Paula-Jimmy, Are you having an issue with exchanging the device? Have we done any basic troubleshooting? Since the devices are currently out of the 30 day exchange window, we aren't able to swap them out for iPhones but we can take a look at the drop call issue.
Paula-Jimmy yes tier 2 exists. If you send me a private message with your full name, account number (residential) and your address, I can take a look into your ticket.
