Figure 5-209: SIM Status examples (for different Romanian carriers)
.
The examples above refers to SIM cards from different carriers, with the level of RF signal is lower or
higher, having access to both 2G and 3G technologies. One Sim card has a higher signal level, but is not
properly registered – it provides just “limited service”, thus it is “offline”.

Figure 5-210: Several examples of SIM Status for the “Mobile Carrier B” provider
.
In the series of three examples above, the same Bytton equipment, fitted with the same 3G module and
with the same mobile data subscription from the “MobileCarrierB” wireless voice/data operator, is shown in
three situations, from left to the right: no signal at all (external Mobile antenna not connected) thus online
and no signal or cell indication, with good signal and registration, but data net in error, and finally with data
connection active (it show not just the network, but the 3G technologies actually available)
The status of the Sim card and mobile module is automatically read every five seconds.
The following information items are displayed:
-
Security
: “Unlocked” or “OK” means the SIM is active. “Locked by PIN” means the SIM card is asking
the PIN code to perform unlock.
As an additional security measure, the SIM card is also provided with a PUK code, requested after three
wrong PIN codes.
-
Modem Version
: it is read from the 3G+ module, displays a string such as
. or
K2_0_7_35AP,
which is very useful as information for debugging or when you need to replace the equipment.
-
IMSI
(International Mobile Subscriber Identity), subscriber's identity (SIM card identity). This is a unique
15 digits code number that identifies a mobile subscriber to the network. When the Topex Bytton LTE's
mobile module detects an active SIM card, it will query (and display) the IMSI code.
Since the IMSI code is related to the SIM, when you change the SIM card, or when a dual-SIM equipment
selects the second SIM, you will have another IMSI code.
