OPPO NEO 3. No sim card detected topic

My phone is rooted

Before this problem :

I flash my own port Rom using cwm.

And no problem on my ported Rom.

After I decided to flash another Rom it's ok nothing changed but when I flash ported Xperia Rom from the owner (not me) ,and I get the problem. No sim card detected.

I don't know why, but maybe because the Xperia Rom is cdma gsm, so my phone can't detect that because my phone is gsm gsm.

After that, I flash stock Rom and the problem still there.

Please help. Thanks
