• The Mobile Equipment storage ''ME'' offers space for 25 short messages, see 

• ''MT'' is the sum of ''ME'' (= 25 locations) and ''SM'' (capacity varies with SIM card). The indices 

 of

the ''MT'' storage are dependent on the order selected with 

 

• The 

 and 

 parameter will be stored in non-volatile memory. 

• The user should be aware that the setting ''MT'' involves ''ME'' and ''SM'', with ''ME'' being filled up first. If the

''ME'' storage is full, AC75 will proceed with the ''SM'' storage. 

Incoming Class 1 short messages (ME specific) will be preferably stored to ''ME'' and may be transferred to

the ''SM'' storage if ''ME'' is used up. 

Incoming Class 2 messages (SIM specific) will be stored to the SIM card only, no matter whether or not there

is free ''ME'' space. As a result, the ^SMGO: 2 indication (see 

) may be presented without prior indi-

cation of ^SMGO: 1. For more information regarding SIM and ME specific message classes refer to 

and the following specifications: GSM 03.38 and 3GPP TS23038. 

• Multiplexer: In Multiplex mode or when the two physical serial interfaces are connected, the parameter

 will be the same on all instances, but the settings of 

 and 

 may vary on each channel

/ interface. As a result, changes on parameter 

 and/or 

 befor activating the multiplexer or dif-

ferences values for other instanes can result in not desired behaviours like different outputs for 

 and

so on. 

• While 

 equals ''SM'' and 

 equals ''ME'' it is possible that, after deleting short messages from

''ME'', the freed space on ''ME'' is reclaimed for new incoming short messages, when there is no space left on

the ''SM'' storage. As it is often the clients concern to have received short messages stored only to the SIM

card, inconsistent settings should be generally avoided. This can be achieved simply by using the same

parameter for all memory indices. 

• Users should be aware that when using this AT command quickly after SIM PIN authentication the SIM data

may not yet be accessible, resulting in a short delay before the requested AT command response is returned.
