Template:FMB GSM Operators settings

FMB120 can work in different modes (use different settings) according to the operator list defined. Operator list is used for Data Acquisition Mode switching (see Data acquisition settings section for more details). Modes are changed based on GSM operator FMB120 is connected to.

If roaming operator list is left empty, FMB120 will automatically detect home operator. If home operator will be written to roaming operator list any part, it will be detected as home operator, not roaming. Any not written operator in roaming operator list (not home operator) will be recognized as unknown operator and FMB120 will work in Unknown mode (make sure it is configured to allow data sending – GPRS context is enabled).
Operator Blacklist - if user wants that FMB120 do not connect and work with a particular operator it must be written to Operator BlackList. Total 50 operators can be written to this list.
Operator Blacklist working: operator search procedure is initiated as normal every 15 minutes and tries to connect to an operator with the strongest signal. It will prioritize operators which are specified in the operator list. If no operators from the operator list are available, the device will try to connect to an operator from the blacklist. If device connects to operator from black list – best operator search procedure is initiated instantly. During the time when device is connected to Black list operator - no GPRS connection would be initiated and no data would be send via GPRS. The ability to send SMS commands to the device remains. If no suitable operator is found on both lists, the device will try to connect to a remaining available operator with the strongest signal.

In SIM2 Roaming/ Home Operator list home operator must be added to the any part of the list that functionality works correctly.

FMB120 have possibility to have inserted in them two SIM cards. GPRS settings and Roaming Operators can be configurd separate for SIM1 and SIM2. In SIM2 Roaming/ Home operator list home operator must be added to the any part of the list that functionality works correctly. Dual SIM operator search functionality works like that: SIM1 and SIM2 home operators have highest priority: When device is connected to home operator - manual roaming operator search is disabled. When device is disconnected from home operator - operator search procedure is initiated as normal every 15 minutes. SIM1 Roaming operators list has higher priority then SIM2 Roaming Operator list. When device finds new operator from SIM1/SIM2 lists – it switches to new SIM according to list and connects to new operator.
