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 one: Distinguish card slot, Telecom 4G + mobile card / Unicom Vice 2G card
Early in the development of dual-SIM dual-4G, the installation of SIM card needs to distinguish between the main card slot and the secondary card slot.Because of the different network formats, the telecommunication card can only be used in the main card slot, and the mobile card or the Unicom Card regardless of whether it supports 3G / 4G, can only use the 2G network, 4G + 2G combination, which for the use of telecommunications card calls, mobile or Unicom card Internet users is very painful.
Stage two: no longer distinguish between the primary and secondary cards, Internet 4G + 2G
Later, with the development of the hardware of the mobile phone, the card slot was broken, and any operator's card can be used as the primary and secondary card to completely solve the problems of the telecom card users. However, the card 2 still can only use 2G network and 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 Four: Telecom / Mobile / Unicom 4G + Unicom 3G
The fourth phase mainly aims at telecom users' optimization. When card 1 uses telecom 4G, card 2 supports up to Unicom 3G, so that telecom card users can also get 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
Part of the contents and data from Huawei Kirin: Huawei_Kirin Official WX can be seen through the actual test, a variety of carrier combinations (except for two telecom cards) can achieve the dual-card dual 4G effect, if VoLTE feature open, but also enjoy high definition Call experience Dual SIM Dual 4G Dual VoLTE biggest advantage is that the Internet and call experience better, the use of more convenient to avoid the use of 4G network switch back and forth between the primary and secondary card process, but also greatly reduce call drop rate, great Improved 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 dual 4G dual VoLTE leading communications technology to be successfully implemented on one 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 mobile phones 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.
