Default Android dual SIM handsets - recommendations and reviews - 08-09-2013, 16:32

Hello world,

I'd been interested in buying a dual SIM Android handset for quite a while but since most of them were of low quality or had subpar specs, I hesitated until recently when I ordered a Zopo C2/ZP980 (32GB ROM/2GB RAM version).
The only downside of the Zopo C2/ZP980 for me is its UMTS support which is limited to 850 and 2100MHz, a pretty pointless combination of frequencies as these occur together only in very few markets (afaik Australia, New Zealand, Thailand).

As you guys probably consider buying a dual SIM handset, too, here's my personal list of interesting devices:
  • Zopo C2/ZP980
    The Zopo ZP980 and C2 share identical hardware, but the later comes with Alyiun OS, a Chinese fork-off of Android, preinstalled which makes it slightly cheaper due to subsidies
    + 5" 1080p IPS screen
    + MTK6589(T) quadcore CPU with up to 1.5 GHz (other versions come with 1.2 GHz)
    + up to 2GB RAM/32 GB ROM (other versions come with 1GB/16GB or 1GB/4GB)
    + microSD slot
    + neat iPhonish design
    + UMTS support for both SIM cards
    + changeable battery
    - limited UMTS frequencies and odd frequency combination (850 & 2100 MHz)

  • Huawei G700
    + 5" 720p display
    + Cortex-A7 quadcore CPU
    + 2GB RAM
    + 8 or 16GB internal storage
    + microSD slot
    + changeable battery
    + high battery capacity (2150mAh)
    + cheap (~ € 240)
    - UMTS support only for SIM1
    - only dualband UMTS (900/2100 MHz)
    - only triband GSM support (900/1800/1900 MHz)

  • ZTE Blade C V807
    + cheap (~ € 90)
    + changeable battery
    - no front-facing camera
    - no magnetometer (electronic compass)
    - only dualband UMTS (900/2100 MHz)
    - only triband GSM support (900/1800/1900 MHz)
    - generally low specs

  • Samsung Galaxy S4 Mini DuoS (I9192)
    + 4.3" qHD sAMOLED display
    + quadband UMTS support (850/900/1900/2100 MHz)
    + microSD slot
    + GLONASS support
    - expensive (~ € 380)
    - battery not changeable
    - low battery capacity (1900mAh)


I appreciate your thoughts and recommendations on these and further Android dual SIM handsets.

Cheers

I was not totally awake and read this:
  • + MTK6589(T) hardcore CPU with up to 1.5 GHz (other versions come with 1.2 GHz)
    + chargeable battery
  • Samsung
    + quadband UMTS support (850/900/1900/2100 MHz)

A chargeable battery, how nice.

The Samsung is the only one that has two US UMTS bands.

Perhaps they do not think dual-SIM is that marketable in the US.
This makes a start though.

I've heard pretty good things about the LG E455 Optimus L5 II Dual SIM. Quad band GSM and UMTS.

Details are sketchy on the LG site but I plan on taking a look at it next time I'm in Europe.

Price wise it should be about €170 VAT in.

Since the vast majority of phones in the US are sold through the carriers and the carriers have no interest in providing multiple-SIMs, you are probably correct.

Default Brand name Dual Sim (only) available for chineese market - 12-09-2013, 21:47

e.g. the HTC one Dual Sim for the chineese market offers also a µSD-Slot!

Strangely even though HTC is located in Taiwan, but I couldn't buy it in Taipee when I was there. The chineese market seems to be large enough for manufacterers to produce and limit products to/for china.

A final note on the Zopo C2/ZP980's dual SIM functionality:
Both SIM slots support UMTS but only alternately, so one of the SIMs will always be restricted to GSM. 3G assignment can be switched under
Settings > More... > Mobile networks > 3G service > Enable 3G > Select desired SIM

All other dual SIM-related settings can be found under Settings > SIM management where preferences for voice calls, video calls, SMS and data connections are being set. "Contact binding" allows specific phonebook items to be always called/texted through one of the SIMs.

Well, if you had not started this interesting thread you [and we]
would not have found out this important bit of info---and have prevented much sim-swapping.
Could this be seen as a battery-saving feature?
