title: Link that will "preform" an SMS on android phone
body: <p>Im building a service that will send an invitation to an event through a WhatsApp group using whatsapp API.</p>
  <p>Of course, it will require me to interact with the request to select the group and so on, which is OK, but there is no way (without expending money) for my app to &quot;read&quot; who will join.</p>
  <p>I though in sending a link, which on tap, will generate an request on the guest to send me back an SMS, and then my app to &quot;listen&quot; and generate a database of those who agree to be in meeting (my app later will send another message to the group to confirm o cancel the meet according to the amount of people who get involved).</p>
  <p>I think i can ask the people to send, but if i ask them to write the sms, they will not do it (lazy people).</p>
  <p>There is a way i can write a link like &quot;sms:myphonenumber?ImIn!&quot; to send, so the device will build the SMS for them?</p>
  <p>I know from a web u can do something like href:...., and will do the work for them, but not sure otherwise.</p>
