To put a message on Upingme so that everyone with a mobile phone or a web browser can read it, send a text with the letter 'U' followed by a space and your message for FREE to: +41-79-381-6010 (Upingme doesn't charge you for posting, your mobile provider might) just like this:
U I have a new and boxed Dualit toaster to sell with guarantee- an unwanted gift. I will take €23 cash. You can collect from my Rome office 9 - 5. msg me!
The system will text you confirmation, which will contain the magic number for your new message and your password. You must then tag your message using the magic number so that people will be able to search for your message.
