Dual SIM standby -- data and calls on different SIMs I wanna ask about Dual SIM standby 4G phones, particularly Lenovo P70 if that makes a difference.

If I have two SIMs: (A) with a call and SMS tariff, (B) with LTE data.

If I browse the internet on (B) and someone calls me on (A), will I be notified of the call? And if so, when I answer the call, will I disconnect from the internet?
As far as phone calls are concerned, when you use SIM1 for a phone call, SIM  2 will be unavailable to receive calls or messages. Anybody that tries to call, the call will not go through.

As far as Data connection is concerned, when you use SIM1 for Data, and you get a call on SIM2, data connection is automatically put on hold, and will continue when the call on SIM1 is finished.
