Hi, I want to share my new observation, that the app Satellite by Sipgate works with 4.4.0.72. (This was not possible with 4.4.0.68. I installed Satellite via Aurora-Store).
So you get a second mobil-number without using a second sim-card; perhaps this could help some people, who have actual problems with their second sim-card.
For my professional purpose, it is useful to have a second telephone number, without sharing my privat number.
100 minutes for outgoing calls are free per month, for incoming calls there is no restriction AFAIK.
Regards
