The short message service (SMS) is enabled for gateway restart and manual dialup
via SMS messages. Some gateways can receive alarm information in the SMS
whitelist.
Method for controlling gateway restart and manual dialup via SMS messages
Click "Services >> SMS" and check "Enable". In the "SMS Access Control" bar, set
"ID" as required, select "permit" for "Action", enter the phone number, and click
Apply & Save. When you activate the dialup port via SMS, after the configuration
is completed, you can send the reboot command to restart the gateway by using the
mobile phone number, or send the cellular 1 ppp up/down command to make the
gateway redial or interrupt the dialup.
