After the purchase, I inserted a SIM card for verification, and I managed to get it (with all the accuracy and use of tweezers) only together with the contacts that fit the SIM card. There is no snapping when you click on the SIM card. The adapter with the microsym is hooked. I had to change the module into which the SIM card is inserted. On 4pda there are firmware for the Russification of the interface. It was cheaper in a well-known Chinese store, but taking into account promo codes and cashback from Tinkoff, it turned out to be cheaper than from China. Once set up and forgotten, works flawlessly. Wi-fi reaches 30 meters from the installation site and even through the wall. I recommend. For giving a great option.
