Description
These 4G SIM cards, intended for CPE, are standards-compliant GSM SIM + UMTS USIM + IMS/VoLTE ISIM cards. Each card has a triple-cut form factor, fitting 2FF (classic SIM), 3FF (micro SIM) and 4FF (nano SIM).
The SIM cards can be used with any core network, from GSM (2G) through UMTS (3G) and LTE (4G) as well as 5G. The fully re-programmable nature of each card allows users to create/edit any files and directories (EF or DF) in the card filesystem.
