Nymgo

With Nymgo, you can call anywhere in the world for a small fee, making it a handy app for keeping in touch with your friends no matter where they live.

From this virtual phone you can dial phone numbers to make calls, send text messages, and create an address book. Talking to anyone anywhere in the world is simple, fast, and effective and the connection quality usually good.

With Nymgo you can call India, Bangladesh, Brazil, the Philippines, Mexico, China, Egypt, Germany, Nigeria, Kenya, Indonesia, or anywhere else. It has a very practical interface with a world map that shows the corresponding phone number prefixes.

With Nymgo, you don't have to worry about roaming charges, and all the rates are much lower than what you'd find with other VoIP telephone services.

Undoubtedly, though, the best thing about the app is that you can get Hello Points to trade in for real money and make free calls. How? By inviting your friends to join Nymgo, among other things.
