The ting wikipedia site says 'Ting supports devices that run on Sprint (CDMA), AT&T (GSM), T-Mobile (GSM) and Verizon's (CDMA) cellular networks. Is this true. I just checked two Verizon phones, one smart phone and one old flip phone and your compatibility checker said they were not compatible. Do any Verizon phones work?
verizon, AT&T phone support
