The tablet supports working with 2 SIM cards, which is atypical for such a device. You need to know that this model can be presented in several varieties, where the built-in memory is 4 GB, 16 GB or 32 GB, and there may be no 3G connection at all. With the help of the newly appeared Russian firmware, you can make calls, send SMS, MMS and much more that is available only to the phone. A powerful processor and an operating system that can be updated "over the air" (when connected to Wi-Fi) make working on the Internet pleasant, fast, and easy. The processor does not support "heavy" games that can be downloaded and installed, but they will "hang". This is confirmed by the 1 GB RAM, you can install microSDXC up to 64 GB.
The battery lasts for 2-3 days of normal operation. A 5 MP camera takes mediocre pictures, and a 0.3 MP rear camera gives a blurry image on Skype.
