You can use 3G services only in sim one.
That's what I am afraid of!
I'll prefer that it can choose 3G/2G mode by selecting the mode on setting rather than by the SIM card slot! Otherwise, I would have to swap the cards in order to get the thing done!!! Also,there is another drawback by choosing the 3G mode by the SIM slot. Since you have to swap the cards in order to use 3G mode on one of the sim card, you may have to re-certified your whatsapp/line once you are swapping your card!! That's pretty troublesome for users!!
Anyway, thanks for your help!!
