MC7455 - unable to clean status reports at "SR"

of course i am not using 1234567 during my test!

Here I have performed your commands one by one. Please note that this is after modem reset with “at+cfun=1,1”. The only difference I can see that “at+csmp=49,0,0” returns an error, despite that it still seems having the effect

then probably this is network dependent

How can we possible resolve the original problem? Can it be relayed to the developers?

this module has been end of life

You need to get some workaround, for example, do a reset if the storage is full

Ok. Thank you very much for your help.
