I thought this was impossible (without the user touching the "Send" button).
But, it seems that the Auto SMS application is able to schedule SMS to be sent without user interaction. How does it do that?
Note: this app doesn't use a server, I tested it off network.
Create your text. Tap and hold the send button (instead of just tapping it). A schedule menu pops up. Choose when you'd like to send it -- either later today, later tonight, tomorrow or a date and time in the future.
On Android: Use the SMS Auto Reply app When you first launch the app, tap the Add/Edit button to create a new rule. Give it a name, like “At Work” or “Sleeping,” and write your message in the text box. You can then go to Set Time to set the time, date, or days of the week you want that rule to be active.
Again the reason "HOW COULD THIS BE" is because Auto SMS only got away with it until Apple found out they were using their native process and now are banned from itunes. GG.
Some results from testing...confirms this app is sending normal SMS WITHOUT user interaction!
WLAN ON + GSM OFF (no reception) => the app does NOT send SMS, even after reception is back no SMS gets send. In the phone's messages log it tells "failed sending SMS"
WLAN OFF + GSM ON => the app sends SMS without user interaction (I checked my bill, and in fact a SMS got sent through the provider! - no data traffic to a server!)
So somehow this app sends a real SMS without user confirmation.
How could this be?
You cannot send SMS without user acceptance. I don't know about Auto SMS
but there are a lot of web-services in internet which can send SMS. I guess some app uses those services or uses own. But Note: nothing is free there, should pay for everything
