I have been using this since 2 month. adding a very important point to my review ( based on 4 months of usage) nBoth sims DO NOT work in certain areas of the city! nAt times, one of the sims automatically stops catching network, but the same put in a different phone gives full network. This is an issue for me, because it’s happening in the area I live! nnI purchased it from a shop two months ago.
