How Multimedia SMS Works?

With the help of Multimedia SMS feature, you can send any file below 15MB of size. This feature allows you to send an attachment with the SMS like jpg, mp3, zip, pdf, csv, etc.

The user has to upload the file and when the attached file gets loaded in Fast2SMS server, then the system provides a dynamic short link (which link to that uploaded file). The good thing about that short link is that for each SMS receiver, URL will be different. Like for one receiver, short link will be and for 2nd receiver short link will be but both short link will point to the same uploaded file.

Our bulk SMS service is the most affordable and user-friendly service, so try it once and explore a variety of new features.
