Don't use Tresta if you have any need for a backend to process the backend information it produces I have worked with Tresta's sister company - Hosted Numbers - for over 10 years. 100% happy with Hosted Numbers. I tried Tresta because I needed my tracking phone numbers to be text-able. The problem is that Tresta has almost NO reporting functionality. That is, I have to manually process the all the data for the responses to the Tresta phone / text numbers I use which basically makes Tresta useless to me. I cannot afford to use Tresta without an adequate reporting backend like Hosted Numbers has. With Tresta one CANNOT pull in the data to an Excel spread sheet; you have to record each communication manually which is insane. Tresta surely is losing bucket loads of business because of the non-existent reporting back end. I WANT to use Tresta very much but they do not seem to have any intention or interest in building out the functionality of their back end. This must be done if they want to grow or even stay in business.

The app gets hung up sometimes and… The app gets hung up sometimes and freezes. Also, I can't send outgoing pictures. I can receive them but I need to be able to send them and instead I have to use my personal cell phone number to clients which defeats the purpose at times.

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.

1 star edited to 3 star due to customer service rep. I'm editing my review from a one star to a three just because of the quick response to resolve the problem that I am having. They haven't necessarily fixed the problem yet, but as a business owner I can definitely respect the fact that they have already reached out to me and that they stand behind the product and they are trying to find out why I'm having such difficulties. I was told they would be reaching back out to me to let me know what they find.

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.
