sprint, nexus 6p or 5x, simultaneous voice and data possible?

[darckhart]

hi all, checking if anyone currently on sprint with a nexus 6p or 5x (or equivalent competitive smartphone) can do simultaneous voice and data? thinking about picking up a 6p if it can.

It seems many of the new "spark compatible" phones only have one radio for both cdma and lte and therefore can no longer do simultaneous voice and data.

this is true.... none of the sprint spark phones can do simultaneous voice+data (technical limitation). nexus 6p and 5x cannot do simu voice+data on sprint

workarounds

1. Call via VoIP apps (Skype/hangouts/....)
2. Can do voice + wifi(data)
3. Move to another carrier with this feature (ATT/Tmobile on 3G or VoLTE, Verizon with VoLTE)
4. Carry a second phone

Verizon users may have stability issues with VoLTE (LTE network is not as expansive as CDMA... if you lose LTE signal, call drops)....

doubt Sprint will see VoLTE anytime soon because Sprint's LTE network is much smaller than Verizon and will run into the same issue as Verizon (lose LTE signal on VoLTE = call drop)

thanks for reply!
I was hoping with the nexus having two radios it would get around the issue, but it seems that it's not the phone's fault; it's the fault of how Sprint implements their CDMA an LTE. If you're in LTE, ECSFB will auto drop the LTE connection to switch to CDMA so you can take the call. And I guess since that takes precedence, you can't get back onto LTE.

(I feel VoLTE is a kludgy solution anyway so I'm not surprised there's call drop issues.)

only one hardware modem/antenna chip though... that's the problem... i think it's very technically challenging to design two hardware modem/antennas with tri-band LTE support+ CDMA

VoLTE is the future though..... there is VoLTE->3G GSM handoff (so I blame CDMA )
