Taxt Messaging company

Does anyone use Trumpia.com for text messaging i was looking at them online and was just seeing if anyone uses them and how is there experience with them or what company do you guys use for text messaging? Trumpia is charging $50.00 for 1,000 text messaging in a month with them being rolled over 2 keywords max contacts of 5,000. they sound good compared to others i have seen. thanks
