How to get the unlock code prompt on AT&T Nighthawk MR1100

I had enough of OTRmobile. They hooked me up to TMobile and then suddenly after a week, nearly no DN and Upload speeds. After a chat with OTR they assigned static IP addresses to both of my hotspots. Well one would ping Kansas which was ok not great, but the other Miami Florida. I called them they said we will unlock an HD feature on your SIM. REALLY? I am not that stupid lol. So next day ping again still Miami. I get in chat again. Their answer was we can't control where you ping ROFLMAO, wth do they think a static IP does? So I was like ok they have not a clue what they are doing and TMobile service probably in my area is just not going to work. Mind you I was fine till a Sunday and it dropped data. Did it again next 4 days and since then the pings are over 1000 and ups and downs are near 0 or are 0 on uploads. Since they don't know what they are doing, I just said ok, well I am going back to ATT for $75 a month not OTR's ridiculous $90. The big problem I have with OTR is TMobile is always cheaper then ATT yet we were paying more for TMobile then for ATT. Their per month price should of gone down not up. I suspect they are trying to make more money. Anyways I cancelled both my accounts and moved them to a new 3rd party provider who uses ATT. All is back to normal. :) 

P.S. on the unlock code. OTR stated they would unlock all devices not just those purchased from them for free. Again sounds like they have no idea what they have said or what they are doing anymore. They removed the ability to cancel auto-pay 2 weeks ago (My brother was using them till yesterday) and they added a FUP/FAP at the bottom of the page. They have gone from unmanaged network with ATT to a managed one and now you can get throttled for heavy use. They don't state what detemines what the heavy data use limit is.
