Users are reporting on the Sprint Community forums that their phones are able to connect to a WiMAX signal, but no data is being transferred. Others are reporting that the issue stretches from the north of Boston to Rhode Island, and apparently Sprint has only recently acknowledged that there's an issue at all. In any case, some users are being offered service credits for the time that they have been without 4G, so it wouldn't hurt to give customer service a call if you're in the Boston area right now.
Are you currently being affected by this outage? If so, how has customer service handled your complaint?
[Sprint] Thanks, Peter!
