Textmagic is a no brainer ! set & forget, it just work

We needed and actual SMS gateway to implement dual factor authentication AND to send actual emergency notification backed by text messages.
The interface is easy to understand, and setting up email transport rules was a piece of cake.

It is very affordable. We only use it for internal company communication (no marketing campaign), and so far, it never failed to deliver.

This is a very good service, that is worth a try. Also, the provisioning of the account is made convenient, with regular usage reports.

Happy with it !
