Android Telephony API Issues

Last update: April 2018


Phones with Android 5+ that still do not implement fully API 17 telephony functions

There are phones with Android 5, 6 and even Android 7+, i.e. API 21+, that still do not (fully) implement API17+ telephony functions (they implement API 1 telephony functions!), which limits drastically our app's features for those phones.

Android Dual-SIM issues

Last update: May 2016


Not all devices implement fully and correctly the Android telephony interface. If the device does not provide dual sim signal strengths to the API17+ Android telephony interface, then the dual sim functionality of our app can not work. This is not our limitation, but it is a device/firmware issue.

Non-MediaTek devices with Android < 5.0 do not support our dual SIM app functionality. It is an Android/device issue.

In Release 3.12.0 we deployed a largely updated dual SIM engine. 

If the dual SIM functionality does not work in your phone, please email us the system info/feedback from the app settings.
