Xoxzo is the telephony web API platform for web developers.

The predecessor to Xoxzo, EZSMS was released to cater to the communication needs that rose from companies and independent developers due to the frequent changes of mobile email address due to MNP in Japan. We leveraged our knowledge of SMS delivery from our experiences of running SMS delivery services since 2007, and this has allowed companies and developers to incorporate SMS easily to their smartphone applications and services.

EZSMS provides you unique functionalities such as One Time Address (OTA) notifications, DialSMS and sending from the web browser via CSV uploads or a simple form.
