  • T-Mobile released a wireless router rebranded from the RT-AC68U.
The T-Mobile rebranded version has a custom proprietary firmware
that is modified for optimizing the T-Mobile Wi-Fi calling feature.
This router requires a refundable $25 deposit (or none if qualified) for postpaid
plan customers [$99 for retail pricing/prepaid accounts] since this is a lease.

  • Notice: If you got this router as a postpaid customer, keep in mind that T-Mobile expects
it back after you cancel your T-Mobile service or if a coverage line is disconnected
from a family/multiple line account within 45 days after cancellation/disconnection.
Failure to do so may incur a $99 non-return fee. If the router is returned damaged, $25.
[This doesn't apply to prepaid customers or if bought in retail price.]
