Advantages of service SMS

• The voice channel is completely kept, the transfer (reception) of SMS messages takes place in parallel with usual telephone conversation.
• Transfer (reception) of SMS messages is possible in case of staying in a zone of bad spredding of radiosignals. In this situation outgoing (incoming) telephone connections are followed by refusal.
• Stable work in conditions of an increased load of GSM network during daily peak loadings. Automatic delivery of SMS message in the moment of entering by the mobile object a cover zone of GSM network.
