Sprint's towers were built for it's CDMA network running in the 1900 MHz spectrum. However, their LTE network primarily run at the 2.5GHz spectrum which has far less range/requires a different cell tower spacing. As a result, they have coverage gaps on the LTE network. If they moved to VoLTE, they'd drop a lot of calls due to the gaps, so they've primarily kept voice on the CDMA network. |
