The note9 smartphone not support dual active sim i.e. if we are talking on sim 1 , then can not receive call on sim2 as it is not reachable. It means that it not support dual sim simultaneously for receive or dailing call.
Hi dear, No samsung phone can receive calls on both sims together. What samsung uses is call forwarding. It will forward calls from sim 1 to sim 2 and vice versa when the line is busy. You have to activate this feature from SETTINGS > CONNECTIONS > SIM. CARD MANAGER > SMART DUAL SIM. I think you will be charged for call divert by your carrier per call.
Please enable the below mentioned procedures in order to resolve the issue:
> Enable the call forwarding in the device (Phone app>>Tap on 3 corner dots>>settings>>supplementary services>>call forwarding>>enable it.
> Enable the smart dual SIM (Settings>>connections>>SIM card manager>>Smart dual SIM>>enable it.
