SMS Gateway (Send SMS via URL)
This page explains how to use the SMS Gateway, which allows devices on the router’s LAN to send an HTTP GET request to the router’s SMS endpoint. The router validates the request parameters and then sends the SMS via its cellular modem/SIM.
Because GET places parameters (including message text and credentials) in the URL, the data may be exposed in browser history, logs, and intermediaries. Always use HTTPS, restrict access to trusted hosts, and avoid sending sensitive content in URLs.
1. Open web GUI Services > SMS > SMS Gateway
2. Enable SMS Gateway and config username/password to send SMS.
3. Open the web browser, use URL to use get method to submit SMS, for example:
https://192.168.8.1:443/cgi-bin/sms_send?username=user2&password=abc123&text=test%20get%20to%20send%20message&number=0123456789
Username: the username configured in SMS Gateway page.
Password: the password configured in SMS Gateway page.
Text: the SMS content.
Number: the SMS receiver phone number.
4. Using ‘%n’ as new line in SMS text, such as
https://192.168.8.1:443/cgi-bin/sms_send?username=user2&password=abc123&text=test%20get%20to%20send%20message%nthis%20is%20new%20line&number=0123456789
5. Use the URL to read all SMS messages, for example:
https://192.168.8.1:443/cgi-bin/sms_list?username=user2&password=abc123
6. The SMS gateway also supports post method to submit SMS.
