A smartphone was purchased in installments, which I categorically did not like, with which I had problems installing some applications. By law, the buyer has the right to return even a fully working and serviceable phone, if only because he just didn't like it, which I was naturally denied. I think that after the expiration of the contract, I will change the telecom operator, although I have been with this operator for 14 years
The network quality is very poor, most of the LTE network speed does not exceed 1.5MB, in 3G the speed is higher, and the headovers work very poorly, there are delays of 10 seconds, along the highway the Internet disappears altogether!!!
