(this is a generic process for all Networks and finer details may differ between networks).  

  • Insert the SIM card in a normal phone to receive OTP with web portal and app registrations setups.  
  • Remove the SIM’s security pin. 
  • SIM will now be activated on the network belonging to the SIM provider i.e. MTN, Cell-C etc.

USSD Settings Explained:  

USSD (Unstructured Supplementary Service Data) is used to obtain the Airtime information. Each cellular network uses different commands and the return message may change from time to time.  

The following commands can be used if the Airtime and SMS value is not correctly displayed. All the commands are not used if the unit is configured as a SMS unit.  

Only 60 characters can be sent to the unit via SMS, the commands can be sent in batches, the commands and settings are case sensitive.  

If no correct value was received “NA” will be displayed meaning the value was not available at that time.  

The following networks is preprogramed into the unit. MTN, Vodacom, Cell C and Telkom. If a different Network is used the Network name will be displayed as Unknow and custom settings will be used, follow the same steps as one of the existing networks.
