How do I mass delete all my messages (SMS)

[wannabelean]

Have about 4 years of txt messages and would like to delete them all.

You can't delete all messages at once. You have to delete all conversations one by one manually.

Yeah, no need to do it message by message, but you'd need to do it conversation by conversation.

Yeah, not sure if you need clarification, but just slide the conversation to the left (from the list of all conversations) and it will reveal a delete button. Click that, and you're done.
