This is a very nice service in my opinion, Is there an option to not send it anonymously for a lower charge? Sometimes one needs to send sms'es to different parts of the world without using their phone and this will definitely come in handy.

We are implementing an option so you can add your phone number or name as 'Sendee'. When that will be implemented I can not yet confirm. It will still be anonymous in a sense that we don't keep track of your activity or who you are texting with, but you can make yourself known to whom your sending a text to.
