We like: this phone is good when you are traveling and want to add a local prepaid SIM card. Indeed, the presence of dual SIM is very significant. In addition, WhatsApp allows you to stay in touch cheaply by messages with your family or friends. The QWERTY keyboard is more suitable for writing messages.
The design is very nice. It's a pretty nice phone somewhat reminiscent BlackBerry, which appeals to young teenager (s).
We like least: the slow menus. Access to menus is very long, like most Nokia unfortunately. There is always great delays. And when one launches Facebook or WhatsApp dedicated applications, it's not getting better.
The battery life is not great either for a phone of this type. Especially when both SIM cards are in use. It will keep two to three days at most in normal use with two SIM.
The charger is still not USB, it remains the standard Nokia chargers. But taking it! We must therefore buy a dedicated cable for that next, it's a shame I think.
In short, a good basic for travel but as a secondary phone. You can not do much with the slow and menus will make some people mad. The shape of the device is otherwise nice and he keeps well in hand. The little touches that are handy and play the game.
For my personal experience: I used it for a period of four months in China in addition to my iPhone. I quickly put the Chinese SIM in my iPhone and the French in the SIM Nokia (slow Menus WhatsApp was too). My French calls and SMS so passed by Nokia. For apps I passed by the iPhone.
