To improve the quality of work with Multi-IMSI and SIM cards of virtual mobile operators, we advise to follow the recommendations below.
All settings must be made on the Data Transmission tab.
¶ 1. Reduce delays on unsuccessful attempts to connect to the server
-
After a series of unsuccessful attempts to suspend the connection procedure for =
5minutes (or less)
This configuration can be done using a command sent via SMS or via the Internet from the GPS platform:
*!EDITS TRANS:ROAM(,,300)
¶ 2. Increase the waiting time for registration in the cellular network
Device firmware dated 09.03.2021 or later is required to follow this recommendation.
To update the firmware you can use DRC server or NTC Configurator by connecting with USB or remotely.
Go to the list of firmware
In the updated firmware, the default timeout for registration in the cellular network will be 180 seconds. In practice, even 90 seconds will be enough to take into account most of the delays for Multi-IMSI.
If necessary, this parameter can be edited:
This configuration can be done using a command sent via SMS or via the Internet from the GPS platform: (for example, set it to 180 sec):
*!EDITS TRANS:SIMPRIOR(,,,,180)
NTC Configurator v3.1.6 and older does not work with registration timeout setting.
In this situation, the parameter can only be configured using a command via SMS, USB, Internet (from the GPS platform).
BUT if you change the settings after configuring this parameter using NTC Configurator v3.1.6 and older, then the device will set the default value of the parameter (180 sec).
If you still have questions about working with the hardware, please contact our Technical Support Team.
