Only android people fuss with third party apps because their phones can’t reasonably send messages by default.
IOW, SMS is cross-platform. Whats the issue?
Unlike modern messaging platforms, SMS has no:
- guaranteed delivery
- read receipts
- proper support for group chats (MMS adds this, but the implementation is poor compared to modern platforms)
- support for multimedia (again, MMS added this, but support is poor)
- support for replies
- support for reactions
- support for any kind of encryption
- support for typing indicators
- ability to work independently of an active cellular connection
If SMS works for your needs, and you have no issues with it, that’s great. Ultimately, SMS does work, but many users rightfully expect more of a messaging platform at this point. There are real benefits to users from upgrading to a more modern system.
I am fine with using SMS, and it has always served me well.
