Dear members,

Can someone explain what is the technical process to convert a SIM into Data based SIM. What protocols and parameters will be retuned to do this.
Once, a SIM is converted to DATA only, will inserting it into a phone to make a voice call, will it do it.

Asking in regards to 3G/4G technology
