You can't send an SMS automatically from iOS, you can present the user with the SMS view and pre fill the SMS body.

You will find more on how the use the MFMessageComposeViewController here: http://developer.apple.com/library/ios/#documentation/MessageUI/Reference/MFMessageComposeViewController_class/Reference/Reference.html

- (void) sendSMSCode:(NSString *)smsCode {
    MFMessageComposeViewController *viewController = [[MFMessageComposeViewController alloc] init];
    viewController.messageComposeDelegate = self;

    [viewController setBody:smsCode];
    // Replace with the number to send the SMS so
    [viewController setRecipients:[NSArray arrayWithObject:@"+123456789"]];
    [self presentModalViewController:viewController animated:YES];
    [viewController release], viewController = nil;
}

#pragma mark - MFMessageComposeViewController methods

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {

    [controller dismissModalViewControllerAnimated:YES];

    if (result == MessageComposeResultFailed) {
             // handle the error.
    }
}

This is the extension for your question regarding Encoding/Decoding:

#import <Foundation/Foundation.h>


@interface Base64 : NSObject {

}

+ (void) initialize;

+ (NSString*) encode:(const uint8_t*) input length:(NSInteger) length;

+ (NSString*) encode:(NSData*) rawBytes;

+ (NSData*) decode:(const char*) string length:(NSInteger) inputLength;

+ (NSData*) decode:(NSString*) string;

@end




#import "Base64.h"


@implementation Base64

#define ArrayLength(x) (sizeof(x)/sizeof(*(x)))


static char encodingTable[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
static char decodingTable[128];

+ (void) initialize {
    if (self == [Base64 class]) {
        memset(decodingTable, 0, ArrayLength(decodingTable));
        for (NSInteger i = 0; i < ArrayLength(encodingTable); i++) {
            decodingTable[encodingTable[i]] = i;
        }
    }
}


+ (NSString*) encode:(const uint8_t*) input length:(NSInteger) length {
    NSMutableData* data = [NSMutableData dataWithLength:((length + 2) / 3) * 4];
    uint8_t* output = (uint8_t*)data.mutableBytes;

    for (NSInteger i = 0; i < length; i += 3) {
        NSInteger value = 0;
        for (NSInteger j = i; j < (i + 3); j++) {
            value <<= 8;

            if (j < length) {
                value |= (0xFF & input[j]);
            }
        }

        NSInteger index = (i / 3) * 4;
        output[index + 0] =                    encodingTable[(value >> 18) & 0x3F];
        output[index + 1] =                    encodingTable[(value >> 12) & 0x3F];
        output[index + 2] = (i + 1) < length ? encodingTable[(value >> 6)  & 0x3F] : '=';
        output[index + 3] = (i + 2) < length ? encodingTable[(value >> 0)  & 0x3F] : '=';
    }

    return [[[NSString alloc] initWithData:data
                                  encoding:NSASCIIStringEncoding] autorelease];
}


+ (NSString*) encode:(NSData*) rawBytes {
    return [self encode:(const uint8_t*) rawBytes.bytes length:rawBytes.length];
}


+ (NSData*) decode:(const char*) string length:(NSInteger) inputLength {
    if ((string == NULL) || (inputLength % 4 != 0)) {
        return nil;
    }

    while (inputLength > 0 && string[inputLength - 1] == '=') {
        inputLength--;
    }

    NSInteger outputLength = inputLength * 3 / 4;
    NSMutableData* data = [NSMutableData dataWithLength:outputLength];
    uint8_t* output = data.mutableBytes;

    NSInteger inputPoint = 0;
    NSInteger outputPoint = 0;
    while (inputPoint < inputLength) {
        char i0 = string[inputPoint++];
        char i1 = string[inputPoint++];
        char i2 = inputPoint < inputLength ? string[inputPoint++] : 'A'; /* 'A' will decode to \0 */
        char i3 = inputPoint < inputLength ? string[inputPoint++] : 'A';

        output[outputPoint++] = (decodingTable[i0] << 2) | (decodingTable[i1] >> 4);
        if (outputPoint < outputLength) {
            output[outputPoint++] = ((decodingTable[i1] & 0xf) << 4) | (decodingTable[i2] >> 2);
        }
        if (outputPoint < outputLength) {
            output[outputPoint++] = ((decodingTable[i2] & 0x3) << 6) | decodingTable[i3];
        }
    }

    return data;
}


+ (NSData*) decode:(NSString*) string {
    return [self decode:[string cStringUsingEncoding:NSASCIIStringEncoding] length:string.length];
}

@end

Hope this will help you.

Sending a in-App SMS is very similar to in-App email, but with some little differences. Use MessageUI Framework for sending in-App SMS.

-(IBAction) sendInAppSMS:(id) sender
{
    MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
    if([MFMessageComposeViewController canSendText])
    {
        controller.body = @"Hello from Mugunth";
        controller.recipients = [NSArray arrayWithObjects:@"12345678", @"87654321", nil];
        controller.messageComposeDelegate = self;
        [self presentModalViewController:controller animated:YES];
    }
}
