Hello, can anyone confirm that if you have dual sim, you can only use data connection of 1 sim at a time , never both data connection simultaneously(just curious, it makes total sense tho)? Another thing, when I use dual sim, 1 sim is working on 3g while the other one is limited to 2g, is that correct and normal or do I have some problem with my device? Is it also possible to set which one will be working on full speed and which one on 2g?it seems to be independent from which slot and which sim, it just seems the first sim you snap in its gonna be the full speed one. Not a deal breaker but i would like a little more flexibility on sim management. Thanks everyone
