Sprint 4G Rollout Updates
Thursday, August 2, 2018 - 12:01 PM PDT
It's been a long time coming for Sprint through many trials and tribulations. Now it's finally here!
S4GRU was able to obtain confirmations that Sprint is finally ready and prepared to enable Voice over LTE (VoLTE) for subscribers to manually opt into in select markets across the country this coming September. See list at the bottom.
As a refresher here are some of the essential points about VoLTE applicable to Sprint:
- Calls placed over VoLTE will have the QOS tag unlike the current Calling Plus configuration on numerous Sprint devices
- Like Calling Plus, VoLTE will have no fallback to the legacy 1x voice network. Calls will drop if the LTE signal drops.
- The voice codec is AMR-WB which one can experience with Calling Plus calls and matches the other carriers VoLTE setups.
At this point and time S4GRU does not have a list of compatible VoLTE devices though we do speculate that any device currently running Calling Plus should be able to tap into that very same IMS core Calling Plus utilizes via true VoLTE. In addition, recent Apple iPhone's seems like a sure bet as some users have already experienced VoLTE in live field tests conducted by Sprint. For the non Sprint branded BYOD devices like Google Pixels or unlocked Moto devices the future is quite murky indeed.
