EG25-G SMS message storage size

Please tell me about the EG25-G module.
I am using two different lots of modules and the size of the SMS message storage for each ME is different.
One has 255 storages and the other has 23.
The size of the storage was confirmed by “AT+CPMS?”.
Is it possible to change this storage size?
If so, how?
If not, how can I distinguish the difference between the two modules? For example, the type name…
