{{{model|FMB640}}} is able to operate in DUAL SIM switching mode to minimize the bill accounts for
GSM/GPRS services. To use this mode, 2 SIM Operator list enumerated value must be chosen for
FMB640 can be used with one SIM.

SIM1 card has higher priority than SIM2. For one SIM
card using it must be placed in SIM1 slot for FMB640 to switch minimum times.
If SIM card is inserted into SIM 2 slot and 1 SIM operator list mode is used, FMB640 will
work normally, but there will be more switching activities. In addition, APN settings in GPRS
should be entered for SIM 1 and SIM 2 to avoid not sending records over GPRS.

SIM 1 and SIM 2 APN settings are set in the GPRS tab (Figure). Information about APN and
authentication type should be provided by your GSM operator.

Two SIM cards use algorithm is shown in the diagram below :

* '''Home Network'''

{{{model|FMB640}}} gets possible operator codes list from the network and compares them with the operator codes
inserted in Home profile’s list. At first, it tries to connect to SIM 1 Home Operator, if operator is
unreachable; the device switches to SIM 2 slot and tries to connect to SIM 2 Home Operator.
When the connection procedure is successful, FMB640 stays connected to the available
Home operator using the SIM card, which was inserted for and works according to the Home
profile parameter settings.
If none of the Home operators could be connected with, FMB640 switches to the SIM 1
card tries to connect to its roaming operators from SIM 1 Roaming profile.
