“simple to use”

Pros

It just works consistently which has been one of the biggest advantages for us. The phone support is outstanding and the tech support team has also been excellent whenever needed. On top of that it's simple to use and easy to configure.

Cons

The main downside is the cost of the basic plan. Porting has also been a hassle although I haven't had to deal with that in the last few months.
