tab s T705 LTE micro sim card problem

Has anyone had problems with LTE tab s 8.4" sim card ?
the signal bars all the time are full as if there is sim card in the device. i tried inserting two nano sim cards with micro adapter it immediately asks to restart as Sim card detected..
I place sim card, restart and NOTHING !
same full bar signal all the time with/without sim. Still says no sim card inserted.
Device from singapore.
Now i know 8.4 LTE tab S is 3g/4g sim card compatible and sim cards work perfectly otherwise. i reset factory settings with no results !
going to mobile networks trying to chose networks also gives error of no network available.
ANy ideas/ Help !

Check your imei number. If imei starts 00..... you have problem with logining to network.

I have the same thing as well when no simcard is inserted. Per understanding, the phone automatically logs on to any network so you could dial the emergency number (in your country)

[Q]Network drop on non data enabled sim.

I am using XT1068, Updated to latest 4.4.4. I use 3g in the first sim and I noticed that the signal drops to zero in the second sim & some times I get 'Emergency Calls Only' in the second sim. I don't know If the problem is with my network provider or my phone. Pls check and help.

did you try swapping cards ?
are you using micro sim card or cut micro sim card from normal sim card?
Swapping cards didn't help. I tried that before. I use micro sim cut from normal sim.

T-Mobile sim card in Verizon phone?

I just tried fixing a broken Verizon HTC One M7. I only have a T-Mobile sim card to test it out. I just wanted to see if the sim card reader is working but it says No Sim Card with the tmobile sim card in. Is this normal or is this indicating that the sim card reader is not working?
Thanks

WInd Mobile Canada No connection?!?!?!?!

Hey I for some unknown reason cant connect to my network whatsoever. No 3rd party roms nothing just the most recent Lolipop update. Sim card is in lock screen says emergency calls only. Network operators all options are greyed out. Here is the weird part. Under APN's it tells me there is no sim card when the screen loads, however when i eject the sim card and put it back in its not until i eject it that the rest of the phone recognizes there is no sim card. Did my sim card fry or what do you think?
Some answers found solo
so i pulled an app off play to check the info of my sim card and lo and behold there appears to be nothing on the card whatsoever. anyone have a suggestion for an app that is known to be current and working for this just in case its the app?

Simplest would be to go in store and ask another sim card just to test it. Looks like a bad sim card or maybe an hardware problem with the sim contacts

Dual SIM Note 8 Poor Network connection

I've got my phone setup with a Fido (Canada) data SIM and MTN (Nigeria) SIM for roaming in the second slot. I am using a sim adapter so a 128gb Samsung memory card is also hooked in. For some reason the MTN roaming SIM will not receive calls, most callers to that SIM card are told the number isn't available. However, if I switch off the second data SIM, the First SIM will then be able to receive calls without any problems. I've taken out the sim adapter and memory card, but this still persists.
Has anyone experienced this before or know a way to fix this?

So the phone is not a dual-SIM phone, it is only with the "adapter"?
It is a dual SIM phone alright. These hybrid dual SIM can either take two SIM cards or one SIM card and a memory card. If you want all 3, then you need to use an adapter to achieve that.
