I was able to sign up today but I will be getting the MiFi8000 hotspot which is 4G, they still haven't been able to get a sim card that will work with the MiFi200 5G. They have the MiFi8000's in their inventory. Only bad part about the MiFi8000 is that it does not have T-Mobiles Band 71, hoping they will let me change hotspots out when they get the MiFi2000 work. Good thing about the MiFi8000 is that it has TS9 antenna ports so you can use a MiMo antenna which is sometime better that a cell booster. I should have my unit by Oct.25th and I will give an update once I get it up and running. My back up to this unit will be my T-Mobile S20 and the Magenta Max 5G Plan that gives me 40GB of hotspot and unlimited prioritized data that I can mirror to my TV, tablet, or computer.
