Why my Qteks200 can't read any SIM card?

[qteks200]

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?
