In connection with the increasing questions about the life of 2G (GSM) modules, we want to inform you that:
Any manufacturer of modules in the life of their products depends on only one factor - components for the modules. And if it is easy to change the supplier for resistors and other small components, that is, one part that cannot be changed is the chipset.
As more and more countries are turning off the operation of GSM networks and the profit from the production of these chipsets has fallen significantly, today almost all branded chip makers - Qualcomm, Intel, Samsung, have stopped producing "pure" 2G chipsets.
Based on practice, after the announcement of EOL 2G chipsets, another year or two manufacturers will be able to work on stocks purchased for customer programs.
After the stock ends no one will have "pure" 2G modules. Production areas are being freed up for new lines for chipsets for 4G and 5G devices. Based on the lifespan of the chipsets, which are precisely known to the manufacturers of the modules, the lifetimes of the modules are declared. You can read the SIMCOM
