SMS To open the SMS application, just use the sms: protocol in your URL:

NSString *stringURL = @"sms:";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

You can specify a phone number, but apparently not a default text for your message:

NSString *stringURL = @"sms:+12345678901";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
