There isn’t anything in the ICCID (SIM card #) that will indicate whether it is a 2G or 3G SIM card. However, if you’re looking at the SIM card itself you will see an orange 3G fireball on the front or a white 3G printed on the back. If there is no 3G text on the SIM card at all, it is a 2G SIM card.
