On April 27, a netizen of the Communicator Home said that his iQOO 3 was recently upgraded to the Origin OS Ocean system based on Android 12, and found the telecom VoNR switch in the developer options, but it would still switch back to the 4G network when the actual call was measured.
Xiao Lei learned that iQOO 3 is equipped with Qualcomm Snapdragon 865 flagship chip and X55 external baseband, the netizen learned through customer service that iQOO 3 confirmed that it supports telecom VoNR, if the call is still switched back to the 4G network, it is likely to be because the region has not yet been opened. Some netizens said that the same VoNR option also appeared in the iQOO Z3, which is equipped with Qualcomm Snapdragon 765G and integrated X52 baseband.
It is worth mentioning that the OnePlus 8, which is also equipped with Qualcomm Snapdragon 865, also has a VoNR switch in the developer options, which shows that 5G models equipped with 865 and X55 baseband can support this technology. In the use of 865 models of small partners, if the VoNR switch is not found, it is estimated that it is because of non-telecom cards, or the system has not been updated.
At present, VoNR can only support Qualcomm 865 or newer models, and MediaTek and Kirin's newer Kirin chips can also use this technology. However, Qualcomm Snapdragon 855 also has a part of the 5G model equipped with X50 baseband, but it may be because it only supports NSA non-independent networking, and it is expected that the follow-up will not support VoNR, which is a pity.
VoNR is like VoLTE in the 4G era, allowing users to keep the network uninterrupted during the process of receiving and receiving calls. Friends who don't play games may not think much of this, but for small partners who play games, the relevant technology can ensure that the game will not drop during the call.
Now China Mobile, China Telecom, China Unicom have begun to vigorously promote 5G signal coverage and the popularization of VoNR technology, it is expected that in two or three years, VoNR technology will become highly available in all regions of the country, at least to solve the problem of games and phone calls can not be combined.
With the larger the number of 5G base stations, the wider the coverage of 5G signals, the so-called "5G signal is not as good as 4G" has long ceased to exist, coupled with the Ministry of Industry and Information Technology's vigorous promotion of speed and fee reduction, we can no longer think that 5G is expensive and useless.
