Redmi Note5 as the current millet's main promotion of the thousand yuan's bucket machine, at the beginning of the release of the official will be its full Netcom 5.0 as one of its main selling point. By that time, Xiaomi co-founder and president Lin Bin on Weibo's straightforward ' The explanation, supports the entire Netcom 5.0 red rice Note5 to be able to dual-card dual standby dual 4G, users can play games while calling, will not be dropped.
Red rice Note5 Now, Xiaomi’s mobile phone official has released a long article today, detailing a total of 5.0 questions and six questions for everyone. Let's take a look.
1, What is Netcom 5.0?
Compared to Xiaomi's Netcom 4.0 launched last year, Netcom 5.0 can be said to be a leaps and bounds upgrade. Because Netcom 4.0 only allows Unicom to upgrade as a secondary card to support 3G networks, and the entire Netcom 5.0 is directly into the dual card Dual 4G era, that is to say, two 4G signals can be directly seen in the notification bar of the mobile phone, ensuring that the dual card is at the same time 4G in the network.
Of course, the premise is that you need to ensure that the 'Enable Dual 4G' button is kept on in the dual card settings.
Full Netcom 5.0 2, dual 4G card standby at the same time, which data traffic?
At the time of Netcom 4.0, the SIM card set as 'Online' in MIUI will be considered as the main card and enjoy the status of the highest 4G in the network. Data traffic is completed through this master card. The secondary card is based on the dual card combination. Enjoy different 2G or 3G networks.
Today, all Netcom 5.0 dual cards are on 4G networks. Actually, they do not consume two cards at the same time. It also requires users to specify one of them as 'Internet access', which means that there will only be one data path, which will not lead to Both cards consume traffic at the same time.
For example, with mobile + Unicom's dual-card device, the mobile card's function is selected as 'Internet access', which consumes China Mobile's data traffic packets.
3. What is the significance of dual 4G if the traffic only takes one card?
Many people may read the last question and they will have such confusion: If only one card is used as 'on the Internet', what is another, even 4G, useless?
1) Dual VoLTE
Here we need to introduce VoLTE, which means high-definition voice calls. Today's Xiaomi mobile phone has full support. When your signal bar shows the HD logo, it means that this is an IMS-based voice service. Popularly speaking, it is through data traffic. To call.
Therefore, when Netcom 5.0 is adopted, all secondary cards can also be connected to 4G networks, and VoLTE high-definition voice calls can also be supported. The two HDs in the following figure are displayed, which is dual VoLTE.
Full Netcom 5.0 2) Calling the Internet is correct
When both cards can support 4G and VoLTE, the master and slave cards can ensure normal network usage when they are in an incoming call state. In other words, when you play a game, you will not have any influence. Before, if the secondary card The call network is disconnected, which may be a fatal blow to the King's glory and chicken players.
4. What are the benefits of dual VoLTE?
The benefits of VoLTE may be known to many people. For example, when you make a call, you can also access the Internet at the same time. The connection is fast and the delay is small. In addition, the VoLTE voice sampling is 16 kHz. Compared with the traditional GSM voice sampling 8 kHz, it also has a qualitative improvement. This means that the voice quality of VoLTE calls is better.
The millet MIX 2S's full Netcom 5.0, using dual VoLTE, that is, both cards support VoLTE HD calls, both cards can receive high-definition call quality regardless of which call.
5. Why doesn't my MIX 2S have dual VoLTE?
VoLTE HD voice calls need cell phone hardware support, but they can be used without a card. First you need to understand the local network deployment status, confirm whether the operator has deployed VoLTE network, and then you need to apply to local operators to open VoLTE service. .
Take the Beijing area as an example. Currently, only China Mobile uses VoLTE service, and the service can be used for free. The other two operators, Unicom and Telecom, are not yet commercially available. So currently dual-VoLTE can only be supported by two mobile cards. When the other two operators get settled, it is really any combination of dual VoLTE.
6. What is the status of telecom card support?
Full Netcom 5.0 For Millet MIX 2S Full Netcom 5.0, the current mobile and China Unicom support is the easiest, regardless of mobile + mobile, mobile + Unicom, Unicom + China Unicom have no problem, can support dual 4G network.
The only telecommunication card is relatively special. Theoretically, the full CNC 5.0 telecommunication card can support VoLTE when used as a secondary card. However, since China Telecom's VoLTE service is not yet commercially available, the current telecommunication card, as a deputy card, can only stay at CDMA 1x for the time being. , which is the telecommunication 2G network. If the dual-card configuration of the telecommunications + telecommunications, the secondary card is temporarily unavailable, only for VoLTE.
Full Netcom 5.0 Therefore, if there is a combination of telecommunication cards and you want to use a telecommunications card as a traffic card, then you need to change the dual card function to 'Internet access' in the MIUI settings, that is, the main card mode, and telecommunications will use 4G network.
