This means that IP sensors and other HWg devices connected to the same network can send alert messages through HWg-SMS-GW. A huge advantage is then the use of only one SIM card for sending alert SMS messages from all devices. It is not recommended to use a pre-paid SIM card, on the other side a post-paid card works reliably without any stops and problems.
