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

• 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, MC55 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
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.
• When is switched over from ''MT'' to ''SM'' all free ''ME'' locations will be filled with dummy short mes-

sages. This procedure can take up to 35 seconds, until all the 25 records are written.
If switching from ''MT'' to ''SM'' was not finished due to error or user break, the value of
but some of the dummy records remain in the ''ME'' storage. These records have to be deleted manually.
When equals ''SM'', do not delete the dummy messages in the ''ME''. storage. They will be automat-

ically deleted when you switch back from ''SM'' to ''MT''. Again, this may take up to 35 seconds.
If switching from ''SM'' to ''MT'' was not finished due to an error or user break, the value of
''SM'', but the ''ME'' storage will no longer be filled with dummy records. New incoming short messages may
now be written to the ''ME'' storage, if ''SM'' is already full. To avoid this, repeat the
soon as possible to switch

''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
