How to change SIM Card in My Mobile with anti theft Security

Dear all,

How can i change sim please suggest me.

My cell is HTC explorer.

Hi,

if you know the password, you can just insert the new SIM into your device. Anti-Theft will ask for the password and once entered, the new SIM will be added to the list of trusted ones.
