Pretty Good Works as intended with a few minor glitches. Please note, I managed to get around that annoying '-24' error by uninstalling and reinstalling the app. It was the same error another app of theirs had.
Update error Been trying to update this for a week already, but it keeps saying unable to install, error code 24.
keep show Unknown error code .....please fix
Great!! Work smooth in Go SMS pro. This app won't appear on the menu. U have to go to Go SMS pro's basic setting, then choose 'language' to change it to 'traditional Chinese'. There is a button to let u choose traditional Chinese as ur Go SMS pro's language. If u haven't downloaded this app, it won't let u choose and will lead u to play store to download this app
