A few questions :
1. Is VoIP.ms the recommended service? Are there others that are better/ cheaper but still decent/ more recommended?
2. Is there texting too, or is it voice only? What's the interface like? (Android or iPhone-wise. Is there an app? How does it work?)
3. What are a majority of people using for data to use VoIP, and whats the data usage like? How much data do you use in an "average" month?
4. Who are you using for data provider to be able to use VoIP without Wifi?
5. Any restrictions on international usage? (frequent traveller - short, sporadic trips).
Appreciate the info!
