Read this before you assume "anonymous" means untraceable
A shared or pooled sender ID keeps your personal phone number off the recipient's screen, and sending over an API means your own mobile carrier never sees the message pass through your plan. Those are real, specific protections, and they're the whole reason this class of tool exists.
They are not the same thing as untraceable, no-logs or encrypted. The destination carrier has to see the full message and the recipient's number to deliver it at all — that is how SMS routing works, on any service, with no exception. Delivery logs exist somewhere on that path, and lawful process (a subpoena or warrant) reaching the sending platform or the destination carrier can reach those logs. SMS as a protocol has never supported end-to-end encryption; every text is plaintext to the carriers that route it. Anyone telling you otherwise about any SMS provider is not being accurate.
This matrix is a limitations page, not a pitch. For the practical mechanics of how sender pooling actually works, see how anonymous sending works.
