Get SMS+Tether enabler [Xposed] old version APK for Android
Enables SMS+Tethering on Nexus 4,5,6,7,9,10 and Moto E, G and X devices (4.4+)
Enables SMS, Tethering/Hotspot, USSD codes, and SIP calling feature on Nexus 4, 5, 6, 7 (2012: GSM and 2013: LTE version), 9 and 10 and Moto E, G and X running Android 4.4+ using the Xposed Framework (http://forum.xda-developers.com/xposed/xposed-installer-versions-changelog-t2714053).
You need to have the Xposed Framework installed in order to make this app/module work!!!
Install the Xposed FrameworkInstall this moduleActivate the module in the Xposed module managerReboot your deviceEnjoy the freedom ;)It is not necessary to install this app on a device already having the SMS and tetheing/hotspot functionality. This mod might also work on non-Nexus or non-Moto devices, with a proper radio (2G, 3G, 4G) but with disabled SMS or with disabled tethering/hotspot options (by the vendor/provider).
I would appreciate it if you could rate the module after trying it out and maybe leave a comment to explain what you think of it. Maybe you also have a feature request.
The tethering function for example was such a feature request.
