Q1: What are the fundamental structural and electrical differences between Nano SIM and Micro SIM connectors?

Nano SIM and Micro SIM connectors share identical electrical definitions and both comply with the ISO/IEC 7816 standard. However, they differ significantly in physical dimensions and contact layout.

Nano SIM connectors require much higher contact positioning accuracy and offer far less tolerance margin due to their reduced size. Test data shows that if the contact misalignment in a Nano SIM connector exceeds ±0.05 mm, card detection failures may occur.

To address this, MOARCONN ensures stable electrical contact in its Nano SIM connector series through high-precision mold control and dedicated contact positioning structures, even within compact form factors.
