I have four sim of this company. 3 sims are 4G and 1 is 2G. When I want fast internet speed I insert it in slot 1 and enjoy super fadt speed of intetnet. Although its price are high other network, but this operator is too good for me. Now it gives 5Gb night data free. It is its plus point. Therefore if one wants fast internet speed on their device must use this network.
