2. Search for "SMS Call" in the search bar of the browser, and click Enter to enter the search.

3. At this time, the browser will jump to the related interface of SMS calling and click "SMS calling".

4. After clicking, a short message call processing interface appears, with prices, products and effective methods on it. Just click the blue button "Deal with it now", which usually takes effect immediately.
