me a second data only sim card for my nexus 7 3g tablet. So I have 2 simcards but only one number...
Before I got the 2. data only sim everything was OK with the voice+data sim in my SGS3 Mini, but after I installed the 2. data only card in my tablet sms and video calls are "routed" to my tablet. I want to permanently install the tablet in my car so I need sms, video calls and notifications on my phone. I tried to google and read somewhere that the network would use the sim registered last or most recently as primary simcard, so I tried to turn off my phone for a few minutes, but this doesn't seem to solve my issue. I use cyanogenmod11 on both my tablet and phone, so is there anyway to configure calls, sms and video to my phone instead of the tablet?
I tried to search my service providers knowledge base but didn't find any info regarding my extra data only simcard so I guess this is a new option.
as the title says , am getting a network signal in the status bar with no sim card installed in the device , where it used to show a stop or block sign before when there is no sim installed , don't know when it started but i have noticed it a week ago , and am on the 5.1.1 update ,
what i have tried so far :
1 - reset the device from the setting .
2 - reset the device with samsung smart switch for windows ( which download the latest firmware for the device & install it ) .
3 - installed the factory firmware with odin , and got the device to axiom telecom which is my warranty service provider , and the told me the have changed the whole motherboard , & after telling them the issue is still there , they showed me another s6 with no sim and there is signal and told me that this behavior is normal ( which i don't think so ) .
4 - contacted samsung directly by phone & email , and they told me to reset the device or send it to service ( which i already did ) .
so , is this behavior really normal ? are any of you guys getting this ?
my device : SM-G920F
country : Saudi Arabia
no its not normal
if you type *#06# you gonna find IMEI become 3500000000006/01
if it is then you cant make calls or send sms ( not registered on network )
its the same problem like me i don't know where this come from but we need some one to give us backup the EFS folder. to restore it back to the phone SM-G920F
please if some one can help us thank you

no , it seem we are having different problems ,
*#06# reveals normal IMEI ,
and i can make & receive phone calls & sms if i install a sim card ,
try resetting yours to stock ,
other than showing a signal with no sim card installed the phone is fine & doesn't have any problems .
Speculation- you'd need emergency service call? I would assume that it's allowed to connect to network for that and not have phone disabled?
More speculation- your being spied on...
-Spy
It's only a display icon. You aren't able to still make a regular call without the sim? If it ain't broke don't fix it.
But to ease your mind just check the network status in your settings. Should say what connected to.
Surely it does have to do with the update itself if your phone still functions as normal.
I'm sure there is a network status with the super secret spy codes that you enter on your dial pad. You know the #secretrandomnumber#* codes...

it could be there for emergency calls ,
in terms of being spied on , ha ha ,i don't think so , the service center changed the entire motherboard which include the eMMC with it's whole partitions .
the sim card status in the settings says Not Available for everything , and yes i can't make calls nor sms without the sim ,
but you still didn't answer my question : do you get this when you remove your sim ?
no one with a similar problem ??
I've seen it on lots of Samsung phones. It's simply a signal for emergency calls. You have to be able to make emergency calls with or without a Sim and that's telling you how much signal you have.
Seriously people this is pretty simple and no conspiracy.
You only get a circle with a line through if you have a sim card installed that is blocked from the network or the phone is stolen / blocked etc.

good to hear ,
what made me think it isn't ordinary thing is that the service center didn't know about it & thought it was a problem ,
thanks a lot .
This was done on last update Samsung gods thought we needed to know how much of a signal we had for emergency calls
Having the same problem with my samsung galaxy s6 SM-920F. showing bars on the signals even without sim. not connecting to network operator as well. showing Disconnected status in SIM status from About.
Tried updating the software even downgrading, factory reset and wiping cache but nothing worked.
Found this thread when looking for an answer to this question. In my case, it is a tablet that hasn't even got a sim option but still has the mobile network signal showing, even when airplane mode is switched on. Just worry it is eating some of my battery life. Any ideas?
I am also getting same problem.
There is no sim card inserted in my phone but still it shows the network bars.. Your And my problem is same.
There, an actual answer. Guess I should add it here since I wondered the same thing
a sim card has nothing to do with the transceiver system of the phone. its literally a "passkey" it is your authentication to USE that network. ie you can always SEE the network you just not allowed to "use it" without permission hence the simcard.

Hi. I`ve got an MHA-L29 and I`ve got a problem with dual sim settings. In dual sim setting menu if I select default mobile data (4G services associated with default SIM) on SIM 1 then I lose the signal from that sim (Emergency calls only) and I`ve got SIM 2 signal. If I select default mobile data on SIM 2 I lose signal from that sim and I receive signal on SIM1. Basically, I can`t have both sim working (network signal) because I need to set 1 SIM on default mobile data and the one that I set it`s losing signal.
Maybe someone can help me. Thanks

This is strange behavior.
By default there is no problem. See my screenshot.
I suppose it is mobile operator's problem.
What is your full version (settings / about phone / build version) ?
What is your country and mobile carriers?
It`s not a mobile operator problem. I use the same sims on mate 8 and it`s fine. It`s exactly like in your screenshot, sim 1 default mobile data and I lose signal, and I have signal on sim 2. If I select sim 2 default mobile data I lose signal on sim 2 and receive signal on sim 1. So basically I can`t use dual sim and mobile data.
I`m in UK with BT and Lycamobile.
Build version was MHA-L29C432B198 but I`ve tried different things and now I`ve got nrd90m test-keys.

Agree, C432 region is for UK too. So your bug must not exist, but it is here.
Nrd90m test-keys means that metadata from oeminfo does not match with current ROM.
Did you try to rebrand? If yes, just flash ROM again what you flashed last time.
I`m trying now to rebrand, watching tutorial but I`m stuck at
After device enter TWRP, connect to USB cable.

Something blocked adb. Maybe HiSuite. Turn it off, then check that pc recognises device.
adb devices
You can issue to refresh adb
adb kill-server
Phone must be in twrp.
I`ve managed to do all the steps, but after restart I can`t get past the Huawei logo, phone enters in Huawei eRecovery where I have Download latest version and recovery (restore your system with wifi) reboot or shutdown. I`ve tried to restore the system with wifi but I can`t (getting package info failed). I don`t know what went wrong during the process but the phone it`s stuck at huawei erecovery.
So now I`ve managed somehow to update emui to 8.0 and android 8.0 and I have build number MHA-L29 8.0.0.321 (C432log), but the initial problem it`s still there.
I still can`t use mobile data or both sims in the same time. The sim selected to be default mobile data lose signal.
I`ve tried to use 1 sim and sdcard but I don`t have signal because the sim it`s set by default to be mobile data.
Anyone?

Seems to be hardware issue. Do you have warranty?
I don`t have warranty. Both sims slots work fine one at the time, not together.
I need 10 posts on the forum so I can upload a screenshot.

OK. Last thing - try to delete and recreate apn settings.
Don't think that they all incorrect, but maybe one of them...
The Mate9 is active/passive: it's impossible to make a call using sim 1 and using mobile data with sim2 but in stand by you can receive calls on both sim. This limitation is not present on mate8 and mate10.
Piergiorgio
I`ve tried other sims, put new apn and it`s the same.
pgmunzi I can`t because I don`t have signal on one of the sims. In dual sim settings, I need to set sim1 or sim2 to be default mobile data. With sim1 set on default mobile data, I`ve got signal on sim2 and no signal o sim1 (emergency call only), not even to receive. With sim2 set on default mobile data, I`ve got signal on sim1 and no signal on sim 2.

You can only have data on SIM1. Both sims can be used for calls and SMS (to my understanding). If you have two SIM cards from the same network it should not be a problem, overall. If you have two different networks (one on each SIM) then you might have some issues.
If you have the SIMS on the same network, and they use the same APN, you might want to copy the settings to two different APN's a label them for SIM1 and SIM2.
Also be careful of what version of OS you use. If you download a version that is originally branded for something else, then expect problems. There are also "Gotcha's" with firmware that is taken from one device and reconfigured to work on your device. Usually this is a matter of rebranding and copying underlying code over. This too causes issues with dual SIM phones. I have found this to be true with my MHA-L29C567. Sadly, I would love to have a memory card under the second sim slot along with a second SIM, but I have yet to figure that one out...

Just got the same problem (2 sim cards from same network, only obe working at a time) and thanks to you it's solved. I just had to rename the second APN differently.
I have the same problem. Is it solve? Hv been searching for solution.
Hello guys.. I have the same problem in my mha-l29. Did you solve it?

hi i just wanna ask if uve solved this, Im currently facing the same problem
my both sim are working fine but some time one sim card not work when i reinsert sim. it does work. so what is the issue?
Hi all,
Here is my situation and problem. I have 2 Sims:
SIM 1: Google Fi - my personal number, I want to use it for phone calls only even though it has a small data lan
SIM 2: Verizon - work sim, I want all the data to go through here.
My setting is phone call sim 1 and data Sim 2.
When I make a phone call via SIM1, I lost LTE on my SIM2.
I did call Verizon to get the CDMA LESS feature turned on.
If I were to change the setting to phone call and data through the same sim, then VoLTE works just fine. So I think this is an issue with the phone itself/settings.
Thoughts?

You need to go into settings "SIM & network settings".
Select "Dual 4G networks".
I don't have your issue.

Can't believe there are so few of us having this issue. Why would the LTE turn off when I'm not even using that sim?
Probably many are using just a single SIM.
Have you tried switching the sims in the slots?

I have no help. In January Mint had an issue where their SIM had to be in slot 1. So I flipped SIMs. Truphone won't work either.
LG V50 Sprint no calls and sms?
I got this phone unlocked and updated working fine with LTE data connection with my provider here ooredoo Algeria fast and stable.
The problem itt showes phone signal is full but when I dial a number it says "no sim card"
+ sms is not working altogether as well.
Any help fix / pointers would be greatly appreciated
Hi!
The same thing happened to me, I couldn't send messages or call until I activated the automatic network mode, otherwise it wouldn't let me call.
I hope I have been helpful with this.

The same problem happened to me, i tried everything..
The only thing that fixed it is:
1. Insert a Sprint SIM card (in my case it came with the device when I baught it. I never had service from sprint and I lived overseas)
2. Select settings >> Network and Internet >> Network settings reset.
3. That is it!
Please note that this method only worked when I inserted Sprint Sim card, it did not work with my actual sim card..
After the settings were reset, I removed Sprint SIM, and inserted the other SIM, and it worked perfectly!

This worked once for me, then I had to remove my tray to insert an sd-card and didn't work anymore... network settings struggle to reset (will take 10-20s and then crash out) what could it be? I'm using a heicard and discussing the procedure in this thread: https://forum.xda-developers.com/t/unlocking-lg-g8-sprint-bad-esn.4092771/page-2
UPDATE: if you still get the "SIM not provisioned for voice" message, do a backup, then full restore of the phone, then repeat the above steps. You should now be able to make phone calls, but not connect to LTE. Download an app called "AddAPN" from the play store and manually save the Access Point Name for your carrier (yours will be different from mine, but I'll add it as reference, it's in italian, but you should get the gist, relevant steps are 10 through 14: https://www.helpforsmartphone.com/coopvoce/it/lg/g6/android-8-0/guides/22/Configurare-Internet-LG-G6)
with my sprint lg v50 and i can "Add APN" already.
i dont need an app
