Pre-ordered call (callback)

SMS callback is usable anytime and anywhere. It is advantageous e.g. if you are abroad in roaming. You will send only one roaming SMS to call with any number e.g. from your hotel room. You can use this way for cheap calls from phonebooths abroad (with visible phonebooth number).
