After I started about three years ago with the Lumia 800, now has the whole family Lumias in use. My wife's 925 (for Android), I myself become the 820 and my two children this year the 630th The great thing is that the operating system on all Lumias always receives the latest updates and therefore a unified system updates for all of us is in use. As you can share and help each other well. Since I could no longer hold a Smartphone my two sons, I opted for a controlled introduction into the smartphone world. And here offers Windows Phone the fun way the smartphones of the children to associate with my account. This is called Family Safety and means that I am the administrator of the two Lumias children. Here I can then block paid apps and set rating limits. To the 630 itself, I can say that it is our requirements in every respect, is well made and the operating system quickly and without interference giving good service. For an entry level smartphone, I can therefore recommend the Lumia 630 without hesitation.
