Ting is dropping support for GSM-only phones and T-Mobile, switching to Verizon – By Corbin Davenportandroidpolice
Ting Mobile has been a popular MVNO carrier for years. Much like Google Fi, it's oriented towards people who don't use a lot of cellular data, with the option to mix-and-match tiers for minutes, texts, and data usage. A major strength for Ting has been the ability to use either a GSM or CDMA network, but that will soon go away.
