Dual standby for data-only + call-only
I have a SIM card that I strictly use for 3G/4G data, and another SIM card strictly for conventional 3G voice call/sms.
Will a dual standby phone suffice for my purpose or do I need dual active?
I.e. for dual standby, will turning on 3G/4G mobile data/WiFi prevent the other SIM from receiving calls?
It's not a problem if receiving a call turns off the data on the other SIM as I will not be browsing the Web in the middle of a call.
