Once again, I am posting in general, and not to your specific requirements.
Some may need a mixture of different products. Eg. Viber for free voice and video, and another product for a local country number. Some are happy with credit / minutes, while some need an unlimited subscription because they either make many calls, or talk a long time, or both.
Each to there own.
Can you put forward a product that is closer to Skype than Viber, as a one stop shop, the way Skype is?
Yes, Viber is missing a local number feature. I believe they used to offer it but stopped offering it. They may offer it again with the shutting down of Skype.
