Charging of "Intra-network and "Inter-network Calls

Mobile network operators may impose different rates on "intra-network and "inter-network calls. This also applies to non-voice services such as Short Message Service (SMS) and Multimedia Message Service (MMS). In general, "intra-network calls refer to between subscribers of the same network operator while "inter-network calls are those between subscribers of different network operators. Different operators may apply different deduction mechanisms on free "intra-network and "inter-network minutes. You are advised to check the details of the charging plan of your network operator.
