SMS for messaging between applications

Question

What would be the issues or advantages to using SMS messaging for inter-application messaging? more or less reliable than http? etc.

Answer 1

• HTTP is time-tested for inter-process communication, it's recilient, etc.
• SMS are subject to carrier fees, carries arrangement, international inter-carrier agreement
• There's usually more latency in SMS
• Many SMS never get delivered or get delivered late
• HTTP is based on TCP/IP, the foundation on which modern internet communication relies.
• SMS in intrinsically less secure for corporative communication and additional infraesctructure must be provided to provide enterprise class security.
• SMS could potentially have more international boundaries than HTTP.
• As mentioned by @jörg-w-mittag, SMS is ~100000 times more expensive than HTTP.

On the bright side I'd say that in areas where there's no data coverage, a SMS based message queue could be an option.
