Send welcome sms via API to newly registered user via signup form

You want to add your code through a hook. So your code should look more like this

function send_sms_after_registration( $user_id = 0 ) {
        // Authorisation details.
        $username = “myemail@gmail.com”;
        $hash = “66ade0f0c30253145b390866621d163eccbd52181466b0205aee7ba2e6d9ea82”;

        // Config variables. Consult http://api.textlocal.in/docs for more info.
        $test = “0”;

        // Data for text message. This is the text message data.
        $sender = “TXTLCL”; // This is who the message appears to be from.
        $numbers = “910000000000”; // A single number or a comma-seperated list of numbers
        $message = “This is a test message from the PHP API script.”;
        // 612 chars or less
        // A single number or a comma-seperated list of numbers
        $message = urlencode($message);
        $data = “username=”.$username.”&hash=”.$hash.”&message=”.$message.”&sender=”.$sender.”&numbers=”.$numbers.”&test=”.$test;
        $ch = curl_init(‘http://api.textlocal.in/send/?’);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        $result = curl_exec($ch); // This is the result from the API
        curl_close($ch);
} 
add_action( 'um_registration_complete', 'send_sms_after_registration', 12, 1 )

I am not familiar with the API but here are few suggestions. Use wp_remote_post instead of CURL. You can use the $user_id with the function get_user_by to get user details or pull what you need from the user meta table.
