🔹 What is a USIM Combo Card (2FF + 3FF + 4FF) – Half Card?
A USIM Combo Card integrates three different SIM sizes — 2FF (Standard/Mini SIM, 25mm x 15mm), 3FF (Micro SIM, 15mm x 12mm), and 4FF (Nano SIM, 12.3mm x 8.8mm) — all embedded within a single half-size card body (2FF-sized card with cutouts or removable layers exposing the desired size).
- Memory Capacity: 128K (standard for USIM applications)
- Form Factor Covered: 2FF + 3FF + 4FF in one smart card
- Card Type: Half Card (also called Plug-in SIM or Standard SIM with multi-size capability)
