Hello,
I've searched these forums, I've searched Google and I can't seem to find a comprehensive answer. So I'm turning to the amazing Phandroid community to help me.
I used to have a phone on VZW that did SVDO, as I understand it, voice over 1x/2g data via 3G simultaneously. This was a rarity at the time on CDMA & I remember it being a selling point of GSM networks as SVDO was supported natively.
Fast forward and now we have fairly good 4G saturation on the largest wireless carriers and now we have SVLTE a VoLTE. I get that the former is Simultaneous Voice over LTE and the latter Voice over LTE (a sort of carrier specific VOIP over the data network that is being marketed as high def or advanced voice).
What I don't understand are the specifics of how those latter two differ, other than the VOIP and how this affects reliability. I read that the older GSM SVDO caused more dropped calls due to the strain on the network and now, if one wants to use VoLTE, at least on CDMA, they run the risk of dropping calls anytime there is a switch to 3G as this handoff is currently impossible. Is it the same for the GSM based LTE?
My personal situation makes cell phone coverage and reliability an absolute requirement. And, I've found that I often use simultaneous voice and data - over whatever networks they need to use. But I can't be dropping calls all the time because VZW can't keep a call going over LTE when one passes into a 3G area. I'd really love to hear your thoughts on these technologies and their respective networks, how they behave similarly or differently. I'd like to understand how the differences in either the networks themselves or the various simultaneous voice and data technologies affect reliability and call performance.
I'm in a situation where I can choose either of the two large networks (neither of the others have even bare coverage in my area) and may need to upgrade my phone, even if it's not for a new one. It seems that things have switched up and where AT&T used to be less expensive, VZW is offering more data for less. If I didn't have pressing issues requiring supreme reliability, I wouldn't give it much thought and I'd go with the best price. But I don't want to do that if I'm losing reliability with VoLTE on Verizon. I'm currently using a Samsung Galaxy Note 3 on the VZW network and I've noticed several times a week my phone will be in 3G even though we have great 4G VZW LTE (although maybe not XLTE). I don't know if this is because of the SVLTE that the Note 3 uses (since I don't full understand the how of that tech) or if it's just our area. But it's enough to make me worry if VoLTE will be dropping calls all the time. I really need to understand all of this to be able to choose both the network and the Android phone that will be best for my situation.
If I've missed a great link that explains this, please feel free to point me to it. I just thought it would be helpful for me, and others if we could have a thread that covers all of these technologies together and in comparison.
Thanks so much!
