Huawei Mate 10 series of dual-card dual-4G dual VoLTE where exactly? Before understanding this issue, let us look at the development of dual-card dual-4G.
Popular Science: Dual SIM Dual 4G's 'Past and Present'
The first dual card dual 4G is based on dual-SIM dual standby mobile phone functions and gradually achieve 4G network support, the development has generally experienced the following stages:
Stage 1: Distinguish card slot, telecommunications card 4G + Mobile / Unicom 2G In the early development of dual-SIM dual-4G, the installation of SIM card needs to distinguish between the main card slot and secondary card slot. Due to different network formats, The main card slot can be used, and placed on the secondary slot mobile or Unicom card, whether or not supporting 3G / 4G, can only use the 2G network, 4G + 2G combination, which for the use of telecom card calls, mobile or Unicom card Internet Of users are very painful.
Stage two: no longer distinguish between the main card, Internet 4G + 2G Later, with the development of mobile phone hardware, broke the card slot restrictions, any operator card can be used as the main secondary card, completely solve the user of the telecommunications card However, the card 2 still can only use 2G network, using 4G + 2G combination.
Stage Three: Mobile / Unicom 4G + Unicom 3G
The third phase is optimized for China Unicom users.When the card 1 is using China Unicom or Mobile 4G, the card 2 can support China Unicom's 3G network up to a maximum of 4G + 3G on the mobile phone, resulting in a faster Internet experience.
Stage 4: Telecom / Mobile / China Unicom 4G The fourth phase of China Unicom 3G is mainly optimized for telecom users. When using a telecom 4G card, the card 2 will support Unicom 3G at the maximum, allowing telecom card users to gain access to the 4G + 3G Internet experience.
★ Stage Five: Dual SIM Dual 4G Dual VoLTE
Dual card dual 4G Dual VoLTE is the industry's latest communications solution that enables any combination of carrier operators to deliver dual SIM-compatible 4G Internet speeds (except for two telecom cards) and high-speed VoLTE HD voice calls. VoLTE VoLTE is a high-definition voice call using 4G, with better sound quality, faster connection speed, when we talk to see the HD is VoLTE logo compared with VoLTE, the traditional call needs to fall To 3G or 2G network, call delay and sound quality will be affected.
Measured: Dual SIM Dual 4G Dual VoLTE Experience
Now that Huawei Mate 10 series uses the industry's most advanced communications solutions, let's test together today whether it can really achieve the two cards at the same time connecting 4G? We will China Mobile, China Unicom and China Telecom's phone card were inserted Huawei Mate 10 Pro, the measured results are as follows:
1. China Unicom + China Mobile, dual 4G success
2. China Telecom + China Mobile, dual 4G success
3. China Telecom + China Unicom, dual 4G success
4. China Mobile + China Mobile, dual 4G success
Through the actual test, we can see that the combination of multiple operators (except for two telecom cards) can achieve the effect of dual SIM and dual 4G, and if the VoLTE function is enabled, the HD call experience can also be enjoyed. The advantage is that the Internet and call experience is better, the process is more convenient, to avoid the process of switching the primary and secondary cards back and forth in order to use the 4G network, and greatly reduce the call drop rate, which greatly improves the user experience in communications.
Secret: Huawei Mate 10 is how to achieve?
The Huawei Mate 10 series supports 4.5G technology and both cards support 20 LTE bands and VoLTE HD telephones. Thanks to Unicom 970's first commercially available dual-card and dual-4G dual-VoLTE advanced communications technology, it successfully implemented on a handset Both SIM cards support 4G VoLTE calls, bringing the same high-definition voice and video calling experience of the primary and secondary cards.
In addition, Kirin 970 can also achieve the highest rate of each operator in the world portfolio, in every corner of the world, Kirin 970 can help users get faster Internet access.At the same time, Kirin 970 also for high-speed rail and other complex communications In-depth optimization of the environment enables users using the Huawei Mate 10-series handsets to enjoy high quality voice calls with high quality voice calls over high-speed high-speed railways.
Huawei mobile phones have always been hailed as the 'best cell phone with signal' and the Huawei Mate 10 series takes the lead in realizing the dual-card dual-VoLTE experience, resulting in better call access experience and still using 4G + 2G / 3G Dual card mobile phone friends, you can consider starting a real dual 4G phone.
