They come in a 3-in-1 body and can be ordered as dual-module cards with two independent chips on one piece. The cards ship blank so you can write your own data later.
1. Card Type, Color, and Dual or Single Module
This is a programmable SIM card (USIM / ISIM). It arrives blank and is meant for later personalized writing.
