5G SIM Card by Watchdata is a Universal Integrated Circuit Card (UICC) designed to secure 5G network access. It aligns with the 3GPP R15 specification and employs 5G SUCI calculation to protect user IMSI from external attacks. The 5G SIM Card is characterized by low power consumption, which extends M2M terminal battery life up to 6 years for various M2M applications.
