WHY USE duPhone ?

* COMPLETELY FREE AND WITH NO ADS: duPhone and all duPhone features
are absolutely free and do not require any additional “in application”
purchase. Once you and your friends install the free duPhone
application, you can use it to talk and also text as much as you
want. Just makes sure all your friends get duPhone! All you need is an
Internet connection: 3G or Wi-Fi where available. On top of that,
duPhone
doesn’t contain any annoying ads.

* NO INTERNATIONAL CHARGES: It doesn’t matter where you or your
friends are, be it on the same network or in a totally different
country. You can talk for as much as you want, for free. Just make
sure your friends have duPhone too.

* NO USERNAMES, PASSWORDS OR REGISTRATION: You know your friend’s
phone number, so why bother with yet another username and password?
duPhone uses your phone number as your “identity” and lets you make
free duPhone phone calls to any of your friends that have duPhone –
using THEIR phone number.

* NO NEED TO ADD BUDDIES: Unlike applications like Skype, Windows Live
Messenger or Fring where you need to “add buddies” and have them
approve you,duPhone behaves just like a phone. Just like you dont
need to “add” someone in order to call them, you dont need to add
your friends in order to call them on duPhone. If you know their phone
number, then you know their duPhone number, and you’re ready to go!

* SOUND QUALITY: duPhone uses state of the art technology in order to
make sure the sound quality you get is much better than GSM or a
regular phone call.
