We at Arrivedok.mobi deployed an experimental mobile Twitter add-on application that lets you tweet from your cell phone FOR FREE even from abroad, avoiding charges for SMS, voice or data transfer.

It is available for ArrivedOK registered users only.

How to use it and save money on text and data traffic:

• First, login to your ArrivedOK account or sign-up and authorize your mobile phone to use with ArrivedOK.
• Second, make sure your ArrivedOK account is bound with Twitter in your Profile:My Blogs settings.
• Third, dial +442033550595 FREE of charge from the phone you registered with ArrivedOK and follow the instructions on your phone’s display. See below how it works.

Dial +442033550595. You won’t hear a voice reply. Your call just evokes the interactive menu you’ll see next.	You’ll see the numbered menu. Press OK, enter “1″ (no quote marks) for Twitter, and send it back.	Likewise, choose between the options that appear: (1) tweet whatever you want, (2) preview & tweet a random quotation, (3) tweet your followers about that mobile tool, “0″ to return.
For example, you choose “1> Type & tweet”. You see the usual “What are you doing?” Twitter prompt. Press OK and start typing…	… like that. Then press OK to send it. That’s it.	You’ll get a confirmation that your tweet has been sent. You can just hang up now.
