Thank you very much for bringing me up to speed. I've only been with OTR a few months, first on the Velocity 2, a nice little device but I have more devices than it can handle and the Nighthawk has been awesome. And I just read on their website this notice they put out that they will waive the cost of the Unlock. Thanks again for all the encouraging news and I look forward to the switch to T-Mobile. I use them as my carrier and know I will get good reception here in Arkansas, anything beats the hell outta Comcast, or as Trump calls them, CONCast, he's not shy about telling the world the truth! Very good to hear from another satisfied OTR customer, take care and Godspeed!
