My Qteks200 can't read any sim card. I tried to uncolck it with Lokiwiz03 & Lokiwiz03a but there was no change! when I insert any sim card it say: ' Invalid or Missing Sim card'. Please help me! What should I do?!
Normally QTEK's are NOT SIM Locked as they are not sold thru any Phone Provider.
Maybe your SIM is infact invalid? In other phones as well?
Or i have heard that like in Dubai, some phones are locked by the seller to be used only in their language/country's SIM.
Have you tried asking the place where you bought it from?
my qtek s200 don´t recognize others sim cards, only recognize mine.
Everytime i put a diferente sim card the phone ask for the pin, and after that it says please insert sim card...
i already chage the rom and the problem persists.
Anyone know why??
thanks in advance
Hi. One time ive damaged my sim card reader pins, :crying:
I'm living in poland so i had to order sim card reader from Italy, our service doesnt have any spare parts for this model
After i've changed simcard reader, my sim card is still "invalid or missing".
Dont know whats wrong. Can anyone help me ?
Reflash rom doesnt make any difference,
diagnosis all (network etc.) is disabled
SIM CARD READER has simlock ?
My friend have bought S3 Neo 3 days before - in which the second sim card slot is not working. The sim card status in sim card manager saying No Network Card
Refer the screenshot below.
If I switch between sim cards then sim 1 is working perfectly. What does no network card mean??
Please help ASAP.
My device is i9505 and it should be carrier unlocked, I bought it outside any carrier.
I have this device since mid 2013, with the same carrier and same SIM Card.
I only had 3G, and my SIM Card only supported 4G
Recently I noticed that they don't work anymore with just 3G, everyone with compatible device and SIM Card could use 4G
So I went to my carrier, and bought 4G SIM Card, it's from the same carrier I used for the last 3 years
But when I tried using it, my device said "Invalid SIM Card"...
I asked them to try the SIM Card on one of their devices, and the SIM Card worked, but on my i9505 it says "Invalid SIM Card"
I tested with my old SIM Card, and the device found no problem, but when you get a new SIM Card the old is blocked, the device recognized the old SIM Card but I can't make calls, receive calls, etc, etc...
As using my old SIM it still recognizes, I think it probably isn't a hardware problem...
Does anyone knows what could be causing this, and is it possible to fix?
I'm currently using Imperium LL v13 (Custom ROM)
I tried flashing a newer modem from my carrier based on this firmware:

I downloaded the modem from this post:
http://forum.xda-developers.com/showthread.php?p=61852508#post61852508
But it still says "Invalid SIM Card"
I also tested SIM Cards from some friends that use other carriers, these SIMs worked on my phone, and my SIM worked on all my friends phones, but when I try my SIM on my phone, it doesn't work...
On the screenshot below you can see my baseband version after flashing the newer modem:

I had the same exact problem with my I9505 with my operator digitel ( venezuela) , the only solution i had was to ask them for another type of sim card
So it turns out that Lossadax was probably right, the store that I went probably had a type of sim card that wasn't compatible or they had defective sim cards there
I had to buy another sim card from another store, the connector had different size and layout, and now it's working!
