VoIP.ms SMS is an Android messaging app for VoIP.ms that seeks to replicate the aesthetic of Google's official SMS app.
Synchronization with device contacts
Comprehensive support for synchronization with VoIP.ms
A number of people use VoIP.ms as a cheaper alternative to subscribing to a voice plan for their mobile devices.
Unfortunately, this can make sending text messages rather difficult, as the VoIP.ms SMS Message Center is clearly built as a diagnostic tool for use in desktop browsers, not as an easy way to send and receive messages on a mobile device.
VoIP.ms does provide a mobile version of this interface with an improved UI, but it still lacks important features that are only possible with a dedicated app.
