"overpriced"

The service provided by this company is overpriced. Especially if you need incoming SMS they will charge you for it a lot of money. Other companies provide free incoming SMS and don't charge you, but even if you only send SMS it will usually cost you 2x as much comparing to other companies like Plivo. Their support is definitely better than of Plivo, but I would not recommend to use Plivo or Twilio.

"Excellent Service"

By far the best service I've found for sending SMS and phone services through my site. Easy API and simple and easy to use admin interface.
