Great question! At this time, there is no unlimited HD streaming option available for our pay in advance account types. If you want to have HD streaming on a pay in advance account, you would need to be on the T-Mobile One Prepaid plan and add the $3 HD pass which gives you 24 hours of HD streaming. If you are on a postpaid account, you can purchase the T-Mobile One Plus feature and enable the HD streaming forever when we add the $0 HD pass feature to your account if you want it.
