Wenn you dial a number you can choose from which SIM the call is operated from.

That's what I'm doing, but I can't use Internet while I'm calling, and I don't know why.
SIM2 is already set for mobile data by default, and SIM1 for calls and SMS.
When I call with SIM1, Internet access is instantly down, but the data icon is normal.
It affects both the phone's apps and wifi tethering.
Thanks

So, I found out, it's a limitation of dual stand-by (i.e. how all dual SIM smartphones work) : https://en.wikipedia.org/wiki/Dual_SIM
