I use dual sim at F5122,
when i set 4g at sim1,
the sim2 only 2g(GSM) can be used,
so, i can not use 4g+3g at the same time.

That's how Dual SIM is working, you set one SIM as your data SIM and adjust if you want to receive 3G or 4G on it, and the other SIM is automatically set to be a voice only SIM which is mainly 2G. You can switch between your 2 SIM at anytime and use any of them as the data SIM without removing them.

@JimLin

No, those phones you mentioned does not support this too. As far as I know, there is no phone that can allow 3G or 4G data on both SIMs at the same time.

On a side note: why do you even want to have 4G/3G on both SIMs at the same time?

Oh, from the beginning I was wondering why would one want internet on both SIMs simultaneously!

There you go then, you got your answer yourself.

Does Xperia X supports 4g+4g. If no then any further plans going to implement this. I read some where it can be implemented using software updates if phone has desired hardware
