SIM was not working anymore "invalid network mode" - what happened there? - ONE Q&A, Help & Troubleshooting

Hello
A few weeks ago, I did something stupid.
I went into the *#*#4636#*#* app, phone info and pressed some of the buttons.
I think the button was "cellinfostrate <number>", altough I am not sure, but it was a button there.
After pressing it I lost the mobile connection. I couldnt get it up anymore, the SIM card was not working anymore even in another phone (LG G3). I think it was an IMEI problem, but not sure. I got errors like "invalid network mode -1" in the cell network settings.
I got an exchange for the SIM and it is working again.
But the question: What happened there? Why did the SIM was not working anymore?

SIM card error

HI All;
I am facing unique problem
Here is description-
I am from India and using 'Idea' as a network provider.
My cell phone is HTC touch.
Today for some time I switched off my cell phone for couple of hours , and switched it ON for a use. But since I switched it ON i am getting following Status on status bar
'phone off'
'Searching'
'Idea'
and then again
'phone off'
'Searching'
'Idea'
It keeps on happeneing
I did follwowing things
1) Soft Reset my device
2) Hard reset my device
but nothing seems to solve the problem.
Then I removed my SIM card and put it in Nokia device . While switching ON it dispalyed me a message 'SIM ERROR' . But I was able to make a call and receive messages.
Also I put another SIM card in HTC Touch and phone worked perfectly fine.(I was able to make a call and receive messages.)
But when I put my orginal SIM card in my HTC Touch again above mentioned problem start occuring.
Can any body guide me on this..
Thanks in advance
have u tried contacting ur service provider? they can tell u if theres any prob in area, refresh the network sim, check status of sim and poss replace sim.?
yip, im with Davey on that one, sounds like a faulty SIM card, happens rarely but does happen. Get a new one from your provider.

[Q] HELP, Phone stuck on Emergency Calls Only

Hi,
I am actually on holiday, and for the first few days my nexus s (running masters deodexed 2.3.3 with voodoo kernel) was working fine. However for the last day and half, it has been stuck on Emergency Calls only. I have tried everything to fix it, switching to airplane mode, full reboot, going into settings, wireless and networks and manually selecting a network but it still only remains in Emergency mode only.
I pressed *#*#4636#*#* and under phone information, GSM service says Emergency Calls Only
I have tried switching off and on the radio and fiddling with the preferred network type but nothing seems to work. I dont know if this is a roaming issue (i dont think it is because it was working fine initially abroad) but any help will be most appreciated.
Thanks,
Hi, I am having this same problem too. I have the Nexus S from Koodo and it seems like it doesn't "like" my simcard. I also have a fido simcard on me and the Nexus S works fine on my Fido simcard. Today i went to a Koodo store and tried another one of the simcards and it didn't work either. So far I think my Nexus S is defective. You can PM me your email if you like if you want to see if i fix it.

sim tray and network not working properly

a few days ago I switched from cm to AEX 7.1.2 on my moto g. Whether that has anything to do with it I don't know.
Anyway last night the phone was working fine then this morning I see that the cell network is disconnected and the phone doesn't see the simcard. However when I put in another simcard from a different network it works normally. I switch back to my sim and it works for about 20 seconds where I can make a call or text then it shuts down again and dowsn't recognize the sim then does again once I have switched the sims but only for 20 seconds. I don't understand what is happening to the phone and why it is doing this. I need help. I have tried picking different network modes from the list after inserting this code #*#*4636#*#* nothing has worked so far. I haven't systematically gone through each one at a time yet and the list is quite long. I haven't seen a list of modes that long before there are over 10 of them from auto prl to scdma etc... Some of them I have never heard of like the scdma one. wif and bluetooth are working ok if that means anything. Thanks for any help
Also when I go into settings the network section is greyed out and under prefered network type it says Invalid Network Mode (-1) Ignore. I only tried changing the modes when this problem arose my changing these modes was not the cause
i've had similar issues, when i skipped using mobile data for a long time, my non-data SIM would dropout intermittently. i changed SIM slots didn't solve it either. other SIM was fine in either slot. just before replacing what i thought was a faulty SIM, without turning mobile data on, i just set the problematic SIM for data. that solved mys issue. however, running mobile data on back on the original setting didnt cause any more issues either.

mobile network doesnt work

I have an interesting issue... I dropped my phone on floor today. When I take my phone to my hand, It was writing "Insert SIM CARD" on screen. I tried everything but mobile network isnt working...
I tried to clear sim socket, reset networks, turn off/on phone, another simcard (also not working)
Do you have any other suggestion?

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
@en11gma Are you on android 9 or 10,and what is your security patch level?
Thanks.
