Verizon Corp
Is know for being very picky
The device has to be recognized as being Verizon branded, before it can be activated on Verizon's network
Just buying a vzw lte SIM card and sticking it in a Tho branded device will not work
Never mind the fact that two of the lte bands are the same
Then there is the problem of non matching 3G technology, for when lte is not available
This is why, if you search Google and eBay for hotspots
You will see some Sprint devices reprogrammed for Verizon
But i have not seen any Tmo devices adv for Verizon
Or Verizon devices adv for Tmobile
I don't know how picky Tmo towers/Corp is about device branding
But again is the same technology problem, if the Tmo SIM works only two LTE bands will be usable, and no 3G service, you could find yourself with no service for the hotspot, even where a phone has a strong Tmobile signal
