Can I use Blackphone on Verizon or Sprint in the US?

Last Updated: Aug 28, 2014 05:54PM UTC

No. Verizon and Sprint are fundamentally still CDMA carriers, although they are deploying LTE as 4G technology, which is supported by Blackphone.  Even once "Voice-over-LTE" is fully deployed, there are significant barriers, including:

  • Blackphone's chipset does not support "Voice-over-LTE"
  • Blackhpone's radio does not support the required frequencies
  • In poor coverage areas without LTE, Blackphone would not work at all since it can't fall back to CDMA

We have no plans for a CDMA version of the phone, and the GSM version is not compatible with CDMA networks.
