Reliable Dual-SIM mode, Windows 8.1 finally useful

Who can find a reliable dual SIM operation is important and who do not bother the little limitations of Windows AppStore, which I can only recommend this smartphone. I had previously tested two different Android dual SIM smartphones (of Mobistel and Alcatel). Both came regularly to disconnections and non-accessibility when changing from domestic network to roaming (or vice versa). Probably the dual SIM implementation of Android is weak on this point.
By contrast, there is the Nokia 630 dual SIM no problems, not even in the border area between two countries. People who live on a border, and which are plagued by constant uncontrolled power exchange of their mobile phones to know what I'm talking.

So far, I am fully satisfied with the device in all material respects, I expect as a non-gamers games from a smartphone.

*** Pluses ***
- Easy start-up, however, there must be a Microsoft account or be created, if you want to use all functions. This is for Android (Google Account) and Apple as well as otherwise.
- Many apps preinstalled, including WhatsApp, annoying preinstalled Zwangsbeglückungs apps are not available.
- Windows Phone 8.1: Most flaws that were still present in 8.0 are eliminated. For example, the volume of apps and phone can now be controlled separately. Intuitive operation without problems so far, a lot of settings.
- Good spelling correction and useful word suggestions while typing text.
- Very long battery life even with two active SIM cards (3-4 days under normal use no problem).
- Processor fast enough for normal functions and Internet browser (games I do not use, therefore no statement about it).
- Very good connection and voice quality.
- Device memory and micro SD card are very easy via USB connection to a Windows PC available, no annoying detour via add-on software (I want to mention any names).

*** Minuses ***
- The plastic back panel also includes the side surfaces, the whole works by something cheap.
- No hardware camera key and no flash LED.
- No Signal LED to indicate incoming messages.
- Display resolution could be better, but for the price is perfectly fine.

Conclusion: A highly recommended phone for people to whom a reliable dual SIM operation and the basic functions of a smartphone with a long battery life are more important than Super performance in processor, display and camera. Given the low price, this device is a "secret" in the dual SIM range.
