Huawei put out a couple of Android-powered members of the Honor line. The first is a 5.5" phablet, the Honor 3X, while the other is a 5" smartphone, the Honor 3C. Both feature dual-SIM connectivity.
The highlights of the Honor 3X are a 5.5" IPS screen with 720p resolution (Huawei claims a 1080p screen would have used 20% more battery juice), MediaTek MT6592 chipset (octa-core Cortex-A7, 1.7GHz) with 2GB of RAM, 13MP and 5MP cameras on the back and front and a 3,000mAh battery.
The 3X has an odd type of dual-SIM setup that's just right for China's market – one slot uses good ol' miniSIMs, while the other is a microSIM slot. Both are 3G-enabled and both support regular 3G (China Unicom, also worldwide 3G) and China-specific 3G (the China Mobile kind).
The Huawei Honor 3X will cost CNY 1,700 ($280) off contract.
The Honor 3C has more modest specs, but it costs less than half the price of the 3X. For that kind of cash you can have a 5" LPTS screen with 720p resolution, a MediaTek MT6582 chipset (quad-core Cortex-A7 at 1.2GHz) with 2GB RAM running Android 4.2, the same 5MP front-facing camera and a Sony 8MP f/2.0 shooter on the back.
The 3C also supports the global and China Mobile kinds of 3G with its two SIM slots. There are two versions – one with 1GB RAM and one with 2GB. Both have 8GB of storage and a microSD card slot.
The Huawei Honor 3C will be up for pre-order tomorrow for CNY 800 ($130) or CNY 1000 ($160) for the 1GB and 2GB versions respectively from JD.com and Vmall.com.
you cannot enable 3G on the second sim unless you swap the sim cards. Sim Slot 1 - 3G/2G and Slim Slot 2 - 2G Only
Honor 3C is a dual-sim phone so it can support 2 micro-sims. However, only the first sim will support WCDMA(3G) and GSM(2G) while the other will only support GSM. LTE will not be supported at all.
