yes it's using micro sim card
seller will help you to cut the sim card
actually at first I asked at another store,  they offer me 790 but bargain until 750.
after that I still decide to walk around first.. then found another shop offer me 799 with bluetooth earphone free gift. Nokia one , included music and phone call.

the brightness i set to lowest already, low battery. battery life quite poor , i not sure is it because of software problem. Just now I use auto brightness, readability under the sun is very good.
