[ask] ZTE C335

I have ZTE C335. When  I buy the phone, It is including CDMA Card from Flexi (one Indonesia biggest Operator).

I want to change the RUIM Card and when I insert the different card from different operator, the phone said "Insert UIM Card".

What happend to my phone? Is It locked?  But If I insert the card from Flexi, it is work. What Should I do?

Please anyone help me.
Thanks.
