How to set Now SMS as default SMS app? I have Nexus 7 2013 LTE with Android 4.4.2. I want to set Now SMS as the default SMS app but I have not been successful. After choosing it as the default, the popup is still shown next time I start Now SMS!

Can anyone help me out?
Go to Settings, and under the "Wireless &amp; Networks" section tap More....  There should be an option called Default SMS app.  Tap it, and select the "Now SMS" app.  You should be all set now.

[Edit]:
Apparently, Google deliberately disabled the SMS functionality on cell-enabled Nexus 7 tabs (both 2012 3G and 2013 LTE tablets are impacted) with the 4.4 update. The recommended solution is to flash a custom ROM that re-enables the setting.  Keep in mind that this will require unlocking the bootloader, which may void the warranty.
