In a new recently posted support page, Sprint has addressed the native coverage loss in areas of North Dakota, Wyoming and Montana as a result of the divested former Alltel markets being purchased by AT&T and subsequently converted.
As a result of the change, what was once native voice and data coverage is now roaming coverage and subject to Sprint’s roaming rules limiting voice to 800 minutes and data to 300MB, with the change severly affecting those customers currently under contract and living in those areas.
