Google has announced it is extending the availability of its Google Voice telephony service to anyone in possession of a .edu email address (previously, Google Voice was available only through elusive invitations). Google Voice offers features such perks as free text messaging, low international calling rates, SMS-to-email, and voicemail-to-text transcriptions, all of which could be particularly useful to peripatetic students. To sign up, simply send a request to Google from the linked page using your educational email address, and an invitation will be sent to you within 24 hours. Google Voice is currently available only to people in the United States. follow link
