IMEI
(International Mobile Equipment Identifier). 15-digit number that uniquely identifies an
individual mobile terminal device. While IMSI is specific to the subscriber (SIM card), IMEI in
specific to the wireless equipment (the modem of Bytton LTE in our case).
When the SIM card is missing, the
SIM Status window will show “error”
in the Security, IMSI, Signal Level,
Network and Registration fields.
But you will still see the version of
the 3G modem and the
IMEI
code,
since they are equipment-dependent,
and not related to the SIM card.
-
Signal Level
, displayed as two groups of two figures such as “15/30”.
The two digits indicate the level of the RF signal for the Mobile network on a scale from zero up to 30.
When the SIM card is missing or isn't registered, its status will be: “no signal”.
-
Network
: the name of the mobile network which the equipment is
registered to, as transmitted by the mobile carrier. It may also
indicate the network type: 2G or 3G.
-
Registration status
: indicates whether the SIM card is registered to the mobile network or not.
Normally, it should display “
Registration: online
”
Warning!
When the mobile module is in a call, or while it is transmitting or receiving SMS, it cannot be
interrogated about its state.
“error” messages
Thus if you click “SIM Status” while in a
voice call, you will get an error message
(ERR).
This does not mean something is
wrong, simply try again (click “Reload”)
later, when you have finished the voice
call or the transmission of SMS
messages.
