Why won't SIM card work on the BLU Studio X8 HD?

I know where the sim card goes, but my micro sim card won't work, unless im putting it in wrong some how.


I have a similar problem. I tried my SIM card on a Samsung phone and it works fine. However, when I tried it on my brand new Blu 8x hd, I keep getting a message indicating that SIM card is missing

Hi Shelley. Which SIM card are you trying to use? Also, have you tried using the SIM with other phones?
