I found the Tresta service to be stable… I found the Tresta service to be stable and reliable. I was using another company for my outgoing business calls, but my calls kept getting disconnected and dropping. Tresta worked reagrdless if it was a 15minute call or an hour and a half. Thanks

Almost 25% in hidden fees Almost 25% in hidden fees. Google provides the same service for $5 per month. Contrary to the false representations made by Tresta in response to my complaint, the additional costs are not listed on their website. I would be more than happy to send them screen shots of the "pricing" page on their website. "Super Simple Pricing $15 per month". No mention of "cost recovery fees".

Very slow app Generally speaking, the service is not bad. However, the reason for three stars is the extremely slow app (at least on Android). Just opening it to check messages or make calls takes an unacceptably long time, and sometimes even becomes unresponsive. After it's open, it's very slow to respond as well. It's a pity because otherwise they offer pretty good features for a decent price.

unfortunately unfortunately, tresta as yet does not adequately replace my iphone's stock messages and phone apps. It does not audibly notify me of incoming text messages, text messages can be late or never arrive and phone calls can take too long to connect resulting in the caller hanging up or going to voice mail.

Tresta is one of the easiest most… Tresta is one of the easiest most transparent tools I've used. The amount of features is broad and the flat price for everything is amazing. When I had a chance to use their support, I found it intelligent, and useful, not outsourced "reading a script" level. Highly recommended.
