These parameters are all that is needed to be able to log in GSM/GPRS network. One has to
remember that modules with basic configuration can not send any information. Therefore,
after verifying that module logs in to GPRS network, one has to perform full configuration
of module parameters enabling all full intended functionality of the module.
6.3. Inserting SIM card
One of the fundamental conditions for proper operation of the module is inserting a
SIM
card enabling module to send SMS and/or packet data in GPRS network.
The best way to do it is when the power supply disconnected. Theoretically the SIM card
may be inserted into the module before the first configuration is performed, but note that
two attempts of entering wrong PIN code the cause module to stop attempting to log into
network. Should this happen, the module has to be unlocked.
NOTICE!
Earlier models of MT-101 do not have the function preventing triple
attempt of inserting wrong PIN code resultingn permanent locking of
access to SIM card and subsequent permanent locking of module. Should
this happen, the SIM card has to be unlocked using the PUK code.
The details of the procedure unlock the card is described in chapter
Problem solving
Insert
SIM
card in cradle and slide it into the slot as depicted below until the gentle click is
heard.
Properly inserted
SIM
cards secure reliable connection with module's terminals.
6.4. Start up
After performing the first configuration and inserting SIM card, proceed to start up. Switch
the power supply off and on again to reset the module.
NOTICE!
If the SIM card was inserted to the module during first configuration
resetting the module is unnecessary as every writing of new
configuration forces RESET of the module.
Well/configured MT-101 module logs into GPRS network within 20 -30 seconds. The login
sequence is displayed by diagnostic LEDs at the front panel of the module. Explanation of
sequence is described in details in LED signaling chapter.
In case of difficulties when logging into GPRS, verify configured parameters and pay
attention to LEDs indicating GSM signal level.
