Good Afternoon
I've installed many OTCV for Iphone and Android without problem.
Now i have this issue With Samsung A3 2016
This smartphone mount android 6.0.1 and OpenTouch 2.20.05.2
Opentouch Voice Over IP works only without the SIM Card inserted.
I've tried with 3 brand new smartphone and the problem is the same...
Any idea to solve it?
Thanks in advance
Luca.
