Hi there, I have purchased my tab last friday, played around with it during the weekend (root, overclock, etc.) Everything was fine - internet connection via 3G and WiFi, battery life and so on. However after I swithed off my tab on sunday evening and left it on charger, monday morning I realised that galaxy tab 10.1 does not recognise any SIM cards. The device itself is unlocked here, in Lithuania.
Any ideas what might have caused this strange behaviour? Everything else is working fine.
Hi!
I have the same problem, started about a week ago. SIM-card just looses connection at random times. Mostly when i've just left it in the charger for an hour or two.
A reboot is needed then it's working as normal.
What do you think? Should i return it?
Did you try and setup the APN manually?

Obviously...
The thing is that device itself does not recognise SIM card. Once You try to configure APN manually, it sais "please insert SIM card" :-(
and reboot doesnot help...
I have this issue too! I thought i was the only one experiencing this.
I have this problem 1 time, but i tried to switch sim with the one in my phone and it worked. Afther i switched back again and still working.
I got the problem afther my tab have been switch off for 5 days.

Well, after I left device in one of authorised dealers, they acknowledged the problem and offered to replace this Tab. So it turns out, one can only hope, that it does not happen to him...
Hi guys
Turns out all my problems were caused by overclock kernel. Today my tab was replaced so first thing I did was root it again and make a back up. Then I installed OC zip file from SD card via CWM recovery. Guess what? Device did not recognise SIM card again... luckily I had a back up ROM. After I went back to the original ROM everything was OK.
So be careful before over locking your tabs.

my 10.1 tablet says please insert sim card after i have inserted the sim card is it possible..i bought it in hong kong and now am in africa...its kh5
my friends is kg7 and it works fine cud it b a software issue or hardware
same problem just happened to me.
is there any solution found?
sim is ok on my htc desire but tab 10.1 cant detect it.
it has stop suddenly while browsing some news sites.
reboot does not help
i tried with another SIM also, same problem - cant detect SIM card at all,
when trying to open Mobile Network it says - Please insert SIM Card or something simllar.
Also i found that in About Phone - Status, IMEI and IMEI SV are Unknown, Serial is OK, is this normal?
Look I know this is a dumb question, but have you rebooting the tab after inserting the Sim? A client of mine had the same issue and we struggled for days until we realized we hasn't tried that. Sure enough that was the issue.
I think the tab only tries to access the Sim card on bootup.
Sorry if you have already tried this.

sin not recognized on galaxy tab 10.1
I have the same problem. Tab says "plz insert sim card. I have already inserted sim card
Same issue here .. I picked up the tab on a business trip in India and it worked fine while I was in India . I came back to UK and tried a UK SIM and it does not recognize a Vodafone Sim , Giff Gaff but recognizes 3 . Even though it recognizes 3 it does not let it register on network.
Not really sure what the issue is .. Is it restricted in some way .. ?
The "Cant connect to Network" problem has come up again...........on the new phone
Dunno if its just my bad luck or what exactly is going on
Anyone else have this happen to them??
Alls been well since i got the replacement 3 weeks ago and then today it happens again
I get this problem at work but not at home. What's your connection like? Many APNs connected to it? That's what seems to be my problem at work

Everything is fine no matter where i am, just this morning it reverted back to the "emergency calls only", same as what my 1st Galaxy S3 did and when i go to select network it just says cant connect to network!
Sim card works in other phones no problem
Is your SIM card recognized by the phone?
Does it have a SIM Serial Number? (Afaik you can e.g. use Z Device Test to see the SIM S/N)
Sorry are you talking about cellular network or WiFi?
Sent from my GT-I9300 using xda premium
Cellular network, wifi is working fine, even my internet data works when wifi is off!! Its making calls and sending texts
So annoying
Phone is packed up and being sent to Samsung Service Centre 2moro anyway
Maybe it's your sim card, could it be damaged in any way? (cutting it down etc...)
Clean the contacts on the sim
Sent from my GT-I9300 using xda premium
Sim card is the original out of my iphone 4S and iv cleaned it with a micro fibre cloth!!
As i said the sim works fine in other phones
im having real problems with my honor 7, i cant seem to be able to use my 4g/3g slot ? the sim card only works in the 2g slot, this isn't really an issue for calls and texts but its a major issue for using my mobile data, like i say when i use the 4g slot all i get is emergency calls ? as soon as i switch it to 2g slot it works fine, its driving me absolutely insane, someone please help lol
did this happens with all sims ?

Yes with all Sims, it's almost like the phone will not receive a 4g signal ? But the 2g slot works perfectly
Installed custom rom?

i think you have a problem with slot or just dload the offical rom once and reset again
I've installed the stock rom a few times now and it makes no difference, it's weird because neither slot ( 1 or 2 ) will function as the 4g slot but both slot 1 and 2 will function fine as 2g, makes me wanna bounce the phone lol grrrrr
Can anyone link me to an official rom ? Just to make sure I am downloading an official one ? I'm sure I already am but just to make sure
Also everytime the phone dies, restarts or is turned off I lose signal and have to swap slots again
HELP!!! I have the same problem! Have you solved it??

No... If i choose to apply 4g in the same slot in which i put the sim, it loses the connection (for calls and mobile data). If i select the other slot, the connection comes back but only in 2G...

Hello,
I have the Note 3 Pro. Since I got it about a year back it's always had this problem: the sim just randomly disconnects and I have to insert the pin again. Most of the time this happens when i come back home and, presumably, it connects to wifi, but sometimes just driving and i find it's been disconnected for god knows how long.
Anybody else had this issue? Thanks!

Hi man!!
I often had this issue. I sent my phone to the service center and they told me everything looked OK, btw, they re-screwed all screws and now it seems to be better.
By the way, the best way for me to avoid that has been to use a tiny (which is really against the phone) and hard case, in my case iPaky gives no problem with PIN, without it, sometimes it fails.
Regards!
Don't use radon kernel.
i had the same problem on radon
I'm not sure it's anything to do with Radon, as I dirty-flashed RR back to the standard kernel and continue to get disconnected SIM 2. It would be nice if there was a way of getting the system to reprovision the SIMs via Tasker or eRobot when this happens, as I have to reboot the phone for the SIM to be recognised again.
Redmi note 4 sd
I just keep the SIM pin with my keys and just push the tray out and in again, whenever this happens (a lot). I know you're not supposed to do this with the phone on but restarting takes more of time. By the way my wife has a redmi 5 plus and the same problem.
Tbh I also sometimes face this issue with AGNi kernel, whenever that happens I restart my phone and the sim start working.
Has same problem from more than year and tried both nougat and oreo rom's and same problem but i am using hybrid sim adapter for using 2 sim+ 1 sd card , it's not a hybrid sim adapter problem cause it works fine on other devices.
What's the solution ? i am tired of this sh*t.

If u use sim2 data then it will disconnect. Sim2 only for calls.

Hi,
Just picked up a Wileyfox swift 2x and am having an issue using it in dual sim mode.
When a single sim is enabled it works just fine but when the second sim is enabled that sim does not connect to the network, if I disable the original sim the second sim then receives reception as normal.
Have looked on the forums but cannot see any other users having the same issue so don't know how to progress this.
Have used these sims in a dual sim phone previously without any issue so its clearly a handset rather than an operator issue.
Any help appreciated!

Ended up returning the phone and replacement handset worked fine so issue was phone specific.
