This whole unlock situation has been a monumental pain in the behind for a LOT of people. And having to play games giving crypto-currency to a bunch of foreign hackers and hope they actually provide what you need to make your device usable is repugnant.

At this point I know of people that STAYED with a provider that used AT&T because getting their device unlocked was so onerous.

In theory, My Nighthawk is unlocked, but since I'm not connected to any network with the Nighthawk right now - I got the T-Mobile Sim from OTRMobile while I was still a member but the repeatedly promised Static IP was never provided and eventually I cancelled and went elsewhere.

But, the whole OTRMobile situation was a good learning experience about trusting any of these Internet snake-oil salespeople.
