Phone calls are usually more costly than text messages and certainly more disturbing. Texting allows the recipient to get information without having to write things down, or interrupt a call in progress; it is a great way to eliminate time wasting call backs
Text messaging can get through even when voice can't. Many people travelling will go in and out of coverage areas; text messaging can easily be received when passing through even marginally covered areas. Think how frustrating it is calling a cell phone and being unable to get through, having the recipient try to call you back and getting cut off!
Texting leaves all the important info with the recipient Phone Number, Names, Address and description, plus you have an archive of everything you sent (much better than voice calls)
Not all cell phone users have email or if they do, it's just for receiving messages and when mobile it is far more costly than texting.
Texting is used by many companies like the old pagers were, with an escalated attention to action over phone calls or email. This makes this service ideal for service dispatch and sales dispatch.
