I'm Smartphone Learn (Samsung Galaxy S3, iPhone 3GS / 4S / 5) and then the start-up of Lumia 630 DS went pretty fast. Criticisms of other reviewers I can not understand. Under each operating system (Android / IOS / W8.1) you have to create a respective account in order to use the part. To criticize I think that's covered.
The quality of the Nokia Lumia 630 DS (it was in black) is impeccable. For this price a perfect smartphone. W8.1 I like better than Android as an operating system in smartphones. But is a matter of taste.
Meanwhile, the mobile phone of mine has been fully operational. Email accounts are set up and - this is awesome at W8.1 - merged into one. The Zusammenfüren is übrigends individually. You can combine mail accounts as you want.
Sim1 is with me in the T-Mobile network and Sim2 in the E-Plus network. Thus, I am to be well prepared to be easily reached. Although the Nokia Lumia 630 DS has no LTE on board, unlike the Lumia 635, but I put emphasis on Dual Sim.
Personally, I can issue a buy rating for the Nokia Lumia 630 DS. It is the first smartphone where übrigends NOKIA draufsteht, but that is entirely by Microsoft.
