5.1 SIM-card
UNICOM 300 can be pre-equipped with a SIM-card.
Suitable GSM-subscriptions are for example M2M subscriptions for GSM CSD and/or
GPRS / LTE cat. 1 data.
When using GPRS / LTE Cat. 1, UNICOM 300 requires several settings with which UNICOM 300 can
log on to an APN; such as APN name with the corresponding username and password.
5.2 SIM-card placement
Open UNICOM 300 (see figure 3, note 2). The mini-SIM holder is located in the lid of the UNICOM 300
(see figure 5).
Press lightly on the metal-colored closure of the mini-SIM holder and turn anticlockwise, the mini-SIM
holder unlocks and falls open. The mini-SIM must be inserted with the gold contacts facing backwards
and the angled corner upwards (fig. 8, pos. 1). Close the mini-SIM holder by carrying out the above
operations in reverse order.
Insert the SIM card as shown in figure 8, pos. 2.
After placing the mini-SIM, test the correct operation as described in chapter 5.
When changing SIM cards on the same APN, UNICOM 300 retains its IP address and does not
log in again. However, the device can be reached via GSM CSD on the new number. During a
SIM card change, SW1
must always
be pressed for at least 4 seconds to perform a re-
initialization, see also table 3.
