This year's 4G hit hot, said that just changed the phone to 4G, just experienced a 4G network speed! what? Now there is a new technology that allows you to communicate more easily and smoothly. This is VoLTE. With the commercial trial of VoLTE in some first-tier cities in China, this technology has also attracted more and more consumers' attention. Xiaobian is also tired, don't want it, then, what is VoLTE? How far is it from our daily life?
Let me talk about what is VoLTE?
VoLTE is actually the abbreviation of Voice over LTE, which is an IP data transmission technology. When working, there is no need to rely on the previous 2G/3G network, and all services are carried on the 4G network, which can realize the unification of data and voice services on the same network.
In other words, with VoLTE support, we can not only enjoy high-speed data services in 4G networks, but also use it for higher-quality voice and video calls.
The VoLTE technology has not actually emerged recently. It is only that the network construction and hardware follow-up speed in this country is slightly slower. The scope of commercial trials is not too large.
What hardware devices are needed for support?
According to the information currently known by Tencent Digital, there are only four products that can support VoLTE, namely Huawei Mate 7, Samsung GALAXY S6 and two mobile phones launched by China Mobile. Need to say more, Huawei Mate 7 needs to be upgraded, Samsung S6 needs software upgrade before you can use VoLTE.
As for Apple's iPhone 6, 6s, in fact, in terms of hardware, it can already support VoLTE. From the introduction of the Hong Kong version of the iPhone6/6s "voice call", they have already supported VoLTE calls. As for the reason why the Bank of China version does not have the same information description, the biggest possibility is because VoLTE has not yet been officially commercialized (currently only "trial commercial").
If the VoLTE technology is officially commercialized, the Bank of China's iPhone 6 and 6s are likely to be supported by software upgrades. So don't worry too much about iPhone users who are currently holding these two series.
If you are using the Hong Kong version of the iPhone 6/6s, you still can't use VoLTE in China. There are still network restrictions. The SIM card of the mobile phone will also have certain permission restrictions.
