Mc39i Gsm Modem
Overview
Product sourcing insights & recommendations
The MC39i GSM modem is a legacy industrial 2G module originally developed by Siemens/Cinterion. While it remains available as "New Old Stock" for maintaining existing systems, it has reached its End-of-Life (EOL) status and is incompatible with regions that have decommissioned 2G networks.
Market trends show a decisive shift toward LTE-M and NB-IoT technologies, which are projected to drive the cellular modem market to over $9 billion by 2034. For new deployments, it is strongly recommended to migrate to modern successors like the Cinterion ELS series or compatible "drop-in" replacements. Detailed specifications, market trends, and a comprehensive sourcing guide are provided in the report below.
The MC39i is a legacy product facing global 2G sunsets. You can continue with:
