I have noticed that in my previous phone S20 FE 5G dual sim there was an issue - When i get call in sim1 ,evenif the call is disconnected, SIM 2 becomes not available and vice versa. Signal bars shows full coverage. I have to either switch off or turn the flight mode on and off to get the other line active.
The same issue with S21 Ultra also. Anyone else have this pbm and is there any solution.
I am using Samsung DUOS devices for very long time and I have never faced this issue. In almost all dual sim devices, when we receive calls in one sim, the other sim can't receive calls until the first call is disconnected. Samsung introduced a solution for this issue and they named it as Dual Sim Active(now renamed as smart dual sim). It uses call divert feature to divert calls from the inactive SIM to the active sim. To conclude, calls won't connect when one sim is active, but it should immediately available when the call is disconnected. Double check if you are able to receive calls atleast after two minutes once you disconnect the call. If not please contact Samsung for remote support.
Hi thanks for the response. Yes me too I am with Samsung phones since S2 and the pbm I noticed in the phones S20 and S21 so far. I checked with another friend who uses S20 Ultra he got this issue too. He restarts phone often to get the line back in.
