LTE seems to cause less of a load on their network. I assume so because ATT has a higher limit on LTE, and cause verizon has been giving, grandfathered in, unlimited users, a free LTE phone. Well, those with very high data usage.
This makes me assume that they would want the same for the usage of MVNOs. That would cause them to have a ST LTE option.
These may have been a series of compounded assumptions (which is never a good idea), but i wish someone would look into it
