So far none of the small or big brand mobile companies made a dual sim mobile that supports 3G on both sims. One must be W+G and other must be G only. This is to save the battery life of the mobiles and also to prevent the 3G signal interferences (read somewhere online). So until the big brand flagship mobiles comes up with altogether a different technology that has no signal interference effects, you have to live with 2 different sim radios. Even if we move few years into the future, the primary sim of a dual sim mobile will support 4G and the other one will support only 3G or 2G for the same signal/radio interference purposes.
Hope this answers your question. Hit thanks button if this clarification deserves it.
