Minimizing risk of SIM blocking

  • Using CallerID Whitelist to only allow know good numbers to dial-out. That way minimizing the risk that Mobile operators will find out about SIM cards used for GSM Termination.
  • Blacklisting numbers which behaves in suspect manner
  • Placing GSM gateways in the populated areas: supermarket, stadium, etc
