Hi All,
i am using a EC21-E modem in the same hardware environment with the same simchip. On both systems i run the same commands as seen below. Also the revision (EC21EFAR02A09M4G) of the modem ist the same. The only difference is the response of the URC: +CPMS:. It says that the usable storage size for messages in e.g. “SM” or "ME is 23 instead fo 255. Can sombody tell me why this can differ at that point?
