T-Mobile had attempted to mitigate the fine that the FCC had imposed on them but it seems that they were unsuccessful. The FCC has since slapped T-Mobile with a fine of $819,000 and the carrier has 30 days to pay the fine, otherwise the case would be escalated to the Department of Justice where we reckon things might get a little more sticky.
According to the FCC’s mandate, carriers are required to have a certain number of HAC devices. The number of such devices required by Tier 1 carriers, such as T-Mobile, have changed over the years, but a minimum of 10 devices or at least 50% of a carrier’s breadth of devices should offer up the M3 acoustic coupling, or seven devices or 33% of a carrier’s portfolio has to offer a T3 inductive coupling.
