MicroCell End of Life Has Been Announced
The official end of life for the MicroCell will be at the end of this year (2017). AT&T will stop selling the MicroCell except at Corporate Stores who still have them in stock. However, AT&T will continue to support the MicroCell for an unspecified period of time next year. Of course that will mean that most of the "support" will be trying to convince customers to upgrade their phones to WiFi-C capable phones. We will still be around as usual for support questions but don't expect to get much out of AT&T.
