Why is this? SMS is still the most ubiquitous, far-reaching messaging channel in the world and will remain so for quite some time. While there are a growing number of non-SMS messaging/social media options (WhatsApp, Snapchat, Facebook Messenger, WeChat, and many more), virtually all of these require both the sender and receiver to be using the same solution. This leads to significant fragmentation – notwithstanding that many of these non-SMS chat apps are and will become significant A2P channels going forward. Otherwise, SMS continues to show strength in that regard.
