ID: 33499551 is the bes ive encountered. You can see some example codes to send SMS here:

or you can send a POST or GET query to with the following values:

    A flag to switch on/off debug information.
    View debug information.

    If set to 1, this will return 'info' in JSON format.

    This is the test mode. If test=1 then messages will not be sent and credits will not be deducted.

    The text message body. This can be up to 612 characters in length. A single message is 160 characters, longer messages are 153 each (2=306,3=459,4=612). You can insert any merge data into this message from your database before submitting to Txtlocal. To insert a newline character use %n.

    The "From Address" that is displayed when the message arrives on handset. Can only be alpha numeric or space. Min 3 chars, max 11 chars.

    Your username.

    Your password.

    A comma separated list of international mobile numbers. Each number must be PURELY numeric, no + symbols or hyphens or spaces. The numbers must start with the international prefix. In UK this would be 447xxxxxxxxx. View international prefixes.

    This is not mandatory. If set, you can send a WAP PUSH (mobile internet bookmark) to a mobile phone. Simply set to a valid url.

    This is not mandatory. If set, you can record a custom ID against the the message batch, which will be passed back in the delivery receipt.

    This is not mandatory. If set, you can send to a precreated group. You can get the required group ID from the REPORTS section of the control panel. Duplicates and optouts will be removed.

    This is not mandatory. Alternate receipt URL. Instead of using the receipt URL in the Txtlocal Account Settings, receipts will be sent to this URL.

    This is not mandatory. The scheduled message date/time. In the format YYYY-MM-DD-HH-MM-SS (e.g 2008-03-28-14-56-00). Scheduled messages can be viewed and deleted via your Txtlocal online account.

    This is not mandatory. The time at which you wish the message to expire if it has not been received by the phone (i.e. Phone out of signal range or turned off). In the format MMDDHHmm (It cannot be greater than 48hours in the future).

Heres the price list for pre-buying SMS credits.

according to their document provided with this component:

"This component is free to download and use. You can distribute this component with your own SMS enabled applications"

So I think that, correct me if I'm wrong, you can use it.

The best is maybe to contact them to be sure?
