I understood from our distributor that T-Mobile Carrier Aggregation does not (yet?) work in the LTE-Advanced models.
The problem is the frequencies/bands that T-Mobile uses?
Is this something that can be fixed in a firmware update, or will this mean a new LTE-Advanced module will be needed (which probably means a new hardware revision will be needed)?
One of our customers is very interested in a LTE-Advanced MAX HD2’s and MAX HD4’s for SpeedFusion, but they only use T-Mobile.
The given list by @TK_Liew refer to the available LTE band for T-Mobile. It’s referring to Primary Band + Secondary Band ( Example: 2 + 2 for Carrier Aggregation ). Hope this explain your concern.
