Calls and messages don’t always go through
I’ve had several friends tell me they tried calling me but, after a couple of rings, they lost the connection. Meanwhile, I heard no ring and did not get a missed call notice. Text messages also don’t always go through in either direction.

Big improvements
This app was horrible and barely worked about a year ago. I recently tried it again and it has been working great for texting and calling. Considering cancelling my other service after I test it some more and make sure it’s reliable.

Works as stated but 1 problem…
The problem I am having with this app is when menus say Press 1 for …. When I press 1 it is not recognized by the answering system. Pressing 2 or 3 seems to work but on several outgoing calls the 1 prompt doesn’t work. App developers, can you fix this? Thank you.
