You may know that we do have an app available, but as the app is a cut down version, if you have multiple Groups stored online, the mobile app is probably not appropriate.
But you can certainly login and send SMS campaigns via your smartphone. I personally have a Galaxy Note2 with a nice large screen..I will admit it can be a little bit snug but it certainly works fine (as does iPhone and iPad).
One thing I have noticed though is that the default browser on Android now doesn't seem to work with SMS Express (it used to!), but Chrome browser certainly does, so please download Chrome for your Android device. Any pop ups will appear down the bottom of the screen (such as your SMS message preview that pops up) so make sure you scroll down to view this.
Any questions please call 1300 668 287
